2018 Honda Ridgeline Recalls

The Office of Defects Investigation (ODI) has received 414 reports of connecting rod bearing failures in the 3.5L V6 engine used in the following vehicles: Model Years (MY) 2018-2020 Acura TLX, MY2016-2020 Acura MDX, MY2016-2020 Honda Pilot, MY2018-2020 Honda Odyssey, and MY2017-2019 Honda Ridgeline.  The subject engine failures were analyzed as part of a Recall Query (RQ24013).  It was determined that these engine failures are outside the scope of Honda Recall 23V-751. Further, evidence gathered in conjunction with RQ24013 does not suggest this failure is caused by the same crankshaft manufacturing defect that is addressed by Honda in Recall 23V-751.  Based on analysis of data from RQ24013, NHTSA has closed that investigation. The significant number of reports of engine failure in vehicles outside the scope of RQ24013 presents a potential safety risk that warrants further investigation.  ODI is opening this Preliminary Evaluation (PE) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues.  To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

On June 26, 2024, the Office of Defects Investigation (ODI) opened a Recall Query (RQ24011) to assess the long-term suitability of the remedy for recall 22V-867, which was filed on November 23, 2022 by American Honda Motor Co. (Honda). Recall 22V-867 addressed concerns of a loss of the Rear-View Camera (RVC) function in model year (MY) 2017-2019 Honda Ridgeline vehicles. Recall 22V-867 states that the RVC wire harness was manufactured with a protective corrugated tubing which was insufficient to protect against bending wear and zip ties which 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 repeated opening and closing of the tailgate. This ultimately results in the failure of the RVC image to display due to a lack of connectivity. Honda’s remedy 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. On May 3, 2024, Honda submitted recall 24V-321 to ODI, addressing concerns of a loss of the RVC function in MY 2020-2024 Honda 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 RQ24011. To date, ODI has received 1 allegation of a 22V-867 remedy RVC wire harness failure. Honda indicated that it is aware of a total of 14 reports regarding remedy RVC wire harness failures associated with Recall 22V-867. Additional remedy parts may not have yet seen sufficient wear to induce the failure. ODI also believes further testing is necessary to assess the potential failures in these parts. This Engineering Analysis is being opened to further assess the scope, frequency, and potential safety related consequences of the rear view camera harness failures in 2017-2019 Honda Ridgeline vehicles.

On November 8, 2024, the Office of Defects Investigation (ODI) opened Recall Query RQ24013 to assess the scope of Honda recall 23V-751 after receiving complaints that alleged connecting rod bearing failures in vehicles that were not within the scope of recall 23V-751. In November 2023, Honda recalled 248,999 various Model Year (MY)2016–2020 Honda and Acura vehicles equipped with the 3.5L V6 engine. Honda recalled these vehicles due to a crankshaft manufacturing defect that caused premature connecting rod bearing wear and engine seizure. While the out-of-scope failures involved in these complaints appear to have a very similar failure mechanism as the recalled engines, a thorough analysis of all available data from Honda has not indicated that the same manufacturing defect exists in the out-of-scope engines as the engines recalled by 23V-751. Based on this analysis ODI has determined that Honda has properly defined the scope of recall 23V-751. Consequently, ODI will close this RQ investigation.  NHTSA will continue to investigate these complaints of engine failure as part of a new Preliminary Evaluation Investigation (PE25008). The Agency reserves the right to take additional action if warranted by new circumstances.

On February 7, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation (PE22-001) to assess alleged failures of the rear-view camera (RVC) in 2017-2018 Model Year Honda Ridgeline vehicles. At this time, ODI has received a total of 107 complaints with allegations of the RVC image failing to display when the vehicle was in reverse.The RVC wire harness is manufactured with a protective corrugated tubing and harness guide to help mitigate stress on the RVC wire harness when the tailgate was opened and closed. Honda determined the length of corrugated tubing inserted into the harness guide was insufficient to provide optimal protection for the wire harness. This lack of protection for RVC wire harness led to severe wire harness damage that ultimately led to the failure of the RVC image to display due to a lack of connectivity.On November 23, 2022, Honda filed a defect information report recalling all 2017-2019MY Honda Ridgeline vehicles. The dealer will replace the RVC tailgate harness with an improved wire harness that has longer corrugated tubing to protect the wire harness.In view of the recall action being taken by Honda, 22V-867, ODI is closing this Preliminary Evaluation. NHTSA reserves the right to take additional action if warranted by future circumstances.
