1 Service Brakes problem

Failure Date: 09/18/2019

Approximately 7:45 am on 9/18/19, my son while coming home from work, had an accident. I was not with him at the time. When he showed up at home after the incident, he explained how he was unable to stop the vehicle before it collided with the vehicle in front. He articulated that when he applied the brakes, it was as if he vehicle sped up. Remembering years back during a presidential campaign, this was an issue with some other Toyota's. The verdict was the place mats interfered with the pedals. When I released the vehicle from the tow lot, I checked and this was not the case as the floor mat was secure. I have driven Toyota vehicles since the early ninety's and have owned five. Checking for recalls as a result of this I found multiple incidents on record. The panic braking system surprised me the first time I experienced it. Low speeds (25mph or less) I thought a true asset but because of the quick stopping, higher speeds worried me. Never needed the panic brake but once. Some how, I believe the communication (ai) with the panic, anti-lock, braking system, and the way it communicates speed and conditions is the culprit. The insurance company is in possession of the 4runner and I still have the title. Please contact me to advise how to proceed. They seem anxious to get the title but I am animate to know if conditions or vehicle defects played a part in the accident. When I mentioned this to the insurance company, they avoided the issue.

2 Service Brakes problem

Failure Date: 05/01/2014

I purchased a 2012 Toyota tacoma from cfl Toyota. The VIN is 5tfju4gnxcx019880. 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 Toyotas, the engine is used to "gear down" and assist in breaking. 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.

The contact owns a 2012 Toyota 4runner.

The vehicle was taken to the dealer, who was unable to diagnose the failure.

4 Service Brakes problem

Failure Date: 07/30/2012

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.

5 Service Brakes problem

Failure Date: 07/27/2012

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.
