2020 Subaru Ascent: fuel pump failure

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.

We own a 2020 Subaru Ascent we purchased brand new. A few weeks ago we noticed a faint gasoline smell while at a red light. I thought it was a one time occurrence but it has been happening now every time the vehicle is at idle or stopped. I have read on Subaru owner forums about 2019 to 2021 models having this issue all the way from 2100 miles to almost 90,000 miles. Many customers have had to make multiple trips to the dealership to get charged diagnostic fees and many times they say they can’t smell the problem. I just recently contacted my dealership about this issue and found an old service recall about the low pressure fuel pump and was told to not believe everything I read online. This is the vehicle that my family uses and I’m not sure if this is safe for them to be in and is getting to sound eerily similar to when Ford had the CO problem in their explorer and people were crashing. For the amount I paid for this vehicle and all my service intervals at the dealership and many people having the same safety concern I hope this is investigated and I won’t have to pay for repairs.

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

My wife and I purchased a new 2020 subaru ascent in january this year. From day one, the vehicle has been generating an excessive and potent fuel smell in the engine bay that is then pulled into the passenger cabin via the HVAC system while running. This smell is prevalent when walking around the outside of the vehicle while it is running; it is also noticeable after parking (and turning off) the vehicle in our garage as the garage fills with a raw fuel smell that takes several hours to dissipate. We are able to replicate this issue every time we drive the vehicle for more than 10 minutes in all types of driving conditions and trip durations. Outside temperature does not seem to be a factor. The vehicle has been taken into the dealership three times since purchase. On the second visit, the dealership tech verbally confirmed the fuel smell upon check-in and opted to run full diagnostics on the car, even testing the fuel pump/system, but could not identify the source of the smell. This was eventually elevated into a service request incident/ticket with subaru of america. Two subaru field engineers visited the vehicle, the first stated they could not replicate the problem, but the second could replicate the problem but claimed it was a running engine/burning plastic smell and was considered normal operation. The engineer's proposed remedy was to use the "recirculate air" button to prevent outside smells from being drawn into the car. > I am confident this is a fuel smell, not a typical heated engine smell as subaru claims. > when drawn into the vehicle, the fuel smell causes lightheadedness and headaches. > using the recirculate air button is not a solution, it is a mitigation tactic, especially when that smell is continually generated by the running vehicle.
