2024 HYUNDAI SONATA Complaints

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?

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.

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.

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 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.

Fractured windshield from rock strike. Not Hyundai responsiblity. 2 1/2 feet from mirror thru driver view. ISSUE IS: Safelite does not have aftermarket glass. Car is 5 months old. Hyundai says they have zero replacement glass in United States. I can order ($1500), and wait appx 2-3 months. It is illegal both in CA where I reside and federally to drive with fractured windshield. How is it that auto manufacturers are able to not keep safety items reasonably in stock? Covid is long over, I’m tired of hearing “supply chain” excuse. A brief online review shows Kia/Hyundai has had windscreen issues ongoing for years. I’m not even certain that all of my mirror resident safety features are working properly.
