Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“The Traction Control System commonly malfunctions while making turns on curving road sections. I will lose power through turns as the TCS light blinks on my dashboard and makes a beeping sound. On some occasions the brakes will automatically engage in the tire that the car perceives as experiencing slippage. This problem is continuously worsening and commonly endangers me and my passengers, as the car engages brakes or cuts power to the engine at unexpected and in opportune times.”

NHTSA complaint #11659970, filed 2025-05

“I had the control arms replaced, then one of the bolts came out after a few thousand miles. I had that bolt replaced and the problem started happening intermittently after that. Everything will be functioning fine and then the speed of my vehicle is inhibited and it is hard to accelerate. It is very difficult to get from 40 MPH up to 50 MPH. On slight curves, not always, it will beep and the slip indicator light comes on and will apply the brakes on what feels like one side. This has happened at 35-60 MPH. The slip indicator will beep sometimes until I decrease my speed to under 25 MPH. …”

NHTSA complaint #11426725, filed 2021-07

“While driving at approximately 30 to 50 MPH, on dry and smooth pavement, usually going on or off ramp to the left, the skid control engaged and warning sound came on, automatic brake takes over and start braking the van uncontrollably, pulling the vehicle to the right and nearly causing accidents.”
