The auto idle function- the car engine doesn't restart. This has happened in a busy intersection and won't restart until you have made several attempts to restart. I have brought this to the attention of Honda certified techs.

FORWARD COLLISION AVOIDANCE 2026-08-23 · NHTSA 11758843

The complete Advanced Driver Assistance Systems (ADAS) has been disabled on my truck and all the warning lights are on. All the safety features ment to keep me safe on the road are no longer working.

SUSPENSION,WHEELS 2026-08-22 · NHTSA 11758791

1.The rear wheel assembly, lug nuts, and potentially the wheel studs/rear suspension system failed due to improper torque and installation by the dealership. Yes, the vehicle components are available for inspection 2.The dealership released my vehicle with completely untorqued lug nuts on the rear wheel assembly. A lug nut physically fell off onto the public street while driving back to the shop. This severe negligence created an immediate, life-threatening risk of the wheel detaching entirely at highway speeds. 3.Yes, the initial loose lug nut failure was witnessed and confirmed on-site by the dealership's staff when I returned. Furthermore, the ongoing mechanical looseness and wobble were confirmed by my own driving experience immediately after their supposed "fix," and an independent shop inspection is scheduled to document the remaining issues. But I couldn't provide the key to the lug nuts because I couldn't find it in my car, after I brought the car to them. 4.It was superficially inspected by the O'Malley Honda service department, who merely rebalanced the tires and claimed nothing was wrong, they said they properly inspect for structural stud or suspension damage and everything seem good, and nothing wrong with it. 5.There were no warning lamps or dashboard messages. The physical symptoms—a heavy clunking noise, severe road wobble, and loose rear wheels—appeared immediately upon driving the vehicle off the dealership lot following their service on July 10th, and the rear end has continued to feel wobbly ever since.

VEHICLE SPEED CONTROL,ENGINE 2026-08-11 · NHTSA 11756223

This involves the paddle shift operation on the steering wheel. There are two paddles, one at 3 o'clock and 6 o'clock where the hands come into contact with the steering wheel. On four separate occasions, while driving at a relatively high rate of speed, my hands accidentally activated the gear mode by lightly touching one or both of the paddles. Very little pressure is needed to activate the gears. When this occurs, the vehicle shifts to a lower gear, and the vehicle rapidly decelerates from a high rate of speed to a low rate of speed while traveling. In addition to the unexpected and dangerous change in speed while in traffic, the shift into low gear causes the engine to rev and the noise from this caused me to panic while in traffic. On one occasion this occurred when I was trying to cross a road with oncoming traffic. The paddles are very close to where the hands come into contact with the steering wheel and very little pressure, only a tap, will activate the paddles and switch the vehicle into low gear. I have contacted Honda and there is no way to deactivate the paddles.

Auto Idle Stop failed as I was sitting at a red light. As I came to a stop at the light, the truck entered the Auto Idle Stop. When the light turned green and it was time to accelerate, I released my foot off of the brake and the engine stopped. It cut out right there. Warning lights came on and I had to restart the engine by totally shutting down the truck on a busy highway road. It took 2 attempts to get it to start. After this, I turned the Auto Idle Stop OFF using the button located on the lower console. I am taking it to the Honda dealership tomorrow to work on a remedy via the AutoIdleStopSettlement from Honda.

FORWARD COLLISION AVOIDANCE,LANE DEPARTURE 2026-07-23 · NHTSA 11752301

When driving the vehicle suddenly displayed warning and failure lights for the following: Adaptive Cruise Control, Lane Keep Assist, Road Departure, High Beam Support, and Collision Mitigation. The vehicle in the past regularly experiences issues with oncoming traffic (especially on 2 lane roads) when it comes to auto braking and forward crash warnings so I immediately brought the vehicle home as I was worried for my safety and the safety of others on the road that if these systems were now warning of malfunction the vehicle might auto brake in traffic for no reason and cause a crash. I took the vehicle in following this as I looked online and discovered there were multiple recalls on this vehicle for other various issues and I wanted the dealer to fix those in addition to determining if this was part of one of the recalls also. The dealership has diagnosed the issue as the forward multi-purpose camera and is stating it needs to be replaced to correct the safety issues of the vehicle. I reviewed online and found that just a coupe years ago this part was approx $800 and the dealer is not charging over $1600 for the part. The other issue is that I paid for the part and the dealer claims this part will not even ship until August 26 (over a month away). Additionally I have further researched this issue and found that it is a common failure on Honda and Acura vehicles and creates a major safety concern, yet Honda Motors has refused to address the issue and handle this as a recall as it should be done. New vehicles should not be regularly experiencing catastrophic safety system failures regularly and the manufacture not be held liable for the damages and not be able to fix the part or car in a timely manner. The fact the parts are in such short supply and backorder further attests to the common failure of this part. I would appreciate your immediate review and action of this matter to ensure that Honda is held accountable for the major safety failures they have created.

