Rear-View Camera Failure

What NHTSA investigated

On November 23, 2022, American Honda Motor Co. (Honda) filed recall 22V-867 to address a loss of the Rear-View Camera (RVC) function in model year (MY) 2017-2019 Honda Ridgeline vehicles. On May 3, 2024 Honda filed another recall, 24V-321, relating to the loss of the RVC function in MY 2020-2024 Honda Ridgeline vehicles. The production parts recalled under 24V-321 and the parts used for the remedy in 22V-867 used the same supplier and materials for critical components in the RVC wire harness. As such, on June 26, 2024, ODI opened Recall Query RQ24011 to investigate the long-term suitability of the remedy in recall 22V-867. After receiving 14 total reports of RVC wire harness failures in vehicles that received the remedy for recall 22V-867, NHTSA upgraded the RQ investigation to this Engineering Analysis (EA25003) to further assess these failures. Recall 22V-867 states that the RVC wire harness was manufactured with a protective corrugated tubing that was insufficient to protect against bending wear and zip ties that were insufficiently tightened and would not keep the protective tubing in place. The consequence is that the RVC wire harness may fatigue and break after the tailgate is repeatedly opened and closed. This ultimately results in the failure of the RVC to display an image due to a lack of connectivity. Honda’s remedy, as identified in the recall filing, was a replacement harness with longer protective corrugated tubing and sufficiently tightened zip ties. This remedy part was also installed as a production part in certain MY 2019 Ridgeline vehicles. Recall 24V-321 states that the RVC wire harness was manufactured with a material which was susceptible to breakage upon repeated opening and closing of the tailgate, which ultimately leads to a complete loss of RVC function. Honda’s remedy identified in the recall filing was a replacement harness manufactured by a new supplier with improved material properties to withstand wear from bending. Since the remedy parts for recall 22V-867 and the production parts recalled under 24V-321 use the same supplier and materials for critical components in the RVC wire harness, ODI opened this investigation. To date, ODI has received 4 allegations of RVC failures.  Honda reported a total of 27 complaints of RVC failure. ODI’s analysis of these reports revealed that the majority of these reports are related to different failure modes within the RVC or harness. Thus, these reports cannot be attributed to the durability concern being assessed in this investigation. During the investigation, ODI utilized NHTSA’s Vehicle Research and Test Center (VRTC) to analyze further the potential safety related consequence and frequency of the alleged failures. VRTC surveyed owners of the subject vehicles in Ohio to collect additional information on the presence of RVC wire harness failures in vehicles subject to recall 22V-867. VRTC also performed inspections of select vehicles identified from the survey responses. The survey responses received and results of inspections did not show any RVC failures resulting from wire harness damage. Additionally, VRTC completed durability testing on the subject wire harness in an attempt to duplicate the failure mode. The test results indicated that the subject part is not expected to fail within a reasonable vehicle life span. As a result of ODI’s analysis of the field data and available test data, this Engineering Analysis is being closed without further action. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency reserves the right to take additional action if warranted by future circumstances.
