Vehicle has completed all transmission recalls. Until recently, Subaru continued to say that the issues I was experience with loss of power or glitchy shifting could not be duplicated. After the vehicle exceeded it's warranty coverage, they were suddenly able to duplicate the problem and say that the CVT was causing my problems, that reprogramming failed and that the vehicle needs a new transmission. These issues have persisted before and after the recalls related to the CVT and have cause two near accidents as I pulled out into traffic only to have the car not shift/accelerate as expected. I no longer allow my teenagers to drive the vehicle due to this safety concern. I firmly believe the prior recalls were not effective in resolving the issues with the CVT and/or that Subaru said no damage to the chain was visible and checked the recall as done without actually doing anything more than reprogramming. I believe the issues should be looked into further and coverage for the CVT should be extended beyond the initial reprogramming provided by the recall.

I have been asking Subaru to fix the transmission for 2 years now. It seems like it’s going to stall between 20-25 mph and 45-50 mph. There is a torque converter shutter but I’m told that the car is fine. Subaru corporate has 2 case files for this issue now.

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 and it did the exact same thing I explained and he still said they couldn’t find anything wrong with it. I know this isn’t normal because when we first bought it, it did not drive like this. I’ve also had multiple people tell me they are experiencing the same exact issues. This has been going on for about a year now. It also has been doing a few other things as well.

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) multiple times throughout the spring and summer awaiting parts for the TCM recall with the assumption that this could be the issue. However , my vehicle passed the recall and even after the new TCM was placed on 8/19, I again had the same event on 10/1. Vehicle was taken in on 10/6 for diagnostics on this issue again and nothing found. I do not feel like the dealership has been accurately documenting my issues so I will need to be more persistent in getting someone to address the problem as this could be a serious safety issue.

My Subaru Ascent stopped dead while I accelerated to go on the interstate. All the idiot lights came on. The steering stopped working, the gas acceleration stopped working and my Subaru Ascent 2019 died in the middle of the interstate. I had to pay $150 for a tow to the nearest Subaru dealership, even though I was 65 miles from my home. It would have cost $450 to be towed to my local dealership. The dealership wouldn’t tell me if this was covered by warranty because they didn’t know. I was at about 65,000 miles and my original warranty had ended. In the end, Subaru replaced my transmission but never gave me a loaner. Subaru also kept saying it would be done soon, but took a week. In the mean time I had to find a way to work, and pay the tow bill. Now, my Subaru Ascent is feeling like it did before, such as hesitation when stepping on the gas. I believe Subaru put in a transmission that was the previous recalled one. I also believe that Subaru lied to me about putting in a brand new transmission. I have tried to make a service appointment for the recall and problems with the transmission, but there are no appointments available. I stopped looking when I got to the bookings that were a year out. No warning lamps before this, just hesitation when stepping on the gas pedal.
