Got into my car, pulled out of a parking spot and approached a stop sign. The brakes suddenly became extremely mushy and the brake peddle went all the way to the floor. I didn't notice an issue when I pulled out of the parking spot. I was unable to continue driving as the brakes were not usable. I had the car towed to the dealer and they indicated the brake booster and vacuum pump failed due to "normal wear and tear". The vehicle was purchased at, and always maintained at our local Volvo dealer. Luckily no accident occurred.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list.
