I don’t think there is anything inherently wrong with the VCM engine. My cousin had a 2008 Accord V6 VCM purchased new and the engine never gave him any issue. It didn’t use any oil when he traded it in with 200,000 miles. I will say he was adamant about keeping up with the maintenance intervals.
Back when I had my 2013 Accord, I went to the dealership for its first complimentary oil change and there was a younger woman with 3 or 4 little kids, one was a baby and she was carrying him, the others were climbing in and out of the van. Anyway, she was talking to their service advisor in the service drive, while her 2005-2010 era Honda Odyssey was knocking and tapping like mad. I don’t even know if hers had the VCM engine.
Regardless, I have no idea who the woman was, but I’ve known so many people throughout the years that resembled her. Main priorities are the kids and the family, vehicle maintenance is the last thing to worry about. There’s nothing wrong with that. It’s my belief that these engines were a little too advanced for minivan and family SUV use. Any VCM/cylinder deactivation engine needs to be running synthetic oil IMO. With these minivans and suvs, they more than likely got the cheapest oil change possible and likely over extended the interval.
