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.

Engine suffered internal mechanical failure. I had the failed engine replaced so it is no longer in my position. My wife was driving and was nearly rear-ended on a major highway at around 55mph. Without warning, the truck stalled then completely stopped. she was able to get it running for a short period in order to go down an off ramp. Then it would not restart. I had the truck towed to the dealer and the diagnosing mechanic described it as an internal mechanical failure, most likely a rod bearing failure. The dealership service manager discouraged me for having the engine full diagnosed because of the cost. Failure occurred without warning. Once the truck stalled, all warning lights began to flash.

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.

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.

Beginning at ~30K miles, I am hearing a "rod-knock" from the bottom of engine. Especially noticeable when starting out from a stop. Easily reproduced by putting foot on brake, truck in drive, and slowly depressing accelerator pedal. All maintenance since day 1 on truck (now has 65k miles) has been done at dealer. Reported issue to dealer and they responded, "cannot duplicate". I fall within the Honda engine rod bearing issue and I am concerned about engine failure.

I am writing to bring to your attention a significant issue I have encountered with my 2019 Honda Ridgeline, which recently suffered a catastrophic engine failure from a seized connecting rod bearing, resulting in a blown engine. With virtually no warning, the dash lights illuminated and the engine lost power and started smoking while on the freeway. A 911 was called and police and fire responded. The engine compartment was drenched with water in an effort to prevent a fire. Any delay in emergency services response would have certainly resulted in a fire and possible accident or injury. The vehicle was towed to and is currently at my local Honda dealer who confirmed the cause of the engine failure. I was informed that there was a recall issued for this exact problem for 2017 and 2019 Honda Ridgelines, however my VIN was not included in the recall even though my vehicle experienced the same engine problems. Allstate insurance inspected the vehicle and confirmed the cause of the failure. Additionally, after researching this issue I found that there are numerous 2017 and 2019 Honda Ridgeline owners who have also experienced the same exact issues. I would like to understand why my vehicle was not included in this recall and if there is anything that the NHTSA can do to get it covered. I was told by Honda America that you have the authority to expand the recall..

I have a well maintained 2019 RIdgeline that at midnight on the highway started flashing a red motor sign at me, and within 10 miles was flashing all lights and chugging and grinding, stranding me. I found out Honda had recalled hundreds of thousands of cars due to a similar failure. I asked Honda customer service and my local dealer if I were to pay for diagnosis and it was the same failure as recalled motors, would they cover it, they won't answer me, but the dealer implies that I will pay all costs period, diagnostic fee as well as used motor cost, because even thought they quoted me a new motor at $20,000 they actually don't have the motor, so I have to take used motor. I went through a nightmare last year with them and had to pay $4000 for a torque converter repair while 2 1/2 yrs of my same truck got theirs free, mine was too newly built to be covered. I think they are borderline criminal in their actions.

i was driving abut 25 miles per hour on [XXX]. i split second my car start shake and rapidly stop. All electronic messages were displayed. My all safety fixtures stop working included air bags. I almost hit other car. Other cars start honk on me. i was able to move slowly to dealer about 5 miles per hour. distance was only half of mile. After diagnostic i was inform my crankshaft is bad. i received bill for $3832.57 $. i contacted Honda with concern about this safety problem specially i learned from dealer mechanic there is ongoing problem with this engine on Pilots Ridgelines and Odysseys models. Honda opened case Case #: [XXX]. i had safety concerns specially i was towing boat few days before. On highway speeds this could have catastrophic consequences for me my family and other people. i offered Honda old parts for investigation and determination of root cost of this problem. Honda wasn't interested this at all. They was interested how many times i serviced vehicle in this dealer. Honda knew about this ongoing problem. What I'm looking for is safety recall on this dangers issue and reimbursement for my expects. Thank You INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My car was recalled months ago but Honda has not provided the parts for the repair. I don't know why they are telling me about the recall (it is serious...fuel pump) but not getting parts in a timely manner to fix it. They keep telling me to call the dealer; the dealer keeps telling me they don't have the parts and there is no ETA as to when they will be available. Can't Honda just replace the entire fuel pump if they can not make or obtain the parts to repair it?

- Morristown, NJ, USA

I contacted North America Honda and they referred me to a local dealer. However, the dealer told me that they cannot repair the fuel pump until it breaks down on the road. According to a report, if the fuel pump malfunctions, it could shut off the fuel supply, which would cause the engine to stop running. As a result, you would lose power steering and it could create a hazardous situation while driving.

I have been to my Honda dealership four times for transmission issues and on the fourth trip to the dealer they were finally able to confirm the problem. My 2019 Ridgeline will kick/buck at about 27 miles per hour and will not shift into higher gears as I gain speed. When this occurs, my engine will operate at 4,000 RPM on the highway. There warning lamps when the transmission starts acting up. The some or all of the lamps will stay on for on or several days at a time and these include: Emission Systems Problem, Transmission Systems Problem and Blind Spot Info System Problem. My safety is at risk due to the fact the transmission does not shift and bucks and I cannot potentially accelerate in a normal manner which could lead to an accident. They have diagnosed the problem based on a computer code from the car to the service department. They say the part is on backorder and they do not know when it will be available. Could be up to six months. I have looked on the internet and have found many Ridgeline owners complaining of the same issue for the 2017-2019 model years. When I brought the car in for service the first two times I was under extended warranty and now they say I may not be covered because they could not detect it. I guess mechanics now rely on computers and do not accept the work of the owner as to the problems being experienced. The problem is the Pressure Control Valve Code # P0776

The 2019 Honda Ridgeline truck was driving at 70MPH for one hour at 25F temperature. After exiting the ramp, the Check Engine Light started flashing, lost power and the engine was running very rough and cannot drive more than 35MPH. Stopped on the side of the road, turned the engine off and then back on and the truck was driveable again. Had this truck for 4 years now and had this problem once or twice every winter.

Fuel / combustion chamber odors accumulating around engine compartment when vehicle is parked in garage and filling the cabin with nauseating odor. This problem comes and goes with new resolution from dealer. Seem as an engine venting issue. Ongoing problem since new phurchase.

- New Berlin, WI, USA

Smell of fuel or burnt oil emanating from engine compartment and entering cabin through HVAC system when idling. Warm engine also emanates fuel/burnt oil smell after it is parked and shut off. When parked in an enclosed garage the smell can be overwhelming. Took to the dealer for inspection but they claim they can not duplicate the issue. When researching online indications are it may be a leaking PCV hose that is allowing fumes to permeate. The situation is ongoing and frequently noticeable both in the cabin and outside the vehicle.
