The contact owns a 2003 Toyota Tacoma. There were 14 miles on the vehicle at the time of purchase. The contact stated that the paint was chipping on the vehicle. He filed a complaint with the manufacturer and they declined any liability for the failure. The current and failure mileages were less than 36,461. The vehicle also had frame rust. Updated 09/09/09.
I have a 2003, Toyota Tacoma, v6, 4x4, trd package. I was driving down the freeway and every now and then it is like I took my foot off the gas but I didn't! if I step on it, it is fine. The problem: is throttle by wire throttle bodies on 03 and 04 Tacomas. The accelerator petal position sensor assembly has a shaft onto which the lever for the accelerator cable is mounted with some return springs. This shaft also turns the potentiometer. This lever (a plastic piece) limits the travel of the assembly, so the highest and lowest resistances of the potentiometer are not encountered in the potentiometer. The problem is that the potentiometer can also turn in the assembly, loosing its reference to the arm and lever. Then the range of resistance that is possible can be changed. If it turns too far one way, the higher resistance will be such that there is not sufficient voltage sent to the ecu to indicate that the pedal has been depressed. Conversely, there is a point at the other end of the petitioner where the full voltage is applied and the ecu sees this as a failure and closes the throttle by releasing the throttle control motor's clutch. Nothing has been to done to solve this issue with Toyota or dealership. Mechanic can not replicated problem. Suggested I replace brand new throttle body which is about $600.
After my purchase of a new 2003 Toyota Tacoma pre-runner I quickly discovered my rear chrome bumper was rusting at the area where the license plate is displayed. I took my new truck to my local Toyota dealer and was told that Toyota recognized this was a problem but there was no recall issued on the problem and that I could continually use a type of steel wool to keep up with the rust as it was happening. Unacceptable.
