2001 Toyota 4Runner Owner Comments

problem #4

May 192016


  • 135,000 miles


We were told today that our 2001` Toyota 4-runner has frame rot that is inconsistent with the age of the vehicle and the condition of all the other parts on it. Frame rot that constitutes a danger to our safety when driving it. The repair technicians advised us to determine if it was part of Toyota's frame rot recall with the Tacoma and other vehicles because the frame rot rust was consistent with the pattern of damage they had seen on other recalled vehicles. When we looked up our 4-runner in the recall information, supposedly Toyota hasn't included our truck in the recall. We were advised by our auto repair specialist that the recall covered damage in trucks that were the same age and overall condition, so it's not as though the rest of the truck is eaten up by rust and we just happened to complain about the frame rot. The frame rot pattern found on our 4-runner is consistent with the frame rot found on recalled Toyota trucks and inconsistent with the rest of the vehicle's stability. Because this is such a dangerous situation, and because the frame rot is a known problem, it's important for other consumers to know that regardless of their care of the vehicle, the frame may rot at a rate that is inconsistent with the rest of the vehicle, and it costs lots of money to repair. 4-runner owners should have their vehicles checked for premature frame rot, and Toyota should do the right thing and fix the frame rot in the 4-runners. Just thought that after we were made aware, so should other consumers and safety organizations.

With engine running and while stopped at intersection, brake pedal is released, then accelerator pedal is pressed, vehicle begins moving, all check engine lights turn on, car stalls in the middle of the intersection (with oncoming traffic). This situation has occurred 3 times and may have lead to at least one fender bender where the vehicle in question was hit from behind because following car thought that my car was accelerating through the intersection. After stalling, all 3 check engine lights may or may not stay on. After putting car in neutral and restarting engine, car accelerates on runs normally until next stalling event. Since January 2010, I have been to the Toyota dealer service department 4 times. I have had 2 gas caps replaced, oxygen meter replace, break/accelerator pedal checked, charcoal canister replaced, new battery, and several oil changes. The problem still persists. This upcoming weekend they said they will change the throttle body assembly.