My 2021 Honda Ridgeline Sport experienced failure of the forward-facing Honda Sensing camera system. This camera controls safety features including Collision Mitigation Braking, Lane Keeping Assist, and Adaptive Cruise Control. The failure disables safety assistance features. Honda acknowledged the issue but refused to provide full repair coverage and only offered $941 toward a repair costing significantly more. I believe a safety-related camera failure should be investigated as a potential defect

STEERING 2026-04-22 · NHTSA 11733135

I CURRENTLY OWN A 2021 HONDA RIDGELINE SPORT AND IT WAS BROUGHT IN TO A HONDA DEALERSHIP THAT HAD DIAGNOSED A STEERING RACK FAILURE. THE QUOTED PRICE OF REPAIR WAS $4,000. AFTER DOING EXTENSIVE READING ON THIS ISSUE I LEARNED THAT SIMILAR ISSUES HAVE OCCURRED IN LATER YEAR MODELS AS WELL AS SIMILAR YEAR MODELS IN THE HONDA FAMILY. THERE WAS A RECALL OF 1.7 MILLION VEHICLES WITH THIS SPECIFIC ISSUE. THE VEHICLE MAKES LOUD AND CRACKING NOISES AND AT TIMES THE STEERING GETS HEAVY AND ALSO LOOSE WHILE DRIVING AT HIGH AND LOW SPEEDS. THE DEALER HAD RESPONDED THAT IT WAS A KNOWN ISSUE IN THE LATER YEAR RIDGELINE MODELS AND THERE HAD BEEN A SERVICE BULLETIN ON HOW TO RECTIFY THE ISSUE ON THESE MODELS. I DID NOT SEE ANY CURENT RECALLS FROM THIS YEAR, HOWEVER THIS DOESN'T MEAN THAT THIS IS NOT A KNOWN OR GROWING ISSUE FOR THE YEAR HONDA THAT I CURRENTLY OWN. PLEASE ADVISE. THANK YOU

The check engine light came on Dec 26 which I took to have checked and was told that it should go to the shop. The code was not being stored. I took it to the Honda dealership and they did a complete check and said the engine had gone back. The connecting rods and barrings cause the engine to fail and it needed to be replaced. I contacted Honda Goodwill and they declined to do anything to help repair the engine.

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

Vehicle started making a clunking noise that could be felt at 45,000 miles when steering left and right. An independent auto business found loose subframe bolts and lower control arm as well as checked sway bar links and found loose core support braces. The clunking stopped after the bolts were tightened. I found this very odd and concerning. 2021 Honda Rigdeline RTL. Cost to remedy included two hours of labor.

The contact's husband owns a 2021 Honda Ridgeline. The contact stated that while her husband was driving 55 MPH, the vehicle went into LIMP Mode and made an abnormal knocking sound. The check engine warning light was illuminated. The driver was able to pull over to the side of the road. The vehicle was towed to the dealer, where the timing belt, the water pump, and the tensioner pulley were replaced; however, the knocking sound persisted. The dealer determined that the lower bearing had failed, and the dealer recommended replacing the engine with a used engine. Additionally, the contact was advised that the oil pump was leaking and might need to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was filed. The manufacturer requested the vehicle service records. The contact related the failure to NHTSA Action Number: EA25004 (Engine and Engine Cooling). The failure mileage was approximately 102,000.

The Multipurpose Camera had an Internal Electronic Failure. Indications we all of the warning lights were illuminated on my dash. Initially it began when I had about 43, 400 miles on my truck. The warning lights would all remail lighted on starting the vehicle. I could restart the vehicle and eventually get the lights to go off. Then the slowly began to stay on permanently. I eventually made an appointment and took my truck into a Honda dealership and it was diagnosed a the failure of the Multipurpose Camera at 44,000 miles. The Honda Service Tech told me that none of my safety features were working at this time which really scared me. The Honda Dealership witnessed the dashboard warning lights and ran a diagnostic indicating the problem. The dealership ordered a replacement camera and replaced it. Parts and Labor were $2118.78. The first indication was when the warning lights began staying lit on my dash.

2021 Honda Ridgeline RTL-E. Part number 36160-T6Z-A62-M1 failure, hard code U3000-49. Results in total loss of Honda Sense Safety system. Including Collision Mitigation Braking System, Road Departure Mitigation System, Adaptive Cruise Control, Lane Keeping Assist System, Traffic Sign Recognition, Auto High-Beam Headlights. This appears to be a fairly common issue across Honda models where the multipurpose camera fails, generally due to heat from exposure to sun. The replacement cost and required re-calibration via the dealer is ~$2000. Living in northern California with extreme heat, I will assume this problem will resurface after a few years resulting in another $2000+ repair.

There were no warning lights illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted and confirmed that the VIN was not under recall. The failure mileage was approximately 43,928.

FORWARD COLLISION AVOIDANCE 2025-09-12 · NHTSA 11686830

The forward collision system frequently goes off from a vehicle simply driving in their lane normally. The truck alarms, shakes the wheel, and sometimes brakes automatically. This is alarming for my kids riding in the car and the braking is dangerous for cars behind me. This could cause a rear end collision.

