What owners wrote

“Engine has a rod knock problem at 72,000, miles. Vehicle will likely need a full engine replacement.”

“Engine has been “hiccuping” for a few months and making a knocking sound. Brought it to Honda on 3 separate occasions and they “could not replicate” the sound. And said it’s normal. I’ve had 2 non Honda mechanics look at it and they agree it sounds like a rod knock and engine failure is going to happen sooner rather than later.”

Filed Nov 15, 2024

“Knocking noise began so I took it to a Honda dealership. They said I have a “lower knock noise” and need a new engine because a bearing went out for a rod which could cause my engine to seize. Though there is a recall for some 2018 odysseys, I’m being told mine isn’t covered. Apparently there are many more people with the same vehicle and the same issue as me. I’d like to see this included in the recall”

“Manufacturing Engine damage/failure. Synthetic oil was used at all oil changes every 5K miles. However, after only 3K miles after last oil change the oil level was low and dirty. Engine light started flashing and failed to accelerate. Engine also started making a knocking noise.”

Should you keep driving it?

This page can't tell you that. 0 of 32 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
