EXTERIOR LIGHTING

16 complaints

The back up lights when in reverse at night are inadequate to safely back the vehicle up. This is true whether one is using the rear window and rearview mirrors or one is using the back up camera. No more than 10 feet of area behind the vehicle can be seen by using these lights.

THIS IS AN ISSUE THAT HAS BEEN UNDER RECALL SINCE JUNE 2025. WE HAVE HAD THE DEALER DO THE RECALL, HAD OVER THE AIR UPDATES AND IT STILL CAUSES ALL THE ADVANCED DRIVER ASSISTANCE SYSTEM SCREEN TO GO BLACK AND DISABLES THEM. DEALER MSYATES ALL RECALLS HAVE BEEN COMPLETED.

When backing up my car from the driveway during rain it continuously applies phantom braking making it impossible to move the car. Turned off the rear autobraking but it still doesn’t help. It’s very dangerous. This is the same case for all the electric vehicles manufactured by GM and reddit posts exist for Equinox EV, Blazer EV, Honda Prologoue, Acura ZDX

At multiple times when raining, the Automatic emergency braking system activated for no apparent reason as no hazard could be determined.

Dec 20, 2024

While we're driving the vehicle the adaptive cruse control was on. As we approached a vehicle ours started to slow down from 55mph to where it almost braked all the way about 2mph. The vehicle in front of us braked completely and was stopped. As soon as they were stopped, Our vehicle tried to rapidly accelerate into the back of it where we had to intervene and slam on the brakes. If we didn't do this there would have been an accident due to our adaptive cruise control failing. This has happend twice to us. Taken the vehicle to the dealership and they cant replicate the problem so there is nothing to fix. This is something that needs to be Investigated before an accident occurs.

The main driving display in my 2024 Cadillac Lyriq has faulty software or light sensor calibration - the vehicle automatically dims the screen (including the speedometer) to unreadably low levels, is extremely slow to respond to changing lighting conditions and time of day (the display changes between day and night modes automatically but is constantly confused by lighting conditions). This happens most often at dawn and dusk. I will be driving in bright sunlight with the sun glaring in my eyes, and the screen will think it's night and be dimmed way down to about 20% brightness. Customers have no way of overriding this. There is no setting to disable automatic brightness, and some customers have taken the time to manually unplug the daylight sensor on the dash to resolve their issue. Additionally, the system is extremely sensitive to going under overpasses, which will immediately dim the entire system to about 20% brightness and stay that way for a long time after returning to bright sunlight. This also happens when pulling into my garage, where the display dims down so low that I am unable to see the safety cameras around the vehicle in order to park my vehicle correctly. GM has been made aware of this issue, and they've been aware of it for years. I've spoken to GM directly, and they say, "a fix is coming," but it's been years and nothing has been done. They've issued multiple software updates, none of which address the problem so far. Subsequently released vehicles, like the Optiq, have this issue resolved. GM knows how to fix it, and that's an issue; they just do nothing about it. This is a very well-known, very widespread issue for other Lyriq owners. You can find chat chains on Reddit discussing this issue, and even one where multiple owners talk about starting a class action case on it as it involves vehicle safety. I'm attaching photos of what my display looks like when the sun is out in the morning. It displays the same behavior at dusk.

We were exiting a parking garage when the car suddenly slammed the brakes on in the path of traffic and lost all electrical power. We could not get the car to turn back on or even get it in neutral to move it out of the path of traffic. Our [XXX] old got locked in the car because the car had zero electric power and someone helped us figure out how to unlock the car with the physical key. We were stuck for four hours because no one could figure out how to get the car out of the garage. If this had happened going at a high speed this could have caused a deadly crash, and it happened without any warning.

When driving, the infotainment screen glitched. This also affected the main instrument cluster containing information like speed, and inhibited any ability to control certain functions like the headlights. While the infotainment screen was scrambled, this was not a perceived safety issue [except that cameras could not be seen] However, the main instrument cluster was concerning. Correct speed, gear position, blinkers, etc were not shown or delayed. [e.g. when going approx 30 mph, the cluster stated approx 15 mph]

Jan 28, 2025

The vehicle's instrument panel automatically dims excessively at dusk and dawn. When it does this, the speedometer and other information in the dashboard are not visible. There is no way to adjust the brightness any higher and no way to disable this auto dim feature. This is, to my knowledge, a known software bug that has persisted for close to two years without any effort by GM to rectify this safety issue.

