My 2020 Subaru Ascent struggles to retain power when accelerating, especially from stopping and especially when the fuel is low. The vehicle stalls or loses some power when trying to accelerate. The check engine light is not on and there is no other indication that there is a problem with the vehicle. I have discussed it thoroughly with my mechanic and we both think it sounds like a fuel pump issue. He looked at the other Subaru recalls and thinks my vehicle should be included in the other Subaru fuel pump recall (the federal safety agency ID Number: 21V587000). Does my vehicle qualify for this fuel pump recall? Thank you.

Issue 1: Complete transmission failure was diagnosed by Subaru dealer March 24, 2026 at 5 years and 6 months after purchase with an odometer reading of 45,000 miles (drive train warranty 5 yrs/60,000 miles). Had to purchase and have installed a rebuilt Subaru transmission. First noticed transmission was slipping with a large load in vehicle May 2025 at 4 years and 8 months after purchase at about 40,000 miles on odometer. The issue was subsequently not noticed under typical load until slipping transmission signs reappeared December 2025. Made appointment in March 2026 due to a planned trip to [XXX] mid-February to mid-March. Failed transmission poses critical safety risks including loss of acceleration, stalling in traffic and unexpected deceleration. Subaru of New England was able to install the transmission at about 50% of the initial estimate over $12,000 (final paid $5400). Subaru of America file was claimed (Case # XXX-XXX) for the balance, but any further reimbursement was rejected. Issue 2: Driver window alternating between getting stuck fully opened as well as reversing to the open position when trying to roll up. The failure of window regulator and channel run was diagnosed by Subaru dealer March 24, 2026 at 5 years and 6 months after purchase with an odometer reading of 45,000 miles. Had to purchase and replace the Subaru window regulator and channel run. Power window failures in the open position create significant safety risks including vehicle theft, interior damage from weather and occupant vulnerability.

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.

Transmission completely failed last year April 2021 in the middle of Highway and car is stalled. Tow to dealership for transmission replacement. After almost a 1 year of driving the transmission problem is coming back with gears are slipping again. Took the car to dealership and this time they are doing the repair of transmission instead of replacement. I am not comfortable with the approach since I already bad experience and concerned about repair reliability. Called Subaru North America and waiting for resolution. There is already open recall for CVT transmission for this vehicle but no remedy yet from Subaru. It's safety concern as car broke down earlier in the middle of highway with heavy traffic.

The car hesitates when I step on the gas, feeling like it stalled. This has happened since I purchased the vehicle and the dealer says I don't have a problem. I have pulled out into traffic only to have the car "stall' and I sit waiting to be hit. Subaru had a recall on this in 2020, but the dealer said I did not qualify for anything beyond reprograming. The problem persists. No warning lights or other messages.

My Subaru 2020 with 16,000 miles stalled in the middle of driving down the road in Town, I was driving 35 mph when out of nowhere the car stalled. I was able to coast/turn on to a side street. I’m lucky the car had enough momentum to keep going or we would have been hit by traffic as the street we were on is a busy road. The car flashed all the lights when it stalled and refused to crank over, it was low on gas so I called AAA and they brought 5 gallons of gasoline and filled it. The technician then tried to get the vehicle to start but it wouldn’t. Luckily he offered to tow it to my house for free. I have tried multiple times to get the vehicle to start and it wont. It cranks but doesn’t actually move. I don’t know what’s wrong and now I have to have it towed to the the local dealership. This is the second major issue that has happened. The first one was that the transmission failed and with my car having a branded title for being stolen/recovery. Subaru would not replace the transmission at 7,600 miles and I had to find a used one to replace it with. I now just got the recall letter and have messaged Subaru about it.
