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).

The auto idle stop system in the truck has become an issue with the vehicle stalling out (sometimes) when I hold the brake pedal. I have to then put the car into park to restart the engine. This has been a safety issue when I'm driving in heavy traffic and the truck stalls and I can't move forward with the other vehicles. I have taken my truck to the Honda dealer and they could not reproduce the issue at that time. They inspected the vehicle, confirmed the battery is fine, etc. They did mention the vehicle seemed slow to start. I have experienced this as well. At this time, Honda says there is nothing they can do to help me. My truck is only a year old and still under warranty. But this is a serious safety issue and I've experienced some frightening conditions on the road because of it.

Engine self destructed while driving on the highway. Lot of smoke and the car came to a stop pretty quickly. Oil and coolant dumped out of the bottom.

Driving approximately 15mph on a gravel road in my subdivision I noticed smoke or steam coming from under the hood. The time was approximately 30 am on June 4,2026 the 2023 Honda Ridgeline with 41,000 miles was immediately stopped and put in park. I exited the vehicle and started to open the hood and fire streamed out from the front of the vehicle. I backed up and went to the rear door and retrieved my dog from the back seat. The vehicle is a total loss as the fire spread incredibly fast. I’m lucky to be alive today. There were no warnings or messages.

I am reporting a recurring auto idle stop no-restart and starting-system failure in a 2024 Honda Ridgeline. At approximately 35,072 miles, while stopped at a traffic light with auto idle stop engaged, the engine shut off but failed to restart when the brake pedal was released. The vehicle remained disabled in the intersection until it was manually restarted, creating a risk of a collision. An authorized Honda dealer found both positive and negative battery terminals loose, tightened them, reported that the battery passed a load test, found no diagnostic trouble codes, and returned the vehicle. The battery had already been replaced at approximately 30,238 miles after a slow-start complaint and a failed battery test. The condition recurred at approximately 42,563 miles. After the engine shut off at a light, the vehicle displayed an orange “p” and “system problem detected - shift to park,” went into neutral, and required a manual restart before drive could be restored. The dealer later reported that the replacement battery tested at approximately 197 cca against its 650 cca rating, but no root cause for the rapid deterioration or the shutdown/no-restart condition has been identified. The vehicle now intermittently cranks slowly and appears strained while starting. No permanent repair has been completed. The vehicle is available for inspection. The condition creates a safety risk because the vehicle can fail to restart or move from an intersection and may enter neutral unexpectedly.

My wife and I had decided to empty our storage unit, so on memorial day we began moving everything into the garage. After five or six trips Honda, I pulled the car up beside the RV and close to the house for what turned out to be the last load. I unloaded my bicycle and nearly everything else, leaving only a few small items, and then removed the massage table from the back seat. The engine was off this entire time. That was when I noticed smoke coming from the engine compartment. At first, I thought the radiator had overheated, so I tried to open the hood, but it was too hot. I went into the garage for gloves and a fire extinguisher and tried again, but still could not get it open. Realizing the situation was getting worse and that I could not stop it there, I jumped into the car and tried to start it. To my surprise, it started immediately, and I drove it as fast as I could out to the street in front of the house. Only later did I realize that this likely saved my RV—and possibly the front of my house as well—from catching fire. We were so blessed that I was able to move the car to a safer location and no one was hurt. It was a miracle.

On two separate instances in the past month, I have come to a complete stop, and the engine automatically shuts off. Upon restarting it either failed to restart the engine or on this last occurence turned the engine over once, made the car lurch and took a few seconds for the engine to idle, almost as if the engine wasn't fully started and the starting motor kicked off as well as turned over slowly. The vehicle has 24,000miles and the batery is approximatley 15 months old and oem.

The contact owns a 2023 Honda Ridgeline. The contact the contact stated he experienced knocking in the engine. The vehicle was taken to the dealer where it was diagnosed with an air compressor failure; however, the issue persisted. The contact also stated another issue is the rearview camera displayed a distorted image. The contact also experienced loss of steering control with the vehicle pulling to the right. Intermittently veering towards the contact associated the issues with NHTSA campaign numbers 24v321000 (back over prevention) and 24v184000 (steering) the vehicle was not diagnosed or repaired for these issues. The manufacturer was notified of the issue. The approximate failure mileage was 32,000.

