I had an accident in this vehicle where the airbags deployed upon impact (as they were designed). However, once airbags deployed, my vehicle was filled with smoke (from the airbags) and all of my windows were covered and I couldn't see out. Panic set in as I tried to get out of the vehicle and my door would not open. After several moments I thought about the door locks, they were engaged of course. Once I realized and hit unlock, the door opened. This isn't an issue as far as parts being a defect or anything like that, but today I heard of a Texas DPS Trooper being in an accident in his Tahoe. His took a front impact as well, and the person trying to help him couldn't get him out of the vehicle. It made me wonder if his locks were engaged too, and him being more severely injured may not have thought about the door locks. This could be a potential safety risk, especially if the vehicle is on fire. What if vehicle manufacturers were able to install a safety mechanism that would automatically release the door locks if an impact was detected, or air bags were deployed? Just merely a suggestion as none of the parts on my car failed, they all did their job, but not being able to get out of your car is terrifying. I'm not sure if I am in the right place to pass on this suggestion, so if not, please advise where I might leave one. Thank you.

A/C condenser replacement. GM previously admitted problems with 2014-2017 AC condenser in certain model years of trucks and suv. The recalls should be extended to later years. I recently replaced AC condenser on 2018 employer owned Tahoe with typical crack and weld areas. Today, having same part replaced on my personally owned 2018 Chevy Tahoe. GM obviously has a defective part thousands nationwide are complaining about. The is obviously a defect GM should recall and replace at their expense.

The Trailer Brake System Service light and ding constantly go off while doing standard driving without any type of towing involved. I have never used a trailer on the vehicle; however, the ding and service light are a distraction and cannot be turned off.

Just driving down the freeway and my sunroof just shattered. We were not driving under anything for something to be thrown or fall on the sunroof and nothing was thrown up from the road.

I have a 2018 Chevrolet Tahoe. Today, while I was pulling out of the Sam's Club parking lot I heard a huge thud, the car jerked forward and completely stopped. The drive line / drive shaft had broken clean off. I'm awaiting official diagnosis from Riverton Chevrolet's service dept., but it was a very scary situation. I'm thankful that I was not rear ended or hurt. I see that welding issues are part of a NHTSA safety issue on later model Chevy Tahoe vehicles. I'm wondering if my 2018 is a victim of a similar problem. I do not drive at high speeds or go off-roading. I get my car serviced regularly. This could have been catastrophic if I'd been on the freeway. Repair invoice pending.

STEERING
8 complaints
The contact owns a 2018 Chevrolet Tahoe. The contact stated that after parking the vehicle in a parking lot and returning to start the vehicle, the “Power Steering Assist Fault” message was displayed, and the vehicle was difficult to turn to the right or the left. The contact left the vehicle in the parking lot and after returning to the vehicle later and starting the vehicle, the vehicle had regained power steering assist functionality. The vehicle was taken to an independent mechanic who diagnosed the vehicle and determined that the 12-Volt battery needed to be replaced. The contact was advised by the mechanic that due to the weak battery, the power steering assist failed to operate as designed. The vehicle was repaired. The contact stated that several weeks later the power steering assist failure recurred. The contact stated that the "Power Steering Assist Fault" message was displayed. The vehicle was taken to another independent mechanic. The vehicle had not been diagnosed or repaired. The contact researched online and related the failure to NHTSA Campaign Number: 21V455000 (Steering); however, the VIN was not included. The manufacturer was not informed of the failure. The failure mileage was approximately 84,000.

First occasion the car drove fine with no indication of an issue. Then once the car was turned off then on, the dash showed no lights or gauges and indicated that the steering assist is not working and the wheel was impossible to turn (almost like a limp mode but not driveable). Disconnected the battery to try and clear the issue and car drove home fine. Was told it could be a bad battery so replaced the battery and it worked fine for about a month. Then again with no indication did it again and this time it cleared itself after about 30 minutes. Dealer said there was a short in the negative battery ground cable and an open circuit in the rack and pinion mechanism but that the rack and pinion part was not available and they weren’t sure when it would be (probably due to excessive failures). Replaced the negative battery ground part and everything was fine for about 3 months until today when the car did the same thing again. We will have to keep looking for the unavailable part or I will basically have a $30k paper weight. Very concerned at the possibility that the steering will go out while I am driving as others have mentioned in previous posts. Seems as though something tragic will have to happen before they issue a recall of a part that appears to be a common failure.

