| Power Train problems |
This is my daughters vehicle. She was driving home from work with my [xxx] and [xxx] grandchildren in the car. The car suddenly wouldn't drive at a safe speed and was chugging along. She almost got into an accident because she couldn't go faster than about 12 mph. She as finally able to pull over in a safe location and called aaa. My son in law met her and picked her and the children up. The vehicle was towed to Volvo in buffalo NY. The diagnosis was a known leak in the sunroof that causes the drains to become blocked. Water then runs down and burned out the ecr module that is located beneath the drivers side foot well. Volvo is aware of the problem and is currently checking all vehicles for the blocked drains. They were given a 5000. 00 estimate for repairs. Today Volvo refused to repair it at their expense. There should be a full recall on this issue. I am a fire/explosion investigator who has investigated numerous car fires related to control modules catching fire. This could have caused a fire and trapped my grandchildren in the rear seat. The dealership reported 2 other vehicles in for the same issue. Please review and respond to me- [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
The contact owns a 2020 Volvo Xc90. The contact stated that while driving 35-40 mph, the message "vehicle not in park" was displayed intermittently, and the vehicle stalled. The contact was able to pull over to the side of the road. The vehicle was restarted after several attempts and was driven to the residence. The vehicle was then taken to the dealer, where the contact was informed that no failure was found. The vehicle was not diagnosed or repaired. While investigating the failure online, the contact became aware that it was a common failure, and that the dealers were unable to duplicate the failure. The manufacturer was not notified of the failure. The failure mileage was approximately 79,000.
The vehicle shudders randomly when taking off from a stopped position around 18mph. The vehicle shudders randomly when slowing down to make a right turn. The vehicle shudders when driving at higher speeds. It's not a violent shudder, but those riding in the vehicle feel it as well. The safety concern is two fold in that there is a fear of losing control at an inopportune time. Secondly, the constant shuddering over time is going to result in damaging other part of the vehicle, particularly the engine, that will present a safety hazard while driving. The vehicle was purchased used(certified). The dealer replaced collapsed engine mounts on left and right side and considered it resolved. Forman at dealer stated it is common with Xc90's to have engine shudder as if this should be accepted. Because the engine shudder is happening at higher speeds now, we're going to return to dealer, but I do not expect a solution. I've seen others report similar issues with shuddering on Volvo forums and I haven't seen 1 solution that worked. This is a problem in a lot of Xc90's. The attached documents also contain some attempted fixes to correct a drifting issue.
