What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
1 problem is the seat belts, they don't tighten back. Problem 2: the headlights are very poorly lit and there are internal microcracks, the lamps are standard. Problem 3: Cruise control sometimes does not work and does not brake when approaching a vehicle.
The front side rails of the body of the vehicle have corroded (rusted) from the inside and have perforated the exterior of the members exposing them to further damage. In my opinion, the vehicle is no longer safe to be driven without the risk of the members collapsing and possibly causing an accident.
