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 and remedy
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.

What owners wrote

“The battery drains prematurely. I have been stranded waiting for 3 + hours for roadside assistance due to dead batter 3 times in December 2021. The dealer told me that due to the number of computers in the 2019 Subaru Acsent that it had to be driven at least twice a week to avoid this problem. The dealer had to replace the battery under the warranty because it burned up when they tried to charge it. touring sub”

“Recently have had issues with the battery. I've had to jump the car 4 times in the last month. The car was purchased in August 2021. I believe the electrical system is draining the battery.”

“Left tailgate open for ~5 hours and the parasitic draw of that action left our battery dead. We were stranded in the middle of nowhere and had to get the battery jumped. After getting jumped... our electronics, especially the safety systems were no longer operable.”

Should you keep driving it?

This page can't tell you that. 0 of 137 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
