“ABS and Traction Control light on . This cancels out cruise control also. Vehicle was repaired at 23562 miles and is out again at 32000 miles. I have been on dealers waiting list for over a month. The part used for the repair must have been defective also. W11aiting time for the repair is entirely too long. Antilock brakes are a safety concern and should be quickly fixed.”

“The ABS, traction control, cruise control and 4x4 no longer function. It started intermittently and now is constant. The vehicle is available for inspection. After a hard stop the abs won’t engage and I lost traction of the truck. There are two warning lamps that are on at all times (abs and traction control). It has been ongoing for almost 1 year and 10,000 miles or so.”

Should you keep driving it?

This page can't tell you that. 0 of 287 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