BACK OVER PREVENTION,FORWARD COLLISION AVOIDANCE

5 complaints

Continuing problem with both front and rear emergency braking. Primarily when it is raining and vehicle is put in reverse violent and unexpected emergency braking will occur for no apparent reason. This will happen several times. Also, when backing out of driveway on a slant, rear emergency braking seems to sense the street and brakes are applied violently. This situation has also happened going into driveway on a slant for front emergency braking. Have informed the dealer several times of this problem and they say that Cadillac has not fix. Very distressing and dangerous for whip lash of adults and children.

I have had two incidents with the automatic braking system occur in a short period of time. The Lyriq is not a car that I drive very often so when the incidents occurred in the last 2 of the 3 times of driving the car it makes me scared to drive the car again. The first incident occurred while driving at approximately 35 mph. The road I was on had 4 lanes with a turn lane in the middle dividing the 4 lanes with 2 lanes on each side of the turn lane. The road carries moderately heavy traffic as it has many businesses (fast food restaurants, strip malls, etc.) I was driving in the left lane when a truck in the on coming traffic entered the middle turn lane and a vehicle ahead of me entered the lane to the right of me. Neither vehicle crossed the line of the lane I was in. This is normal traffic for the type of road I was on. I know there have been reports of rain interfering with sensors in the past, but this day was clear. My vehicle flashed a red collision warning and engaged the automatic braking system. This was scary as heck. It was very jarring to me and my passenger. Next incident I was parking along a curb. So this time I was driving under 10 mph. I was backing up and there was a hand rail along on a walkway on the curb. There was no way I would hit the railing as it was several feet from the roadway. There was no warning in my car when it engaged the automatic braking system. Even though I wasn’t traveling very fast it was very jarring and my neck was still hurting from the last incident when it engaged the automatic braking. When the car engages the automatic braking system it sounds as though it has hit something or someone has hit you. It’s very confusing. I reported previous incidents to my dealer and they said that the sensors were sensitive and they supposedly did some sort of fix, but frankly I’m concerned what could happen as these incidents have quite seriously been a pain in the neck for me.

The contact owns a 2024 Cadillac Lyriq. The contact stated that while reversing from the driveway, the brake pedal was applied without driver input. The contact stated that the vehicle detected an unknown object, causing the brakes to be applied, but the contact determined that there was no object behind the vehicle. While driving at 50–60 MPH, the brakes were applied without application. There were unknown warning lights illuminated. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The computer was reset. The vehicle was not repaired. The manufacturer was contacted, but further assistance was not provided. The failure mileage was approximately 100.

I am submitting this follow-up to document new information and continuing concerns regarding my 2024 Cadillac Lyriq EV, which experienced sudden unintended acceleration during a parking maneuver. GM and its claims administrator (ESIS) have now completed their review and issued a denial letter on October 31 2025, stating “no defects were found.” However, the denial included no supporting technical findings, analysis, or data explaining how that conclusion was reached. Despite multiple written requests, GM has not provided the following key event-data modules: – Brake System Control Module (EBCM/iBooster) export (brake pressure, pedal position, brake override flags) – Propulsion/Drive Control Module data (torque request vs actual torque and accelerator input) – Front Camera Module metadata (timestamps and event record IDs) Additionally, several data discrepancies remain unresolved — including mismatched timestamps between the ASCM and FCM reports and camera images that do not correspond to the actual crash scene. On October 29 2025, GM publicly announced Customer Satisfaction Program N252521980, covering certain 2023–24 Cadillac Lyriq and 2024 Chevy Blazer EV vehicles for a Brake System Control Module software update due to possible brake-control performance issues. Because my incident involved loss of braking response, this recall appears directly relevant. I have requested confirmation whether my vehicle is affected and whether this module was analyzed in GM’s investigation, but have not received a reply. I am requesting that NHTSA review GM’s handling of this case to determine whether the engineering review was complete and whether the vehicle’s BSCM or related systems could be implicated in unintended acceleration or brake override failures. GM Case #1092995 – Submitted to ESIS/GM Product Investigations Group. Thank you for your attention and for documenting this matter in the defect database.

