general problems of the 2019 Volvo XC60

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.

The speedometer stopped working - no numbers were visible on my dash. It was unsafe as I was not aware what speed I was traveling. This happened on December 24, 2023 and has not happened again after that nor was it reproduced or confirmed by a dealer or service center. The vehicle has not been inspected by anyone. There were no warning lamps/messages/or anything.

The entire vehicle shakes and vibrates violently at 50 mph and over.