Power steering went out with kids in the car when vehicle only had 76000 miles. There was a special coverage for 2018 models that my vin was not a part of. Had it been this wouldn't have happened to my family. I was without a vehicle for over 2 weeks since dealership had to reach out to GM to find the part. Apparently, this is big issue for other models and years which explains the part shortage. A few months prior there was a service power steering on my dash, and I couldn't turn my steering wheel. Took it to dealership and they brushed it off as computer issue. Again, I feel if my vehicle was part of the special coverage, I wouldn't have experienced this issue or had to pay over $2000 to repair it.

My wife was driving everything was working fine until a message came on the dash "steering stopped Drive with care" she was mid way in a turn to get on highway when this happened if I wasn't in vehicle to grab the wheel my wife would have ended up in a wall or worst case in the canal next to 95 with my 4 year old in the car. The vehicle is currently at a chevorlet dealer in Greenacres Florida and they say the electric steering gear has stopped working.. this seams like a very unsafe system as when it stops the steering wheel is very stiff more than a old car with no power steering. I think this needs to be investigated yesterday as someone could die from this if it hasn't happened already. As of right now I no longer feel that this is a safe vehicle for my wife to be driving

On 7/27/2023, the transmission in my 2018 Chevy Tahoe failed. There was no warning, noise or lights I dicating a problem. I was trying to excelerate after turning at a stop light. There was a slight hesitation when shifting so I let off the gas. When I tried again, it didn’t do anything and I began losing speed. I had to have the vehicle towed to the dealership. Upon their inspection the tech determined internal failure inside transmission. I was told I was 3,000 miles out of warranty.

Manufacturing problem, but not listed under recent GMC recall of April - May 2025 - 2018 Chevy Tahoe Problem: Transmission Issue - slippage
May 06, 2025
Transmission suddenly locked up while driving. Took to dealership and was advised it was a chronic issue with my vehicle. Once inspected by dealer, was advised that engine lifters also went out. My car was just out of warranty with 55k miles. Dealer did not want to honor warranty and charged me 15k in repairs. I reached out to Chevy and they provided me with some assistance by knocking off 3k. I did not get any warning lights indicating that there’s an issue with the engine or transmission. It happened suddenly. I feel that there is an engineering issue with the transmission and engine. The mechanic checked in my vehicle and said to me that this was a persistent issue with Tahoes like mines. I feel cheated by Chevrolet.

Vehicle stopped accelerating while coming up to speed from an on ramp to the interstate while traveling from Indiana to Florida. Vehicle was towed to the nearest Chevy dealership where we were told the engine had blow and would need replaced. Vehicle has been sitting on the same dealership in Florida since early July. My families lives were put at risk as we were traveling at a low rate of speed on the interstate. As well as, sitting on the side of the interstate in a remote area waiting for a tow truck and cab. The dealer has confirmed what happened via inspection. There were not warning lamps until we lost the engine.

Brake assistance on this vehicle sucks
Sep 12, 2022
When applying the brakes the SUV will pull hard to the left or at times to the right. I get a screen message that reads " trailer brake system failure". The SUV has never trailed anything. Also dont know if these are tied together but I'm also experiencing a dragging battery during this time. When the trailer brake says failure goes away the battery issue goes away. I've done some research and have found a GM service call "N192261050" which seems to indicate the same issue/concern.

As I drove the 2018 Chevy Tahoo the brakes got really hard to press and would no longer stop. I was finally able to get it to stop and moved off the road. The vehicle was towed to the AutoNation Chevrolet Mesa Dealership (6330 Superstition Springs Blvd. Mesa, AZ 85206). I was told that the vacuum pump seized causing the brake belt to break. I was told by another mechanic that there is a recall on the hydraulic vacuum pump breaking system....... As the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash. Summary: General Motors LLC (GM) is recalling certain 2015-2017 Cadillac Escalade, 2014-2018 Chevrolet Silverado, GMC Sierra, 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles. The amount of vacuum created by the vacuum pump may decrease over time.

OVER THE LAST 6 MONTHS THE BRAKE PEDAL IS HARD TO PUSH AFTER THE TRUCK SITS OVER NIGHT. THE VACUUM BLEEDS OUT INDICATING A VACUUM LEAK IN THE SYSTEM. GM AND THE DEALER SAID THIS MODEL AND YEAR NOT COVERED UNDER CURRENT RECALL.

Purchased brand new Chevy 2018 Tahoe in April 2019. Overall good car never had any issues until 02/08/23 as I was driving a got a service alert "Trailer Brake System", It was so random since we have not hauled anything for that to even become a problem. The next day 2/09/23 the car was not drivable it wouldn't turn on it kept giving me the same alert "Trailer Brake System". I called the dealership and they said it's a defect and have to take the Tahoe in for service since only they can find the defected harness and now I have to pay out of pocket for something that I did nothing wrong, something that is manufacture defect and completely unsafe to drive.

