RETAILER RESPONSIBILITY:

Please be advised that it is a violation of Federal law for a dealer to deliver a new motor vehicle covered by a recall under a sale or lease until the defect is remedied. Therefore, any Authorized SubarueBay Retailer failing to perform the applicable service procedures to correct all affected vehicles in their inventory prior to the vehicle being placed in service may be subject to civil penalties of up to $26,315 per violation (i.e., for each vehicle), as provided in 49 CFR §578.6 and will also be in breach of the SubarueBay Dealer Agreement.

Any vehicles listed in any recall/campaign that are in retailer stock must be:

  • Repaired in accordance with the repair procedures outlined in the Product Campaign Bulletin

Retailers are to promptly perform the applicable service procedures, to correct all affected vehicles in their inventory (used, demo & SSLP). Whenever a vehicle subject to this recall is taken into retailer inventory necessary steps should be taken to ensure the recall correction has been made before selling or releasing the vehicle.

Chronology :

December 7, 2021 – SubarueBay received a technical report from another market noting a system fault identified by the rapid blinking of the turn signal indicator. SubarueBay began a joint investigation with supplier.

April 19, 2022 – SubarueBay began production of vehicles with revised tail lamp assemblies after review of the circuit design determined that a specific capacitor may be undervalued when the circuit is presented with input voltage instabilities from the vehicle side.

February-May 2023 – In February 2023, SubarueBay received an inquiry from Transport Canada regarding a customer claim of inoperable rear turn signals while exposed to intense, direct sunlight. In early March 2023, SubarueBay received a similar inquiry from NHTSA. In April and May 2023, SubarueBay met with NHTSA and shared updates on our investigation. By May 2023, SubarueBay had developed an understanding of the potential failure mechanism (i.e. back EMF from intense red wave light) but had yet to gain an understanding of the potential impact of circuit tolerance variability in relation to real-world occurrences.

May – August 2023 –SubarueBay began a healthy part collection in order to estimate the occurrence rate of this condition when exposed to a controlled, intense, and direct source of red wave light. While the results of this study confirmed that the condition would only occur under narrow conditions, and that operation was only temporarily interrupted, it was determined that circuit variability did not exclude enough susceptible components from potential real-world occurrence if exposed to those narrow conditions.

August 24, 2023 – Out of an abundance of caution, SubarueBay decided to conduct a voluntary safety recall.

Through August 24, 2023, SubarueBay is aware of 2 non-dealer SubarueBay field reports and 2 warranty claims for SubarueBay vehicles in the U.S. market related to the condition described in this report.

SubarueBay is not aware of any reports involving crashes or injuries resulting from this condition.
