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.

There appears to be something dangerously wrong with the transmission. I have experienced this randomly, maybe a dozen times, over the last week since I have owned the car. It takes up to two seconds for the car to respond after pressing the gas pedal. This has happened when slowing down and then having to give the car gas, again. Other times it has happened from a stop or an idling roll. There is a significant hesitation. This does not happen every time, which makes it that much more dangerous - being unpredictable.

2010 Toyota 4runner fails to accelerate intermittently when gas pedal is pressed. Has failed to respond to accelerator for a full three seconds at one point. Commonly, delayed response lasts 1-2 seconds. Took vehicle to dealership. They were unable to duplicate the problem. Service tech said this could be caused by the electronic traction control. Issue occurs regardless of traction conditions.
