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.

2012 Toyota 4Runner Owner Comments

problem #1

4Runner 6-cyl

  • 43,686 miles


I purchased a 2012 Toyota Tacoma from cfl Toyota. The VIN is [xxx]at the first maintenance, I reported instances of "unintended acceleration." The cfl Toyota mechanic and, later the Toyota of orlando customer representative reported that the event is related to the fact that for Toyota, the engine is used to "gear down" and assist in braking. I have experienced unintended acceleration about 6 times in the two years that I have owned the truck. On 1-may-2014, at the sandlake road entrance to lowes hardware near john young parkway in orlando fl, while stopped in line to enter a highway, my Toyota "lurched" (unintended acceleration) despite that fact that my foot was on the brake. I caused damage to my car and the car in front of me. I had previously twice reported this phenomena to two Toyota dealers. No injuries were reported at the scene. However, the driver of the car which was struck is seeking medical evaluation. I was cited for careless driving information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
