2024 Honda OdysseyRecalls, problems, MPG & safety

“While driving today at about 30 mph, the minivan suddenly braked on its own—despite there being no obstruction ahead—and began beeping. The word "Brake" appeared in large letters in the center of the panel, flashing, before suddenly releasing. My wife and I both suffered whiplash from the incident. There was nothing in front of the van; the only thing nearby was some cars parked on the curb along the side. My wife told me this has happened a couple of times before, and she reported it to Honda of Tomball. I'm very concerned that if we're driving at highway speeds and there are vehicles on both sides of our lane, this issue could occur again, and we could have a serious safety problem on our hands. In addition to this, we've been experiencing another issue: the van suddenly shifts into park when we come to a stoplight. This has happened three times. Yesterday they replaced the battery, but they still suspect it could be a starter issue.”

“Engine fails to restart after Auto Idle Stop - stalled in traffic twice on consecutive days. On XXX around noon, at [XXX], I was first in line in the left-turn lane at a red light, with my [XXX] daughter and another adult passenger aboard. The Auto Idle Stop system shut the engine off. When the green left-turn arrow came on, the engine did not restart and a stall warning appeared on the dash. I had to confirm the van was in Park with the brake applied, turn the vehicle completely off with the start/stop button, and press the start button many times before the engine started. The van sat stalled at the front of the turn lane, blocking traffic, for roughly 60 seconds during the green arrow. The night before, XXX around 11 pm, the same failure happened in the left-turn lane on [XXX]: the engine shut off at the red light under Auto Idle Stop, did not restart when the green arrow came on, and I was stalled in traffic for roughly 60 seconds going through the same restart process. Since about late XXX the engine has also at times restarted roughly after Auto Idle Stop, even when it does not stall. I could not read the exact warning message because I was stalled in…”

“My 2024 Honda Odyssey repeatedly failed to restart after the automatic idle stop system engaged at traffic lights. On numerous occasions, the engine shut off normally but would not restart when I attempted to resume driving. I had to shift into Park and manually restart the engine before continuing. This happened regularly and created a safety concern because I could become stranded in traffic with my children in the vehicle. I eventually began manually disabling the automatic idle stop feature every time I drove because I was afraid the vehicle would fail to restart. I reported the issue verbally to a Honda dealership employee during a previous service visit and was advised to disable the automatic idle stop feature rather than continue using it. In October 2026, at approximately 21,000 miles, the vehicle displayed a low battery warning. Several days later, it completely failed to start after stopping at a gas station. Three separate jump-start attempts were unsuccessful. The dashboard lights and audio system worked, but the power windows stopped functioning. An authorized Honda dealership diagnosed a completely failed starter. The service advisor stated that…”
