What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Took my truck to a body shop to have dings and a few rusted spots on it repaired. The business owner and repair person put it on the rack and after examination, informed me that it was not worth the repairs, because the frame and undercarriage was too extensive and might as such cause safety issues.
Owned since 2003, the truck has only 140,000 miles, but my mechanic advises that frame is badly rusted and is unsafe to drive. I've learned this is a common issue and that toyota has an active recall. Rear bumper has also rusted through. I need advice on how to proceed. Vehicle is parked at my residence.
The contact stated that the entire frame of the vehicle had severe corrosion. The contact observed brake fluid leaking from the front of the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 99,300.
When backing out of a parking space lower left a-arm broke (rust) and left front tire collapsed. Have learned that toyota tacoma trucks made in '90s had defective frames and there was a buy back. Shop tells me my frame is bad. Truck has only 69k miles on it.
Clutch pedal bracket on toyota t 100 went through fire wall while driving. Could not get truck in our out of gear. Looked on net and found many have had this same problem. Contacted dealer no recall and no help with pricing to repair truck. Safety concern about not being able to get vehicle out of gear!
Wires to fan connector melted the insulation just short of the connector and shorted out. Pictures of failed wiring are available.
The contact stated that the seat belt locks, but becomes loose when driving. The seat belt fails to retract when the failure occurs, but the seat belt warning indicator light illuminates. The current mileage is 105,000 and failure mileage was 100,000.
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.
