Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

problem #4

Vehicle loses power unexpectedly and is inconsistent. Has happened before to me and many, many times by others with the same vehicle. A poorly designed/engineered accelerator pedal position sensor appears to be the issue. Toyota has been notified by me multiple times but refuses to acknowledge this serious flaw in their vehicle. Most recently, I was nearly rear ended when on the freeway, the vehicle suddenly lost power. Fortunately the driver behind me was conscious and was able to make an emergency maneuver to the other lane. Someone will die from these problems! this has been well documented by many at I ask that the nthsa please investigate and do something about this. It appears many of us, including myself, have submitted complaints on this issue and nothing has been done. One may argue that this is an 8 year old vehicle so no reason to investigate. This issue has been brought to your's and Toyota's attention since 2005. It needs to be investigated! please.

On June 11,2010 I was changing the anti freeze in my 2003 Toyota Tacoma.the vehicle was in park and running to warm engine to open thermostat to get more coolant from the lower block. Well I decide to boost the engine speed by manually moving the my surprise my truck lurched back before coming to a stop I check the shifter it was still in park.but a further exam the vehicle stuck in reverse and will not go into any forward gear. I M' going to check to see if the linkage needs adjustment everybody I talk with said it was not suppose to move unless the brake was applied first.

Vehicle has a history of problems that the dealer cannot determine the causes. Vehicle does not properly shift into gear, has a rough idle, and a knocking noise in the engine. Dealer could not duplicate the problems because they were intermittent.

Tacoma 6-cyl

  • Automatic transmission
  • 5,000 miles
After approx. Putting 5,000 miles on my Tacoma 2003 double cab, I started noticing when normally bringing the vehicle to a complete stop, there is a cluncking sound from the rear end. The harder you stop the vehicle the worse it gets. It's like getting slightly rearended by another vehicle. If it doesn't make this cluncking feeling and sound as you come to a stop, it will do it once you let off of the brake pedal to idle/roll forward to advance at a traffic light, stop sign, etc. This appears to be getting worse as I continue to drive the vehicle which now has 24,000 miles on it. I took it to ron carter auto world and the service department tells me that Toyota is aware of this and considered it normal. If this is normal why don't other vehicles do this? it gets annoying looking into the rear view mirror every time this happens thinking that you've be rearended by another vehicle.
