What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Just recently found that front end support under radiator is rusted along with motor mounts. I have had this truck since 1997 new, leased it for 3 years then bought it out right. While under lease agreement it was serviced by dealer. I have not received any "recalls what so ever " on this truck.
While having the vehicle serviced for an unrelated issue, the contact was informed that the middle portion of the frame was beginning to rust. The vehicle was not repaired and there were no prior warnings of the failure. The current and failure mileages were 120,000. Updated 09/16-10 updated 9/20/10.
The contact stated that the under carriage and the rear brake lines were severely rusted. The vehicle was taken to a local repair facility. It was not disclosed if the vehicle was repaired. The mechanic stated that the failure was similar to the tundra model vehicles. The vin was not available.
1995 toyota t100 4x4 sr5, fuel line leak do to rust where attach to frame rail, rust front stabilizer bar broke away from lower control arm.
My 1997 toyota t100 p/u, locks up the rear brakes when accelerating then when sudden stopping is needed the rear brakes go full force and front brakes assist little to none. I suspect faulty weight sensor at rear axle. Already replaced master brake cylinder.
Front seat belts don't retract. Shoulder belt will loosen up and not stay snug against your body. Is this safe? If I get into an accident there is enough slack to where I can hit the dash. The law says I have to wear them. My state inspection says they have to retract.
