2024 Volvo XC90 B6 problems

“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.”

“The Infotainment Head Unit (IHU) on my 2024 Volvo XC90 has experienced repeated total system blackouts, spontaneous power-cycles, and critical thermal failures while operating at highway speeds (46–77 MPH). The IHU displays a "Cooling Infotainment System" critical warning and fails completely, resulting in total loss of the federally mandated rearview/backup camera (FMVSS 111 violation), GPS navigation, and all safety interfaces while in motion. The dealer confirmed the defect and attempted repair twice but only performed software resets rather than hardware replacement. The dealer documented "FIXED FAILED." Failures have continued and worsened after both repair attempts. Video documentation exists for all incidents (Exhibits A–H, dated May 2–7, 2026, odometer 41,900–42,151 miles). The vehicle's own diagnostic system issued a Critical Thermal Warning on the driver cluster while navigating traffic, confirming a hardware cooling defect. Two failures occurred during active driving maneuvers including a reverse maneuver and highway operation on I-20, creating immediate safety risk to the driver and public. The component is available for inspection. The defect has…”

“Some critical functions on the center display console instrument panel are freezing up while driving - we are unable to change the drive mode while the car is in motion. This has not happened before, and it is glitching a lot lately. The display has been extremely slow and unresponsive, and the problem is multiplied as all critical functions of the car are controlled through the display panel. There were no warnings issued when we tried to change the drive mode. We had to pull over to the roadside, turn off the car for 30 seconds, then restart the car to fix the issue. We have [XXX] and [XXX] ) in the car, so this is becoming increasingly risky to drive this "safe" car by Volvo. We have reported such issues with the display to our Volvo service unit multiple times, and the car has been returned to us with such issues still lingering (despite the service reloading/updating the software multiple times) for the last 6 months since March of this year.”

“While driving 45-50 miles per hour on a large main street in orange county with a car 6-7 car lengths ahead and the Volvo XC90 automatically forced the vehicle to stop on a dime for no apparent reason. Everyone in the car was thrown forward into the locking seatbelts. Thankfully no one was injured.”

“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…”

“1. When the air condition is turned on there is knocking/banging/thumping noise. It starts with a whinning noise and then gets thumping noise and then starts again with a whinning noise followed my a thumping noise. It can go over 15 to 20 mins and then stops and restarts again. Yes, it can easily be reproduced. 2. The whinning and thumping noise while the car is driving can cause a safety issue where something could explode (the way it sounds) or air condition can simply not working as we approach summer. 3. Yes, its been reproduced, I've sent them the videos, i was at the dealership to reproduce and they acknowledge there is an issue. Weaver brother volvo had created an internal case to Volvo Technical Assistance, case number: RTS-US831535. The reply was they are aware about this issue and they are investigating it. The issues seems to be on the expansion valve and they are still investigating it. This was dated August 6th, 2024. 4. No warning lamps or messages or other symptoms. June 26th, 2024. The issue was reported to dealer around July, 25th 2024.”
