Engine And Engine Cooling Problems of Honda Ridgeline - part 2

My check engine light started blinking, and the engine began to idle roughly. Took into dealership, and there was a connecting rod bearing failure on cylinder 1. Seems related to recall 23v-751.

Engine "stop/start" turned off when trying to make a turn. When it did the steering would not move. Also when "stop/start" turns off it was dangerous when turning. I email Honda and they called me back. They could have it disabled but it would cost $80 and I would have to buy the part and they would install it. This is a new truck bought last month.

After taking my 2017 Honda Ridgeline to first Honda in simi valley, CA for its 100,000-mile maintenance, including a brake service and an oil change, I experienced a major engine failure just two days later. I let my son drive the vehicle from simi valley to the east bay area for college. The next day, the vehicle broke down and had to be towed to hayward Honda. At hayward Honda, they informed me that the oil was extremely dark and looked like it had not been changed, despite being billed for it at first Honda. Furthermore, they diagnosed that the engine failure was due to a connecting rod bearing failure — the same issue currently under investigation by the NHTSA. This breakdown happened without warning right after scheduled maintenance and may indicate both negligence by the servicing dealer and a defect in the engine. I believe this incident should be included in the NHTSA investigation related to engine failures in 2017 Honda Ridgeline models.

The contact owns a 2017 Honda Ridgeline. The contact stated while driving at an undisclosed speed, several unknown warning lights were illuminated. The vehicle was taken to a dealer where it was diagnosed and determined that the connecting rods needed to be replaced. The contact researched and was made aware of NHTSA campaign number: 23v751000 (engine and engine cooling); however, the VIN was not included. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 107,000.

I was driving home climbing a hill in the slight rain when the check engine light came on. I drove with the light on to get to the next closest city about 2 minutes out from where the light came on. The engine was running rough and shaking the car and was having issues stopping at a light before I could pull into a parking lot. I pulled into the parking lot, my book said that it was a misfire and to let the engine cool off so I sat for about 2 hours, checked fluids then started the car. The ticking noise was there but there were no lights on my dash at the time and assumed it could make it home after I let it idle for 5 minutes. I proceeded to get on the road and the vehicle did ok. I got on the freeway to get home, slowly let the car climb to 50 and kept it there. 1 minute later the whole dash glowed saying everything was not working and giving special pop-ups on the dash explaining the vsa, abs, and electronic power steering were not working to name a few. I stopped the car and pulled over immediately and called for a tow. I took it to my local electric shop to see because the brakes still worked and they said that it was possibly the ecm, that they couldn't fix it, and the ticking was a heatshield, and to take it to the dealer. I then towed it to the dealer. The Honda techs said that they didn't know what was wrong because the car wasn't throwing any codes. They replaced the tailgate harness that the previous dealer I took it to didn't and said to replace the pully and tensioner before they drove and diagnosed it further. I had it towed to another shop to get those replaced. This shop listed some of the same fault codes as the first shop and when they tested the vehicle they had called me to come in and inspect the vehicle as they started it after it was at the dealer and told me it was an engine knock and that the engine would need to be replaced with the drive shaft. I called Honda's corporate office and they took my complaint and documented it only.

The automatic engine stop/start system is a safety hazard. On multiple occasions with two different drivers (husband and wife owners), the engine has stopped just as the accelerator is pressed after waiting for traffic to clear at a stop sign or while waiting to enter a street from a driveway or parking lot. The delay when expecting the vehicle to accelerate has nearly caused accident(s) several times. Drivers are forced to switch off the automatic stop/start system every time the vehicle is driven since it defaults to active and it is not safe to use. The system should be permanently disabled or at least programmed to be disabled as default when engine is started. This issue was reported to the local Honda dealer during the first routine service--owners were told that nothing could be done by the dealer. The service advisor suggested that we contact manufacturer or NHTSA directly. The incident date and mileage were entered below for yesterday since that was the latest event. It has happened numerous times since the vehicle was purchased in July 2024.

