While driving on residential street at 30 mph, vsc, abs and trac dash lights came on and cabin alarm sounded. The brakes were not functioning. I had to use the emergency brake and evasive driving to avoid rear ending a school bus. After bringing to my mechanic I learned that the master brake cylinder had failed. The part is $3,100 from Toyota. Spending money on car parts and repair is all a part of owning a vehicle, but no car should be designed where the brakes completely stop operating because of an electrical short. It is insanely dangerous and this will cause deaths for sure, how can it not? I have researched this and it is a very common and well known issue. A lot of drivers have been very frightened by this issue, including myself.
After traveling at speeds close to 75 miles an hour. I exited highway to parking lot. Backed out and was unable to stop car from rolling. Moved car to new parking area and had to use parking brake to slow down. Shut down car check fuilds. Restarted car to loud buzzer and abs lights. Very concerned if happened on highway could have been fatal to myself and others around.
My wife was at the school zone taking our children to school, when she heard a noise and an alarm start to sound, the abs and track off lights came on and the brake pedal went to the floor, she was not able to stop the vehicle, fortunately she was on school speed zone and nothing was in front of her and the vehicle stop by it self because the low speed, she was about to enter on the freeway to take our son to other school and I can't imagine what could had happen if the brakes would failed while she was at high speed on the freeway. We been searching online about other people having the same problem and we found out that this been happening to other 4 runners owners and our biggest concerns is that this can end up taking others peoples lives, because a malfunctions in this vehicle, we took the vehicle to the dealer, and certainly exist an electrical problem and since then our vehicle has been useless in storage.
