Owner Complaints (4)
While driving in a snow storm, your brake system suddenly failed—you saw a low braking power warning and ABS malfunction alert with loud beeping, and your brakes stopped responding. You had to swerve onto the shoulder to avoid hitting another vehicle. A complete brake failure is a serious safety issue that requires immediate inspection of your brake system and ABS components.

Your brake pedal went to the floor without warning while slowly driving into your garage, causing the vehicle to hit a bench. After pumping the brakes and waiting, they appeared to work normally again, with no fluid leaks visible. Despite being under warranty and investigated by the dealer and Toyota corporate (including data recorder review), the problem was never diagnosed or repaired over nearly two months.

Your brake pads and rotors are wearing out unusually quickly — you've needed replacements three times in just 45,000 miles despite only commuting short distances on regular streets. You mentioned the brakes felt off from the moment you bought the vehicle, but the dealership says they've inspected the system and found nothing wrong. The brake system may have an underlying issue causing premature wear, such as a caliper problem, brake fluid contamination, or a stuck component.

On May 27, 2021 The brakes failed on my brand new 2021 Toyota TRD Off-Road Premium 4Runner. I attempted to brake at a stop light, the brake pedal went to the floor and the car did not stop. Luckily no accident occurred and I was able to drive it home (4 miles). No warning lights or messages appeared at all before, during or after the incident. This occurred between 3-4 pm in Custer, SD on Main Street during clear weather. The vehicle was hauled to Toyota dealer in Rapid City, SD the next morning, May 28th. They could not duplicate the issue, brakes appeared to work fine. They found no fluid leaks and no computer trouble codes. Dealer says they can't diagnose and fix it unless they can replicate the issue. I asked how brakes can completely fail and then work fine again - they don't know. After this brake failure I have found several other 4Runner owners who have experienced this same failure, under similar conditions and speeds. Other owners have also submitted incident reports to NHTSA.
