2025 Volvo XC90 Brakes Problems

I am writing to report a serious safety concern related to a recent over-the-air software update for my 2025 Volvo XC90. On March 10, 2026, I was prompted to install a software update and scheduled it to complete overnight. The following morning, the vehicle interface indicated that the update had been successfully completed. Additionally, during a routine service visit on March 12, 2026, dealership personnel also believed the update had been properly installed. However, on March 15, 2026, while driving, I experienced a critical and dangerous failure: my brakes became unresponsive, and I was unable to stop the vehicle using the brake pedal. Multiple warning lights appeared simultaneously. Fortunately, I was near my home and was able to safely bring the vehicle to a stop by coasting through nearby streets. This situation could have resulted in a catastrophic accident had it occurred on a highway or in heavy traffic, particularly as my daughter was in the vehicle at the time. The vehicle was subsequently towed to the dealership. I was informed that during the initial installation attempt, the battery voltage dropped below the required level, causing the update to pause. Critically, I received no notification that the update had failed or was incomplete, and the vehicle interface continued to indicate that the update had been successfully installed. Upon inspection on March 16, 2026, the dealership determined that the software update resumed and completed installation on March 15—while I was actively operating the vehicle. At that time, the vehicle lost communication with its electronic systems, resulting in the loss of braking functionality. This sequence of events raises a significant safety concern. A software update that can pause due to low battery voltage and later resume without any notification—particularly while the vehicle is in operation—creates an unacceptable risk to drivers, passengers, and the public.

The contact owns a 2025 Volvo XC90. The contact stated that while driving downhill at 15 MPH, while depressing the brake pedal, the vehicle would not come to a complete stop as intended. No warning light illuminated. The contact stated that he drove up a hill in order to come to a stop. The vehicle was towed to a local independent mechanic, where it was left for further diagnosis. The local dealer was not contacted. The air bags were deployed. No injuries were sustained, and no medical attention was sought. A police report was not filed. The vehicle was not repaired. In addition, the contact related to the failure to an NHTSA Campaign Number: 25V282000 (Back Over Prevention) that was repaired prior to the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 5,000.

Complete brake failure. Vehicle would no slow at all. Brake failure warning on dash. Now multitude of warnings.
