There are 2 owner-reported fuel system complaints for the 2024 Honda Odysseyin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
I am writing to formally report and complain about a serious safety issue I am experiencing with my Honda Odyssey related to the Auto Idle Stop feature. While the vehicle is stopped and Auto Idle Stop is engaged, the engine unexpectedly shuts down and, in some cases, does not restart properly when I attempt to accelerate. This has occurred after normal driving and also immediately after refueling. When the issue happens, the vehicle loses power completely for several seconds, creating a dangerous situation—especially in traffic, at intersections, or while making turns. This issue is not only inconvenient but also a significant safety concern. A delayed or failed engine restart can easily lead to accidents, particularly when quick acceleration is required. I understand that Auto Idle Stop is designed to improve fuel efficiency, but it should never compromise vehicle safety or reliability. I am aware that other Honda Odyssey owners have reported similar problems, which suggests this may be a known or widespread issue. I would like Honda to: Acknowledge this problem as a potential safety defect Investigate whether this issue is related to the Auto Idle Stop system, fuel system, battery, starter, or engine control software Advise whether there is an official fix, software update, recall, or service bulletin addressing this issue Provide guidance on how Honda plans to resolve this problem permanently Please let me know the next steps to have my vehicle properly inspected and repaired. I expect Honda to take this matter seriously, as it directly affects driver and passenger safety. I look forward to your prompt response
