While my husband was taking our daughter to school on 01/05/2026 around 6:00am, a warning message flashed on the radio screen: "EMISSIONS SYSTEM PROBLEM: The engine is not operating properly. Avoid high speeds and visit your dealer as soon as possible. If the indicator is blinking, stop in a safe place where there are no flammable objects. Turn off the engine for 10 minutes or more to let it cool. Restart the engine. If the indicator continues to blink, immediately have your vehicle checked by the dealer. " This was a safety at risk for my husband, my child, and the public - anyone driving near the vehicle. My husband pulled over and called me to let me know what was happening. He called AAA to have the car towed to the dealer. And called the dealer to let them know we were having the vehicle towed to them. They diagnosed it with "a unit in need of engine replacement." The car was purchased as a certified pre-owned vehicle in 12/2021. It is a 2021 Honda Pilot and had a few hundred miles over 8000 at the time of purchase. The dealer is not taking responsibility as the miles 62,007 are just over the 60,000 mile powertrain warranty. And over the 5 years by weeks - 11/2020 to 01/05/2026. I was advised to contact American Honda. They basically told me I was not eligible for a goodwill assist as because: 1.) I was not the original owner 2.)I did not have my service done at Honda. However, I did have documents of all of the service that had been done and sent those receipts to the Honda dealer. The engine failed. The dealer confirmed engine failure. The vehicle did stall out - at a stop light and took several minutes to start back up around October or November 2025. There were also some engine noises, including loud noises while accelerating, especially in Sport mode.

I have had two major problems with this car. At approximately 84,000 miles, the engine started making a very loud noise, regardless of speed. It was first diagnosed by an independent service center as a control arm bearing failure. I contacted Honda Corporate and was told that it had to be diagnosed by a Honda dealer/service center. It was then diagnosed as a failure of the control arm bearing by a Honda dealer/service center. I was told the engine had to be replaced. Honda Corporate offered a 50-50 split, leaving me with a bill of $8480. This is completely unfair and unjust for me to have to pay this for a manufacturer's defect. In the second incident shortly thereafter, I was on the highway in traffic when the automatic stop-start function failed, and the car stopped and did not re-start. I had cars backed up behind me, and it was a very unsafe situation. After turning the car off completely, I managed to restart it, and got off the highway. The problem continued afterwards, and I had to turn off the function manually in order to drive the car at all.

When driving and wanting to accelerate at 65mph car just because limp, won-??t go when accelerating for a few seconds, speed drops, then you press back on the accelerator and after a few times the car goes back to normal. So, you loose control of the accelerator for a few seconds and you cant go faster, it just freezes and speed drops. This has been happen g for awhile. I even called Honda Corporate to advise them. It-??s been happening for over 2 years. It comes and goes. We are starting to hear a clunk noise now.

- Mesa, AZ, USA

Transmission failed and car would no longer get into gears. It started when I tried accelerating on the highway and heard a whine The car would not accelerate. I tried again and this time it accelerated just fine. Made it home and the next day the car would turn on but not go into gears. The front panel showed warning of -??Transmission Failed-??, and -??Engine trouble-??. The dealership diagnosed that I needed a new transmission for $9,000! The previous day the car was working fine until and after that -??whine-?? noise. I have not paid for repairs yet.

My Honda Pilot experiences a serious safety issue with the Auto Idle Stop feature. When the system engages at a stop (such as a red light), the vehicle sometimes fails to restart, leaving me stalled in traffic. This creates a dangerous situation for myself and other drivers. The problem appears to be related to the Auto Idle Stop system and/or the auxiliary battery. Many other Honda owners are reporting similar issues, which suggests this may be a widespread defect that needs investigation. I just dropped the car at Honda dealership for further inspection

While driving on the highway, I heard a loud whirring noise then my vehicle started to decelerate. After continuing to push on the accelerator, an error message appeared that stated something to the effect of "move vehicle from neutral to park". I tried to put the vehicle back into drive but my car had thrown itself into neutral and would not go back into drive. Another error message came up and indicated something about the transmission and that I should pull over to safety and put the car in park (or something of that nature). I was able to pull over but the car was frozen and I could not put the car back into drive, only into park. The vehicle was towed to a dealership where I was told the car needed to have the transmission replaced and that the Carfax report showed the transmission fluid had never been changed/replaced. The car is only four years old and I have never received an error or warning on the vehicle that there was an issue with the transmission fluid.

The contact owns a 2021 Honda Pilot. The contact stated that while stopped at a traffic signal, the vehicle independently shifted into neutral(N). The contact shifted vehicle into park(P) and turned off and restarted the vehicle and shifted into drive(D). There were no warning lights illuminated. The contact had the vehicle towed to a dealer. The dealer diagnosed the vehicle with a faulty brake switch and determined that the 12-Volt battery needed to be replaced. The vehicle was repaired; however, the failure recurred, and the vehicle independently shifted into neutral(N). The contact stated that the failure had occurred while stopped with the vehicle still in drive(D). The vehicle was taken to the same dealer however, the dealer was unable to duplicate the failure or determine the cause of the failure. The vehicle was not repaired. The manufacturer was informed of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 38,000.

