2017 Honda Ridgeline

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 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.

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 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. RQ24011 is being upgraded to an Engineering Analysis (EA25003) to further assess the scope, frequency, and potential safety related consequences of the Rear View Camera harness failures in 2017-2019 Honda Ridgeline vehicles.

connecting rod bearing (Recall 23V-751) failed in my 2017 Honda Ridgeline which was not part of the recall for this issue. Oil light came on and I took to my mechanic for service and on the way there i started to hear engine noise. As I pulled into mechanics shop he was outside and heard the noise. He told me that the car was getting ready to have catastrophic engine failure and was going to need a new engine. I was going to drive to the parking lot next door and leave the car to have it towed back to my house and it died as i was tuning into the lot. It was dangerous as it died where there was traffic passing by and i had to push the car out of traffic. The engine light came on Sunday, Monday (Labor Day)the car was not driven and then was taken to mechanic Tuesday morning.

The first time I was driving about 30 miles an hour. There was a car in front of me about 10 car lengths who put on his blinker to make a left turn. I started to tap my brakes to slow down. The car was so far in front of me that I didn’t even need to slow down, I was being careful. Suddenly the truck shuddered and stopped and BRAKE, BRAKE flashed on the screen in front of the steering wheel. Everything in the truck flew forward. The people in the vehicle behind me started blasting the horn because they almost rear ended me. My truck just slammed on the brakes for no reason. Another time I was driving down the interstate highway. There were no cars in front, behind or on either side of me. Suddenly, the truck shuddered and BRAKE, BRAKE flashed across the screen. I was driving about 70 miles an hour. The truck did not stop. It just shuddered and slowed down. Those were the two scariest times. The truck since then will flash BRAKE on occasion if I step on the brakes to start slowing down. I called customer service for American Honda and they told me to take it to a Honda dealer when it was happening.

Bought this vehicle in December 2025 used from a dealership. After about a month, I started hearing a noise coming from behind the steering wheel inside the dashboard area. Being that it was a new car to us. We weren’t sure if the noise was problematic so we didn’t take it in right away. The noise started getting worse after a few months and we brought it in. The mechanic couldn’t find the reason for the noise however did notice that there was metal in the oil and heard a knocking that was abnormal in the engine. After some investigation, we discovered that 2017 Honda Ridge lines were known for connecting rod, bearing failures, and many of the vehicles were under recall. We checked the VIN number of our vehicle and were told that this was not under this warranty. We called Honda Customer Care to talk to them about the fact that this problem seem to be the same problem as the service bulletin problem. We asked if they could cover the cost of the repair. They suggested we needed to have it diagnosed by a Honda dealership. We brought it to the Honda dealership who told told us that it would cost $1000 out-of-pocket to be able to diagnose this problem properly. We now have a car that potentially has a extremely dangerous and potentially catastrophic engine problem with premature deterioration and failure of the crankshaft connecting rod bearings that we are afraid to drive and we don’t have the money to fix. When doing research it suggests that there are at least 1.4 million vehicles that are under investigation for the possibility of having the problem that is addressed by the recall, and many of these vehicles are still having this engine failure and we think ours may be one of these. We have not seen any engine warning lights yet however, the mechanic suggested that it is premature crankshaft connecting rod bearing failure as evidenced by the amount of metals showing up in the oil. We just recently replaced the oil in early June (less than 2,000 miles ago).
