Vehicle software update removed safety items. I.e., when vehicle is in motion and is in Pilot assist mode lane avoidance audio warning sound and steering wheel pull back, crash avoidance audio warning sound (when not in cruise control). Pilot assist no longer works at all. Volvo states software updates removed these items. Issue is= I was not informed of the removal of these items. I bought the car because it was equipped with those items. Volvo removed them without my permission or even notifying me the update would degrade my vehicle. Volvo states they are unwilling to remove the software or even modify it for individual customers. These are safety issues. Volvo complaint reference number is available if needed. Vehicle mileage 38026. Bought new in 2016 September.

The vehicle lost all power while I was driving on a freeway. The power came back on, (showing certain features but not all) briefly for a minute and then shut down again. In addition to this problem, a consistent issue that has happened no less than 6 times over the course of a year is the vehicle interprets there is something in its path and slams on the brakes when there is nothing in its path. There is no car, person, object, plant, etc. In the way of the vehicle at all.

1) adaptive cruise control suddenly shuts off while driving on the highway, error message appears on the screen: "windscreen sensor, sensor blocked, see owner's manual", the appearance of the sensor on the outside of the car appears clean and even after scrubbing the sensor area the error still occurs. The car has been repaired for this same problem over 5 times including total replacement of the the windscreen sensors, with the problem still persisting. 2) dashboard went blank and computer rebooted while driving.

I was driving on the freeway in rush hour traffic in eco drive mode with the auto start/stop function enabled. The auto stop kicked in and stopped my engine, but when I went to press on the gas pedal, the auto start did not restart my engine and the gas pedal was unresponsive. No alerts or warnings popped up - everything remained on (headlights, radio, etc), and nothing appeared wrong except for the fact that the car wouldn't move/accelerate. I was going around 1mph at this point, and pulled over to the shoulder, parked, and restarted the engine manually. I then drove home without further incident. I brought in the car to the dealer the next day. The response was that there was nothing to fix B/C no codes showed up during the diagnostic, and they weren't able to replicate the issue. They downloaded "software 1 and 2" and said that might fix the problem but they don't know. They said corporate doesn't tell them what the software updates do, but it seemed like the update mainly pertained to the radio which clearly has nothing to do with my issue. They tried to return the vehicle to me a week later (11/27) and I refused, and asked them to escalate the issue B/C I didn't feel the car was safe and there was no resolution. They assured me that corporate's field tech specialist was consulting with them on the phone and agreed the car was fine to be returned to me B/C there were no codes and the issue couldn't be replicated. I spoke to corporate (Volvo North America) and they said they would escalate on their side but had no specific details to reassure me the problem was taken care of. I asked for a flight computer to be installed to log the car data in case the issue happens again, and no answer on that request so far. I got the car back today (12/8) B/C they don't know how/what to fix. The dealer has mechanics and not the software engineers that need to look at the car.
