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. …
Odometer Fraud. The contact purchased a 2012 Honda Pilot. After contacting the seller on Facebook Market Place the contact purchased the vehicle and later discovered that there was a mileage discrepancy. The vehicle was a private sale. At the time of purchase, the odometer mileage reading was 94,397. After obtaining a Vehicle Carfax, the mileage listed for the vehicle was 204,943.
The car started smoking, I was able to pullover and get out. The fire department came and removed the hood because it was too hot and appeares to be on fire. They disabled the battery. Car was towed to mechanic and inspected for cause. It was discovered that the alternator melted and the wire harness was burnt and plastic components melted. Car has been totalled.

Odometer Fraud. The contact purchased a 2012 Honda Pilot. The contact then discovered a mileage discrepancy. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 67,450.

While driving the vehicle at around 45 MPH it suffered a complete loss of power for 3-5 seconds. The dashboard lights illuminated and then the vehicle restarted without having to restart via the ignition and all of the dash lights turned off. This has happened intermittently on two prior occasions. No electrical issues were evident, new battery and charging system appears to be functioning normally. The contact stated that the dealer found that the issue was a faulty positive battery terminal connector. It was replaced.
Check engine light came on followed by shaking of the vehicle. The code was checked indicating a cylinder 1 misfire. This has been an ongoing issue of cylinders misfiring. The spark plugs and coils have been replaced multiple times and the issue is still persisting.
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.
My wife pulled the vehicle into our driveway and exited the car just a she noticed white smoke coming out from under the hood. She called me out of the house to look and I saw there was a fire in the engine compartment. I tried to put it out with a fire extinguisher but it spread too fast. The end result is the entire vehicle was burnt with not much left. I am assuming it was something electrical due to the nature of the initial smoke and the location of the fire origins.
When backing up using the backup camera the camera display will sometimes go black on the screen. I have almost on two occasions almost hit someone backing out of a parking lot. This is a intermittent problem that comes and goes. I feel it's a safety issues to have your vision suddenly cut out with no warning.
