“The driver sliding door would not close and would sometimes reverse direction. Eventually, it failed completely and would not close. Dealership repair involved the rear door latch and motors and cost over $2600. Two weeks later and the passenger sliding door is doing the same exact thing. This is clearly a safety issue as I cannot be sure the door will not open completely while driving. The computer receives "door open" signal even while the car is off which drains the battery. I will not spend another $2600. Over $5000 to maintain a vehicle less than 5 years old for something as simple as the use of plastic components in a door latch is ridiculous and should be covered by Honda for choosing to use inferior components.”
“The contact owns a 2021 Honda Odyssey. The contact stated that while driving 50 MPH, the radio displayed a blank screen. In addition, the contact stated that while reversing, the rear-view camera turned on and off. Additionally, there was a cracking sound coming from the speakers. The dealer was contacted by phone and made aware of the failure. The vehicle was taken to the dealer, where it was diagnosed with rear-view camera failure. The contact was informed that an unknown recall repair was completed in 2023. The contact was informed that the repair was not covered under warranty, and a diagnostic test was suggested. The vehicle was taken to an independent mechanic, where it was diagnosed, and a split wire was found behind the radio. The manufacturer was contacted by phone, and a case was filed. The failure mileage was approximately 34,100.”
“Two intermittent problems began about one year ago at approximately 43,000 miles (current mileage approximately 48,000): 1) Rearview (backup) camera intermittently fails. When shifting into reverse, the display screen goes black or the camera image freezes. This causes a loss of rear visibility while backing up, creating a risk of striking a pedestrian or object behind the vehicle. 2) Audio system intermittently produces loud static and distortion across all audio sources (AM/FM radio, Bluetooth, etc.). This distracts the driver and can mask audible safety alerts. Contacted a Honda dealership regarding recall coverage for these issues; the dealership stated this VIN is not included in the recall. Neither issue has been repaired. The vehicle is available for inspection upon request. These symptoms match NHTSA recall campaign 23V-431 (Honda MOST communication coaxial cable recall — intermittent loss of MOST connection causing rearview camera failure and audio popping/crackling); the dealership stated this VIN is not included in that recall.”
“Mileage: 121000 When stopped and the auto idle initiated, we have had numerous incidents where the van has shutoff and required a restart. More recently, when the auto idle initiates, the entire engine turns off and the van has no power(car won't restart, can't get the car into neutral, sliding doors and tailgate won't open). I would then need to jump start the car with my portable battery. This has occurred 4 times thus far. Honda dealership had recharged the battery but it still died and required a start. Currently in the shop and my 120k extended warranty just ran out. Very disappointing.”
“The first problem I came across was Auto start. It always say temporary off because either I didn't press on the break hard enough or the Ac is running. Mostly it off saying it need to be charge and the company already put a battery in the car and it still say the same thing. The other thing that keep happening with the car is the screen that pop up the back camera and also control the air conditioning.it shut off and mos network failed and trun off and it keep going off and on. Im scared imma drive and it gonna shut off while driving already it hard at time using my back cameras since the screen work when it want to. I did talk to the dealership about the car and the problems since they said they check it and it was ok but I'm still having problem. I only had the car for 9 months and the problem start happening 2nd month with the Auto start and 5 months for the mos network fail within me having the car.”
“When coming to a complete atop, the engine switches off (the idle stop function), which is ok, but when I release the brake the engine often fails to restart. I’ve replaced the battery but this appears to be a common problem. It’s been happening more now at the end of summer when it’s hot for some reason. I was told there is a similar investigation open: EA25004”
