Air bags
55 reports18 crashes1 fire
“Air Bag light stays on and cannot pass stare inspection without repair. NHSTA site has 54 reports of this issue and dealer cannot figure out how to repair. What can be done?”
Structure
30 reports4 crashes
“I took my car to the mechanic for a “once over” before driving from New Jersey to North Carolina. This car has only 41,000 original miles on it as we bought it new in 2005. Upon inspection, the mechanic came back with certain repairs that are needed due to age; but he was extremely concerned about a severe safety issue that the subframe had rotted out and needed to be replaced. This is a known corrosion issue with other years of manufacture for this model. There was a class action suit for this specific issue for 1999 to 2004 Sonatas. The subframe threatens to collapse from rust at any time and is an extreme hazard to the driver, passengers, and others on the road. There was absolutely no warning of this issue prior to this inspection, making it even more dangerous as it affects many drivers who are unaware of the issue.”
Suspension
26 reports1 crash
“My car's engine cradle, cross member or subframe is rusted out and the OEM replacement for my VIN number won't fit it correctly I'm getting really upset because this could be dangerous for me and my two young kids. I've already paid the mechanic $600 for the replacement part when it really only costs $450 at the most and the two he has ordered before have both been either too big and it says that it is the correct replacement part. What is going on?!!! If something isn't fixed soon and something happens to me or my kids there is going to be a lawsuit.”
Electrical system
19 reports2 crashes1 fire
“COMPLAINT INVOLVES PROBLEMS WITH THE ELECTRICAL SYSTEM. I HAVE BEEN TO AT LEAST 4 DIFFERENT PLACES TO ATTEMPT GET THIS DIAGNOSED- THE PROBLEM HAS BEEN GOING ON OVER 5 MONTHS. CAR HAS BEEN EXCELLENT UNTIL THE PAST FEW MONTHS. ENGINE IS FINE. WHAT HAPPENS IS THAT WHEN YOU DRIVE THE VEHICLE THERE IS SOME KIND OF SHORT IN THE ELECTRICAL SYSTEM AND THE CAR TURNS OFF. NO WARMING. WHEN YOU ARE DRIVING AT NIGHT- AND THE PROBLEM HAPPENS THE CAR GOES COMPLETELY DARK. SOMETIMES YOU CAN SORT OF GLIDE TO THE SIDE OF THE ROAD. SOMETIMES THE SHORT HAPPENS AND THEN WHATEVER IS NOT WORKING WILL RECONNECT AND THE CAR WILL NOT TOTALLY SHUT OFF. IT IS VERY DISTURBING AND FRIGHTENING. SOMETIMES MY CAR COMPLETELY DIES IN TRAFFIC- IT MIGHT BE DEAD FOR 20 OR SO MINUTES AND THEN WILL ALL OF SUDDEN RESTART AND I CAN MAKE IT HOME. I HAVE BEEN TO MY REGULAR MECHANIC WHO HAS TAKEN CARE OF THIS CAR FOR YEARS HE WAS UNABLE TO DIAGNOSE IT. TOOK TO A HYUNDAI GARAGE/ DEALERSHIP HAVE BEEN THERE 3 TIMES- THEY ARE UNABLE TO DIAGNOSE THE PROBLEM. THIS WEEK TOOK IT TO ANOTHER GARAGE THEY HAVE BEEN UNABLE TO DIAGNOSE THIS. I LOVE MY CAR BUT FEEL VERY UNSAFE. I NO LONGER DRIVE ON THE INTERSTATE…”