On [XXX], my wife was driving our 2024 Cadillac Lyriq RWD (VIN: [XXX] ) in stop-and-go traffic on [XXX] at 5-10 MPH. She was maintaining a safe distance when the truck ahead suddenly stopped. She pressed the brakes firmly, but the vehicle failed to stop, resulting in a collision. Despite full brake application, the car did not stop as expected. The Automatic Emergency Braking (AEB) and Forward Collision Alert (FCA) systems did not activate. No alerts or braking assistance occurred, even though these safety features were enabled. Her passenger witnessed her screaming that the brakes were not stopping the car. The crash caused front bumper damage, and a police report was filed. Investigation & GM’s Response GM inspected the vehicle but refuses to provide testing details. The Crash Data Report does not show any recorded braking event or safety activation, despite my wife pressing the brakes. GM has not explained: Why the brakes failed to stop the vehicle. Why AEB and FCA did not activate. Why no braking data was recorded despite the collision. Safety Concerns My wife is now afraid to drive the vehicle and refuses to continue driving it after repairs. I may be forced to break my lease or sell the car due to this serious safety concern. This raises major safety risks for other Cadillac Lyriq owners, especially with known braking-related recalls on 2023 and 2024 models. Request for Investigation I urge NHTSA to: Investigate braking system failures in the 2024 Cadillac Lyriq. Review AEB and FCA non-activation during low-speed collisions. Determine whether GM is withholding data or failing to acknowledge a defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Crash: 1

When approaching a red light at 5-10mph, I engaged the brakes, but the brakes did not work and the automatic breaking didn't work either, leading me to rear end the car in front of me. There were no prior warnings lights or notices, and the breaks were working properly before and after the accident. The car was towed to the dealership for inspection, but they could not find anything wrong and have contacted GM for further inspection.

Crash: 1

I was driving the car on the turnpike and out of nowhere the rear collision system went offline and the automatic breaking was triggered while I was going 70 mph in rush hour. The brakes started to smoke and smell and the the warning of ‘breaks overheating. do not drive. call service’ happened. I proceeded to narrowly avoid many cars on the road by having to cross three lanes of traffic over to the shoulder and the car was fully smoking, I quickly turned it off I got out and stepped away. After some time when I felt safe returning to the vehicle I turned it back on and was still showing breaks were overheated message and then was forced to get the car towed and take an Uber home. The vehicle is only 2 months old with ~3300 miles on it. The vehicle is currently sitting at the closest dealership to the event and they are unable to work on it due to a lack of EV service provided there and they told me they are unable to have it moved to the dealership I purchased it at.

I was driving on Saturday September 3 at 5 pm over the Chain Bridge entering Washington DC. Traffic was heavy and the auto brake went on when I was about 15 feet from the car in front of me. I was using one-pedal driving and when I pushed on the gas slowly we started slowly moving forward. I was traveling around 3 or 4 miles an hour and the car would not slow down when I took my foot over the pedal. One pedal driving apparently stopped working. I then applied the brakes gently and the brakes did not work. I then pushed the brakes hard and still no brakes worked. I tried pumping the brakes and nothing worked. The car gently ran into the car in front of me causing no damage to the car in front and he kept on his way. My front grill was cracked and bumper was slightly damaged. The signal on the dashboard said parking brake engaged which it was not. While the auto safety brake engaged minutes earlier when it was not needed it did not work when the car was drifting uncontrollably into the car in front of me.

Crash: 1

While driving the car on 2 separate occasions, the breaks failed and the car would not stop completely. Twice I have taken the car to the dealer to be repaired and the car is currently at the dealer.

Apr 14, 2025

As I approached a stop sign and hit the brake the car did not stop. I pounded on the brake but there was no response at all; it just coasted forward. The car continued to move and hit the car in front of me stopped at the stop sign. That car, a Nissan Rogue, had no damage. I was barely moving but the plastic sheet in the front of the Lyriq was cracked.

May 22, 2024

Crash: 1

There was “Brake System Failure” message on the EV’s digital display. It happened 3 times in less than a month. When it happened, I had to apply the break very hard. Otherwise, the car would not stop completely and would not hit the car in front. Top speed is limited 43 mph so I could not drive it on freeway.

