2024 Hyundai Sonata owner complaints

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

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.

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.

The contact owns a 2024 Hyundai Sonata. The contact stated while driving at an undisclosed speed and attempting to complete a left turn, the Forward Collision Avoidance system abruptly activated, applying Automatic Emergency Braking, bringing the vehicle to a complete stop. The vehicle returned to normal functionality, but the failure became a regular occurrence only while attempting to complete a left turn. The Forward Collision Avoidance warning light was illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 60.

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

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

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.

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

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 th

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.

The contact owns a 2024 Hyundai Sonata. The contact stated while cleaning the vehicle, he became aware that the front bumper had detached. The contact stated that the rear bumper had also detached.

Front left bumper panel needs to be clipped down/manufactured better. Keeps/stays popped out. Pushing it in does not work. Multiple other 2024 Sonata drivers having similar issues

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

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 is
