2017 Honda Ridgeline engine problems

“I own a 2017 Honda Ridgeline with the 3.5L V6. The vehicle developed a noticeable engine knocking noise along with a check-engine light. I took it to a Honda dealership for diagnosis. The dealer confirmed abnormally low oil pressure, reporting approximately 6–7 PSI at idle on Bank 2, and recommended complete engine replacement at an estimated cost of approximately $9,000. To my knowledge, the dealer has not identified the exact internal component causing the knocking noise or low oil pressure. The vehicle and engine are available for inspection. This vehicle has a significant prior engine-failure history. At approximately 102,851 miles, the previous engine suffered a spun No. 2 connecting-rod bearing, crankshaft/connecting-rod damage, and metal contamination in the oil system. That engine was replaced with a used engine, which is the engine currently installed. Before the current diagnosis, diagnostic code P2651 was present. The related oil-pressure switch and rocker-arm oil-control solenoid were replaced and the codes cleared, but the abnormal engine knocking remained. I am concerned this condition could result in engine seizure, stalling, or sudden loss of…”

“Dear National Highway Traffic Safety Administration, I am writing to formally report a serious safety concern involving my vehicle, which experienced a sudden engine shutdown while I was driving on the busy [XXX] toward the [XXX]. The engine unexpectedly stopped operating due to oil-related and engine issues, creating an extremely dangerous situation for me and potentially for other motorists traveling on the roadway. Having a vehicle suddenly lose engine power while traveling at highway speeds presents a significant safety hazard. The unexpected loss of power can leave a driver with limited ability to maneuver safely, increase the risk of a collision, and expose the driver and passengers to danger from surrounding traffic. In my situation, the engine failure occurred without warning while I was on a busy highway, placing my safety and the safety of others at risk. I am concerned that the circumstances surrounding this failure may indicate a potential safety-related defect involving the vehicle's engine or oil system. I respectfully request that NHTSA review this incident and determine whether similar complaints have been reported involving this vehicle, its…”

“Engine started running extremely rough, and multiple warning lights came on. Had to have it towed to a mechanic. This rod bearings failed, this is a Honda recall, but they refuse to honor it.”

“I own a 2017 Honda Ridgeline with approximately 128,000 miles. In late August 2026, I noticed a deep knocking noise coming from the engine shortly after an oil change. The knocking increased with engine RPM and continued even after the engine warmed up. The oil level appeared full, and there was no oil-pressure warning light. I brought the vehicle to Liberty Honda in Connecticut for diagnosis. Their technician investigated the noise, identified it as internal connecting-rod knock, and determined that the engine requires complete replacement. The dealership quoted approximately $19,210 plus tax for the repair. I have driven approximately 40,000 miles since purchasing this vehicle and have consistently maintained it. Oil changes were performed at Valvoline approximately every 3,000–5,000 miles using their premium oil service. Routine maintenance was performed by an independent mechanic, while major repairs were handled by Honda dealerships. The timing belt was serviced at approximately 84,000 miles. I am concerned because Honda previously recalled certain 2017 Ridgelines for connecting-rod-bearing defects, and NHTSA has separately investigated similar failures in…”

“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 contact owns a 2017 Honda Ridgeline. The contact stated that while driving at an undisclosed speed, the vehicle started shuddering and vibrating before becoming inoperable. The check engine warning light illuminated, and five seconds later the "Low Oil Pressure" warning light was illuminated. The vehicle was towed to the dealer and was diagnosed with a spun rod bearing and engine knock. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 152,000.”
