Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I started the truck after not driving for 1 day and a heavy rain storm the day prior. I attempted to drive bobtail when the brakes locked up. The traction control light came on then went back off. Then the adaptive cruise control notification came on. The regon came on then went back off. A speedometer sign with an exclamation mark came up and would not go away. After attempting to go down the road the brakes continued to lock up, would not release and caused the rear passenger tires to go bald and lose my job.”