Camshaft failure, component not available for inspection. It was replaced at dealer. If this had failed on the highway at highway speeds it could have resulted in a serious accident. This issue was diagnosed and repaired at a dealership. There were numerous warning lights that came on. That is what alerted that there was a problem. Camshaft failure at 51,350 miles. . Premature failure of camshaft was wobbling and caused the failure of other engine components including camshaft, camshaft sensor, timing belt, timing belt tensioner, water pump, and other components, seals, and gaskets. Repair total was over 2,600.

While stopped in heavy traffic at a traffic signal, the engine stopped and would not restart. This was due to the ais system. The car became disabled in heavy traffic. I was only a few feet from the entrance to a gas station, however due to the interlock system that locks the transmission in park, the truck could not be pushed out of traffic. Honda, unlike other manufacturers the use the same transmission, does not supply an emergency over ride to get the transmission out of park ( hazard). After a few minutes of sitting in heavy traffic and nearly. Wing hit by fast moving cars, the engine did restart. This is not the first time this has happened. The dealership is over 100 miles drive to have to checked (r/t).

While operating my 2019 Honda Ridgeline at normal driving speed, the vehicle experienced a sudden and catastrophic engine failure without warning. Immediately prior to failure, a loud metallic knocking/hammering noise developed from the engine area. Within seconds, the engine lost power and shut off completely while the vehicle was in motion. After the shutdown, the vehicle would not restart. Attempts to start the engine resulted in minimal or no crank, even when using a jump start. The vehicle had to be towed. A subsequent inspection determined that the engine had no compression, indicating severe internal mechanical failure. The failure occurred abruptly and without any prior warning lights, temperature issues, or drivability concerns. This failure created a significant safety hazard, as the vehicle lost all power while driving, which could have resulted in a loss of control or increased risk of collision, especially in higher-speed or traffic conditions.

I had been hearing a ticking or clicking sound from the engine. When I brought it to a Honda dealership that I had used about a year ago for the 100,000 mile maintenance, I was told that the truck had a rod bearing failure and that I needed a new engine. I was told that if I kept driving it as is, that I could have catastrophic engine seizure without warning at anytime. This is a disaster waiting to happen. I saw that the same part on both the Ridgeline models of 2017 and 2019 had been recalled in 2023. The truck only has 110k miles and I have faithfully had routine maintenance. For an expensive $9,500 engine to fail at only 110,000 miles is not right. I will try to upload a picture of the invoice in a separate email. I hope this information will be part of the second investigation of the initial recall and also the present lawsuit against Honda in the state of California, thus sufficing as more evidence that the 2018 Ridgeline should be included in a second recall.

Engine seized while driving on the highway. Diagnosed to be a failed rod bearing leading to catastrophic engine failure. Vehicle and engine have 84,000 miles. I have owned and driven it since new.

The transmision failed with 120,000 miles, code p0776 "solenoid b performance/stuck off, vehicle goes into limp mode and it shifts really hard but never goes past 3rd gear, the recomended fixes by the shop are replace solenoid pack whith no garantee that it would fix the issue for $3,000, or replace transmision with a rebuilt one for $9,000. There is a recall for the torque converter on this trucks but it has to generate a different code. Honda will not honor any warranty on this vehicle.

The car engine stalled on highway and was not able to stall. Mechanic shop checked the car, and told me that the problem is a seized engine.

Catastrophic engine failure. Reported to NHTSA on 10. 11. 24 for recall 23. 097. Investigation (rq24013) which no issues were allegedly determined. Now a new investigation has opened pe25008: we had our engine replaced for a used one and are concerned that this engine still has the issues realated to recall 23. 097. Called Honda to ask if they can confirm whether or not this used/salvaged engine had been checked to see if it has rod bearing issues related to recall 23. 097 or was from a vehicle that was related to the recall. They said they had not. Furthermore, we provided the motor serial number so they can check and they said they were not able to. They have systems in place to quickly cross reference VIN and motor serial numbers, so it was surprising they would not be able to provide this information. Furthermore, why would Honda not have systems in place to ensure they are not installing a faulty motor given the absurdly expensive pricing for a used unit. Our families life was at risk previously with the first engine failure and now it could be again, and this was their response.

