   The Y pipe that connects the exhaust from the engine to the turbo charger, has cracks from poor welds. It happened 8-12 months ago we started to notice that during warm up our Ascent would sound real loud then quiet down once it warmed up. We didn’t know there was an issue as there were no lights that came on and we had no loss of power or MPG. The safety issue would be that we finally took the car in once we started to smell exhaust fumes coming from the car that we would…

   During an inspection at the dealership in December 2023, the tech found the oil pan to be leaking. It was resealed during the same visit. Approximately 8 months later, the same problem was found again at the dealership. It was again resealed. Upon further research, this appears to be a recurring problem on similar vehicles.

   Purchase the car two weeks ago the first night on the way home it was acting up just like it did when I test drove it and was told by the BMW dealership Aristocrat Motors in Topeka Kansas that they would fix anything that was wrong with it. On the way home I realized I didn't think it would make it back the 60 miles so I took it to Olathe Subaru they informed me that it had had transmission problems reported by the previous owners but their technician couldn't get it to do…

   Over the course of 5 years, a lot has been mechanically wrong with our vehicle. Each service appointment yielded a 'cannot duplicate' response. Recently, my car has been in the service department a few times. My car had recall work performed on a ground bolt, and my husband advised them that the car had a 'rich fuel' smell when starting with the hood open. I've complained since 2021 of a smell when pulling up the mountain. The smell is what I described as a perm solution…

Car only has 70,000 miles on it. Also, when car is started at times, there is a very prominent cloud of smoke that comes from the exhaust.

    As I am going up a hill I will be pushing on the gas and the engine will rev up loudly and the rpm will increase but the vehicle speed won’t increase or it decreases as I’m trying to accelerate. This is dangerous because the people behind me are expecting me to be speeding up to go up the hill but my vehicle will be slowing down and won’t let me increase speed. It has been to the dealer multiple times and they say they can’t find nothing wrong. We drove the mechanic around…

    Vehicle has experienced total loss of power while driving under normal circumstances. This has occurred in a drive-thru, at 45 and 50mph, and also twice during 70mph highway driving. The entire vehicle shuts down and multiple dash board lights illuminate at the time of power loss. I first documented this on 4/7/22 and it randomly occurs every month, once it even happened twice in the same day. I had called the dealership (where I purchased the vehicle and have it serviced)…