The autostart does not work. This has happened to me three times since I bought it brand new in April 2021. I have taken it to Honda for repairs and they did nothing as they could not replicate the issue. Just happened again on March 24th after driving 10 minutes on the highway.

Sunday March 23, 2025 vehicle would not restart after the auto engine idle shut off feature turned off the engine. Attempted to restart several time with no success. Vehicle finally did restart when jumped the battery. Could be a safety hazard being stuck in traffic. Have not reported to dealer but will on next scheduled service. No warning lamps indicated a problem but every lamp on the dash console lit up when attempting to restart.

We were traveling up the freeway just like any other day. Out of nowhere the low oil light flashed and next thing we know a loud clanking started to happen. We were able to make it to the exit as it was right there thankfully because once we stopped I shut the engine off got out and checked the oil and it was full. I tried to start it again, it started but turned it off fast because the noise it was making was horrible. I’ve contacted Honda regarding this issue because the Ridgeline from 2017 and 2019 are covered under a recall but the can’t explain why the 2018 is exempt from the recall seeing it’s the same engine.

2021 Honda Ridgeline sport with 60,000 miles and no other issues. Engine failed to restart after the "auto stop/start" kicked in, all the lights on the dashboard went off and then turned off. After 1 minute, I was able to get the car started again, this happened on 3 different occasions over a 4 week period. Got the car tested and the starter was bad. Contacted Honda, they said too bad, no issues with the starter. I got the starter replaced for $800 and now NHTSA is investigating the issue Honda said was not an issue.

As I was driving on the freeway, the vehicle lost power completely without any prior warning. All the lights on the dashboard were flashing. The vehicle could not be started again. I was stranded in the middle of the freeway at the very high risk of being rear ended given the relatively lighter traffic at 11pm in los angeles. It put other drivers on the freeway at very high risk of running into me as well. The vehicle was towed to the dealership where an inspection was conducted. It concluded a blown-out engine (literally), possibly caused by the piston. A hole was found on the engine cast. The incident was escalated to Honda's corporate customer care department.

On multiple occasions at highway speeds when coasting for a few seconds roughly 50mph to 70mph, the truck begins to stall/ lose power. We thought it was related to the auto-idle feature, but the last two events I had it turned off. This has happened 5 or 6 times to me and my wife since about six months after buying the truck. Four of the events - November 2023: [xxx] in new jersey at ~50 mph, engine lost power, applying gas did nothing. A few seconds later it regained power and made a buzzing noise. [xxx]: on [xxx] in virginia, going down hill at ~70 mph, the engine lost power without warning, steering & brake pedal began to freeze up as if the truck was turning off when coasting briefly down with the flow of traffic. I pumped the gas pedal to no avail - a couple of seconds later it recovered and started up - and buzzed loudly. I avoided an accident; luckily the vehicle behind us was not tailgating. No lights or warning appeared on the dash. The dealer scanned the truck's computer and they noted a transmission event code, but nothing more. Could not replicate the issue. [xxx], jacksonville, FL [xxx] near [xxx] at ~62 mph, in the middle lane with auto-idle turned off, engine began to lose power briefly with a slight buzz (high pitch) when it "came back" to full power - again while cruising, almost coasting - to keep pace and distance from the vehicle in front of me. My wife witnessed the event and made note of the time and speed. [xxx], 8:13pm - on [xxx] going through jax on the way to the airport to pick up my wife. In the middle lane (second over from left lane) at ~60mph started to lose power in spite of my foot being on the gas. I kept the gas applied and the engine power came back. No buzz sound. At ~ 31,531 mile on the odometer. The truck has been back to the dealer 3 times and they cannot replicate the event. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The truck has had ~6 occurrences since purchased where the engine briefly loses power in highway cruising speeds between ~50 and 75mph at first we thought it was a safety feature or governor on the truck – or a malfunctioning of the auto-idle. I mentioned the incidents to the dealer service techs where we bought it but there was no awareness or acknowledgement of issues or a safety feature that would do this. This has happened to both my wife and me when driving; we began documenting the events - the last 3 are as follows: [xxx], midday. [xxx], va, going downhill at ~70 mph, engine began stalling without warning when I eased off the gas to coast briefly downhill in the flow of traffic; steering and brake pedal began to freeze. I gave it gas, pumping the pedal to no immediate effect; a couple of seconds later it recovered and started up; making a loud buzzing noise. I avoided an accident in traffic by not panicking and because the vehicle behind us was not tailgating. [xxx], 7:08 pm. I [xxx] at ~62-65 mph, again in the middle lane cruising with traffic, auto-idle turned off. When we coasted for a few seconds in the flow, the engine suddenly lost power; would not accelerate or re-engage. After a couple of seconds the engine came back to full power with a slight buzz (high pitch) – not as loud as previous times. [xxx]/ 8:13 pm. On [xxx] going through jacksonville downtown on the way to the airport. In the middle lane (second over from left lane) at ~60mph the engine started to lose power in spite of my foot being on the gas. I kept the gas applied and the engine power came back. No buzz sound. At ~ 31,531 mile on the odometer. Note that we changed dealers for the service – Honda of the avenues, and they have had the truck a few times since the [xxx] event. They have been able to pick up one code when scanning the truck – for a “transmission event. ” they cannot replicate the event.

