“ABS module stopped working and the ABS module light is on. Car automatically brakes by its self sometimes or locks up at stop lights creating dangerous driving situations”
NHTSA complaint #11556945, filed 2023-11, 157,000 miles“About a year and half ago, a lot of my engine trouble lights turned on while driving. It was sleeting at that time when the lights turned on and they're still on today. I paid to have the Hyundai dealer to check it out soon after the trouble lights first turned on. They diagnosed the problem as a faulty HECU. I would have had them replace this, but they estimated it would cost about $3800 to fix. …”
