I am reporting a serious and ongoing safety defect involving my 2024 Volvo XC90. The vehicle has experienced intermittent unintended acceleration, intermittent loss of safety and alert systems, and false obstacle detection that triggers unexpected braking or steering input. These events occur randomly and without warning, and are not tied to a specific driver, key, driving condition, or user behavior. At times, the vehicle accelerates on its own without driver input. At other times, the vehicle detects objects that are not present, causing the car to suddenly stop while reversing or swerve to avoid perceived obstacles that are not actually in the roadway. These events occur unpredictably and create a risk of collision with surrounding vehicles, pedestrians, or objects. During these occurrences, safety systems and alerts may become unavailable or inoperable, leaving the driver without audible or visual warnings. Audio alerts and system feedback have also stopped functioning during these events, further increasing the safety risk. The vehicle has been brought in for service approximately 8–9 times for various concerns, including these safety issues. Despite repeated service visits, the problems remain unresolved. Restarting the vehicle sometimes restores functionality, but the defects continue to recur unpredictably. This vehicle is used to transport young children, and these failures present a significant risk of serious injury or death. The unpredictability of the unintended acceleration, false braking/steering, and loss of safety systems makes the vehicle unsafe to operate. I am submitting this complaint due to concern for my family’s safety and the safety of others on the road, and because the manufacturer has not resolved the defect after repeated attempts. These issues have occurred since we received the car in September 2024

My 2024 Volvo XC90 has experienced complete battery and electrical failure three times in approximately ten months. The failure pattern is identical each time. The battery discharges fully with no prior warning. A jump start restores power briefly, but the vehicle does not hold a charge and shuts down again, so it must be towed. The battery has been replaced three separate times by authorized Volvo retailers and the failure keeps recurring, which indicates the underlying cause has not been identified. Component: Electrical system, specifically a suspected parasitic current draw causing complete discharge of the 12V battery. The vehicle is available for inspection on request. Safety risk: The vehicle becomes completely inoperable without warning and has stranded me three times, requiring towing on each occasion. There is no advance indication that the battery is failing. Because the failure is sudden and unpredictable, the vehicle cannot be relied on to start in an emergency or to remain operable, and I have no confidence that a failure will not occur at a time or place that puts occupants at risk. Confirmed by dealer: Yes. Each failure was confirmed by an authorized Volvo dealer, which replaced the battery each time. Repairing dealers include Independence Volvo and University Volvo. The failures occurred in approximately October 2025, approximately March or April 2026, and [date of current failure]. The vehicle is currently at [dealer] for the third occurrence. Inspection by manufacturer or others: Volvo Car USA corporate has not inspected the vehicle. No police or insurance inspection. To my knowledge no dealer has performed or documented a parasitic draw test to locate the source of the discharge. Warning lamps or symptoms: None. There were no warning lamps, dashboard messages, or symptoms of any kind before any of the three failures. The vehicle operated normally and then would not start. Total days out of service: at least 15 days across the three times

Vehicle was stopped at a stop light with brake pedal pressed. Car started rolling with brake pedal pushed and repeatedly pushing the brake pedal did nothing! Car jerked three times and responded to pressing the park button. Once in park, I noticed that all warning lights came including brake warnings but the car would not turn off and it was stuck in park. Car would not come out of park but the radio and hazards worked. Police responded and advised not to take my foot off the brake until the tow truck got there. Initially, the tow truck driver could not put the car in drive or neutral or turn off vehicle. Tow truck driver was able to turn off the car and get it started again. Brakes should not just stop working in the middle of traffic in a 2 year old car with only 17k miles on it. Reporting because it appears this is a repeated Volvo issue. Per the Volvo app, all software downloads were updated and there was no error message before this happened.

COMPONENT / SYSTEM: Sunroof drainage system — left front sunroof drain hose and sunroof tub. The vehicle and the component are available for inspection on request. WHAT HAPPENED: On or about July 6, 2026 I observed water entering the passenger compartment at the right rear interior quarter trim panel, visible on opening the tailgate. I reported it to Volvo Car USA Customer Care by telephone the same day. On July 29, 2026, while I was driving on a highway, water dripped from the overhead panel above the rearview mirror, surrounding the interior lights, onto me. The same day I found water again at the right rear quarter trim panel and, on removing the cargo floor panel, standing water in the spare wheel well with wet carpet, carpet backing and insulation. The vehicle was at an authorized Volvo dealer from July 31 to August 13, 2026. On September 13, 2026, during heavy rain, water again entered from the overhead panel above the rearview mirror — the same location. HOW SAFETY WAS PUT AT RISK: Water entered the passenger compartment and fell onto the driver while the vehicle was being operated at highway speed, which was a distraction. Water has also accumulated in the cargo area, where the battery and fuse box compartments are located, creating a risk to electrical components. Wet carpet, padding and insulation remain a mold concern. REPRODUCED OR CONFIRMED BY A DEALER: Yes. Under repair order 403698 at an authorized Volvo dealer, the technician water tested the sunroof drains and stated on the dealership's video inspection that "the one on the left front is draining pretty slow," that it "has a slow flow through the hose that goes through the sunroof tub," and that when he poured water into the driver's side drain hose "it was overflowing a little bit into the tub where it's not supposed to go." The written repair order records only: "CLEAN SUNROOF DRAINS AND RE-WATER TEST SUNROOF DRAINS. ALL ARE DRAINING AS DESIGNED. ALL OKAY AT THIS TIME." No cause is stated on th

The bright trim strip along the front edge of the shifter panel in the center console of my 2024 Volvo XC90 has fractured in two places, leaving an exposed jagged edge adjacent to the cupholders. That edge lacerated my fingertip on July 14, 2026 and again on July 25, 2026. On both occasions I was driving the vehicle on a highway and was reaching for a cup in the cupholder, which is ordinary use. The injury bled heavily both times and was a significant distraction while I was operating the vehicle at highway speed. Neither injury required medical treatment. The panel has never been removed, pried, or struck, and no object has been dropped on it. The vehicle has approximately 31,151 miles and was purchased as a Volvo Certified Pre-Owned vehicle in September 2025. It is scheduled for service at an authorized Volvo dealer on July 31, 2026. I have photographs of the fractured trim.
