Safety Recall: 2023 Honda Accord FHEV e-CVT Replacement

SEOCONTENT-START

Service Bulletin 23-079 August 18, 2023 Version 1 Safety Recall: 2023 Accord FHEV e-CVT Replacement AFFECTED VEHICLES Year Model Trim VIN Range 2023 Accord Hybrid Check the VIN status for eligibility BACKGROUND A resolver is a rotation angle sensor for controlling an electric motor. The generator motor resolver covers in affected vehicles may have been damaged during the manufacturing process. Over time, this damage may cause the cover to separate from the resolver, potentially contacting and cutting the resolver wire harness and leading to resolver malfunction. This malfunction may cause illumination of the MIL, the engine to transition to EV mode with range limited by battery capacity, and/or prevent the vehicle from restarting. CUSTOMER NOTIFICATION Owners of affected vehicles will be sent a notification of this safety recall. Do an iN VIN status inquiry to verify eligibility. Some vehicles affected by this campaign may be in your new or used vehicle inventory. Failure to repair a vehicle subject to a recall or campaign may subject your dealership to claims or lawsuits from the customer or anyone else harmed as a result of such. To see if a vehicle in inventory is affected by this safety recall, do a VIN status inquiry before selling it. CORRECTIVE ACTION Replace the e-CVT transmission.