The contact owns a 2019 Honda Ridgeline. The contact stated that there was a rattling sound coming from the front end of the vehicle near the fuel injectors. There were no warning lights. The dealer was contacted, and an appointment was scheduled. The vehicle was not yet diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was 104,000.

My engine started to have a clicking or a ticking sound, and then abruptly stop running. The dealer said that the engine is seized up. From what I have read, it sounds like the connecting rod problem that other 2017 models have had. I think that my engine needs to also be on the recall. Honda has offered no help with this, what-so-ever, even though I think they know there is a manufacturing defect.

I started getting a p0306 code on my truck on Thursday Jan 2, 2025. I took it to my mechanic and he said that it is a lower engine problem. On Saturday Jan 11,2025 there was a loud clunk from the engine and the vehicle lost power. My mechanic said that the connector rod broke. I contacted Honda but they said my VIN is not in the recall and I would have to deal with the dealership. I know that they won't do anything so I am in the process of trying to install a used engine myself.

Checked oil display at 40% on 04jan2025, had to put in 2. 5 qts 0-40 viscosity engine oil to get between bottom and top level markers on the oil dipstick. On 08an2025 at approx 4:35am, on the way home, heard engine noise (like 2-spoons tapping together) and within 1-minute the engine died and will not start, just a click. Had the vehicle towed to my residence (approx . 5 mile) and parked for 3-weeks to check if battery, bad gas, and/or transmission neutral safety is/are the issue(s). Finally got the vehicle towed to a local shop on 29jan2025. Called local shop on 31jan2025 and informed that there is no oil in the engine, and recommended to replace the engine. Note: oil/filter changed on may2024, and have purchased oil/filter on 07jan2025 to change oil as soon as the oil displays 30%.

After significant time (hours) at highway speeds with 90% cruise control use, the car, when stopped at exit intersection, goes to fractional power with the engine light flashing. The car can still move haltingly at approximately 5 mph. Once safety stopped and shut-off, car will restart without any check engine light and will function normally. This has happened on multiple occasions, in both hot and cold weather. When mentioned to the dealer 2 years ago, said they had never heard of the problem. Internet forums show mine is not an isolated instance. When the car fails, it is in an intersection, where cars coming from all sides are not expecting a car to limp through at 5mph. This is a safety to issue to anyone on the road at the time.

After performing regular maintenance to Honda Ridgeline 2018 by replacing the spark plugs, spark plug number 4 was contaminated with oil. All other 5 spark plugs had not sign of oil. This was discovered during the 100k miles tune up. A leaking component (e. G. A tube seal) in the well or an engine-related issue that's causing oil to enter the combustion chamber can cause a critical engine failure.

