  ELECTRICAL SYSTEM:WIRING:INTERIOR/UNDER DASH

  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.

    Battery would drain to the point where it would need to be jumped to start. I carried a jump starter in the car during the cold months. Finally took car to be inspected and they told me that the problem was my battery and that I needed to replace it with a $465 battery. I’ve been dealing with this issue for 2 years and now I have found out that the car has a defect that drains the battery.

    This car is having constant problems with the battery failing. It especially fails when we are going to any type of trip where packing the car is a process that takes time. The battery dies on us often and is unpredictable, leaving us stuck often. I bought this car because I want a RELIABLE car. At any moment we could be stuck somewhere with my kids. No warning comes on to prevent this from happening.
