My car when shut off and restart will show the wrong speed. I am not the only person who has been dealing with this and you can look up 2024 hyundai sonata n line speedometer and a reddit post will come up with other people dealing with this. Hyundai is not willing to deal with this even after proving it was off

The DAW (Driver Attention Warning) system is obtrusive and a distraction to safe driving. The alert makes an audible "Beep" and the drivers display lights up with a warning to "Take a break". This alert will continue every 5 minutes if on a winding road until the car is stopped and the engine is turned off. When operating the vehicle in a safe manner keeping my eyes on the road and having the beeping and warning lights distracting me is quite the opposite of its intended purpose. In previous year models this could be turned off by the owner. This is not so with the 2024, 2025 models. This is not isolated to this vehicle but a search of the internet will find many frustrated owners all voicing their concerns. A safety alert system should not become a safety hazard. The dealer has no solution. The alert system cannot be turned off or it's sensitivity adjusted. The manufacturer has so far not responded to my complaints.

My vehicles speedometer is always reading 1-4 mph faster than the actual speed I am driving at. For example cars speedometer would read 67 but only actually going 63. I’ve noticed it’s always 1mph off but whenever driving the car and turning it off to say get gas and turn right back on, the speedometer will begging reading 3-4 mph faster until leaving the car off for a few hours then it would go back to only reading 1mph faster again.

I along with other people on various websites have noted that the 2024 N-Line has something wrong with the speedometer. I first noticed is on the waze that is was different. It must have something to do with the internal GPS of the car. I tested it alongside another car and it is indeed off. It happens after driving the car into a place that isn't obvious on the map. I brought the car to the dealership and they weren't able to help. I know there is a slight allowance for speedometer being off, but this is way off. For example, it can show one is going 25, while really going 20. This causes me to have to look at Waze to get proper speed. This is a real issue and if search hyundai sonate N-line speedometer being off, you can find other people talking about this issue. Please really look into this as this is a major concern that falls outside the allowed difference in speedomter and actual speed

The speedometer is not always accurate. About 75-80% of the time at highway speeds the speedometer shows 4mph higher than WAZE. While I understand this could be a WAZE issue itself, I have completed the following test. I was driving at highway speed with my wife following me in her vehicle. My speedometer is 4MPH faster than WAZE in my car, WAZE in her car and her speedometer. My WAZE, her WAZE and her speedometer all matched exactly. This is not a 1 time thing, it happens way more often than not.

STRUCTURE

I’m reporting a serious safety issue with my 2024 Hyundai Sonata. After a routine service at Koons Hyundai of Woodbridge in late February, the under-engine splash shield detached and dragged under the vehicle while I was driving on the highway. Upon inspection, it was clear that the splash shield was not secured with any screws or clips — it was either improperly installed during service or never fastened at all. This caused the shield to flap violently at high speeds before tearing off entirely. It posed a serious hazard to me and other drivers on the road. When I brought the issue to the dealership, they refused responsibility, falsely claimed it was caused by scratches (despite no such damage before the failure), and told me and my wife that we are no longer welcome for service. A part like this should never fall off a new vehicle, especially after a recent service. This could have caused a major accident if it hit another vehicle or interfered with my driving. I am requesting NHTSA to review this case for possible service negligence or manufacturing defect, and ensure future safety.

The front and rear bumpers of the 2024 Hyundai Sonata have an issue with the bumper brackets. The defective bumper brackets are causing many people's front and rear bumpers to pop out. While these have mostly been 1/8th inch popping off so far, my concern is this may become a bigger hazard as these cars age. Facebook groups with Hyundai Sonata owners have discussed this being a common issue. Those who have had their dealers replace the bumpers/bumper brackets still have recurring issues.

ELECTRICAL SYSTEM

3 complaints

I was sold a 2024 Hyundai Sonata SEL and while driving on the road multiple times the car completely shut off. By this all lights inside AND outside the car turned off (Headlights, interior lights and all) car was still rolling and I pulled over each time as all systems rebooted. It claimed that all seatbelts were off with the warning sign. Had to unbuckle and buckle all seatbelts for this warning to go away. Since the car completely shut off this put other drivers, my passengers, and myself at danger due to visibility. Luckily there was no traffic at the time but this keeps happening and it is worrying me.

This has happened three or four times now while I have been driving. While driving, my electrical system will "black out"/"power down"/"shut off." Everything on my dashboard turns off/goes black. My lights turn off. It is like my car shuts down for 2-4 seconds, then turns back on and I can continue to drive. There is no warning, sound, or anything. My car will just abruptly shut off. It is random too. There is no pattern that could help me determine what could be potentially causing this issue. It just happened again last night, while I was on the highway going about 70 mph. This could not only hurt me, but other people on the road. What if the next time my car powers down for a longer period of time? Who is to say what could potentially happen? I intend on scheduling an appointment with a Hyundai dealership to take a look at this issue. But I figured that because this has happened three or four times now, it will probably happen again, and other people are probably having this issue too. It could be a potential defect with the electrical system.

