We have been having trouble with my 2008 Toyota Tacoma truck with the engine revving when we first start it up. We took it to the dealer. They said that this is "normal" last week we took it in due to a safety recall notice for sudden acceleration problems that Toyota claims is due to floor mats. Dealer cut down the accelerator pedal, reprogrammed the computer control system, rotated the tires. Upon pulling out of the dealership the steering wheel vibrated (side to side) and car bucked (front to back) there were loud grinding and banging noises. Car pulled strongly to the left. I took my foot off of the accelerator. Instead of slowing, the engine suddenly revved up. Due to oncoming traffic on both sides of us, I focused on steering us out of trouble by keeping us in our lane. I did not apply brake. I had thought that without gas, the car would gradually slow down on its own. Instead of slowing the engine revved up! truck suddenly lurched 90 degrees to left, jerked steering wheel our of my hands vehicle lurched into the oncoming traffic lane, whole front passenger side tire assembly came off and headed one way and the truck went the other. We were thrown forward, down and to the right. The vehicle kept moving until we crashed into concrete entrance/exit of dealership. I put on emergency brake. Dealer says "simple human error mechanic forgot to tighten bolts on tire" I think this goes way beyond a tire problem. They messed with computer control system and the accelerator pedal. I can't see how tires cause engines to rev up. Updated 01/28/11 updated 02/07/11

Shimmy and tramping of front steering at freeway speeds (45 -70 mph) worse after hitting bumps. Truck jumped sideways one foot on turn while crossing bridge after encountering a bump this almost caused an accident. I have complained about this problem to the dealer several times, since the truck was new.

Truck has front end vibration as if tires are out of balance. Dealer has rotated and balanced tires twice and advises that this is a problem known to Toyota and that they are working on it.

Suspension is doing a loud friction sound when driving over a bump at a very slow speed, it sounds like metals are having friction one against the other, this is happening every time you drives over a bump, bigger bump louder sound. And there is no way to go fast over these bumps all of them are at school student dropping areas and security is first than everything, but is any part of the front suspension damaged because of this?