Ref: NHTSA ID# 24V589/ GM Recall N242453471 Record shows that the above recall was completed on August 27, 2024. Yesterday while I was reversing my 2024 LYRIQ out of my garage I experienced multiple false automatic braking. Braking was so frequent that, I thought, driving that car at that time was unsafe and pulled it back into the garage and took my other car. It was raining at that time. False braking has happened in the past but not to a point where driving is nearly impossible.

Oct 21, 2024

Each time it rains and the car is in reverse, the emergency braking system kicks in repeatedly, and a red light flashes on the screen. The car believes there is an object or person behind the car; I would imagine because the rear camera can see the rain. It is difficult to even move the car at all, and is a major safety concern. The last time this occurred, I was backing out of my driveway at a slow speed. This also occurred backing out of a parking spot at a slow speed. I hesitate to drive this car in rain because of the issue. In speaking with the dealership's repair personnel, this occurs on every Lyriq. In fact, there was another Lyriq in for that complaint at the same time. I cannot attach photos or a video, as doing so would be unsafe. However, it can be easily re-created in any Lyriq.

Oct 01, 2024

Car has a automatic back up braking system. The car will brake hard to stop vehicle if there is an object behind it. In this case, the car was braking when there was no object behind it. This happen continously while I was trying to back out of a parking space. I could only drive forward. Finally, after a few attempts to back out of the parking space, I was able to drive in reverse. After I was able to drive forward, I tested the the car drove to a location where there wasn't anything behind me. I put the car in reverse and it did it again automatically hard braked and stopped the vehicle. I waited then tried it again and I didn't have the problem anymore. I took the car to the Cadillac Dealer. I was told there have been others who have had this same issue. Furthermore, I was told they can't fix it. Perhaps the feature can be turned off I was told. I don't see where it can be turned off. The feature is a good safety feature if works when it should. Meaning, when there is truly an object behind the car. That's my complaint This was a scary episode.

ELECTRICAL SYSTEM,FUEL/PROPULSION SYSTEM

2 complaints

Hi, this vehicle is owned by Surreal Development LLC. A company whom reverse engineers vehicle. GM has an issue in their Cadillac Lyriq's which causes a complete failure of the vehicle's communication systems without warning while driving. This issue appears to affect all Global B vehicles but it is most severe in vehicles with one pedal driving (Sierra EV, Lyriq, Blazer EV, Optiq, Silverado EV, Equinox EV, etc...) The error is likely within the vehicle's Serial Data Gateway Control Module but it is unclear. The vehicle recovers from the communication quickly (within seconds) but it causes long term adverse affects for that driving period. 1. The vehicle will light up with warnings (Service Traction Control, disengage super cruise, disengage ACC, etc...) 2. The driver's pedal will go into safety mode. 3. A "Service High Voltage" system warning may or may not appear. The safety concern is mostly in #2. When this happens it is very jarring to the driver as it drastically changes how the vehicle responds. While the vehicle may state one pedal driving is disabled many times it still indicates it is on within the controls (likely due to an error in the compounded communication fault). This can lead to the driver rear ending the vehicle in front of them or rolling over. The fault does not correct itself until the vehicle resets (powers off/on). The issue is common and affects many owners of the Cadillac Lyriq. The only diagnostic data we see are communication faults across many modules.

This is an update to my original NHTSA complaint submitted on May 5, 2025 (complaint number 11658852), regarding a complete electrical failure in a 2024 Cadillac Lyriq. While parked in a garage, the vehicle experienced a full shutdown—rendering all systems inoperable, including the door locks and windows. Most alarmingly, a [XXX] child was trapped in the back seat due to the doors being electronically locked and unresponsive. The dealership has since diagnosed the failure as a cable routed improperly near the steering column that had rubbed against a component and snapped. This severed connection resulted in the complete loss of vehicle power and emergency functions. Since that time, I have discovered multiple similar reports from other Lyriq owners online describing full system shutdowns, locked doors, and failures to start—many of which are shared on public forums such as Reddit [XXX] ). This suggests that this may not be an isolated case but rather a potential systemic defect in the Lyriq's wiring harness design or electrical architecture. I am extremely concerned that this failure mode could occur while driving, particularly at highway speeds, and would result in loss of steering, braking assist, and emergency exit options. I urge the NHTSA to investigate this issue further to determine whether a recall or manufacturer communication is appropriate. This vehicle is currently with the dealership, and I have refused delivery until GM provides formal safety assurances.

