NHTSA's VIN data lists these trims for the 2021 Ascent. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 103 complaints with NHTSA about the 2021 Ascent. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 2 recall campaigns for the 2021 Ascent over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
Subaru of America, Inc. (Subaru) is recalling certain 2026 Crosstrek Hybrid, 2025-2026 Forester Hybrid, Forester, and 2019-2026 Ascent vehicles. These vehicles were manufactured with an incorrect Gross Axle Weight Rating (GAWR) on the certification label. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) 110, "Tire selection and rims."
Risk: An incorrect GAWR label may lead to an overloaded vehicle, increasing the risk of a crash.
Remedy: Subaru will mail a new certification label to owners, free of charge. Owners may also choose to have a dealer install the new label, free of charge. Letters informing owners of the safety risk were mailed August 27, 2026. Additional letters will be mailed once the remedy is available. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WRH-26.
Subaru of America, Inc. (Subaru) is recalling certain 2019-2022 Ascent vehicles. The ground bolt that secures the ground terminal of the Positive Temperature Coefficient (PTC) heater may have been improperly fastened, which could result in melting of the ground terminal and surrounding components.
Risk: A melting ground terminal increases the risk of a fire.
Remedy: Owners are advised to park their vehicle away from structures and to avoid leaving the vehicle unattended while the engine is running. An owner who notices or smells smoke coming from the dash or driver's footwell area should immediately stop operating the vehicle and turn the ignition switch to the "Off" position. Dealers will replace the PTC heater ground bolts and if necessary, replace the ground wire and the connector holder, free of charge. Owner notification letters are expected to be mailed February 6, 2023. Owners may contact Subaru's customer service at 1-844-373-6614. Subaru's number for this recall is WRL-22.
Carmakers sent NHTSA 384 service bulletins and notices that cover the 2021 Ascent, the latest on Oct 5, 2026. They tell dealers how to fix known issues.
The parts they mention most: electrical system (215), equipment (114), power train (46), unknown or other (40), engine (36).
NHTSA hasn't opened a defect investigation that covers this model year.
