NHTSA Complaint #11519890 — 2022 TOYOTA 4RUNNER

Suddenly had difficult time stopping the vehicle without "pumping" the brakes. Brake pedal went to the floor, and car would not hold stopped. There were no warning lamps during the 400 miles of driving from western NY to Michigan for a Holiday with family. Had this happened as I was waiting in line on the downhill side of the Blue Water Bridge in Michigan, it would have been quite difficult to keep in line, not touching the car in front of us. We felt lucky to have discovered the problem while going to run an errand later. We saw no external leaks to the brake system (no fluid leaking) while trying to investigate what could be happening. The problem was reported to me as a leak in the brake master cylinder which was replaced under warranty at a Toyota dealer in Grand Blanc MI. It took two weeks to get the vehicle repaired (which presented other challenges to us to deal with, as we were only visiting Michigan at the time). The vehicle had 12,600 miles on it at the time that the brakes stopped holding.