I pulled my vehicle in my garage and was lightly tapping the accelerator to get the vehicle far enough in to avoid it interfering with the garage door. I had one-pedal driving engaged so I was not using my brake pedal. Once positioned I was getting ready to put it in park and the vehicle rapidly accelerated as if someone was stomping on the accelerator. It slammed into a refrigerator I have in the garage, pushing it about 2 inches into the wall, breaking through the drywall. The impact was so hard the refrigerator door also popped open and stuff went flying out. I had to slam on my brakes to get it to stop moving forward even though my foot was not on the accelerator.

The vehicle initially had a windshield manufacturing defect according to Cadillac Service Center which allowed plenty of water to go inside the vehicle during heavy rain. After the vehicle was serviced weeks later I was driving and the digital dashboard when completely yellow and red. At the same time the automatic brakes activated and I almost got rear ended. They serviced the car again after being tow trucked and “couldn’t” determine the cause of the dashboard incident shown on the pictures.

The automatic collision system braking is engaging when the vehicle is in reverse and while it is raining. This occurs multiple times while trying to back the vehicle up during rain. This is dangerous for the passengers since they are abruptly thrown backwards without warning. The vehicle must be placed in "park" and then "reverse" multiple times until the collision braking stops malfunctioning.

What component or system failed or malfunctioned, and is it available for inspection upon request? Multiple components of our driver assistance software have failed, beyond what we can check in the fields above. Most recently, we have experienced two major failures. The first failure occurred when the car triggered the emergency parking brake on its own while we were driving in traffic at 30 mph. We narrowly avoided being rear ended. This is the incident I've detailed in the fields below. The second failure occurred when the adaptive cruise control failed to brake as we approached gridlock traffic. We again narrowly avoided collision on multiple fronts. We were going approximately 45 mph with roughly 2000 miles on the car. We have the service records, but the selling dealer and Cadillac engineering claim these issues are now fixed. How was your safety or the safety of others put at risk? We were well within less than a car length of collision in both of the situations described above. This car is a large SUV, it would presumably cause significant damage to cars it hit. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. They verified failures and out-of-date software in our vehicle in this last service visit. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? This vehicle has been directly inspected by Cadillac engineering through our selling dealer. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? The warning lights we experienced included the warnings that the system had engaged and "service driver assist system." There was no warning when the adaptive cruise control failed.

On September 9, 2025, while slowly turning into a parking space at approximately 7 mph, the vehicle suddenly experienced unintended acceleration. There were no warnings, alerts, or Safety Alert Seat vibrations prior to the surge. The vehicle rapidly accelerated forward, struck a parked car, went over a curb, hit a tree, and finally came to rest after colliding with the side of a building. GM has since taken possession of the vehicle for forensic analysis.

on Sept 23, 2025, I was rear ended by a driver going between 50-60 mph. I am concerned that some safety features were potentially not working at the time of the incident. I will detail the information below: Background / Original Service Issue: When I initially brought my vehicle to Titus-Will Chevrolet GMC Cadillac for service, I observed that multiple critical safety systems were nonfunctional, including, but not limited to: Forward collision alert sensor All cameras (rear, front, top down) Blind zone steering assist Lane departure warning and other associated warning sensors The dealership kept my car for two days and then informed me that a "module" needed to be ordered for repair, but stated that the vehicle was considered “drivable” and would call me when the part came in. I noticed some of the safety features had resumed working, however some were still non-functional. At no point was I told there were any potential safety risks, nor which safety systems were still not functional. I was not given any paperwork, as they were holding it until the module came in. Crash Event: On 09/23/2025 at 5:37 pm, I was involved in a crash. At the time of impact: The forward collision alert sensor did not function I received no warning of the impending collision No airbags deployed. This may have been directly related to the previously identified and unrepaired safety system issues.

The car briefly lurched forward and the car engaged an emergency brake to prevent the car from rolling into the vehicle in front of me. This incident was unpredictable and resulted in an unexpected change to the drive mode I had selected which could have lead to a collision.

I was driving at a steady 65mph on a highway when the car suddenly surged and the message "1 pedal driving deactivated. Use brakes to stop." I stopped the car with the brakes and restarted it and reactivated 1 pedal driving. Note I was NOT using regenerative braking at the time. The car surged a few miles an hour, and in a heavy traffic scenario could have easily caused a crash.

