2017 Toyota 4RUNNER Brakes Problems

“While driving at full speed on the freeway, another vehicle stopped suddenly in front of me. My brake pedal was soft and went down almost to the floor. Rapid pulsing of brakes, as would be expected with the ABS (antilock brake system), did not occur. I pulled around to the shoulder and barely managed to stop in time to avoid a collision, which was quite a frightening experience. I have had a few similar incidents since then, and have noticed that the brake pedal is a bit soft until pumping the pedal a few times. …”

“Approaching an intersection on city streets I experienced temporary brake failure. When applying the brakes to slow down the pedal went all the way to the floor and did not slow down the vehicle. After rolling through the intersection without incident I pumped the brake pedal a few times which returned the brakes to an operational status. This has happened 3 times in 2 days. Other Toyota 4RUNNER owners have also reported the same or similar issues in the last 12months.”

“When you apply the brakes with full force while driving; the brakes lock up for a short period of time on one side of the vehicle, causing the vehicle to swerve uncontrollably. This is extremely dangerous vehicle when the brakes are applied with hard force at speeds at around 35 MPH or higher. Luckily I am a very experienced driver and car handler and was able to react quick enough to control the vehicle one time when I had to apply the brakes hard at highway speeds when a car swerved in front of me suddenly. …”

“I pulled up to a stop light and applied the brakes. I stopped but while I was sitting with the brakes applied, my 4RUNNER started rolling forward. I had to push the brake peddle to the floor to a point I could barely reach to get it to stop again. I took it to the dealership and they agreed the brakes were not acting right. They could see on the computer that something was wrong as well. They said I would need a new master cylinder on the 4RUNNER. The vehicle is only 2 1/2 months old with 2500 miles. …”

“Vehicle bought new 8/2017. Has approx. 7,000mles. This is the 3rd or 4th similar incident but the most severe. Driving on I-95, approx. 60 mpr, today, when I applied the brakes they seemed to lock and although my first thought was that the car also accelerated it may have been only my expectation of slowing down and that wasn't happening. The brake pedal only seemed to compress about 2-3 . Luckily I was able to pull over and the car did stop. I continued on without incident but like I said this was the 3rd or 4th time and the most severe.”
