On April 9, 2026, my daughter came in from school and parked her Honda Pilot at about 5:10PM. At about 7:03PM, my wife and I were sitting outside and heard a loud POP, it sounded like a car backfiring. I went to investigate and saw a little smoke and a small orange glowing piece of something on the ground under the vehicle towards the front of the vehicle. I grab a fire extinguisher from my work truck and went towards the vehicle. The car was locked and I saw flames under the hood standing by the driver door looking down where the windshield wipers are. I used the extinguisher till it was empty and the flames kept getting worse. I just walked away and my wife was already calling 911. No one was hurt no damage to any exposures. My daughter did not indicate that anything was wrong with the vehicle. No lights on, no smells, everything ran fine. It had 154,000 miles on it. …
The contact owns a 2012 Honda Pilot. The contact stated while at a stop light, the engine shuddered and the vehicle was unable to accelerate. The check engine, battery, traction control, and Variable Torque Management 4-WD system (VTM-4) warning lights were illuminated. The vehicle was taken to the local dealer and diagnosed with piston and piston ring failure mentioned in Honda bulletin 13-082. The vehicle was repaired; however, the failure reoccurred. The manufacturer was notified of the failure. The approximate failure mileage was 85,000.
The check transmission light comes and goes. Ive had the transmission flushed with no issues. It pulls codes for the torque converter as its supposedly getting stuck per mechanic or is over heating and throwing the code. It does not drive rough and I believe it is a faulty code that needs to be addressed and updated and cleared. Ive had it cleared out once and it stayed off for a whole month. The light and blinking D doesn't come on all the time or in patterns so that also tells me it isn't a transmission issue or it would be on more frequently and consistently. To where when mine comes on and then I shut my car off for an hour it stays off for quite some time. This really needs to be addressed instead of causing car owners unnecessary costs for diagnostic purposes through a Honda dealer which costs 100.00 or more or even them putting in a complete new transmission.
Excessive oil consumption which led to engine misfire while driving and trying to merge onto the freeway. This cause a significant loss of power and poor performance by the vehicle. Fortunately the roadway was not busy, but this issue could have caused an accident. Took the vehicle to local mechanic, Affordable Automotive (Chico, CA). They ran a diagnostic and it revealed a P0301 and P0175 code. They removed the spark plugs which showed excessive fouling and they replaced them. The specific cylinder effected was Cylinder 1. I have contacted Honda and filed a claim (Case #12234271). They opened a case and initially had good communication, but have since stopped responding and have not provided me with a conclusion. Honda initially responded on May 21, 2021.
Unusual amount of oil consumption. Faulty cylinder 3. Gaskets cause the oil to leak into the spark plugs causing the engine light to come on with loss of power. Changed cylinder 3 spark plug at least 10 times or more since purchasing the vehicle in 2021. Oil also drips onto the alternator, replaced it twice in 9 months. Wheels and steering wheel shake when hitting the brakes. Replaced brakes and rotors twice as well.
As I proceed to accelerate onto a highway or road my vehicle is very hesitant no matter how far you push down on the gas pedal it will not go and then all of the sudden it lurches accelerating the speed very fast as if it's trying to catch up. This has caused me to almost I have three accidents now. I have to be very cautious when entering an intersection or pulling onto a freeway as my vehicle declines to accelerate as it needs to causing people to run into me almost. It is a pretty significant delay for the vehicle to catch up on its own and could be very dangerous for anyone. I have read several columns where customers with Honda pilots have experienced this same ordeal and yet it's hard to take to a dealership and explain what's going on and then get in the car and it not happen right away but my car does it almost every single time you try to accelerate on to any road. …
Purchased the vehicle used from a franchise dealer and am the second owner. The engine hesitates at low speeds (approx. 10 MPH) when accelerating. This becomes apparent when attempting accelerate from a stop light, accelerating from a turn, merging onto a freeway, changing lanes, etc. It does happen periodically and I am unable to reproduce the issue on-demand, but it seems to happen daily whenever the car feels like it. I am surprised there is no recall issued for this, as I have already had a couple of near missing when trying to merge onto the freeway with steady flowing traffic and when crossing an intersection from one side of the street to the other. I have yet to take the vehicle to the dealer, as it is out of warranty and there does not appear to be a solution to this issue, so I want to understand what my options are. I'll be reaching out to American Honda soon.
The gasket on the spool valve on older Honda pilots is known to fail. The failure results in oil leaking onto the alternator which fill cause the alternator to eventually fail resulting in a loss of power to the vehicle. This recently to my wife while driving on a busy highway. Oil leaking from the spool valve fouled the alternator resulting in the loss of power to the vehicle including to the power brakes and power steering. This engineering failure causes a hazardous situation. The vehicle had been recently serviced by Honda for an oil change and the issue was not noticed. At minimal, Honda should recommend replacement of the gasket as part of routine service after a period of time or certain mileage. A simple google search identified this issue with older model Honda pilots.
Vehicle developed a vibration around 45000 miles in rear and thought tires needed rebalancing. That didn't help and after vibrating on a 1600 mile trip had dealer replace tires with original brand and size after discussing problem with them. $1000 later I took the car back to dealer and complained about vibration. They rebalanced tires on hi tech balancer. 275 miles on new tires and still vibration is there. Went back today because of vibration and they did software update and replaced right rear tire. Service manager and then general both rode with me I vehicle and they agreed the vibration is still apparent. They think it's inherent with the Honda Pilot. It obviously is not something that is normal. Who what's to drive a car vibrating all the time.
Tl* the contact owns a 2012 Honda Pilot. The contact stated while driving 60 MPH on the highway, the vehicle jerked while shifting gears. Additionally, there was an abnormal vibration in the steering wheel. There were no warning lights illuminated. The vehicle was taken to an independent mechanic where the spark plugs were replaced however, the failure recurred. The contact stated that the vehicle was not taken to a dealer due to the distance of the nearest dealer. The vehicle was not repaired. The manufacturer was notified of the failure and suggested that the vehicle be taken to an authorized dealer for assistance. The failure mileage was approximately 137,000.