Since a recent software update, vehicle will unexpectedly give multiple error codes, and disengage “one-pedal driving” mode. This happened recently when coming to a stop at a traffic light behind another vehicle. When coming to a gradual one-pedal stop, the one pedal driving mode unexpectedly disengaged, causing me to almost hit the vehicle in front of me. This error has occurred 5-6 times in the past 3 months.

One pedal driving switched to unavailable while driving - 24 Lyriq AWD I have seen this couple of times while driving now. I keep the one-pedal driving setting on High. I suddenly get an error on Side detection unavailable and One pedal driving turned off - use manual braking. I also feel a slight surge in acceleration while this happens, but I have been able to slow down and re-engage one pedal and it seems to work after that. I am concerned that I may bump into someone in front of me if this happens again, since it has happened a couple of times now!

POWER TRAIN,ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE

1 complaint

While driving my 2024 Cadillac Lyriq in rolling traffic, the vehicle abruptly engaged the brakes without warning or cause. The braking was so forceful I initially thought I had been rear-ended. Once the braking event ended, I began to accelerate—only to discover the vehicle had shifted into reverse without any input from me. This resulted in a rear-end collision. There were no alerts or dashboard warnings to indicate the gear change. I believe this may be related to a malfunction in the automatic emergency braking system or the shift-by-wire controller. This behavior presents a serious safety hazard and must be investigated. I have filed a report with Cadillac and will be taking the vehicle to a dealership for diagnostics and data log review.

- Software failure resulted in loss of steering control, speed control, and brakes became unavailable. I was on highway car was at 65 mph and then I got a bunch of error messages mentioned below- 1) Steering assist not available 2) AWD is disabled 3) Headlamps not available 4)Service brake assist And then I was not able to brake the car, and steering became highly unresponsive. I took my foot of gas and let the car roll for 1 mile before stopping safely on shoulder, from where I called Cadillac for support (they towed the car back), since error didn't resolve after stopping or rebooting the car. I took screenshot of these errors after stopping and attached them in this email. - Yes it put safety of me, my passenger, and other vehicles at risk, loss speed and steering control you have cause me to hit any other car. - Yes problem is reported to manufacturer, car is in service. - Vehicle is with Service, since no one got hurt, we didn't involve police. - No prior message or warnings we recieved, all errors come as soon as the issues appear.

When it rains, just a steady rain, not a downpour, the vehicle slams on the brakes trying to back up. It literally took 3-4 minutes to back out of the driveway. I was also in a parking lot trying to back out and the same issue which created a significant safety hazard with other vehicles. Research online indicates this is not an isolated issue.

POWER TRAIN,ELECTRICAL SYSTEM,SERVICE BRAKES

1 complaint

While driving northbound on [XXX], south of Oklahoma City, at normal highway speed, at night, in the rain (on [XXX]), this EV lost all power to the wheels and the regenerative braking ceased to function. It appears that all flow of electrons from the batteries to the drive motors, and from the regenerative brakes to the batteries stopped. I still had dashboard lights, steering, and conventional brakes. I was able to safely coast to a stop on the highway shoulder. I set the parking brakes, put the “transmission” into “park”, and turned off the power button. I then restarted the car, and all was normal again. I continued my drive from Austin, TX, to Evergreen, CO with no additional incidents, arriving on [XXX]. This is reminiscent of the “blue screen of death” in old Microsoft desktop computers — fixed the problem by cycling the ON / OFF switch. Unfortunately, doing this when driving at 75 mph is less than ideal, and is a real potential safety problem.