Vehicle goes into limp mode, limited power, flashing check engine light this happens after extended period on highway (hour or more) below 20 degrees f. When you exit highway and come to a stop. All good as soon as you try to accelerate cel starts flashing and I have reduced power. To correct this. The vehicle has to be shut off and restarted. This means it happens when pulling out into traffic from a stand still at a stop light stop sign. Limited to about 15 mph regardless of road pulling onto. Then have to pull over shut off and restart put back in drive and go. This is not ideal in most cases and dangerous. Honda released a TSB but will not cover if out of warranty. I filed case with Honda at 70 k. They agreed to pay for parts and labor minus $50 deductible and sales tax on parts. This affect all 2017 to 2023 and some 2024 vehicles with 3. 5l engine. This first happened to me with roughly 2k miles on car and is sporadic. Only cold weather and matches their TSB. Happens frequently every winter for me. For last 3 years when I found Honda TSB 24-085 suddenly the dealer knew this was happening. Yet I have been complaining for 3 years of issue. Once I showed them TSB suddenly OH that’s what you mean.

Crankshaft leading to rod bearing failure causing engine failure. Same issuse as 2017 and 2019 models that had recall 23v-751 issued.

Multiple instances of emission system warning/stop start failure warning alerts. Warning lights will randomly go off then back on. Replaced sensor and it failed within a month. Truck has under 21000 miles.

The contact owns a 2022 Honda Ridgeline. The contact stated while driving at an undisclosed speed, the engine was abnormally loud before the vehicle lost motive power. The contact stated that the sound was extremely loud, like the rod bearings were banging together. Additionally, several unknown warning lights were illuminated. The vehicle was driven to the shoulder of the road. The vehicle was then towed to the dealer where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 50,150.

Connecting rod bearing on the #6 cylinder. . . After the injectors failed and the vehicle was barely drivable the Honda mechanic heard a knocking in the motor which was confirmed when I agreed to pay $700 for them to tear it down to look. Mechanic confirmed issue which is exactly same issue as the recall for other 2017 Ridgelines. I am somewhat lucky as I had purchased an extended warranty but it will still cost me over $700 to get a used motor. The insurance company confirmed issue. There were no warning lights or anything that came on prior to the injectors failing. Could have been a major issue as mechanic said it was just a matter of time before motor completely blew up.

I have had an engine knocking noise at startup but now is continuous/constant. Diagnosed at my local Honda dealer as a connecting rod failure of my well maintained 2020 Honda Ridgeline. Recommended repair, short block replacement or engine replacement with a used engine. My 2020 Honda Ridgeline is not part of the safety recall for the connecting rod bearing recall and should be. I have read numerous stories of owners with Honda Ridgelines and pilots that are outside the recall years with this failure.

2022 Ridgeline's auto idle engine off/on activated while driving/moving. This week it occurred (Wednesday, Dec. 4, 2024) on i95 in virginia when going down hill at approximately 70 mph. The engine ceased without warning and the steering and brake pedal began to freeze up when I had eased off the gas to coast briefly down hill (in order to keep in the flow of traffic). I then gave it gas, pumping the pedal, and a couple of seconds later it recovered and started up; the truck’s starter buzzed loudly as it restarted. I avoided an accident in traffic by not panicking and luckily because the vehicle behind us was not tailgating and that the section of highway was straight and not on a bend - otherwise it could have been catastrophic. The rest of the trip we turned the feature off and the truck had no incidents. Based on the few previous events, which were at slower speeds, it seems that if the truck coasts even briefly the feature can trigger as if the sensor "senses" that the truck is not moving - and the engine turns off (previously it felt like the truck was stalling). I previously mentioned the incidents to the dealer service techs but there is no awareness or acknowledgement of the issue. This week I placed another call to the dealer and left a detailed message - but nobody at the dealer has acknowledged this is an issue.

