What the defect is

Subaru of America, Inc. (Subaru) is recalling certain 2019 Ascent vehicles. The transmission hydraulic sensor may inaccurately measure the hydraulic fluid pressure.

What could happen

If the fluid pressure is measured higher than its actual value, the hydraulic pressure will be reduced. If this occurs, the transmission drive chain may not have the proper tension, resulting in a loss of drive power and an increased risk of a crash.

What gets fixed

Subaru will notify owners, and dealers will reprogram the transmission control unit. The hydraulic sensor harness will be replaced on vehicles with certain stored diagnostic trouble codes. In addition, any vehicle confirmed to have experienced low drive chain tension will have the transmission assembly will be replaced. All repairs will be free of charge. The recall began January 31, 2020.

Your rights

A safety recall repair is free. Under US federal law the manufacturer must fix a safety defect at no cost to you — no charge for parts, labor or diagnosis — whether or not you are the original owner. A dealer cannot charge you for recall work, and cannot require you to have bought the vehicle from them.

That entitlement is not unlimited. It applies where the vehicle was first sold less than 15 years before the recall was announced — 5 years for tires. Past that a manufacturer may still do the repair free of charge, and many do, but they are no longer obliged to. This recall was reported on 2 December 2019.

To arrange the repair, contact any franchised dealer for the brand. If a dealer refuses the work or tries to charge for it, you can report that to NHTSA at nhtsa.gov/recalls or on 1-888-327-4236.

Everything on this page — the models listed, the build dates and the repair figures — comes from the manufacturer's filing to NHTSA and describes the vehicle line as a whole, not any individual car. Only the manufacturer can confirm whether a specific vehicle is affected, and whether its recall work has already been carried out. Check yours by VIN and read the official notice at nhtsa.gov/recalls.

Additional notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

Check your own vehicle

This page describes the recall, not any one car. To see which recalls cover a specific vehicle, search by make, model and year.

A VIN lookup here identifies your vehicle and shows recalls issued for that make, model and year. It cannot tell you what is still open on your individual car - only the manufacturer knows that. Search by VIN instead, or check your VIN at nhtsa.gov for whether a recall is still open on your individual car.