The dealership has advised replacing the transmission at a cost of $11,937. 77 following diagnostic code p0776 (a/t clutch pressure control solenoid valve b stuck off). I believe this expense should not fall entirely on me for the following reasons: • Honda has a documented history of transmission and torque?converter?related issues on the 2017–2019 Ridgeline. Honda service bulletin 23?078 extends warranty coverage to 8 years/150,000 miles for torque?converter failures associated with dtc p0741. My vehicle has previously undergone multiple transmission?related warranty repairs and software updates intended to address judder, slipping, and torque?converter concerns (referenced in earlier service records at 39,678 miles and during warranty-extension procedures). • my service history shows consistent dealer maintenance and multiple prior transmission?related interventions. The attached service records reflect that I have followed Honda’s recommended maintenance schedule and have repeatedly brought the vehicle to Honda dealerships for all inspections, fluid services, and software updates. The dealership has also previously documented transmission judder and performed warranty-related atf flushes and software updates intended to correct torque?converter and clutch?pressure issues. • the current failure appears related to long?term degradation of the same transmission systems Honda has acknowledged as problematic. Although the stored dtc is p0776 rather than p0741, both faults relate to clutch?pressure control and hydraulic operation within the 6?speed automatic transmission. These problems are highly consistent with the known failures described in Honda’s own bulletin and with my vehicle’s earlier symptoms recorded by Honda technicians—specifically hard shifting, juddering, and slipping under load. • a nearly $12,000 repair on a well?maintained Honda with documented history of related issues is unreasonable for the customer to absorb entirely.

Truck only has 40,500 miles. Was driving down road and made a clunk noise and engine seized up and wouldn't start. There were no warning signs. I had it towed to Honda dealership. Their official repair estimate states verbatim "bearing on a connecting rod went bad and the rod snapped. " the bill is $7800 for a remanufactured engine or $13500 for a new one. I had just had the vehicle's 40,000 mile inspection done at the same Honda dealership 2 months prior, and no issues were found.

I had went to the store which is about 3 minutes from my house and on the way back my truck started running hot all of a sudden we were almost home and it was boiling hot from the temperature gauge we pulled in we get out and we look and my vehicle is pouring antifreeze out so my partner looked and he thought it was the crush washer and bolt he replaced the crush washer we drove to morganton nc but it wasn't the engine actually had a hole in it and the antifreeze was pouring out of the engine there is a hole in it behind the drain plug there is no reason they should even be a hole in it I only have 64,000 miles on it it's been very well taken care of and I know that there is an investigation going on on these vehicles between 2017 to 2019 on the Honda Ridgelines I drive to working back I work the most 6 miles from my house text me not even 5 minutes to get to work and then I'll leave the office and it takes me about 5 more minutes to get to the place I'm going cuz I work with hospice but for my vehicle just to start overheating for no reason pull in the driveway moments later and there's a big hole in it there's something bad wrong and I need help with this I'm in healthcare and I have to have my vehicle I've not had this vehicle but about 2 years and I'm paying on it it's like it's corroded from the inside out I guess you could say!.

Driving home from work on a Friday about 1am and my engine started t knock and sputter and the engine light started flashing. Luckily I made it home. I let it sit for a minute and started it back up and it ran fine. I let it sit over the weekend I made an appointment the the dealership for the following Monday. On Monday it started fine to go to my dealer appointment but half way there every caution light imaginable came on and the info screen was scrolling failure of every system in the truck it seamed. Even the d for drive was flashing. It was knocking, sputtering with loss of power. Like it was in limp mode. Made it to the dealer and they said it was misfiring which caused the engine to come apart inside. 11k for a new engine or 8k for a used one with 46k miles. The truck only had 86,000 miles on it and has been always dealer maintained. We buy Hondas mostly for their reliability. Skeptical about buying another one.

The contact's boyfriend owns a 2019 Honda Ridgeline. The contact stated that while her boyfriend was driving at highway speeds, there was an abnormal banging sound coming from the vehicle. The vehicle entered limp mode with the check engine and emissions warning lights illuminated. The vehicle was pulled off to the shoulder of the highway and was later towed to the dealer. Upon inspecting the vehicle, the mechanic discovered that an engine rod had gone through the engine block, resulting in engine failure. The manufacturer was notified of the failure, and the contact was informed that there were no recalls or warranties on the vehicle. A case was filed with the dealer for financial assistance, but the case was denied. The vehicle was not repaired. The failure mileage was approximately 99,000.

