2020 HONDA ODYSSEY Complaints

Car was stopped in traffic and has a feature that shuts off the engine when stopped (in Drive but with brakes pressed). When trying to proceed forward car shuts down with numerous errors and does not start back up for 5 minutes. Cars are honking and having to drive around us. Eventually was able to get the car running and moved to a safe area. Errors car displayed included: blind spot info system problem and transmission problem

The idle stop caused my car to turn off on the highway while I was stopped in traffic. Unfortunately, I was the last car in the line on the highway and the truck coming behind me was coming at a rapid rate of speed. Thankfully, the same issue had happened to my son the week before and he was able to tell me that putting the car in park and turning it off and back on would fix the issue. There is a service bulletin 21-013 related to this issue but not a recall. This is a safety issue that needs to be addressed.

SOMETIMES (NO DISCERNIBLE PATTERN) AFTER STOPPING AT A RED LIGHT OR A STOP SIGN, THE CAR SHUTS OFF AND WILL NOT RESTART FOR SEVERAL MINUTES. THE HONDA SERVICE CENTER AT THE DEALER WHERE WE LEASED THE CAR SAID THEY HAVE HEARD OF SIMILAR PROBLEMS WITH NEWER MODEL HONDA ODYSSEYS AND HONDA PILOTS BUT THERE HAS BEEN NO FORMAL RECALL. THIS IS A CLEAR SAFETY HAZARD. THE BATTERY HAS BEEN TESTED AND IT IS FINE.THE MECHANICS CANNOT FIND ANYTHING WRONG WITH THE CAR.

Auto shutoff feature regularly fails when attempting to restart the engine. It may delay the restart or put the car in park and not allow it to restart for over 30 seconds. I was stuck in stop and go rush hour traffic. The engine would not restart, leaving the car stranded in the center lane for over a minute while attempting to get the car to start and in drive.

The contact owns a 2020 Honda Odyssey. The contact stated that he became aware that the VIN was included in NHTSA Campaign Number: 23V174000 (Visibility) however, the parts to do the recall repair were not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. VIN tool confirms parts not available.

While driving the infotainment system will go completely out. When this happens you lose all additional safety features (back up camera, lane notifications, etc). This also becomes a distraction to the driver as when the system goes out it make a loud noise or will have a continued crackling noise which is highly distracting to the driver. I have seen a number of complaints online about this issue and have experienced the outages almost daily while driving the vehicle.

Stopped at red light. System to stop the engine to save fuel engaged. When light turned green the car would not restart, stranding the vehicle at the intersection.

Auto engine idle shut off issue and yes it is available for inspection. Upon exiting stop/start events(auto shut off at stop signs/lights/parking lots), engine does not restart. instead, it shifts into park, lights up all instruments on display panel, and requires a manual restart. vehicle is dead until restarted, posing a hazard to occupants/oncoming traffic. This has happened to me 3 times over the last two weeks. Didn't document date of 1st incident. 2nd incident was 3/22/23. 3rd incident was 3/25/2023. Immediately taken to dealer service center for repair. Dealer told us they couldn’t replicate the issue, that there are no codes, and no service advisories. We were told there was nothing they could do and to just turn off the feature when driving. The only one to inspect the vehicle was the dealer service center. No warning at all. Car just doesn't start and driver is left sitting and helpless in active traffic until the car can be restarted.

The contact owns a 2020 Honda Odyssey. The contact stated while the vehicle was at a complete stop at the traffic light, the collision mitigation braking system (CMBS) warning light illuminated and a message indicating to shift to park(P) was displayed. The contact shifted to park and shifted back into drive(D); however, the vehicle failed to accelerate. The contact stated that he turned off and restarted the vehicle and was able to drive to his destination. The vehicle was taken to the local dealer however, the failure could not be duplicated. The contact stated that the failure persisted. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 32,000.

On 18 January 2023 the tailgate on our 2020 Odyssey refused to open. Neither the inside switch nor the outside switch does anything. I crawled in the back and checked the fuses and both are good. I also discovered that the emergency tailgate release did not function. Took it to the dealer, Greenway Honda in Florence, Alabama, an hour from home, and they weren't able to find the fault with a cursory check and a reboot of whatever computer system is applicable. They said they need to keep it for at least a half day and "really tear into it." But we could not leave the vehicle at that time, having no transportation home. Eventual diagnosis determined the tailgate control module, the tailgate closure motor, and the tailgate latch had all failed. Parts were on backorder and no estimate on availability. After I contacted Honda corporate the parts suddenly became available at the dealership within a few days. Repairs were effected on 27 February at Greenway Honda, Florence, Alabama. We were without the full use of our vehicle for approximately six weeks. Occupants could become trapped in the vehicle if the front doors were disabled in a collision and electrical power was lost, rendering the sliding doors and the tailgate inoperative. The emergency release lever also would not function and this could trap occupants completely. Examination of the tailgate electronic control module shows water infiltration which conceivably shorted the closure motor and jammed the latch, making it impossible to open the tailgate. Photos of the failed electronic module were provided to the dealership and to Honda corporate. The failed parts are in my possession and are available for inspection.
