Auto start-stop failure on other Odyssey years

No other Odyssey model year has enough reports of auto start-stop failure for a sheet of its own. See every Odyssey year.

What this problem usually is

Start-stop complaints describe one moment: the engine shuts off at a light, as designed, and then doesn't come back when the driver lifts off the brake. Owners report sitting in traffic with a dead engine, having to shift to park and restart by hand, and dealers who find nothing wrong on the first visit. It usually happens more than once before anyone files.

Android Auto doesn't work either which is a known issue as well and it is a basic safety feature to keep driver's attention on the road and not on their phones.”

Should you keep driving it?

This page can't tell you that. 0 of 53 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.
