2016 Honda Odyssey

This is a problem with the car’s variable cylinder management. It causes the spark plug to degrade, the engine cylinders fill with oil and damages the piston rings. This has happened to me on my 2016 Honda Odyssey which has less then 50,000 miles. When the engine cylinders misfire while driving, it causes sudden loss of power and an inability to drive. The repairs are very costly. There was a class action lawsuit aimed at this very problem in the 2008-2013 Honda Odyssey - Honda settled the lawsuit March of 2014. Honda extended the warranty and would fix the issue on the existing 2008-2013 Honda Odysseys. Honda has not fixed the problem and they continue to sell vehicles with this known issue and not disclosing it to their customers. It remains a safety issue while driving.

Control Module system failure escalated to an extent where the vehicle will not turn off after pushing the off button and cause flickering while the vehicle is in motion. Part #38329-TK8-A01 is currently in the shop due to part replacement on critical backorder. The vehicle has and can shut off during transit making it a hazard on the road. The vehicle had to be disconnected from the battery to be able to shut off the vehicle, but the on-road transit shut-off was not reproduced. Honda Dealership has inspected the part, and they're unable to correct or resolve the part without a complete replacement. Issues before the incident: Lights would flicker, a clicking noise would be heard from under the hood, car alarm would go off with nothing attempting or touching the vehicle.

This is a problem with the car’s variable cylinder management. It causes the spark plug to degrade, the engine cylinders fill with oil and damages the piston rings. This has happened to me twice now, where the engine cylinders misfire while driving, causing sudden loss of control of the vehicle and an inability to drive. The repairs are very costly. There was a class action lawsuit aimed at this very problem in 2013, but Honda has not fixed the problem and it remains a safety issue while driving.

I was driving down a city road and engine light came on as well as traction control light. The car began shaking and lost power slowing down while I had 4 kids in the van. I took it to a Honda dealer the next morning and they said that oil is leaking past the piston rings and fouling the #3 spark plug causing misfiring. They suggested a replacement of the engine as they indicated a head job may not fix the issue. The engine light had come on once before accompanied by the loss of power and shaking about 4-5 months prior but the issue was not found at that time by the Honda service shop as when I brought it in the check engine light was gone. But I I had all the spark plugs replaced as I was at approximately 106,000 miles at that time. Now I'm at 109,000 and the issue returned as noted above, but much worse. Basically I'm forced to sell the van as it's unsafe to drive and too costly to repair.

While driving my family on a major highway, the flashing check engine light was triggered Upon checking the oil level, which was fine, I again slowly drove the van to a mechanic. The mechanic removed all spark plugs and checked the coils. Spark plugs 1-3 all had oil on them causing them to foul and the coil on piston 3 was destroyed. This very same issue was the cause of a class action lawsuit for which honda issued recalls and extended warranties for vehicles ranging from 2008 - 2013, yes the issue continued in honda vehicles such as mine until 2018. I am now forced to pay for a repair that should have been covered under a voluntary recall. Oil in the spark plugs is a known fire hazard and this willful neglect by honda placed the lives of myself and my family at risk. Even more shameful is that multiple honda service departments in my area were contacted as a result of this faulty piston issue and each independently stated that this is a known issue in honda models up through 2017. If honda service centers can attest to this, and they are the face of honda america to consumers, yet have taken no responsible actions to date to offer consideration for their loyal patrons, then the government has a duty to protect consumers through a mandatory recall to address this prevalent safety issue. Do so now before an engine fire caused by gross negligence takes the life or lives of innocent children.

At highway speeds (50-65mph), the transmission would jutter/shudder when trying to either accelerate or decelerate from constant speed. The issue incrementally got worse and got to the point where the van was undrivable on the highway. I found the service bulletin 14-043 and brought the van into my Honda Dealer with a copy of the service bulletin. They test drove my vehicle and agreed this was the issue. The software was updated and ATF was flushed at no cost.

At highway speed (70mph), our van suddenly lost acceleration while the engine began to shudder while the check engine light came on. I had to maneuver to the shoulder of the highway and turn off the vehicle. Upon trying to restart the vehicle, both the check engine and Forward Collision Warning failure messages appeared. The vehicle required towing by AAA to a repair garage. The garage reported that the malfunction code was "Misfire Cylinder #3". Cylinder #3 and spark plug were removed and cleaned due to deposits from oil entering the engine.

On December 7, 2022, while driving my family of six, my 2016 Honda Odyssey EX-L with 83,000 miles triggered a flashing check engine light and lost most acceleration while on a busy highway. I was able to limp the vehicle to a repair shop who identified that the van appeared to be burning oil. Oil was changed in its entirety and was advised to check oil frequently. On February 5, 2023, again while driving my family on a major highway, the flashing check engine light was triggered along with the antilock braking system, lane departure warning and front collision warning, along with a display message of front ‘FCW system failed’. Upon checking the oil level, which was fine, I again slowly drove the van to a mechanic. The mechanic removed all spark plugs and checked the coils. Spark plugs 1-3 all had oil on them causing them to foul and the coil on piston 3 was destroyed. This very same issue was the cause of a class action lawsuit for which Honda issued recalls and extended warranties for vehicles ranging from 2008 - 2013, yes the issue continued in Honda vehicles such as mine until 2018. I am now forced to pay ~$4500 for a repair that should have been covered under a voluntary recall. Oil in the spark plugs is a known fire hazard and this willful neglect by Honda placed the lives of myself and my family of six at risk.
