“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”

They stated no codes or issues were shown on their end and retur…”

Structure 4

“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 d…”

“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.”
NHTSA complaint #11620012, 2024

“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. The vehicle was taken to a dealer, and the contact was informed that the failure was a known issue. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 1,500.”

“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.”

Back Over Prevention 2

“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.”

Visibility/Wiper 1

“Bluelink remote start with climate control is defective. When initiated, the vehicle starts but the climate control system comes on in the OFF state and does not apply the saved preset, including front and rear defroster settings. This defeats the intended pre-conditioning function in winter conditions, where a remote-activated defroster is a meaningful visibility/safety feature. The defect has persisted since early December 2025 and is documented widely on Hyundai's owner forums and on Reddit across multiple model lines. A recent Hyundai-issued app update removed the standalone remote stop b…”
