Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While driving on the highway I noticed a knocking sound radiating from my engine at speeds of 60 MPH it the noise increased and then the engine appeared to be failing. My gages where the rmp's reflect where not functioning either. Amongst the engine issue my power steering column is also rattling as if it is loose and steering is become difficult. It is frightening to not feel safe in your own vehicle.”
NHTSA complaint #11088909, filed 2018-04, 115,000 miles“We have had multiple issues with the car accelerating. The vehicle will not respond immediately when pressing the gas pedal. We have had the car worked on by Hyundai 12-15 different times and it continues to have the same issue time and time again. We do not feel safe in the vehicle. The last time that we had the issue was in october of this year and we have not been able to drive the vehicle since that time. Hyundai will not help us get out of the vehicle even though it has had the safety concerns. …”
NHTSA complaint #11162831, filed 2018-12, 151,000 miles“Took car in for repair of malfunctioning stop lamp switch all the same issues as in NHTSA campaign 13v113000 even though my model year was covered in recall they said my VIN was not covered I was charged a fee to diag the vehicle and for parts and labor.”
NHTSA complaint #10632117, filed 2014-09, 97,000 miles“While car is in motion, on highway or anywhere at anytime, the check brake warning light comes on display screen, with an beeping alarm, then the brakes drop to floor barely stopping the vehicle with a grudging noise. I went to the dealer, they gave me the option to replace the ABS system but was not sure of the exact problem and tried to sell me a newer car. This company already has lots of recalls and has put many people's lives in danger. This issue is happening to many other vehicles the same as mine and they are not safe for anyone.”
NHTSA complaint #11172968, filed 2019-01, 120,000 miles“My vehicle check charging system warning came upon the start up of the hybrid in the morning 12/31/2018, going to work. This was an issue on a heavy precipitous day in past. However there was not heavy rain, I turned the vehicle back off. It turned on without the warning which 1st appeared in front area and is audible. It started as I approached a stop sign. I live about 6 minutes away from work. The battery life is visible and it was not changed from mid point which has always been same. The tank had gas, no issue, and I drove it to work. …”
