“I own a Honda Odyssey equipped with the Auto Idle Stop (automatic engine start-stop) system. The feature has not operated properly and behaves inconsistently. In addition to frequently failing to engage when the vehicle is stopped, I have experienced several instances where the engine shut off as part of the Auto Idle Stop function and then failed to restart promptly when I attempted to proceed. On several occasions, while stopped at red lights on major roads and highways, the vehicle stalled and took a considerable amount of time to restart.

The delayed restart exposed me and my passengers to the risk of rear-end collisions and other accidents.

This seeping spool valve is a manufacturer’s defect.”

The vehicle mileage was 117,000 at the time of purchase; however, the title listed the mileage at 14,580. The Department of Motor Vehicle reported that the actual mileage as 214,000.”

“On Wednesday night, the battery light initially came on and after a few minutes the van had this burning smell so I pulled over and the alternator was on fire. I put it out with several bottles of water from papa John’s. Today, at Boyd Honda in Oxford said in the diagnosis that there was a sweeping spool valve that had leaked which must have caused the alternator to blaze because this is a manufacturer’s defect from Honda.”
