The manufacturer was made aware of the failure. The approximate failure mileage was 101,000.
3 weeks ago we had the transmission module fail on our vehicle while it was being driven. According to Volvo forums, this is a multi-model year, multi vehicle issue for those with sunroofs. Accrding to the dealer in our case, the seal failed, and water runs into the compartment where the transmission module is located, causing it to fail. We had it happen twice, and both times on the highway, with the engine running ragged causing it ot accelerate and then quickly decelerate. There were 3 warnings that popped up-"Gear lever locked," "transmission acceleration performance reduced," and "Parking Brake unaavialble." It happened twice and and was towed to the dealer both times, as it was not drivable-once the vehicle was parked it would no longer move out of park. …

VIN: [redacted] Make/Model/Year: 2018 Volvo XC90 Mileage at time of each incident (58,385 / 58,480 / 68,261) Approximate dates of each incident Vehicle has experienced recurring brake system failures. First, a seized rear brake caliper (Sept 2025) requiring caliper/rotor/pad replacement. Four days later, brake pedal became stiff and hard to depress; brake booster diagnosed as internally failed and replaced. Approximately 9 months and 9,800 miles later, vehicle experienced complete loss of braking ability while driving - brake pedal would not stop the vehicle, driver had to use the parking brake to stop, vehicle was towed to dealer. All repairs performed at authorized Volvo dealer. This is a repeat failure of the same brake system after a documented repair.
Engine & cooling
While actively driving into an intersection, driving on the street and or stopped at a light or at a stop the vehicle will shut off, the lights on the dashboard will sometimes be on, other times go completely black, a notification pops up on the dashboard saying "engine not in P". There is no way I'm aware of to re create this action. My children's safety as well as mine has been put at significant risk and in harms way as well as others due to the severity and nature of this unexpected risk while driving on the freeway, through intersections and in general driving through traffic and busy streets. I've had multiple close calls of almost being hit when the car stopped while I'm driving with my children. The problem has yet to be reproduced by the dealer at this time however we have photos and video of it's ongoing safety concern. …
The engine coolant bleeder hose in my 2018 Volvo XC90 cracked in the middle of my journey causing a severe coolant leak. This happened in August of 2024 while driving and the engine coolant suddenly started showed warning with low level and the engine started overheating. The vehicle would not accelerate past 20 mph, and the temperature warning light flashed continuously, creating a safety hazard in traffic. The Volvo dealership diagnosed the issue and confirmed that the coolant bleeder on the supercharger is broken and leaking. They replaced the bleeder hose and vacuum fill system. I believe similar issues happened to the 2016 models and a recall was issued for the coolant bleeder hose (part # 32249907-0) to be replaced by Volvo. This has not been recalled for the 2018 models, making it an expensive replacement for me. …