7-21-23 Unit stalled 3 times today. The last time was while driving. Check engine light on. 1-29-24 Today I was responding to an emergency backup for an officer that was fighting two subjects. The subjects were fleeing from a stolen vehicle and it was dispatched that these subjects were armed. I never made it to this call because my vehicle #10688 would not accelerate past 23mph and then shut off leaving me stranded in the roadway. While waiting for a tow truck I was able to get the vehicle started again and was able to drive at only 36mph to try to get to the scene and assist the officer. I ultimately was able to make it to the police station. I wrote up the vehicle and left the keys in the training building.

The Body Control Module does not work. A new BCM was installed in my car in April 2025. Since then I am having multiple issues, but the safety related issue is with the trailer braking system. It is available for inspection upon request. The dealership is unwilling to try another BCM without it costing me $600 for labor. If I am unable to use my brakes, then I put myself and others on the road at risk. The problem started with a Tire Monitor System. I was told I needed a BCM to fix the problem so the car would not throw codes. Now, I am being told the problems with the brakes are not comiing from the BCM. THERE WAS NOTHING WRONG WITH MY car until I took it to this dealership for a new key faub and a tire pressure monitor error. The Body Control Module in a 2018 Chevy Tahoe Premier does play a role in controlling the sunroof. More specifically, the sunroof system is supplied power through a fuse located in the driver-side fuse box which is connected to the BCM. The sunroof switches communicate with the BCM via a serial data circuit, and the BCM then commands the sunroof to open or close. Therefore, the BCM acts a central hub in the electrical system of the vehicle and communicates with the sunroof control module to operate it. I learned this from two other dealerships. One dealership in West Virginia and another dealership in Texas told me this information about the BCM controlling the sunroof and many other electrical parts of the 2018 Chevy Tahoe Premier. To make it simple, the BCM was replaced. The vehicle is now having serious issues. I consider an unintended activation of the braking on the wheel which causes the vehicle to pull to one side puts me at risk of a crash. Is this yet another failed sensor or part due to the negligence of the service department at Smith Buick when replacing the BCM and programming a key faub?

My vehicle started announcing service trailer brake system when i purchased my vehicle about 5k miles in i took it to the dealer they couldn't find anything wrong now that message started to get worse not only is it a safety concern due to the annoying beeping. Sound on the dashboard indicating something is wrong. It makes me take my eyes off the road it Constantly distracts me every time it goes off. Also, feel every time that message appears. My truck slows down. As well, a safety concern when pulling a trailer. The brake system could fail on the trailer due to trailer brake assist malfunctioning.

Crash: 1
Injuries: 1
My vehicle recently has had 2 issues that I have taken in to the Service Shop for 3 times and the problem has not been fixed. My most concerning issue is my brakes. My brakes are doing the exact problem indicated in this article: https://www.consumerreports.org/car-recalls-defects/gm-recalls-suvs-and-pickups-for-braking-issue/ When the brakes malfunction, I feel a vibrating brake pedal, feels like my vehicle is not going to stop on time, I hear a ticking noise from the engine and my Brake Assist Service light comes on. The issue continues until I can pull over and restart the vehicle. It is a very uneasy feeling having to drive a vehicle that you do not feel safe in. I called 800 Chevrolet's Customer Service number provided in the article and they are unaware of the recall mentioned in this article. I do not know where to go from here. I just want my vehicle fixed and to feel safe. My 2nd issue is regarding my Adaptive Cruise Control. I've had it in the shop 3 times for this also and they did replace a part but that did not fix this issue. I will be driving down the highway or interstate and out of the blue my alarm starts dinging, the seat vibrates, the cruise control gets kicked off and I get an alert on my dash stating that the Adaptive Cruise Control was disabled. Each time it has happened to me there is nothing around but it immediately starts reducing my speed. If someone were behind me it could cause a crash because of the unexpected speed limit reduction. When you go in to look at recalls on 2018 Chevrolet Tahoes it shoes that there is 3 of them that have been issued, yet my VIN is not included in any of them? What can I do from here? I've called Chevrolet's 800 # and they created a "High Urgency Case" but I have not heard back. Attached are my copies of service records and vehicle summary showing there has never been recalls on my VIN #.

