2021 Volvo XC90 Brakes Problems

Driving on a 45 mph road and brakes felt squishy, like air was going out of them. It was slow to stop and had to pump then stomp to get it to stop before crashing. Was fortunate to not hit anything. Pulled into gas station and had it towed to Volvo. There were no warning lights or other indication of problem- the brakes just failed. Volvo said the vacuum pump failed which pushed oil into the brake booster causing it to fail. The car has 74,000 miles and has been serviced regularly.

The contact owns a 2021 Volvo XC90. The contact stated that upon starting the vehicle and shifting to drive(D), the vehicle failed to respond unless the brake pedal had been released for 2-3 seconds. Additionally, the contact stated that upon starting the vehicle and releasing the brake pedal to reverse out of the driveway, the vehicle rolled back at a faster speed, and the vehicle failed to respond as intended upon depression of the brake pedal. The contact noticed a pattern with the brakes malfunction. The contact stated that the brake pedal required to be depressed 2-3 seconds after the first depression for the brakes to operate as intended. The contact stated that he was a master mechanic and had concluded that the failure was considered a safety issue because the vehicle was only designed with electronic braking, which left the driver with no manual option for braking. The contact stated that the failure had only occurred upon starting the vehicle. The contact related the failure to NHTSA Campaign Number: 25V392000 (Service Brakes, Hydraulic, Service Brakes); however, the VIN was not included. The vehicle was taken to the dealer, where it was diagnosed that the brakes had failed and Software Update Number: 3.5.14 was needed. The vehicle was not repaired. The manufacturer was informed of the failure, and it was confirmed that the repair was not covered under the recall or under warranty. The failure mileage was approximately 78,500.

The brakes did not work when the automatic emergency braking turned on. When I pressed the brakes all the way down, the brakes didn’t respond because it was still in automatic mode. I was able to swerve into the next lane to not hit the vehicle in front of me. The automatic emergency braking also turned on when I was reversing from a parked location when there was a vehicle waiting to park behind me and my vehicle stoped and didn’t come off of brake/park mode. I had to turn my vehicle on and off again to get it to move again. I have taken my vehicle in twice for shaking. My back rotors were replaced 2 weeks ago but my vehicle still shakes. This car only has around 21,000 miles to have so many issues already with rotors and shaking.

My Xc90 is shuttering at interstate speeds as well as below. When I purchased, they had to machine the rotors and said they balanced the front tires. It did not help much. The brakes shake less. I'm sure the entire rotors are warped. All this with 12k miles on the vehicle.