Engine began knocking from the bottom end at 53k miles. It was determined that a connecting rod bearing had failed and Honda is replacing my engine under warranty. No cost was incurred to me but I am adding my complaint because my VIN is not included in the recall for this exact problem in other years close to mine and the recall my need to be expanded to a wider range of VINs.

FUEL/PROPULSION SYSTEM 2025-08-20 · NHTSA 11681946

While making a right turn from a yield sign into oncoming traffic and doing about 15 mph, I depressed the accelerator to speed up and the truck stalled for about 2 seconds. The RPM's drop and you literally lunge forward until power resumes. No warning lights come on and no codes are given. This put my safety at risk and the driver accelerating towards me at risk. This is the first time it happened with my 2021 Ridgeline. However, my 2019 Ridgeline had this happen about a dozen times. Honda Service could never replicate the issue with the 2019 Ridgeline, but there was enough data out there about defective High Pressure Fuel Pumps that they agreed to replace the pump. After replacing the pump, the issue went away. Now my 2021 Ridgeline is doing the exact same thing. I can therefore only assume it's the High Pressure Fuel Pump again. I see that Honda recalled 628,000 vehicles in 2021 and then recalled an additional 720,000 vehicles in 2024 for the High Pressure Fuel Pump failing. My current VIN for some reason is not in this recall. Honda Corporate was of no help whatsoever when contacting them. They told me my truck is not under recall. This is a severe Safety Issue and Honda needs to expand the recall to cover my VIN and any other VIN's that are affected by this defective High Pressure Fuel Pump.

My 2021 Honda Ridgeline engine failed in heavy traffic on the freeway. The car malfunctioned and I lost complete power and started coasting and barely made it through 4 lanes of heavy traffic before the car coasted to a stop. Very dangerous and very lucky not to get hit changing lanes and then waiting on the freeway for assistance. I've made regular oil changes as directed by the computer on the vehicle. The problem was not connected to a lack of oil. I'm [XXX] and I take very good care of my vehicles. Not one scratch on my black edition Ridgeline. My vehicle is still at the Honda dealership. I don't believe I should pay for another engine nor do I have the money to do so. Having a complete engine failure on the freeway is a major safety issue and Honda needs to fix it now and in the future.

This has something to do with circuit board for the seat sensor that activates air bag? I can’t get dealer to take care of recall. They keep saying we don’t have the parts. This is going on since at least September of last year. Why have recall if they aren’t going to do anything about it? They make appointments and then cancel. I have called Honda Customer Service number(twice) listed on the recall paper twice. Always get told to call dealer and talk to them. Dealer makes appointment and then cancels a few days before the date to bring it in. I have contacted dealer many times about this. Why issue a recall and then don’t fix anything?

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.

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.

LANE DEPARTURE,FORWARD COLLISION AVOIDANCE 2025-01-18 · NHTSA 11636846

At 48,000 miles, the vehicle began to experience multiple Advanced Driver Assistance Systems problems, including Adaptive Cruise Control, Forward Collision Warning, Automatic Emergency Braking, Forward Collision Warning, Lane Departure Warning, and Lane Keeping Assistance, which rendered all these systems inoperable. Systems that were designed to mitigate collisions became non-functional, and continuous warnings on the dashboard were a distraction while driving. Dealer scanned the vehicle with a code U300-40 Multipurpose Camera Unit/Millimeter Wave Radar Internal Electronic Failure, and diagnosed a failure of the multipurpose camera, which was then replaced and recalibrated. I have retained the failed unit after paying to have the replacement installed and calibrated. All warning lamps for the above mentioned systems flashed on my dashboard every time the vehicle was started, prior to the dealer repair. The safety of the driver and those around them was affected because repairs for this safety feature suite may be cost prohibitive to some ($2000) and they just won't fix it.

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)

What happened? While driving in the right lane on a two lane highway, I slowed slightly when approaching a vehicle ahead of me. I then started to move into the left lane to pass when the engine stopped (as confirmed by the tachometer quickly dropping to 0 (zero) rpms). In response, I started feathering the throttle and moved back into the right lane where the engine restarted on its own. I then continued my trip without further incident. This happened with approximately 60,000 miles on the truck which was purchased new by me. I did have a similar incident when the truck was much newer but didn't pay much attention as I was still learning Honda's ADAS and wasn't sure if 'pilot error' came into play. And to clarify, the only safety that was in use this time was Lane Keeping Assist but it wasn't active as I was actively signaling my lane change. Questions under your General Guidelines: While the engine stopped unexpectedly, I don't believe it was an engine fault simply due to the number of miles I've driven the truck with no similar problem. While my wife and I weren't at risk since traffic was light at the time with no one behind us, I can see a safety issue in heavier traffic, especially if the engine doesn't restart as soon as it did. The truck has not been inspected by Honda. I did file a complaint with American Honda (case #14787271) and they simply suggested a visit to my local Honda service department. But due to the very limited occurrence of this issue, I can't see how their service department can be of any help. During the incident occurrence, there were no warning lights, messages or otherwise hints of an impending problem.