I have a 2021 Honda Ridgeline. It had a 3. 5 liter v-6 with a 9 speed transmission. I was driving from cincinnati to cleveland on [xxx] Sunday [xxx]. It was about 25 degrees fahrenheit outside and partly cloudy. After driving about 3 1/2 hours I exited the [xxx] and turned on to [xxx]. The on- ramp is a sharp right turn so you have to slow to around 25 mph or slower. When I gave my Honda gas to speed up to merge onto [xxx], the vehicle started shaking and the check engine light began to blink and the truck was almost unresponsive and went into "limp" mode only using 2 or 3 cylinders and roughly shaking as I tried to accelerate. I pulled off to the side of the shoulder on the interstate, put my hazard lights on and drove to a nearby Honda dealer (about 3 miles away). It was a Sunday so the service department was not open. My family and I got a ride home and I began researching this issue in on-line forums and other Honda on-line threads. What I saw was a lot of people are having this exact problem with their Honda v6 vehicles. Story after story I read of this same situation that had just happened to me. 1. Long drives of 1 hour or longer 2. Highway speeds 60-80 mph 3. Cold weather usually below 32 degrees f 4. Slowing down off the highway then making a turn 5. Accelerating after turn then the vehicle goes into "limp" mode shaking, check engine light blinking, and vehicle is unresponsive or very weak some of the owners were in canada and some in united states but they all had the same situation that I had. In the Honda Ridgeline forums they took it to their dealers and most of the dealers said it was bad gas so when I called my dealer the next morning and that is what they said I was very skeptical and told about what I had read on-line, that this was a common problem and they said there was nothing they or Honda could do about it. The end result was a $1,700 bill. (I have a copy) please look into this. Thanks. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Unknown, engine bearings.

The contact owns a 2021 Honda Ridgeline. The contact stated that while driving approximately 30 mph, there was a knocking sound coming from the engine compartment while accelerating and there was a loud popping sound coming from the engine compartment shortly afterwards. The low oil level warning light was illuminated. The vehicle was towed to firestone and was diagnosed with engine failure. The vehicle had not been repaired by firestone but was instead towed to the dealer. The vehicle was diagnosed, and the contact was informed that the connecting rods had disconnected, causing engine failure. The contact was informed that the engine needed to be replaced. The dealer informed the contact that the repair was not covered under warranty due to the low oil levels. The contact confirmed that the low oil level warning light occurred during the failure. The vehicle had not been repaired. The manufacturer was made aware of the failure and opened a case regarding the failure. The failure mileage was 52,000.

Excessive wear on connecting rod or crankshaft bearings. While performing a pre-road trip oil change after only 1600 miles, I found a large amount of copper glitter metal particles in the engine oil. I have oil samples and the oil filter available for inspection. And I have pictures. If the bearings seize the engine will stop running possibly causing an accident. I had put just 15 miles on the fresh oil while driving it to the Honda dealer. They drained the fresh oil and said they did not find metal - not surprising because I had just changed it. They said the connecting rods weren't knocking and to drive it another 5000 miles then bring it back. I hear some faint knocking when the engine is cold that goes away as the engine gets warm.

Have taken in a few times for engine knocking, Honda has down oil changes and reported noise is normal but is getting louder, purchased extended warranty from Honda dealer. Also had at Honda for oil and filter change a month ago, they also were supposed to have completed the tailgate harness but told me it had be previously complied with but never took it off the list of open recalls. Honda isn’t the company it used to be. After my purchase of my new Honda pilot and issues- it will be my last Honda period.

Was extended warranty for my make model and year for faulty fuel injectors. Exact same codes on the bulletin but wasn't covered due to VIN specific.

Engine push rod on recall lists.

The drive train / transmission has always had a "pause" then a "clunk" before shifting into or from reverse gear, its worse now. The engine is starting to make noises and im afraid its part of the engine recall of 2017 and it may fail and injury me while driving. I take excellent care of my truck and its only adult driven by me, hence the concern.

Vehicle is currently at curry Honda in yorktown NY awaiting an engine repair. The vehicle developed a rod knock consistent with nhsta campaign number 23v751000, engine damage from connecting rod bearing wear. Metal shavings were in both the engine oil and oil filter as confirmed by technicians at curry Honda. Vehicle was driven to the dealership and all mechanical issues were verified by dealership employees.
