2021 HONDA ODYSSEY Complaints

Component or System Failed: Idle Stop System – The vehicle completely shuts off and requires a full restart at red lights or when stopped for several minutes. Safety Risk: The vehicle shutting off unexpectedly in traffic poses a serious safety hazard to both occupants and nearby drivers, especially when traveling with young children. I am genuinely fearful for our safety — particularly at red lights, where the risk of being rear-ended is high. There are numerous reports online of this same issue occurring in Honda Odyssey vehicles, indicating a wider safety concern. Reproduction of Issue: I have contacted both Honda and the dealership, and no effective solution has been provided. This vehicle is not safe to operate under these conditions. Inspection: The issue has been inspected by the Honda dealership, but no permanent resolution has been offered. Warning Lamps/Messages: There were no warning lights, messages, or alerts prior to the failure. The vehicle shuts off without any prior indication. Assessment of Cause: The problem appears to stem from a malfunctioning Idle Stop system, potentially related to the electrical or battery system. I understand that Honda has received multiple similar complaints from other Odyssey owners experiencing the same dangerous issue.

The contact called the local dealer, who stated that parts for the recall repair were sent to the dealer sporadically.

The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The contact had not experienced a failure.

I hear a popping/crackling noise from the speakers then I get complete network loss for my backup camera, my dvd player, my clock, maps etc.System does a report after 5+ minutes. Message displayed before everything goes black is Network Connection Lost and MOST Net Off. This issue is ongoing and seems to happen now every day sometimes multiple times in a driving session. It just started about 2 weeks ago. There is an active recall for this exact issue for 2021 Honda Odysseys but my VIN does not seem to be included.

My van is braking when there are no cars or dangers in front of it. Sometimes there's a metal plate on the ground or speed bump when it brakes. Other times there's nothing in front. The car slams on the brakes and I cannot override it with the gas pedal. This puts my kids and I in danger of being rear-ended. This most commonly happens around 7:30am or 4pm when I'm taking kids to school or dropping off. I'm often in the carpool like or headed to the school when the car slams on the brakes. It's very frightening. The dealer cannot find an issue and cannot replicate the problem.

Dealership has been unable to complete recall repair due to parts being unavailable. The original recall is over 18 months old.

Vehicle lost power resulting in the vehicle automatically going into park and powering off while driving. This has happened multiple times. In addition, we will get strange electronic codes. Tested battery and systems successfully, but problem persists.

When attempting to restart from the autostop function (i.e. the fuel economy function), the vehicle fails to restart successfully. This has happened on multiple occasions. It is not a battery problem and I have had the battery tested and even replaced (by Honda) and the problem has continued. The vehicle will stutter, stall or even completely shut down. This has happened when I have been at intersections and on busier roads or even in traffic on the highway. Its very concerning to me and seems extremely unsafe. No warning signs come in this scenario until the vehicle shuts down and the regular dash light engages indicating the engine is inoperable. I have today's date below but this has been happening consistently the last several months.

Can has been making a popping noise that can be felt in the steering wheel for 2 years. Honda has told me nothing was wrong after taking it in 4 times. Now my car keeps stalling at lights, sometimes it takes a while to get it to restart, and they can not figure out why. They keep saying the battery is fine and diagnostics finds nothing.

Vehicle applied brakes for no reason. Lost ability to see reverse camera during backing up. Half of the instrument cluster went dim to become barely visible. Radio screen freezes randomly. Engine cuts out or shudders intermittently.
