Subaru is announcing this recall to encourage owners of affected vehicles to contact an authorized Subaru retailer as soon as they receive notification of this recall from Subaru of America. The ground bolt that secures the ground terminal of the Positive Temperature Coefficient (PTC) heater may have been improperly fastened during vehicle production. This potential condition may result in the melting of the ground terminal and surrounding components, increasing the risk of fire when the PTC heater is in operation. There have been no crashes or injuries due to this issue. For all the potentially affected vehicles, Subaru retailers will replace the PTC Heater Ground Bolts and replace the ground wire and connector holder if necessary. A small percentage of vehicles, estimated at 0.6%, will require ground and connector replacement. The inspection and repair will be completed at no cost to the customer. Until the inspection and repair is completed by an authorized Subaru dealer, customers are being advised to park their vehicle away from garages, car ports, or other structures, and to avoid leaving the vehicle unattended while the engine is running. If an owner notices or smells smoke coming from the dash or driver’s footwell area, they should immediately stop operating the vehicle and turn the ignition switch to the “off” position. If this occurs, the owner is advised to immediately contact Subaru’s Roadside Assistance program or nearest Subaru retailer for assistance. Vehicle owners will be contacted by mail within 60 days.

As a result, when the PTC heater is in operation, electrical resistance may increase, leading to the generation of heat. If the contact surface between the ground terminal and ground bolt is sufficiently limited, the excessive heat generated could result in melting the ground terminal and surrounding components. FMVSS 1 : NR Part 573 Safety Recall Report 22V-907 Page 2 The information contained in this report was submitted pursuant to 49 CFR §573 FMVSS 2 : NR Description of the Safety Risk : If the ground terminal melts, there is an increased risk of a fire. Description of the Cause : Obscured access to the ground point may not have allowed the ground bolt to achieve a proper tightness during production assembly. Identification of Any Warning that can Occur : Owners may notice a burning smell and/or smoke from under the driver’s side instrument panel area. Involved Components : Component Name 1 : SCREW Component Description : TAPPING SCREW – HEXAGON HEAD Component Part Number : 904580002 Supplier Identification : Component Manufacturer Name : Subaru Address : NR NR Country : NR Chronology : January 9, 2020 – Air tools introduced to the production line (replacing battery tool) January 11, 2020 – Subaru received the first technical report exhibiting smoke from the driver’s side interior cabin September 29, 2021 – Subaru received the first technical report involving fire damage. While a vehicle inspection identified the area of origination, a root cause could not be determined due to the significant damage caused by the fire. February 24, 2022 – Subaru received the first technical report exhibiting smoke on a vehicle produced after the Jan 9, 2020 tool change April 29, 2022 – Subaru changed line tooling to DC tools capable of detecting torque and rotation angle May 2022 – Subaru received the first technical report from the U.S. market involving fire damage on a vehicle produced after the Jan 9, 2020 tool change. May-July 2022 Subaru conducted testing and evaluation to determine the specific conditions required to generate the heat necessary to cause the melting conditions being observed. It was determined that contact surface area was the primary condition. Low torque was a secondary condition. August 15-30, 2022 – Subaru conducted a field evaluation study to understand the potential scope of the issue Part 573 Safety Recall Report 22V-907 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 beyond the few incidents that were reported. December 1, 2022 – Out of an abundance of caution, Subaru decided to conduct a voluntary safety recall. Subaru is only aware of 11 technical reports in the U.S. market. Subaru is not aware of any crashes or injuries resulting from this condition. Description of Remedy : Description of Remedy Program : For all the affected vehicles, Subaru dealers will replace the PTC heater ground bolts and, if necessary, replace the ground wire and the connector holder. • As a precautionary measure, it is highly recommended that owners park their vehicle away from any garage, car port or other structure until this repair is completed. • Additionally, owners should never leave the vehicle unattended while the engine is running until this repair is completed. • If an owner notices or smells smoke coming from the dash or driver’s footwell area, the ignition should be placed in the “off” position and the vehicle should not be operated.
