Engine Oil Leaking problems of the 2014 Honda Odyssey

I was driving 70mph on an interstate. The battery light came on. There was no immediate change in vehicle performance and there were no odors present so I continued driving for several minutes towards the next exit. About . 5mi away from the exit, the abs, fcw, ldw, and brake lights came on, the air conditioner and console turned off, and the automatic transmission disengaged. This prevented the vehicle from being able to accelerate. The entire vehicle essentially lost power. The local dealer diagnosed the issue as an oil leak in the spool valve that then destroyed the alternator and fried the battery. The manufacturer (Honda) recenty issued TSB 20-023 detailing the problem and repair procedure, but it was limited to the source of the leak, not any of the other components that were damaged. My understanding of the incident leads me to believe a fire could have broken out due to the location of the leak onto the other engine components.

Tl the contact owns a 2014 Honda Odyssey. The contact stated that the vehicle decelerated while driving and the engine warning indicator illuminated, which meant that the fcw and ldw systems failed. The vehicle was taken to an independent mechanic and who diagnosed that the spark plug needed to be replaced and the cylinder was leaking oil, which caused the spark plug failure. The vehicle was repaired, but the failure recurred on three different occasions. The vehicle was not taken to a dealer. The contact stated that the mechanic called the dealer and was informed that the 2013 models were experiencing the same failure. The manufacturer was made aware of the failures and informed the contact that there was no recall and that the vehicle was out of warranty. No further assistance was provided. The failure mileage was approximately 216,000.

2014 Honda Odyssey which is experience the same issue as the 2013 Honda Odyssey where piston ring 1 -4 with leak oil and foul the spark plugs. When this occurs the engine misfires and vibrates significantly and reduces drivability. Due to the warranty extension on prior years this appears to be a known design defect for this model and engine but not for this model year. When the issue has manifested it has been when driving both times has been on a city street. Estimates for repair are $4,200.

I was in traffic and driving a steady 50 mph when the engine suddenly shutdown. After I realized what the situation was I placed the transmission into neutral, steered the car off the road as soon as it was safe to do and stopped. I just had the engine oil and filter replaced when this event happened 3. 7 miles from the repair shop. I suspected a problem with the oil change. After stopping I checked for oil under engine (none) and then checked the dipstick (full). I had the van towed to the shop where their personnel checked under the engine for an oil leak and then checked the dipstick as I had done. They told me to take the van to Honda. It’s been a week and Honda said I need new heads for the engine because the timing “jumped”. The oil change had no effect on this failure. So far, nobody at Honda can tell me what actually caused the timing to “jump“. The total repair is being done by Honda and is covered by the Honda’s new car warranty. I’ve never had any kind of problems with this van prior to this unexpected and sudden failure.