My car tends to jerk very hard two to three times on cold start up and I’ve read that the previous years have had this issue. They are still the same mechanically so I do not know why my year does not have a recall for it

FORWARD COLLISION AVOIDANCE

2 complaints

I have not had accident in vehicle. There is a driver attention warning feature in the 2024-2025 Hyaundai vehicles that can not be turned off. They were able to be turned off in previous models. Because of the over sensitivity of the feature it creates a distraction while driving. It triggers activation after 10 minutes of driving and goes off if you’re swerving or wearing sunglasses, etc. a number of reasons. However, while I have been driving perfectly fine, it continues to go off and beep every 5 or so minutes. No swerving. Both hands on wheel. The feature isn’t a bad idea but needs to be less sensitive and able to be turned off. Going off so consistently creates a distraction to me while driving. I could see there potentially being many lawsuits regarding this due to accidents. I have spoken to multiple Hyaundai dealerships and they all say there is nothing they can do.

VEHICLE SPEED CONTROL

2 complaints

The vehicle speedometer is occasionally 5mph off. When I first get into the vehicle after it’s been sitting for a while and drive around, the speedometer works perfectly. If I shut the vehicle off while getting gas, running an errand or something similar that involves the vehicle sitting for a semi-short period of time, the speedometer will be 5mph off when driving. I initially detected this issue be noticing that my speedometer was different from the speed posted on a GPS based speedometer on my phone, who’s speed exactly matched those road side speed measuring signs found on the highway, but both of those measuring devices differed from my vehicles speedometer. I brought my vehicle into my local Hyundai dealership who verified the problem exists, but mentioned that this was a software issue which needs to be corrected my Hyundai Corporate. I contacted Hyundai Corporate at the number provided to my by the dealership, and was essentially told that there is nothing they are willing to do to fix the issue.

As I’m driving 75 MPH, my car slows down and on the dash board it reads 20 MPH LIMIT. I’m on the Expressway and, prayerfully, by putting on my HAZARD BLINKERS, I pull over, wherever it’s safe, turn car off, restart the car and then it’s fine. PLEASE HELP BECAUSE THIS IS A LIFE THREATENING SITUATION! SCARED This has occurred SEVERAL TIMES.. Approximately 1 month ago I took it into SERVICE DEPARTMENT (kept 1 week and never slowed down on them. Again, once the car is turned off, it drives fine. How can I turn off this 20 mph hour limit on dashboard. Any advice or help you can give me to put me at ease, is CRITICAL! Thank You in Advance.

BACK OVER PREVENTION,FORWARD COLLISION AVOIDANCE

1 complaint

In morning dew/foggy winshield, the systems will disable easily. You get pop ups such as: Inattentive Driving Disabled, Camera Obscured. And forward collision warning disabled, camera obscured. I’ve had many vehicles in the past and the safety systems never disable this easily over slight fog or slight morning dew. Even with a lot of fog on the winshield my other cars are still fine. I also have a 2023 Elantra that has NEVER done this before. It seems to be an issue in Hyundais new driver assistance systems in 2024+ vehicles.

STEERING,ELECTRICAL SYSTEM,LANE DEPARTURE

1 complaint

Complaint ID: 11667442 Vehicle: 2024 Hyundai Sonata Mileage: 20,000 (approx.). Update Summary: This update concerns the persistent, severe Electronic Stability Control (ESC) steering malfunction previously reported. Current Status of Issue: The ESC steering defect remains unresolved. The vehicle was taken to an authorized Hyundai dealership on July 15, 2025, for re-diagnosis. The technician reported being unable to find any fault, despite the clear, dangerous, and recurring symptoms of steering control loss and near-collisions. The vehicle is still unsafe to operate due to this unaddressed safety hazard. Manufacturer's Response: During this recent service visit, Hyundai continued to refuse to provide a loaner vehicle for the diagnostic and repair period. This refusal places the driver at extreme risk due to the necessity of driving a vehicle with a known, uncorrected safety defect that has already failed a previous recall repair (performed June 6, 2025, RO 41686321 ). Impact: The vehicle's safety is severely compromised. The persistent ESC defect, combined with the manufacturer's inability to diagnose/repair it and refusal to provide safe alternative transportation, necessitates immediate intervention.

After a dealer-installed software update on my 2024 Hyundai Sonata sel awd, the car began jerking during acceleration and shifting. This happens at low and moderate speeds and creates an unsafe hesitation, especially in traffic. This issue did not exist before the update. I believe the software update affected the transmission or engine control calibration. The dealership has not resolved the issue, and it poses a safety concern. Please investigate whether this is linked to a faulty update affecting other Sonata vehicles.

