NHTSA Complaint #11536945 — 2017 HONDA ODYSSEY

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.
