After a 2 1/2 drive (interstate, 75 mph on cruise contral, eco button not on), I took the exit to go home. Immediately after going from cruise to normal driving, the check engine light flashed and as I pushed down on the accelerator there was no power. The engine would rev up to 4000 rpm but would not go over 30 mph and would not shift. Once I got on the more level area of the road I did nurse it back to 55 but still very little power and the engine was struggling. I then stopped at a stop light and the engine shuddered when i tried to accelerate again, no power. Made it to a gas station, turned off the vehicle, filled the tank, then restarted, the engine ran just fine. Took it to the Honda dealership the same day and they were unable to find any codes on the computer and were unable to re-simulate what happened to the engine.
The auto high beams do not work with any consistency. They don't come when they should or will turn off because of a reflection from a road sign. Sometimes, they will activate right before a car passes you which causes that driver to flash me and now we both can't see! I can't believe Honda would allow this poor excuse of a feat…

I was driving 2 hours on highway trip (65mph) using cruise control. (20 degrees, light flurries, dry road, windy.) I then slowed to make left turn from the center turn lane. While beginning to cross oncoming lane while making the left turn, the vehicle suddenly lost power and check engine light started flashing. No prior warning to power loss. I barely cleared oncoming traffic, limped to shoulder, and parked. Problem was confirmed at dealership. The issue is known to Honda (also on past models). The dealer also confirmed there's still no fix/recall and that this typically happens in cold weather. The possibility of continued sudden power loss without a recall/repair is alarming and a serious safety issue. Service invoice stated: "Customer states the check engine light came on and power was lost. No DTC's were stored. Due to regional weather circumstances moisture will accumulate in the intake manifold. The water then will drain from the intake into the cylinders causing a misfire."
On more than one occasion, the Forward Collision Warning System and Emergency Braking System on my 2023 Honda Ridgeline activated when there was no obstacle. These incidents have occurred since new.

On more than one occasion, the Forward Collision Warning System and Emergency Braking System on my 2023 Honda Ridgeline activated when there was no obstacle. These incidents have occurred since new. Normally, the false activation causes my vehicle to flash the "brake" warning on the instrument cluster, the steering wheel to shake, and the brakes to be gently applied. However, one time a false activation occurred while I was turning within a busy intersection. This false activation caused my vehicle to suddenly brake to a complete stop. Thankfully there were no vehicles behind me.
The "auto dimmers" do not work. I have had it to the deal several times and they admit that Honda has a problem with them. They tell me they are working as designed and it is not the best design. The service team is now going to switch out vehicles with me to see if they are working 'as designed". The service team has told me t…

The "auto dimmers" do not work. I have had it to the deal several times and they admit that Honda has a problem with them. They tell me they are working as designed and it is not the best design. The service team is now going to switch out vehicles with me to see if they are working 'as designed". The service team has told me to just turn them off and do it manually. To me that is NOT the solution. But they were totally honest with me, telling me they do not work but not until after I purchased the Ridgeline. If I knew this I would have went to another manufacturer. Very disappointed in Honda. And equally disappointed in the service saying just turn them off.
Passenger airbag is indicated to remain on when no one is in the passenger seat. The airbag off light comes on during warning light check but then shuts off and remains off. I do not confidence that the accurate weight is being accounted for when a passenger is in the front seat.

I was on [XXX] and turned into [XXX] . I was driving at 25 miles or so. I don't know if my first or second tire flat first but immediately after my airbags at right and left front and back side got deployed and created a little fire and thick black smoke. I got shock, panicked and lost control for second and hit right front wheel trim of car to probably edge of road. I called Honda Road services to tow my car to nearest Honda services. They told me that a Tower would come over to take care of me in 120 minutes and take my car to Chantilly Honda services. Unfortunately they didn’t show up for 3 hours. I stayed outside in cold weather for 3 hours. Thankfully Police came over and saw the situation and he was really surprised with defectiveness of my car airbags. so He had to call Tow company that works for Police department to get my car to the nearest Honda services. I called Landmark Honda and told them the situation. Landmark Honda wanted me to bring my car to Landmark Alexandria instead of nearest Honda services in Chantilly. I towed my Truck to Alexandria. I paid for towing although they were supposed to pay. I talked to Honda headquarter in California but they didn't care about what i said. I could die lose my limbs or hurt other people. I am a Home improvement Contractor. I had to postpone my appointments with my new clients since then. i have no car and I have been losing business. I kindly ask you to help me with this issue. Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2023 RLT, about 1300 miles on the odometer, temperature was between 4 and 7 degrees F, it was a sunny day with clear roads. I drop 68mph for 70 miles, stopped to make a left turn, and when accelerating through the turn, the blinking orange check engine light came on and the vehicle would not accelerate beyond about 35 mph. I was towed to the nearest dealership from the location of the incident, which occurred over 400 miles from my home. It could have been fatal if there was traffic I had to merge with at the time when the engine was not allowing enough power. It happened at noon in a very small town in North Dakota. It could also have been fatal if it had happened in an area with no cell service and no traffic to stop and help as well. Thank goodness I didn't have any children with me and there was somewhere warm to wait the 2 hours for the tow truck. I found an online Honda Ridgeline owners forum where many, many people have reported this same issue: cold temperatures, going highway speeds for a certain amount of time, slowing down or stopping, and then trying to speed up to highway speeds again when the check engine light comes on and the engine limps. The Honda dealership where my vehicle was towed confirmed that I was subject to this "very rare glitch" that they know about and say there is nothing they can do to fix it and no assurances that it won't happen again. I'm not sure how to regain trust in a brand new pickup that I know has this issue that I have experienced first hand in the cold and could experience again that might result in a fatal outcome if Honda doesn't fix this known issue.

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy.

PE24004 · Rear-View Camera Failure
Opened Feb 13, 2024 · Closed Aug 5, 2024
Status: closed (inferred from source dates) · Back Over Prevention
On February 13, 2024, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE24004 to assess alleged failures of the rear-view camera (RVC) in 2020-2023 Model Year (MY) Honda Ridgeline vehicles. At this time, ODI has received a total of 50 complaints with allegations of the RVC image failing to display when the vehicle was in reverse. The RVC wire harness is routed near the hinge in the tailgate, in a location where frequent opening and closing of the tailgate causes bending stress on the harness. Honda determined the wire harness was manufactured with a material which is permeable to water and salt, which when it freezes and thaws, combined with tailgate usage, ultimately leads to breakage of the wiring in the tailgate harness. This results in a failure to display the RVC image. On May 9, 2024, Honda filed a Part 573 Safety Recall Report recalling all 2020-2024 MY Honda Ridgeline vehicles. The dealer will replace the RVC tailgate harness with a wire harness that is manufactured by a new supplier and has improved material properties to withstand wear from bending.
