2017 Honda Odyssey: check engine light

Filed Sep 1, 2024 · Driver assistance, Transmission · NC

Driving one day without warning the van was shifting from 2nd to 3rd gear when there was a hard slam, then the check engine light came on as well as the forward collision sensor failure. The van went into limp mode on the highway which was very dangerous. After having the Honda dealership investigate two times they said the only thing they could do is completely replace the transmission.

Flashing check engine light came on. Took this to the dealership and they found that one of the cylinders misfired and a sparkplug has fouled oil. Piston rings needed to be replaced. This happened because of oil buildup when 3 of the cylinders stop firing when the engine is in "fuel efficient" mode. As I understand it, the vehicle design is to turn off half the cylinders when I drive efficiently and that causes buildup over time. This is a ticking timebomb that will eventually cause this damage and render the vehicle undrivable.

Engine failure, requiring all new ignition coils and spark plugs (62,000 miles). Car ran well for 3 weeks, and resumed having acceleration issues, engine/transmission judder and check engine light returned. Brought back to mechanic and replaced a failed ignition coil. Was directed by the mechanic to bring to a dealer if the issue continues as it's likely due to a cylinder issue which is causing ignition coils to fail. Brought to dealer with engine and transmission issues. Diagnosed as bad transmission fluid requiring flush and fill 3 times: $850. Told that there are no engine issues as a result of diagnostic. Drove car home (4 miles), and engine issue became worse with flashing check engine light returning light, jerky drive and no acceleration. Brought back to mechanic and diagnosed with piston ring failure requiring extensive engine work, including but not limited to piston ring replacement, cylinder/piston rehab. I have contacted Honda corporate requesting action as it's just outside of powertrain warranty. Claim has been pending for 2+ weeks. Vehicle is parked at dealer pending resultion. Unsafe to drive for mechanical reasons, and car is subject to stall. Only able to drive slow speeds, for short duration.

Twice within 3 months our 2017 Honda Odyssey (65,000) miles has had a misfire in the engine and had a flashing engine light. Had to change spark plugs and coils twice and they had to adjust the pistons. Mechanic says he sees this a lot with this year and make. He also said it’s something you would say after 100000 miles maybe. Not with such a new car.

Brand new car 2017 honda odyssey with less than 300 miles driving on a winding road uphill and the check engine light starts flashing. Manual advises to pull over to turn off and let the car cool down. Did that and then the vehicle stability assist light also goes on. Car starts to shake when you accelerate. Honda dealership said it was a misfire and covered under factory warranty. How can a new car already have engine problems??
