Example complaints

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

“During some cases of downhill driving, the Brake system warning light will come on. I believe this issue is tied to a combination of longer and steeper downhill drives when the angle indicated in road side sinage is no less than 6%. Minimal braking ton control the decent is used. Each time this occurs, I take the nearest off ramp to pull over to a stop and turn off the engine. My visual and hand-test of each wheel/tire temperature finds in my opinion, the temps to be quite nominal. …”

“Rear emergency brake locked up only on the passenger side, causing the brakes to be ripped off the shoes and destroying the springs and hardware. This also caused the wheel bearing to lock up and it was destroyed as well. I could no longer spin the wheel freely.”

NHTSA complaint #11445557, filed 2021-12

“The rear parking brake pivot point gets stuck in the on position. After some research, this is VERY common on these vans and is going to cause wrecks or deaths. The pivot point where the parking brake connects to the rear parking brake linkage rusts and gets stuck VERY easily. My van only has 60,000 miles on it. There is no sensor in this pivot point, so when you release the parking brake, it seems like it is off—but it is not. No indication no warning.. Tire spun and van drove fine until the breaks failed. …”
