| Engine And Engine Cooling problems |
The auto idle/stop caused my engine to stall not once but twice in the past few weeks while on a major highway. Light turns green and my car won't start back up. I have to let the car sit for a second then restart the car while traffic is flying past me on this highway. Absolutely ridiculous that my brand new car is having these issues and that I am unable to turn this feature off permanently.
My 2026 Honda Odyssey was stopped at a traffic light with auto idle stop engaged. When traffic was ready to move, the engine appeared to restart for about half a second and then shut down. The vehicle then shifted itself into park and would not resume normal operation. The battery warning light was illuminated. Pressing the engine start/stop button caused all of the screens/displays to turn off briefly, but they came back on in the same failed state. The vehicle was disabled in traffic at an intersection. The component or system that failed appears to be the auto idle stop / engine restart system, possibly involving the starter, starter relay, battery/charging system, or engine control software. The vehicle is available for inspection upon request. My safety and the safety of others were put at risk because the vehicle unexpectedly failed to restart and became disabled while stopped at a traffic light, creating a traffic obstruction and risk of being struck from behind or causing other drivers to maneuver around the vehicle. The problem has not yet been reproduced or confirmed by a dealer or independent service center. Unknown whether diagnostic trouble codes were stored. The vehicle/component has not yet been inspected by the manufacturer, police, insurance representatives, or others. There were no warning lamps, messages, or symptoms prior to the failure that I noticed. The battery warning light appeared after the engine shut down and the vehicle would not restart normally.
