2022 Volvo XC60 Brakes Problems

At the end of a downhill cloverleaf coming coming on and off a highway, the car slowed to a crawl but would not stop. It was going slowly as if "creeping" like when in B mode but was not in B mode. The brakes would not stop it. I was able to shift gears from Drive to N to P but no response, car continued to creep forward until it gently bumped into the back of an 18 wheeler. There was no collision alarm at the time. I turned the car on and off, and powering down seemed to re set the issue, but the collision alarm went off like 10 minutes later when there was nothing to set it off (seemed like it was just delayed). No error code came up, nothing. I submitted my claim to Volvo, esp since there are similar recalls so I thought it was a known thing, but apparently not reported on my exact make and model (there were not very many made). I did not know there was damage to my vehicle, and the truck driver and myself did not even get out, he didn't feel me, and I assumed the bumper just bumped him so no police report. This was an intermittant failure and after I re booted the vehicle I slowly drove home after brakes seemed to be working after power on/off. I did not know that it was my HOOD that bumped the truck. I did not know there was damage until I got home. If this car's make and model were NOT included in the recall, they should be. TERRIFYING. And volvo did not acknowledge or reassure. requested documentation on what they inspected, and did not receive.

I have had 5 visits with problems with engine , braking sensors, and automatic braking incidents when no obstruction is noted. Propulsion System failure has occurred 3+ times and turtle mode has come on and limited my speed to 30 MPG. It has also started bouncing and shaking while in reverse. I am extremely concerned about the safety threats and lack of consistency when taking it to be repaired.

The vehicle is basically new and I have only had it a few months. It has already been with the dealer three times because of technical/computer/infotainment issues. The dealer had the vehicle for about a week on each occasion. Today, I started to break so I could turn the car around and park it in the parking lot. I was moving very slowly, as you would expect in such a case. However, the car didn't stop but instead lurched forward in full throttle causing me to crash into a breezeblock wall. The automatic warning system did not sound and the crash detection system never engaged. I haven't been in an accident for 30 years and was not distracted when this happened. If the vehicle hadn't already had issues, I would accept user error as the problem, however in light of the car's history, I have doubts.

electrical Emergency break do not function in steep slope, project message “the emergency break can hold vehicule weight” seriously that scare me

2 incidents occurred during the week of Christmas (1 before and 1 after) in which the Rear Auto Brake engaged without warning or provocation. There were 0 obstacles, vehicles, or persons in the vicinity which would have required an alert or braking. The 1st occurred in a parking lot and the 2nd occurred when backing out of a private garage. In each instance, another adult aside from the driver witnessed the malfunction. 1 incident occurred in January in which the Rear Auto Brake engaged without warning and without presence of obstacles, vehicles, or persons in the vicinity which would have warranted an alert or braking. At each incident, the words Rear Auto Brake Intervention or something similar appeared on the dashboard. The braking and screen message occurred with warning or any cause for the sudden and forceful automatic braking. After the 3rd incident, the owner found the option to disable the Rear Auto Brake Intervention feature but this needs to be done at each new drive. No accidents occurred. The owner took the car to the dealer's service department. The service department was unable to duplicate the issue nor were they able to find any record of the error in the vehicle's "black box." The car remains with the service department due to subsequent issues experienced and reported on this site by the owner.
