2023 Honda Odyssey Electrical System

Around Dec 2024, the central control screen started blacking out. At first, it would black out and then the screen will come back on randomly. We took the car to Tempe Honda service center, and the technician was able to reproduce the problem, and it's covered under warranty. However, they had to order, but they didn't anticipate that it would be in back order. A couple months later, we checked on the status and found out that it was on back order and there is only one manufacturer, so it could take a few more months. We kept on calling to check on the status, and the anticipated back-fill date kept on pushing out. Finally, the screen went completed black and wouldn't come back around Aug 2025. We called Tempe Honda, and the service manager suggested us to call American Honda Motor. We did, and a case was open with American Honda Motor around 10/17/2025. American Honda Motor has been providing weekly update to us, however the update has been the same, which is that they are waiting for ETA on the release date for the part. We wrote an email back on 11/20/2025 with our concerns around safety due to this defect. They called on 11/26/2025 and suggest us to file a complaint with NHTSA. Our concerns in the email include: 1) it's the central control for a lot of the functions including navigation (which we can't update because the screen is broken, and the warranty period to do so will soon be at an end); 2) It's being used when we back up our car. With the defect screen, the back-up camera is useless. This poses potential danger as we pull out of a busy parking lot, such as at school when we drop off and pick up kids. it's very difficult to back up without the screen especially when there are large vehicles parked next to us; 3) To have customers with an essential part of the car being defective for a year is unacceptable. This problem needs to be fixed ASAP. Thank you!

Engine shut off in traffic after Auto Idle-Stop failed to restart. While stopped at a red light with Auto Idle-Stop active, the engine shut down normally. When I released the brake to proceed, all electrical power dropped—cluster went dark, accessories reset, and the engine did not crank. Vehicle coasted dead across the intersection and required a full key-cycle to restart, exposing my family and surrounding traffic to a collision risk. Component that malfunctioned Dealer diagnostic later the same day showed the 12-V battery-current sensor reporting an internal resistance spike from 3 mΩ (normal) to 25 mΩ (fault), which commands the powertrain ECU to inhibit Idle-Stop restart (“Idle-Stop Inhibit – Large battery internal R” flag). An AGM load test confirmed the battery itself is healthy (958 CCA). Reproducibility / confirmation The stall occurred twice on public roads. At the dealer, the fault could be reproduced in the data list: resistance value jumps whenever the negative-terminal sensor is jostled. Inspection status Vehicle was inspected by the franchised Honda dealer; screenshots of the diagnostic session and the Midtronics load-test slip are available on request. Manufacturer has NOT yet repaired the sensor; dealer demanded an unnecessary battery purchase first. Warning indicators No MIL or warning lamps illuminated before the stall. After the first stall, a brief “Auto Idle-Stop System Problem” message flashed but cleared on restart. Risk Loss of propulsion and power steering in the middle of an active intersection without warning. If this sensor defect is common, any similar 2022-24 Honda minivan/SUV with Auto Idle-Stop could stall in traffic. Component is still installed and available for inspection. Filed report with FTC (report #188697846).

The infotainment screen goes in and out. The screen makes crackling sounds and just goes blank. Causing problems with gps, sound, back up camera, emergency help feature etc. nothing functions. Extremely dangerous. When you rely on your GPS and the entire system malfunctions it is so dangerous. Honda had recalls on previous models for the same feature. They need to extend the year to 2023 models as well for faulty wiring. They are trying to charge thousands to replace a system that they have admitted has these issues at no fault of the consumer.

The car appears to power up on its own even after it has been shut off. I have noticed that the car was on even after I turned it off, so I have been even more diligent about making sure it was turned off. One day I turned off the car. About an hour later, I heard the speakers in my car blaring. When I was finally able to reach the car the sound was off and the car was black. I didn't even get a chance to open the door and turn it off. It just shut down on its own. Yesterday, when I went to start my car, there was a message that the battery was low. As if the car had been on for a while. But when I got in the car it wasn't on. This appears to be a known problem from other Odyssey owners. Specifically I am seeing issue with 2018 models. However mine is a 2023 model.

Yesterday we were in our minvan (I had not entered yet and was standing outside the fornt passenger door but wife, children, and dog were inside. My daughter mashed the button to close the power sliding door on the right side of the van but did not notice that the dogs tail was wagging near the door entrance. All of a sudden I heard loud screaming and I opened the door on the right side. She was bleeding and in tears and said that the power door had closed on our dog's tail. I am a physician so I provided first aid. My concern is that when we bought the van we aksed about the power doors because we were concerned about them possibly closing on someone or something since they can be closed by multiple passengers. The salesmen assured us that the doors would not close on anything or anyone and would reverse if they met any resistance. Well the door completely closed all the way in this case despite the dogs tail sticking out of it.
