What owners report
All 27 complaints about the 2026 Odyssey in this group were filed between June and October 2026, and nearly all describe the same failure. The Auto Idle Stop system shuts the engine off at a red light or in stopped traffic. When the driver releases the brake, the engine does not restart. In many cases the transmission shifts itself into Park, and the dash tells the driver to press the brake and the start switch or select Drive, but that does not work. The van stays disabled in a live traffic lane until the driver turns it fully off and restarts it. That sometimes takes seconds and sometimes up to half an hour. Owners describe the same sequence independently. Several report repeat failures on low-mileage vans (about 6,000 to 12,000 miles). Complaints are rising fast: 2 in June, 13 in October. The same complaint theme is also surging on the 2024 Odyssey (50 complaints) and the 2025 Odyssey (260 complaints) and is active on the 2020–2023 model years. Whether those complaints describe the identical failure has not been established. Two owners say a federal engineering analysis (EA25-004) covers this failure on 2018–2025 Odysseys. No crashes or injuries are reported, but several owners describe close calls in traffic. No recall for this vehicle covers the problem. The root cause is not established. Candidates suggested by the complaints include the battery or charging system, the starter, and control software.
How it fails
The vehicle is stopped or nearly stopped, usually at a traffic light, with Auto Idle Stop active. The engine shuts off as designed. When the brake is released, the engine does not restart, or it cranks briefly and dies. The transmission often moves to Park on its own and will not shift back to Drive. A dash message tells the driver to press the brake and the switch or select D, which does not help. Some owners report the battery warning light, all screens going dark, or clicking while trying to start. Recovery requires a full manual shutdown and restart, after a delay ranging from seconds to about 30 minutes. One owner says restarts from idle stop had become slow and labored before the first full failure. Another describes struggling restarts at the next few lights after a failure. Failures recur, often several times in a week, and stop when owners switch Auto Idle Stop off. Dealers often cannot reproduce the problem and find no fault codes.
Safety risk
The van becomes immobile without warning in an active travel lane, intersection, exit ramp or highway stoplight, sometimes with children on board. This exposes occupants to rear-end and cross-traffic collisions. Most owners describe the risk of being struck. Several describe close calls, including one owner who rolled across a lane line in a dead van and braced for impact at a highway stoplight. Because the failure happens at or near a stop, the main danger is being stranded in traffic, not losing steering or brakes at speed. No crashes, injuries or tows have been reported.
Findings and the complaints behind them
Many independent owners describe the same sequence: Auto Idle Stop shuts the engine off at a stop, the engine fails to restart when the brake is released, and a manual shutdown and restart is needed.
NHTSA complaint numbers: 11773429, 11772897, 11771941, 11770476, 11769672, 11768789, 11765543, 11764602, 11762021, 11759963, 11750877, 11744414, 11750598
In many cases the transmission shifts itself into Park, or cannot be moved out of Park, until the vehicle is fully restarted, even when the driver follows the dash instructions.
NHTSA complaint numbers: 11773558, 11773577, 11771941, 11768782, 11764598, 11764602, 11743032, 11770476
Several owners report signs pointing to the electrical or starting system: the battery warning light, all displays shutting off, clicking while trying to start, or a completely dead electrical system at the light.

Restarts after a failure can take a long time: about 10 minutes, about 30 minutes during which the van could not even be shifted to Neutral to push it, and several minutes in other cases.
NHTSA complaint numbers: 11773577, 11764140, 11752324, 11762021, 11763755
One owner reports a warning sign before the first full failure: for some time beforehand, restarts from idle stop had been slow and labored.
NHTSA complaint number: 11771941
The failures happen on new, low-mileage vans and recur: about 6,000, 8,000, 11,900 and under 12,000 miles. Owners report 3 to 7 occurrences, including four in one week.
NHTSA complaint numbers: 11771941, 11772897, 11768789, 11768782, 11759963
Dealers often could not reproduce the fault or found no codes. In one case dealership staff saw the failure twice during a road test and replaced the battery, telling the owner this was a diagnostic step and not a confirmed fix. Two owners say their dealer told them it had received many similar complaints.

Two owners say the shutdown at a stop is different from normal Auto Idle Stop operation: the van turns off completely and must be restarted manually. A third owner describes the engine shutting off while the van was still rolling to a stop, after which it could not be restarted right away.
NHTSA complaint numbers: 11772892, 11772897, 11773577
Complaints are rising quickly: 2 in June, 3 in July, 2 in August, 7 in September and 13 in October 2026. The same complaint theme is also surging on the 2024 Odyssey (50 complaints) and the 2025 Odyssey (260 complaints), neither of which has a covering recall, and is active on the 2020–2023 model years. According to two owners, a federal engineering analysis (EA25-004) covers this failure on 2018–2025 Odysseys but not the 2026 model year.

Open questions
- What is the root cause: the 12V battery or charging system, the starter or its relay, or the software that controls idle-stop restart and the automatic shift to Park?
- Did the battery replacement on one owner's van stop the failures?
- Do complaints about the 2024–2025 Odysseys describe the same idle-stop failure to restart? Is it the failure under the engineering analysis owners cite for 2018–2025 Odysseys, and will any remedy be extended to the 2026 model year?
- Do the complaints describing a full shutdown at a stop or while slowing down (rather than an idle-stop failure to restart) have the same cause?
- How often does the problem continue when Auto Idle Stop is switched off?
