Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Twice I have had to replace the rear axel seals due to them leaking. When I had the rear axel seals replaced I have also had to replace the rear brakes due to the oil getting on the brakes. I discovered where the seals were all but gone when I had my tires replaced. I was told that I did not have any rear brakes due to so much oil leaking on the brakes. I live in the mountains of nc and I would have lost my brakes if I was hauling anything down the mountains.”
