NHTSA Complaint #11577253 — 2017 HONDA RIDGELINE

Over the past 15 months, our 2017 Honda Ridgeline has been at the Honda dealership service for over 90 days, or 20% of the elapsed time. A 2nd replacement of the torque converter (3rd unit) in March 2024 has not resolved the judder/vibration, which does not occur when the engine temperature is cold. The vibration is consistently recurring once the engine has reached nominal operating temperature, when the transmission is in 4th-5th gear around 1800 RPM, 30-50 MPH. Based on the dealership-attempted fixes, the dealer believes the issue is due to Variable Cylinder Management (VCM) and Active Control Mount (ACM) degradation. The dealer, in contact with Honda tech line, have no known fix to this systemic defect. The vehicle has been 100% serviced at Fisher Honda per the factory maintenance schedule. All recommended and required service, including Technical Service Bulletins and Recalls have been performed and are up-to-date. Reference earlier NHTSA ID 11554673 (Nov 2023).
