What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Axle seals on 3 out of 4 hubs failed and leaked grease all over the brakes causing 80 percent brake failure. I had to buy all new seals and brake shoes. This was with less than 3k miles on unit.
What to check before buying
- Service brakes. Pedal feel, ABS operation, leaks, discs and hoses.