The heat stopped working last year when parked. To the point where it's blowing out cold air. I brought it to the dealership and they told me nothing is wrong. It appears to be the thermostat which I now have to replace on my own. Also the transmission slips randomly and I was told that could not be repeated either. Yet the car only has 90,000 miles, this should not be occurring.

- Oxford, CT, USA

When shifting from reverse into drive, there is a 5-10 second hesitation. I push the gas and the car does not go. It will eventually accelerate at a very high speed. Does not happen every time, but often enough to be very dangerous.

- Waltham, MA, USA

When driving the car and stopped, the car goes into idle engine automatically. There are have been 5 incidents where the engine wouldn-??t turn back on. The car starts beeping and flashing to put in park, shut off and restart. This is extremely dangerous when in the middle of traffic, cars honking and my children in the car getting nervous. Luckily I have not had an accident yet and figured out how to not use the -??idle stop-?? feature to prevent this from happening but it-??s not a long term solution as I have to stop idle feature every time the car is turned on.

Hello, Twice in the past two months, my car's engine has lost power while driving on the highway. First, while entering and merging onto the highway, and once while exiting the highway. Both times, the check engine light came on, pressing the gas pedal had no effect, and we could only coast to the side of the road. Both times we had to restart the vehicle. After the first incident, I went to the dealership. They "fixed" the vehicle, replacing gaskets that Honda knew might fail but didn't issue a recall (only fix if there is an issue). This obviously did not fix the issue. Thankfully we did not have an accident, but complete loss of power could have been disastrous. I now have to go back to the dealership.

Honda Pilot 2021 Elite AWD w/ 34k miles shuts down at a complete stop e.g. traffic light, stop sign or highway stop and go rush hour. Panel says put in Neutral, but the push button transmission shift does not respond. Attempts to restart with the push start/stop button and fails multiple times first and then it starts again, while other motorists are honking behind you for blocking traffic. Major safety concern.

The Auto Idle Stop is defective on this vehicle and has resulted in multiple incidents where the vehicle stalls after the break is applied in sitting traffic. I have had near collision experiences that pose a severe safety risk. The car jolts forward after releasing the break at an intersection, and immediately becomes immobile. This has happened in sitting traffic, at intersection and more dangerously, while trying to make a left turn which has left me stranded in the middle of busy intersections at risk of nearly being hit by moving traffic. Honda has done the software update on the vehicle and yet, this continues to happen. Honda needs to be held liable as this will result in injury and/or death to consumers.

I will be filing a issue with our 21 Honda Ridgeline too as the same problem has occurred in both vehicles with the same engine and transmission. This has happened a total of 3 different times. When I drive the Pilot for a long time (over 4 hours)on the expressway and then pull off on a ramp and turn left the vehicle will go into safe mode. The engine light will start flashing and you can not drive over 30 mph. The engine runs rough and idles hard. I have contacted Honda and the dealership I purchased it from. Honda has acknowledged this is a problem and has occurred multiples with many different vehicles. The dealership I work with has acknowledged the same thing as they have several vehicles that have been brought in with this problem. I have waited several months for Honda to come up with a solution, so far they have not. This is a safety concern because what would happen if this same situation came up when I'm pulling my trailer or on the expressway at higher speeds. This could cause an accident. This first started on my Pilot in December of 2021. It has happened several times since then. Every time there is no code the computer keeps, even though each time the engine light is flashing. What I have been told is the computer thinks the engine has backfired and goes into safe mode, but Honda doesn't know why it does this. If you turn the vehicle off and restart it, the problem goes away. When the dealership has run a diagnosis off the computer, there are no codes the computer throws. Even though the check engine light is flashing when this occurs.

This vehicle has a pushbutton transmission "gear selector". It is IMPOSSIBLE per the owner's manual, and further confirmed by the dealership, to PLACE THIS VEHICLE IN NEUTRAL without the engine running. This is an unacceptable safety hazard. If the vehicle stops running in busy traffic or in an intersection, or otherwise in a zone such that imminent danger of collision is necessarily introduced, it is impossible to push the vehicle out of danger, off to the side of the road. Further it cannot be towed without necessary imparting damage to the drive train. Honda requires the owner to BUY A SPECIAL TOOL, Lock Release 07AAA-TZ3A100 which requires removal of underhood components to place the transmission in neutral, and it (apparently) cannot be maintained there without an extra person available to hold the tool against spring return pressure. This whole affair is simply UNBELIEVABLE. As I write this, there is NO INCIDENT, as the vehicle is relatively new to us. But I'm 61 years old, and have had to place inoperative cars in neutral to get them out of harms way, at least a dozen times in my life. Note that this shortcoming manifests itself as simply as whenever the vehicle runs out of gas. This cannot be allowed to happen. Are there no adults left in the building designing these cars?

I just bought my brand new 2021 Honda Pilot I had it for 1 week so I decided to take it to las vegas on the way there it was fine but on the way home I'm coming down I started to feel a jerk in the transmission I didn't think nothing of it so I kept driving. But for a new car it should not be doing anything like that at all so I took it to Honda dealer and they did a multi inspection check and said they didn't find anything wrong with it and everything shift fine but when I took it home a week later it's happening more and more especially when it's traffic you will feel it way more I just hope it don't go out after my 60K miles warranty right now it's only 2,500 miles and I feel I got a lemon I already have transmission problems but it just too new to go out right now
