The contact owns a 2026 Honda Odyssey. The contact stated that while driving on several occasions at various speeds, the blind spot monitor became inoperable with the message "blind spot information systems failure - see dealer" displayed. The contact also stated that while in the driver assist mode, the message "system could not be retrieved - please try again" was displayed. The vehicle was taken to a dealer where it was determined that a systems update was needed but was not currently available. The vehicle was not repaired. The manufacturer was notified of the failure and a complaint was filed. The failure mileage was 6.
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.
