Body problems of the 2024 Hyundai Sonata

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.

Driver side bumper does not sit flush with driver side fender. It popped out between top edge of bumper and fender. . . Many compliments on social media. . . . . Hyundai needs to fix these cars. The bumper retention.

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.

Driver side bumper does not sit flush along driver side fender; pops out along top edge between bumper and fender. Many reports of this issue from factory, including all trims and all colors. A TSB needs to be issued for these vehicles to fix the bumper retention. Many owners with this issue.

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.
