2019 Volvo XC60

Our Nest Protect woke us at 06:30 am saying it was detecting smoke in the garage. Upon entering the garage it was obvious that the cabin of the car was filled with white smoke. Disconnected car from charger port. Attended to drive car out of garage to protect the house, but opening the door just let smoke billow out. Closed the door and called 911. Fire truck arrived - the winched the car out of the garage to protect the house. Using their thermal imaging camera determined the hybrid battery was the hotspot, not any of the charging connections. They ran water into back seat where that battery is located for over two hours to keep it from pop further thermal runaway. Clearly an internal EV battery short. Fire fighters had a sensor and detected residual HCN (hydrogen cyanide gas) and I had to be treated at the ER as a precaution as I inhaled a large amount of smoke when I opened the car door initially.

Let me Preface this with, my Make, Model, and year for these problems have been recalled back in 2021, however I was not the owner then and my VIN was not listed as an affected vehicle i guess, nonetheless the problem is exactly the same as experienced by those that were listed on the recalls in the past. Im the 2nd owner of this vehicle and I have owned it for almost 3 years now. In July 2025 after a summer rain in so. cal, I was a couple blocks from home running errands and after being stopped at a light, i began to accelerate and felt like the vehicle was loosing power, I made it home but definitely not able to go the speed limit and once i got home I couldnt shift it into any gear and the vehicle would not turn off. So I had to remove the fuses under the hood, I left them out for a few hours and let the car sit off in my garage during that time. I later came back put the fuses back in and then the car wouldnt turn over. I had it taken to the dealership by AAA and thats when i first learned of the sunroof leak, I contacted Volvo Headquarters and got no help and explained all of the same to the service dept at the dealership working on my car. Long story short the dealership allegedly found water under my interior carpet which obviously damaged modules, I am still paying on that repair. Fast forward to October 2025, same thing all over again only this time the dealership tells me essentially its on the house, however they had my car 3 weeks and did no repairs only got water out of it once again and “brushed off some corrosion”. When I pick it up, it immediately starts funny, i turn the car off and walk right back into the service dep t& raise my concern, to which i was told they had no problem with a hard start up, and we go out to my car & it starts up fine, so i leave 4 days after I got my car back, the check engine light comes on, & immediate warning of reduction of engine power & sure enough thats what it did. today it enters safety mode & wont start

Three incidents have occurred in three months. Unintended Acceleration Incident #1. While turning right after a full stop on an uphill incline, the vehicle accelerated so quickly that the steering wheel couldn't be return to the neutral position before hitting a roadside signpost approximately 25 ft away. The impact was severe enough to cause the right front headlight to be broken, the right front wheel well liner to be ripped out, the right A-pillar to be dented, and the right mirror to be ripped off. No physical injuries occurred. Unintended Acceleration Incident #2, six weeks later. While on the same incline as incident #1, after removing my foot from the accelerator, the vehicle continued to accelerate, even during braking. Total time was approximately 2 sec. There was no damage to the vehicle, and no physical injury. I checked, and the floor mat was locked in place. Both incidents were reported to Volvo, and permission was given to extract data from the vehicle. The data was extracted at a Volvo service center. Unexpected Acceleration Incident #3 (after data extraction, before Volvo report). While turning right and into a parking space in front of a sidewalk and coming to a stop on an uphill incline, the vehicle quickly moved forward approximately 2 ft after my foot was removed from the brake. I was able to brake again to regain control and put the car in park. Unexpected Acceleration Incident #4 (after data extraction, before Volvo report). While traveling on an uphill incline, after removing my foot from the accelerator, the engine remained at a high enough RPM to sustain forward motion. Even after full-stop braking, the vehicle would move forward on its own, on an uphill incline, without depressing the accelerator. After incident #4, Volvo reported that they concluded that the vehicle was operating as designed at the time of their inspection and during a test drive, that no fault codes were found, and that no unintended acceleration was observed.