After parking on the roadside with engine off for about 10 minutes, the truck would not start. I tried to start twice; the dash lights came on, I could hear the starter try to engage, felt a slight forward lurch from the vehicle, then nothing. The starter seemed to disengage' the dash lights stayed on, and the electric system went into acc mode. I tried twice with same result. I attempted to put the shift selector in neutral, but it stayed in park. I was seated in truck, seat belt on, foot pressing on brake pedal. After waiting a few minutes, it cranked and started normally. No further issues the rest of the day. The weather was mild, sunny, temperatures in the mid-60’s fahrenheit.

The contact owns a 2019 Honda Ridgeline. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. A diagnostic test revealed codes for the catalytic converter efficiency below threshold bank 2, and bank 2 air-fuel ratio imbalance. The vehicle was taken to a dealer, and the dealer referenced NHTSA id number: 10187289 (fuel system, gasoline); however, the VIN was not included. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 60,000.

Coming down a ramp in parking deck with right foot lightly riding the brake pedal to control the car’s descent when all of a sudden the vehicle accelerated full throttle as if the gas pedal had been “floored. ” the acceleration was so intense that it drove my body backward into my seat and pulled my foot off the brake. At this point, the only control I had was my hands on the steering wheel. With the car continuing to accelerate towards the parked cars, I quickly turned the steering wheel to the right, but too late and the front driver side of my vehicle clipped one of the parked cars. My foot is still in the air and yet the car is still surging ahead full throttle and my vehicle is flying towards a car that had come down the ramp a few seconds ahead of me. At this point I slam my right foot onto the brake pedal, but not in time to avoid the passenger front bumper of my vehicle from hitting the rear of that car. At this point, my vehicle’s engine shut off and the Hondalink automatically dialed for help.

75k miles on the engine, routine 5k oil change intervals, rod bearing failure.

The cel flashed 2 days earlier, I immediately pulled to the side of the road and turned the vehicle off, suspecting it may be a misfire. Restarted the vehicle and all seemed fine. After arriving home I plugged in my scanner to check for a code. No codes were found. I decided to carry my scanner in the vehicle, and plugged it in before starting a 10 mile drive to a store. After 3 miles, the cel flashed and displayed code p0303 cylinder 3 misfire. I pulled to the side of the busy interstate I was on and turned the vehicle off. When I restarted the engine, a heard a rattling sound and turned it off. I then called the dealer and asked me to have it towed in. The dealer diagnosed a cylinder #3 spun rod bearing. This occured at 68,517 odometer miles.

On 1/5/2026 while pulling unto a major intersection, my 2019 Honda Ridgeline with 64,000 miles suddenly jolted, lost engine power, and every dash light came on indicating that all electronics were inoperable. Fortunately there was no fast moving on coming traffic. After examination in mechanics shop, it was found that the camshaft was bad. Attached is the $3,900. 00 invoice. Attached also is a picture of the sensor showing that the camshaft was moving and hitting the sensor which caused the truck to go into safe mode. According to your own investigation and speaking to the Honda service department, this obvious is a factory defect that Honda needs to address. The cam obviously is not strong enough. There are 4. 3 million complaints. I want to be reimbursed or will never, ever buy a Honda product. This is a safety issue as well as a consumer protection issue.

Vehicle has stalled after being stopped at red light. Does not occur all the time. Only when in idle mode.

Total engine failure on 2017 Honda Ridgeline. It is available for inspection upon request at milton martin Honda, gainesville GA. On the highway going 65 mph when my truck lost power, started shaking and the engine started making loud scraping noises. The engine light then came on. Pulled off the highway slowly with flashers on. The first time turning the ignition back on, all the warning lights came on solid and the warning messages started cycling through. The second time turning the ignition on the engine light started flashing. I then had the truck towed to the Honda dealer I purchased it from. Their diagnosis is total engine failure and it needs the engine replaced. All recommended maintenance has been kept up to date on the vehicle. This engine failure is a huge safety risk and appears to be the same issue as in the earlier recall from November 2023 although my VIN is not one of the ones listed.

Driving down the highway road I lost full power and the engine made a bad knocking sound when the gas pedal was pressed. It is at the dealership they stated there was metal in the oil and stated the bearings wore out. No warning lights while driving. It has approximately 72,000 miles. I was able to control the vehicle, but could not drive it far. Going uphill it could not travel at the same speed as traffic. That put my safety at risk one, because it caused others to slow down, two I was in a remote part of the state by myself if it stopped altogether I would have been stranded.