No service was completed. 15,000 Miles - Asked service dept. at dealership to check again for rattling noise coming from engine. Service indicated fluttering heard was exhaust pulsing through the manifold. No service was completed. 21,000 Miles- Service Dept at dealership provided multi point inspection and given clear inspection. No service was completed even though I stated there was still engine noises. 24,000- Asked service dept. at dealership to check hard shifting from transmission and poor performance. In addition, mentioned the noises again. No service was completed, service stated it was due to colder temperatures. 25,000- Asked service dept. at dealership to check hard shifting from transmission and poor performance. In addition, mentioned the noises again. Engine cooler lines were replaced. Scanned and verified clutch learn values all normal. Activated TCC and disabled TCC and found normal operation. No service completed. Now, after warranty has expired, service at dealership is telling me my camshaft and lifters need to be replaced, struts are leaking, transmission needs attention and should be flushed, and that I should NOT be driving my vehicle due to safety concerns. Although, I had taken the vehicle in multiple times during warranty period with complaints about these very items, no service was ever completed to correct them. Since then, I have read multiple articles documenting GM issues with L87 6.2L engines and transmissions. I'm filing a formal complaint with GM, as these issues should have been communicated to consumers or fixed through recalls.

The repeated failure of the fuel pumps, despite replacement three times, poses a significant safety concern as the vehicle may not start immediately, potentially leading to issues while on the road. This delay in starting could result in the vehicle not running properly, potentially shutting off unexpectedly, which poses a danger to the safety of the driver and others on the road. Additionally, the uncertainty surrounding the effects of using E85 fuel, despite the vehicle being sold as flex fuel, raises concerns about the long-term viability of the motor and overall vehicle performance. It's imperative to address this issue promptly to ensure the safety of all road users and preserve the longevity of the vehicle's components.

Caliper became stuck which produced smoke coming from tire. Had the caliper replaced. Then months later my forward collision system activated because a car in front of me stopped abruptly. After the car automatically braked to slow my car down, the brake never released and became stuck and the ABS light came on. Replace the abs sensor and two days later the brake engaged on its own while doing 60 mph on the highway. Now whenever the hill assist, collision warning, or anything else is activated, the brake engages and gets stuck. In addition, at times on the highway my brake will engage on its own.

A lifter collapsed, which in turn damaged the lobes of a piston, which then damaged the camshaft...generating a repair bill of $7,100 per the dealer. The vehicle only has 69,200 miles on it. When the lifter failed, the car shuddered at stops, lost some power and made a noticeable clanking noise. When pulling out from stops, or into traffic, the car hesitated somewhat before accelerating. This creates a very dangerous situation. Also, if more lifters or the camshaft seized up at higher speeds, a driver could experience a potentially fatal situation from an uncontrollable vehicle or a fire. Research shows that Chevy/GM knew about the lifter problem on 5.3 ltr engines with their AFM system for years and sold them anyway. They apparently have never solved the problem, and it still exists today. Several class action lawsuits have been lodged against them for the lifter failure problem. Aside from the serious potential safety issues, an expensive vehicle like my Tahoe should not be expected to incur a $7,100 repair bill when it's only 4 years old and has less then 70,000 miles on it. That's ridiculous. My wife and I are both retired. We will be tapping our retirement account to pay for this shoddy Chevy product and will worry that it just might occur again, after the fix. From a safety standpoint, a stall, loss of power, or engine seizure at speed will tax our quick response reflexes. The known lifter problem is a legitimate safety situation and needs to be addressed before someone is seriously injured or killed...if they haven't already. Thank you for listening.

SEAT BELTS
1 complaint
1- the second row center Seat Belt Receptacle stopped locking so failed, this happened while using the vehicle. 2- the seatbelt receptacle stopped latching while using the car in Seattle, I had to drive with someone in that seat unbuckled because all other seats were being used. 3- the receptacle can not be repaired, needs to be replaced; 4- I have contacted the manufacturer to have them fix this but they will not do it without compensation. 5- no warning. the vehicle is not old and in very good condition. I drive with my family in the car daily but rarely need to use the middle seat. I feel this is a defective latch due to the limited use and age of vehicle. I am concerned that the other seatbelts will also break without warning and Think that GM needs to be aware of a possibility.

VEHICLE SPEED CONTROL
1 complaint
THE BRAKE PEDAL IS TOO CLOSE TO THE DRIVER IN RELATION TO THE GAS PEDAL. THE DISTANCE OF EACH PEDAL CANNOT BE ADJUSTED INDEPENDENTLY. A DRIVER'S FOOT CAN BE TRAPPED IN BETWEEN THE TWO PEDALS BECAUSE OF THE GAP. IN A FATAL SITUATION, IT TAKES LONGER FOR THE RIGHT FOOT TO MOVE FROM THE GAS PEDAL TO THE BRAKE PEDAL SINCE THE RIGHT FOOT CANNOT JUST MOVE LATERALLY TO THE LEFT, BUT IT NEEDS TO GO AROUND.
