Oof. Unless he’s trying to make a pro union statement, I think he got the wrong van. I would never buy a Stellantis product. He should have gone with a Sienna or Odyssey
Honda eco mode shuts off one bank of cylinders in cruising and coasting conditions. In a very short period of time (60K miles for ours, I’ve seen reports of it happening earlier), those cylinders running without combustion will eat the piston rings. If you drive less aggressively, this happens sooner. Honda may or may not pay for the several thousand dollar repair, depending on which corporate warranty adjuster you happen to get.
There was already a class action for certain model years, with a TSB. But they didn’t actually change anything about the design, so it does happen in any 3.5V6: Odyssey, Pilot, whatever.
The older ones had problems with carbon buildup causing oil consumption because of the cylinder deactivation that’s why many of the forums are filled with people disabling the vcm module

Up until a couple years ago, the Pacifica was the only hybrid available. The Sienna has a hybrid now. But that’s it.
I’d never buy any Honda with the 3.5V6 with eco mode. At least not without also buying an aftermarket harness to disable eco mode.
It’s a minivan, dude. You’re already not buying it for the performance.

That is horrifying. Do they still use the engine?
Yup.
They made changes to the gen 5 (2018-2023) that fixed that particular issue.

The newer ones, too.
