“This submission supplements NHTSA Complaint #11759206, filed on August 24, 2026, regarding a 2018 Volvo XC90, in order to provide additional relevant information that came to light after the original filing. At the time of the first safety-critical malfunction (in-vehicle warnings including "Transmission Acceleration Performance Reduced" "Gear Lever Locked" and related electrical system symptoms), the service manager at Volvo Cars Brooklyn was able to remotely diagnose the likely cause by telephone, before the vehicle was even towed to the shop, specifically instructing the owner to check for dampness under the driver's floor mat, which was confirmed to be present.