STEERING,LANE DEPARTURE,BACK OVER PREVENTION

1 complaint

Vehicle: 2024 Hyundai Sonata. Current Mileage: 17,804 Primary Safety Defect: Electronic Stability Control (ESC) Steering Malfunction The vehicle's ESC system has a severe, intermittent malfunction causing unpredictable loss of steering control. This defect creates an extreme safety hazard. Occurrences include the vehicle veering unexpectedly towards highway medians and losing steering precision during turns and roundabouts, leading to multiple near-collision incidents. The vehicle is currently considered unsafe to operate. Relevant History: This ESC concern was subject to a manufacturer recall. An authorized Hyundai dealership performed the "ESC SOFTWARE LOGIC UPDATE (24-01-065H-1)" on June 6, 2025. Despite this specific recall repair, the severe ESC steering issue has persisted and recurred multiple times since that date, indicating a failure of the repair to permanently resolve the safety defect. Secondary Safety Defect: Inaudible Parking Collision Assistance The vehicle's parking collision assistance system is non-functional. Its audible warnings are inaudible and have never worked as designed since vehicle acquisition. This eliminates a critical safety feature intended to prevent low-speed parking collisions. Finally, The combination of a critical, recurring ESC steering defect, unaddressed by a recall repair, and a continuously inaudible parking collision assistance system, renders this vehicle highly unsafe to drive. Immediate investigation and permanent resolution are required.

Vehicle suddenly accelerated after pulling out of store parking lot at low speed into side street behind vehicle stopped at light (less than a car length in front) while pressing hard on brake. Vehicle lurched forward incrementally during the braking process, but vehicle kept accelerating causing vehicle to hit stopped vehicle numerous times before vehicle engine was finally turned off. Driver of both vehicles could have been seriously hurt. Vehicle was driven home after this incident without incident but has only been driven out of garage and onto and off towing truck. Car has not been inspected except for damage to vehicle and is currently awaiting insurance rep inspection at vehicle repair facility. Once damage is repaired car will be towed to dealership for inspection. Because of the short distance vehicle traveled no warning lamps/messages were noted.

I have gone 3 times to dealer because speedometer was off. They confirmed that the speedometer was off but they couldn't do anything about it. They told me that for this car, there is no VSS and the speedometer gets the speed from the navigation system. The navigation system is obviously glitching which is causing this. I am not the only person experiencing this. This has to be taken care of and taken seriously

I purchased this vehicle brand new off of the lot February 2024. Since then, I have had two incidents where in the middle of driving my vehicle has completely shut off. The first experience, I was driving 50+ mph. First my headlights went out, my engine shut off, my dashboard shut off, and I was cruising without power or control over my vehicle for about 5 seconds before everything turned back on. I took my car to the dealership where they “could not confirm concern” after driving around for 15 miles trying to recreate the issue. They stated no codes or issues were shown on their end and returned the car to me. 6 months later during late October, my car did the same thing. I was driving 40+ mph and my car shut off in the middle of me driving. I contacted my dealership to inform them it happened again. They told me they did not have any available appointments to bring my car in. Out of frustration I did not bring it in until a few weeks ago for a regular check up. I gave them the exact date and time that my vehicle shut off and they again could not find the issue that caused the car to turn off. I was informed by a Hyundai representative that he anticipates this issue getting worse as it happened twice in the first year of owning it. That when it happens again to get my car towed by Hyundai roadside assistance and straight to the dealership. As stated, I lose complete control of the vehicle. Luckily both instances I have been on a straight road but I have concerns that this could happen at the wrong time leaving my injured.

EXTERIOR LIGHTING

1 complaint

The automatic high beams feature seems to work through the camera by the rearview mirror. But the issue is when this camera is blocked, all of the safety systems that use the camera will be disabled as they normally will be since the camera cannot see, but the automatic high beams function will still stay on, the indicator light for it will be green meaning that the system is operating normally. As a result of this, the automatic high beam system keeps the high beams on at ALL times because it thinks that it is dark enough because it doesn’t see any light through the camera. This could potentially increase the risk of a crash because the driver may not realize that the high beams are NOT turning off when approaching another vehicle or when a vehicle is coming the opposite direction, which can blind other drivers on the road. This needs a recall to resolve this problem.

VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE

1 complaint

Hello, thanks for reviewing. I recently bought a brand new Hyundai (VIN provided) and the speedometer intermittently is inaccurate. Maybe 50% of the time, which I would argue is less safe since I can’t reliably tell what my speed is. When it is an issue, it’s worse the faster I drive. It breaks the 10% threshold I’ve read about around 30mph, where it will say 26mph. I brought it to the Hyundai dealership and they claimed they couldn’t replicate the issue so they won’t fix it - but it’s intermittent and I have picture / video proof from multiple dates. I used various speed sources to be sure. I found some Hyundai forums online where many others have the same issue. The speedometer is an important safety feature, not to mention other dependent features, like cruise control. Happy to provide proof by request.

When driving early in the morning while it was still dark outside, the car had what seemed to have been a sudden loss of electrical power. The audio for the radio cut off, then the screen for the radio and speedometer went blank, and the headlights also went out. This all lasted for a couple seconds when this happened and then everything came back on fine. I normally would think that this is a defective alternator which it probably is and would be covered under warranty, but after researching this problem I found out that it is a common issue with the 2024 Sonata. I feel that this warrants a safety recall which I seriously doubt will happen but it needs to. If it causes problems with headlights shutting off at night then this is a safety issue. Who knows what will happen if the headlights shut off on you at night and you couldn’t see where you were going because of it?
