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 #2

  • miles


Was in parking lot of store. Started engine and put in gear and vehicle shot forward and it seemed as if I had no control of it sideswiping another vehicle and headed for another vehicle that I was about to broadside when I was able to stop my vehicle. Was able to get vehicle home which was a short distance away but am now terrified to drive it. Notified insurance company. I called dealership where vehicle was purchased but unable to speak to anyone. Left message but no one has returned my call.

Tacoma 4WD 6-cyl

Hard start with 2004 Toyota Tacoma. This problem began the day I drove it off the lot. Sometimes the vehicle starts right up and other times it takes 3-5 attempts at starting. This nonconformity usually happens after its been driven and sits for 1-2 hours. The vehicle has been brought in for this intermittent starting problem 5 times. With 870 miles on the vehicle I brought it in and Toyota said the spark plugs were fouled and changed them. The problem continued to occur 2-3 times per week. With 1500 miles we brought it in again and Toyota said the problem was the electro magnetic current interfering with the injector circuit. They removed the ground wire cable out of the wire harness and said the engine started just fine. The problem continued to occur. The third time I brought it in with 9087 miles. They performed a tsb EG042-04 fpn-8122-04052, 0P EG4016. The problem continued to occur. The fourth time I brought it in with 9901 miles the technician could not duplicate the problem and said everything was in specifications. The problem continued to occur. The fifth time I brought it in it had 11.700 miles. Toyota replaced the ube sub-assmbly E. the engine still has problems starting.
