Honda Ridgeline check engine light comes on

Filed Oct 28, 2026 · Engine · OH

With no warning engine started making a loud ticking noise and within a couple of days it was a loud knocking noise. Flashing check engine light came on and engine lost power. Shut down and restarted engine, knocking noise still there but check engine light is not flashing. Knocking noise is loud and vehicle cannot be driven. Mileage is around 170000 but has had regular oil changes. Mechanic has confirmed the engine knock and said not to drive it. Can't afford to replace the engine.

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 power while driving. Because of the knocking noise and confirmed low oil pressure, I do not consider the vehicle safe to drive. I am aware the federal safety agency is investigating connecting-rod-bearing failures involving 2017–2019 Honda Ridgelines and other Honda/Acura vehicles. Given this vehicle's prior documented connecting-rod-bearing failure and its current knocking/low-oil-pressure condition, I am submitting this complaint so the federal safety agency can determine whether it may be related to the broader issue under investigation. The vehicle has been inspected by a Honda dealership, and I have contacted American Honda for assistance.

just got on the freeway when car lost power, slowed down, check engine light turns on, and more lights start flashing. Potentially could have caused an accident if I was going faster on road. Went to mechanic, Code P0301, after diagnosis, fuel injectors failing. Mechanic was able to reproduce incident. Similar to recall for previous models, but not recalled on 2022 model. Need to replace fuel injectors. Had minor loss of power a few days prior, but not as severe

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.

I have an engine failure at 99k miles. The car is in pristine condition inside out. Oil changes are done every 5k miles. Without any warning, check engine light or any indication from the car's computer, the engine just failed while driving. It sounded like there was something grinding inside the engine. The truck was towed to Honda dealer and they said I need a new engine replacement. They found metal shavings in the engine oil. The invoice indicates "Found more has bad rod knock recommend replace engine assembly"

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).
