general problems of the 2018 Volvo XC90

My Volvo's Xc90 brakes have failed twice. At around 95,000 miles, my brakes stopped working, and then I had them repair it. They charged me close to $3,500, which they said they were able to cover under warranty, and I only had to pay the deductible, which I don't remember. In less than nine months, at about 104,000 miles, the same problem persists. Both times I was driving the car, by god's grace and luckily, I was under 10 mph. I literally parked and started driving after that, and I realized the brakes weren't working again. I'm just thankful to the almighty that I was not at 55 or 60 mph on a freeway when the brake stopped working.

The first incidence occurred around December 20, 2023. I was traveling south on I-85 in north carolina about an hour north of charlotte. I pulled into a rest area and, upon pressing the brake pedal, heard a bit of a hissing noise and suddenly the brake pedal was extremely hard and the car was very difficult to bring to a stop. I did an online search for what might be wrong and discovered it was likely a brake booster failure. I drove the car onto charlotte, carefully and with extreme difficulty, and took it to the swedish connection, a local Volvo specialist. They confirm the diagnosis and replaced the brake booster. Last night, April 14, 2025, I drove the car down to pickens south carolina for work. When I got in to return to charlotte late at night, I turned the ignition, put the car in reverse, and, with my foot on the brake and waiting to back out of the parking space, I heard that hissing noise again. Sure enough, the brake booster had evidently failed again. I drove the car back to charlotte, mostly on interstate 85, and the electronic braking seemed to work ok under cruise control maintaining speed and distance between other cars in traffic. Of course, driving the vehicle on local roads, through stoplights, and turns was extremely difficult and dangerous. I have returned the car to the same mechanic that repaired the last brake booster. I will be reporting this to Volvo as well, as this is a serious safety issue and defect with my vehicle. The mechanic has confirmed that this has happened in other Volvo xc 90s. The vehicle has not been inspected by the manufacturer.

When driving the vehicle at a speed of 15-40 mph, the SUV is activating the crash imminent braking "city crash avoidance" without anything in the path of the vehicle. This action is locking up the vehicle and seat belts lock up squeeze my wife unexpectedly. Dealor cannot find anything wrong when running diagnostics and will not replace the modules that control this feature without them showing bad. This has happended on the same road on multiple occasions.

Brakes continously squeak. The dealer has inspected the break system twice and made one attempted repair. One week later the brakes are backing to squeaking. I have owned the vehicle less than 90 days, I've had issues with the brakes for more than half that time. The center display computer screens freezes constantly, but recently freezes and will not restart until after the car is stopped and restarted.
