2020 Subaru Ascent: engine stalls while driving

Filed Apr 20, 2026 · Fuel system, Transmission · DC

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.

The contact owns a 2020 Subaru Ascent. The contact stated that while his wife was driving at 55 MPH, the vehicle stalled. No warning lights illuminated. The contact stated that the failure was related to the federal safety agency Campaign Number: 21V955000 (Power Train). The vehicle was towed to the local dealer where it was diagnosed that the transmission needed to be repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 62,000.

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.

I was almost in two accidents. Back on July 26,2021 I reported to the dealer that the car almost stalled twice, when I am coming to a yield or slowing down and then you accelerate The car has no power. You have to try to pull over before you get hit from behind. Then you step on the gas and it goes again (it does not completely stall) I did not know of any recall on the car but in the October issue of consumers reports it said they have a problem with the fuel pump It sounded like my same problem. I went back to the dealer on 10/14/2021 they went with me for a road test of course it did not happen. They said they cant do anything because my vin no. is not on recall. They can not find anything wrong with the car. Also, I feel the car hesitates when you step on the gas. They say no its normal. recall No 21v58700 7/28/2021 -- subaru recall no WRG-21

the federal safety agency Recall Number 21V587. Cracked fuel pump potential due to improper manufacture, resulting in stalling, vehicle not starting or other fuel pump failure-related issues. Stalling while driving could result in an accident. Subaru’s recall notification should begin in September. Our family will be driving from NC to Maine on August 27 and returning on September 15. We need to know if 1) our specific Subaru Ascent will be recalled and 2) if so, if we can get the fuel pump replaced on our 2020 Subaru Ascent before 28 August 28. Jack Bacheler
