4Runner 6-cyl

  • 9,000 miles
Just as I put my new Toyota 4-runner in reverse in a crowded parking lot, the engine races wildly. Fortunately my foot was firmly on the brake, and I was able to get it back into "park" - whereupon the engine raced even more wildly, until I turned off the ignition. I checked to make sure that nothing was against the accelerator pedal - and there wasn't... I checked to make sure the accelerator pedal was in its correct position and working freely - and it was. So I restarted the car, it seemed fine, and drove home - and a little bit yesterday (Monday) morning - the day after the incident. All was fine... but, but, this was a very crowded parking lot where the incident took place - literally hundreds of people - including children - walking around, and many hundreds of other cars and trucks nearby... I am a life-long Toyota owner - and this will not change this. But, clearly this "uncontrolled acceleration" problem with Toyota's of late, still exists and must be corrected immediately!!!

  • Automatic transmission
  • 9,300 miles
Purchased vehicle new and the 5 speed automatic transmission operated smoothly. Around 9,300 miles the transmission started shifting gears harshly. The harshness is intermittent but happening more frequently. Also, while at highway speeds going downhill, the rpms bounce everywhere from 1500 rpms to 3000 rpms. Its almost as if the transmission is confused and doesn't know what gear to choose anymore. I also feel as if the brakes aren't releasing. When sitting at a red light going down hill, once I release my foot off the brake and before I accelerate, while coasting, I feel a "thud" in the rear end after about two rotations of the wheels. I drive in bumper-to-bumper traffic daily in pittsburgh and this shifting is awful - by far the worst transmission in a vehicle I have ever owned. I mentioned this issue during my last service visit at the Toyota dealership and they said a technical service bulletin had not been issued yet. This needs addressed asap. This can't be the way Toyota intended for this vehicle to operate - especially since it didn't always operate this way.

  • 6,015 miles
Sudden rapid acceleration, entering a parking spot, both feet on brakes, still acceleration, put in neutral then park, still acceleration, had to back up, was in a bad position, never touched the gas thru this whole incident. Relined vehicle, still acceleration, put in park and turned it off. Toyota has had it since, 9-2-2011, today is 9-7-2011. What are my options. I pick up my grand kids all the time let alone on the road shopping, errands, etc. The floor mats were not the problem.
