Recalls (4)
Subaru of America, Inc. (Subaru) is recalling certain 2019-2020 Ascent, 2020 Legacy and Outback vehicles. A programming error in the Transmission Control Unit (TCU) may allow the clutch to engage before the drive chain is completely clamped.
Risk: An improperly secured drive chain may slip and break, causing a loss of drive power and increasing the risk of a crash.
Fix: Dealers will reprogram the TCU, inspect TCU data for chain slip, and visually inspect the chain guide. If evidence of chain slippage or damage is found, the transmission will be replaced. Repairs will be performed free of charge. Owner notification letters were mailed August 19, 2022. This recall includes all vehicles previously recalled under 19V-855. Vehicles previously recalled under 19V-855 will need to have the new remedy performed for this recall once available. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WRK-21.

Maintenance & Warranty
Recommended Subaru ASCENT Service Intervals
Boxer engines have specific oil consumption patterns — check oil monthly. CVT service every 30K is critical; skipping shortens life dramatically. AWD requires matched tire wear.
"Severe service" conditions (heavy towing, extreme temps, city stop-and-go) typically halve these intervals. Always consult your vehicle's owner's manual for the authoritative schedule.
Subaru New-Vehicle Warranty Coverage
These are the terms for a new Subaru. If you're buying a used 2020 ASCENT, remaining coverage is usually pro-rated from the vehicle's original in-service date. Not all coverage transfers between owners — check with a Subaru dealer for VIN-specific remaining warranty.
Estimated Repair Costs
Estimates based on average reported repair costs. Actual costs vary by location, shop, and severity.
