Per Honda dealership technician: oil seeping into cylinders 1-3 when VCM system is on. Spark plugs are fouled up and causing misfires on engine. Scoring on cylinder 2 also likely due to VCM issues requires engine block replacement. The above engine issues are the reason for blinking check engine light, traction control disabled light, and forward collision warning disabled light to all be on. These ultimately are occasionally causing stuttering/shuddering of the engine during acceleration. While trying to accelerate on an freeway on-ramp the engine appeared to hit a rev limiter at ~4,000 RPMs and wouldn't up-shift to the next gear while doing ~45 MPH with other vehicles behind us also trying to accelerate. Had to let off the gas and gently accelerate over a longer distance/time keeping RPMs low and was able to accelerate to 75 MPH speed limit after merging onto freeway. Vehicle is otherwise in good condition and has maintenance attended to regularly.

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. 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.

UNKNOWN I was urged by a Honda World representative to give my account. My vehicle has intermittently flashed forward collision warning failure/lane departure warning and the check engine light. The issue has been reported to the dealership and they've acknowledged that it seems to be a well-known issue with this particular make/model/year vehicle, due to a faulty part. In order to issue a recall there need to be reports. So here you go.
