As a result, the customer will not be able to receive any Firmware Over-The-Air (FOTA) updates due to a VIN / H/U serial number mismatch. In order to ensure compatibility with future FOTA updates, the Retailer must capture the complete 28-digit serial number of the NEW H/U and share that information with SOA. The preferred method for sharing the information is by submitting a COMPLETED QMR which should include a clear photo of the serial number label for use as a cross-check to ensure accuracy. This same procedure is required if a Harman Head Unit is swapped from another vehicle then left in the “new” vehicle. In this case, same as above, submit a COMPLETED QMR which also includes a clear photo of the serial number label for use as a cross-check to ensure accuracy along with the “new” vehicle’s VIN.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10165508-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10165508-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10165508","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"equipment","name":"Equipment and accessories","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"SUBARU","model":"SUBARU","year_from":null,"year_to":null,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
