Mild hybrid vehicle that was purchased 4/20/2026. Volvo service states incident on 06/10/2026 was caused by vehicle running overnight in enclosed garage. Volvo also states that cause was due to item inserted into drivers seatbelt buckle. No warnings posted regarding this would cause the vehicle to turn on once car was parked and driver door shut and run continuously throughout the night in an enclosed garage. Volvo claims every time the driver door is opened, it shuts the engine off. This is not true! And this situation proves that. Vehicle still currently at dealers to be repaired so unsure if components are available for inspection. Components damaged are: Midvoltage battery, midvoltage Converter module, starter generator module, 12v battery. The vehicle became extremely hot and would have caught on fire had our smoke/co detector not gone off. CO was detected in house and garage. Volvo refusing to take any accountability for this situation and refusing to provide me the documentation for the findings of my vehicle.

I believe this is a major (and known) software issue, but the car has on several occasions, when stationary, entered a state where all of its controls are unresponsive and the engine cannot be turned off. *Nothing* related to the operation of the car works, including the electronic handbrake, gear selector OR the stop/start button. This is an exceptionally dangerous fault, as the car engine cannot be turned off, and the "handbrake" cannot be engaged. Getting out of the car and locking/unlocking it with the remote does not initally clear the problem. Sometimes it resolves by itself after several minutes. We think that maybe pushing and holding the stop/start button sometimes helps, but it is not clear that this is the case. Rebooting the software system onces the car has "woken up" again has not fixed the problem. Volvo dealers are apparently aware of the issue, but a massive software update by Volvo has not resolved it in any way -- if anything it is worse. Frankly, Volvo should not be permitted to sell cars to the public until this is completely resolved, and cars are recalled for a *real* (as opposed to supposed) fix. I thought you should know. (The date given below for "when this incident occurred" is simply the most recent occurrence.)

The car starts vibrations on at 70 mph through 80 mph. I have brought it to the dealer who stated they felt it and declared that it is normal for severe vibrations to occur at only these speeds. Volvo refused to acknowledge or treat the issue. This issue has been reported and Volvo issued a Technical Journal 36752.2.0 which directs the technicians to acknowledge the vibrations but will provide no solution. This is a safety issue if your car vibrates at highway speed. How has Volvo been allowed to sell these cars without warnings?

Despite multiple repair attempts by Volvo Cars Sugar Land — including software reloads, module reprogramming, and the completion of Recall R10333 — the vehicle continues to experience failures that directly compromise my safety and the safety of my wife. I no longer feel safe operating this vehicle. My XC40 has undergone five documented repair visits, including: • Electrical system failures • Infotainment instability • Parking sensor and camera malfunctions • Multiple software reloads and module reprogramming • Recall R10333 “Total Upgrade” On March 11th, while driving at approximately 60 mph on the highway, the IHU screen froze, went completely black, and all audible safety indicators inside the cabin were lost, including: • Turn signal click • Hazard flasher sound • Parking sensor tones • Multimedia audio This condition lasted for nearly 10 minutes, during which I had no ability to safely signal lane changes or rely on audible warnings. I was forced to continue driving until I could safely pull over. After parking, shutting the vehicle off, and waiting several minutes, the IHU restored itself. This incident occurred five days after the most recent repair attempt and represents a serious safety hazard and a complete loss of trust in the vehicle’s reliability.

My car randomly has a battery charging fault. An alert stating “stop safely 12V battery critical charging fault” will just pop up while driving and then put the vehicle in turtle mode. This is an intermittent fault and is likely a false indication. This could cause an accident because it causes the car to slow down. This could happen on a highway.
