Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“This is a complaint, there was not an accident. There is a clunking noise from the rear suspension area. I have had the rear struts replaced and one bushing on the right side. I have had the vehicle checked by the dealer and four independent shops. The dealer says they cannot find anything wrong. The independent shops hear the noise but can't locate where it is coming from. On the internet there are many references referring to the issue. I am reluctant to travel a distance not knowing the cause of the noise. I have written to Hyundai. …”
NHTSA complaint #10621652, filed 2014-08, 61,991 miles“We own a 2004 Hyundai Sonata (109,000 miles) we had a front end collision with significant damage. Me and my wife suffered minor injuries and the airbags did not deploy. We found out on the internet that there are frequent complaints if this failure around the nation and also in many Hyundai models across multiple years. We are filing the complaint since the error is critical and seems to be systemic in Hyundai vehicles. We do not know if NHTSA handles cars that are over 100,000 miles but we felt a complaint was warranted since the consequence of the error is so extreme. …”
NHTSA complaint #10669275, filed 2014-12, 109,000 miles“Sub frame on front passenger rusted and corroded. Caused damange to cv axle on same side. Caused alignment issues on front end. Causes tires to wear quickly, within a week. Anti theft system locks the car while driving and causes alarm to sound while driving and must open other doors and stop driving to stop the alarm from going off, headlights and dash lights and tail lights come on when brake is pressed and go off when brake is released but this problem only happens when headlights are not in use”
NHTSA complaint #11185120, filed 2019-03, 207,000 miles“My 2004 sonata which was manufactured 05/07/04. has front frame corrosion exactly like the 089 safety recall that hyundia issued already for 1998-2003. My car was manufactured a few months later and they are denying the repair because it doesn’t fall in their production dates.”
NHTSA complaint #11650911, filed 2025-03“The front subframe has a hole in it it rusted for some reason and upon research there was a recall on this particular issue but now there isn’t one. I went to two dealerships and they informed me that Hyundai had recalls on this issue that’s why I’m confused on why when I search by my VIN there isn’t any open recalls. Just because they isn’t any open recalls on this doesn’t mean that people aren’t still experiencing this issue.”