PARKING BRAKE,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE

1 complaint

While driving through Wisconsin on [XXX] with Super Cruise activated in 70MPH traffic the car provided me with driver's side collision warning failure notice and then a forward collision warning failure notice, but the car continued to be operating normally. A short time later a brakes overheating warning came on while the car still seemed to be operating normally and maintaining speed. I immediately disengaged the cruise control to check out the situation and the car instantly locked on the brakes, and we could see smoke and smell the burning brakes. I pulled to car to the side of the road, and we exited the car concerned there might be a fire coming from one of the 4 smoking wheels. The rotors were red hot. We remained a safe distance from the car until the brakes stopped smoking. After it appeared safe, I reentered the car and determined the brakes (parking brakes) were fully engaged and the car would not move. We contacted OnStar for assistance and waited. After a significant time (it seemed like quite a while) I suddenly heard the sound of the parking brakes electrically releasing. Shortly after that I started and tested the car again and it would move so we slowly drove it off the busy interstate to the next exit a short distance away and continued working with OnStar to obtain a tow to a Cadillac dealership. After working with OnStar for several hours and determining that there would most likely be no tow truck coming, we decided to test drive the car around the area now that the brakes had cooled off. We ended up renting a 'safety' car that my wife would drive, and I would try to drive the car back to Minnesota to our dealer. The car operated normally for the drive home, but we did not use any cruise control just in case. It was my belief that a system communication issue told the brakes to engage and that since the Super Cruise was engage the motors just added more power to over-come the drag on the brakes until they over heated.

VISIBILITY/WIPER

1 complaint

I am writing to report an issue with the windshield durability on my 2024 Cadillac LYRIQ. Over the past three weeks, I’ve experienced three separate instances where small rocks struck the windshield while I was driving, each impact resulting in a crack or chip. In my experience with previous vehicles, similar impacts would rarely, if ever, result in such immediate damage, which raises concerns about the material or design of this particular windshield. This frequent damage has quickly become costly and frustrating. Windshields should withstand small impacts to a reasonable extent, and this does not seem to be the case here. I am also reaching out to Cadillac to address my concerns, but I wanted to report this issue to NHTSA in case other drivers are experiencing similar problems. Please let me know if there is further information I can provide. Thank you for looking into this matter.

ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL,FUEL/PROPULSION SYSTEM

1 complaint

I purchased a brand new Cadillac Lyriq on July 1, 2024, and have encountered several severe issues that compromise the safety and reliability of the vehicle: 1.Display Failure: The display frequently flickers, flashes, and sometimes completely blacks out, causing the loss of critical information such as speed, backup camera, navigation, and other vital systems. This makes the vehicle unsafe to drive, as it is impossible to monitor speed and other essential functions necessary for safe operation. 2.Battery Overheating During DC Fast Charging: The vehicle’s battery consistently overheats during DC fast charging sessions, causing the charge rate to drop significantly (from ~190 kW down to 14-20 kW). This overheating issue not only drastically extends charging times but also raises serious safety concerns, particularly during long road trips in hot weather. The vehicle has repeatedly experienced these issues, making it unreliable for long-distance travel. 3.Charger Overheating and Instability During Home AC Charging: The home AC charger provided with the vehicle becomes excessively hot while charging the Lyriq. Additionally, the charging rate fluctuates erratically between 0-3 kW, further complicating the charging process. This overheating of the charger at home raises concerns about the safety of parking or charging the vehicle in my garage, as it may pose a fire risk. These issues have been reported to my dealership, who have attempted repairs without success. The problems persist, and the vehicle remains unsafe and unreliable for my family’s needs. I am deeply concerned about the potential for these issues to lead to more severe safety incidents if not addressed promptly.

Without warning and while driving this vehicle on expressway, I've received the following notifications several times: "Brake Failure" (car brakes on its own); "Service Stability and Auto Hold"; and "High Voltage" and Battery. Brakes, speed, steering, parking systems and camera do not work properly. Car's capacity to drive vehicle safely is reduced significantly - speed to drive car is immediately reduced and is limited without warning. Car shakes passengers violently (whiplash) when it believes there are people or objects in its path when there is nothing there and does not work properly when pedestrians are around the vehicle. During the incidents both my safety and other drivers safety are at risk - I am afraid to drive this vehicle although the dealership has indicated they have corrected the errors.Vehicle purchased 23 Oct - problems began around 2300 miles and have continued thru 4200 miles.

1 complaint

While driving the 12V battery system failed as well as the high voltage charging system. The vehicle lost traction control in the rain and was slipping on the road. The forward collision detection also intermittently goes out. If you are in one pedal driving mode and using adaptive cruise control when the forward collision detection goes out it will deactivate adaptive cruise control and apply enough regenerative breaking to rapidly slow the car. If the driver does not have their foot on the accelerator when this happens and you are in traffic it could cause an accident. The vehicle is not saving any diagnostic information regarding these failures and dealerships will not work the failures without diagnostic codes.
