My 2004 Toyota Tacoma was part of the frame replacement back in the fall of 2018 when bobby rahal Toyota in mechanicsburg, PA has by truck for over 6 months while they replaced my frame. it has been determined that my rear differential is rusted and is now to the point of needing replaced. for over the last year I have tried working with bobby rahal to come to and understanding on having this repaired due to the fact that my mechanic believes that this rust is in fact the same issue as the frame and should have been replaced when the frame was. all they will tell me is that the recall is closed and there is nothing they can do. very disappointed in the fact that this was handled when it should have been. now I am stuck trying to figure out how to pay for this myself. I have taken very good care of my truck for over 21 years and there is no reason for me to have to pay out of pocket for something that they should have taken care of during the recall. I don't have a lift to check the underneath of my truck, I trust when there is a recall that the dealership will do its job and fix everything safely and not put an unsafe vehicle back on the road and wait until a vehicle rusts completely through. bobby rahal was also inspecting the truck at this time so they knew the rear differential was rusted. my current mechanic said the rear differential has been rusted since the time they replaced the frame and and has been for many years. it is irresponsible for bobby rahal Toyota to have not replaced the rear differential axel knowing it was rusted and unsafe. .
Vehicle has 113,000 miles on it but is undriveable because frame is rusted through.
Problem with the electronic throttle control on acceleration, the throttle drops off like I let my foot off the pedal, the dealer replaced the throttle body per customer request (me) and it fixed the problem, only to happen again several months later, this happened one time again, a total of 2 new throttle bodys were replaced, now a few years later it failed again trying to pass a car and I almost caused an accident because the throttle failed.
Both rear axel seals leak gear oil onto and into the rear brake drums which substantially reduce the effectiveness of the rear brakes. This condition began around the 60,000 mile mark and will continue indefinitely until the gear lube is all drained off, which then will most certainly cause severe power train damage.
On several occassions my truck has completely lost power. A few times it happened while pulling into traffic resulting in me almost being hung out in a busy intersection. When I push the gas pedal, it starts to move forward, then suddenly loses power. I beleive the problem is somewhere in the throttle body. I also get some hesitation when lightly hitting the accelator at highway speeds.
After driving approximately 10 miles in a heavy, wet snow, shifter on automatic transmission could not be moved past reverse into park. Parking brake could not be pulled. Blockage of both components felt quite solid. Because vehicle could not be put into park, ignition could not be turned off and key removed. Vehicle could not have been left on a slope without a chock block. After snow fell out/melted all systems returned to normal operation.
Extremly loud lifters(valve noise).
My 2004 Toyota Tacoma double cab prerunner v6 sr5 has 18,000miles and has had the following problem for a while. I did not notice it until about 2 months after I had purchased the vehicle. Which tells me that the problem could be a progressive issue. The truck continues to show an increase in the problem. Problem description: when driving the Tacoma down the road the Tacoma drives fine. But when approaching an intersection where the vehicle is brought to a complete stop is when the following occurs. The vehicle will shift to the rear and a jerk sound is heard and felt. When releasing the brake on the vehicle you will feel and hear another more intense jerk. When you press on the throttle pedal to move forward from an intersection the vehicle displays yet another jerk. All of these feels as if it is coming from the rear. I took the truck to the dealership for it's regular maintence and questioned the service advisor about this issue. I was told in a very "I don't have time for you manner" it's a Tacoma it will always do that. I can't nor will I accept that answer.
