The brakes of the vehicle slip. When you are on the freeway and you need to stop for accidents and you brake the vehicle slips and almost wants to role over. When the vehicle comes to complete stop after a few seconds it moves forward almost 6 inches. There could be several reasons why this could happen with ABS systems, could be hydraulics, could be the sensors, it could be pulsation. Diagnosis for this requires precision not a simple test drive. The dealership says its normal and that's how limited slip differential works but it slips often and on even roads. The dealership wants me to duplicate the problem for them and I won't want to get on the highway at freeway speeds to show them how the brakes slip. Its a safety concern. I called the manufacturer since I am still under warranty and they say they wont do anything. Bottom line the brakes are not safe and I am worried about a roll over or a serious accident.

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).

Applied brakes firmly at yellow light and vehicle nose dived, brakes locked and vehicle stated to skid. Let up on pedal and applied brakes again and vehicle stopped without further drama. Did not feel the antilock brake system pulse the pedal or hear the system growl. Second time this has happened under same circumstances. Plenty of room to stop before the light changed from yellow to red. Light brake application always required to avoid vehicle nose diving. Light application of brakes doesn't slow it very well. Brakes seem to be very touchy. Last vehicle was a Toyota highlander which had no brake problems.

While stopped at a red light on level ground, vehicle began to creep forward with foot still pressed firmly on brake. Unless brake is pressed almost to the floor, the vehicle tends to creep forward while stopped and in gear. Paid more attention to brakes over the next couple days and also noticed that the vehicle will start rolling when shifted into gear with foot on the brake if brake is not pressed almost all the way to the floor. The problem seems to be more defined when it is hot outside (>95 degrees). Took vehicle to dealership and technician noted that "soft brake feel" is a characteristic of this vehicle. No repair was accomplished or offered.
