2023 Honda Odyssey electrical problems

Filed Oct 18, 2026 · Electrical · CA

My 2023 Honda Odyssey (approximately 38,000 miles) has an intermittent no-crank/no-start condition. Pressing the push-button start produces no crank at all; the engine only starts on exactly the fourth press, consistently. The battery was tested and is good. The condition worsened noticeably after a high-pressure car wash, suggesting moisture intrusion. This matches Honda Technical Service Bulletin 23-023 ("Engine Does Not Crank"), which covers 2018–2023 Odysseys and attributes the defect to water entering the starter motor. The vehicle is about 2,000 miles past the 36,000-mile bumper-to-bumper warranty. I am concerned the condition will degrade without warning and leave my family — including small children — stranded. The vehicle is scheduled for diagnosis at Tracy Honda in [XXX] on XXX. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2023 Honda Odyssey experienced a serious malfunction of the Auto Idle Stop system at approximately 32,987 miles. While stopped at a traffic light, the engine automatically shut off as designed but failed to restart when I attempted to move forward. This created a dangerous situation because my vehicle was unable to move when the traffic light changed, potentially putting me, my entire family at risk of a rear-end collision. The vehicle's battery had been replaced only a few months earlier, so this problem occurred despite having a relatively new battery. After researching the issue online, I found numerous reports of similar Auto Idle Stop failures involving Honda Odyssey vehicles. This appears to be a recurring safety concern rather than an isolated incident. To my knowledge, there is currently no applicable recall providing a free repair for my vehicle. I believe this is a significant safety defect that Honda should investigate and address at no cost to affected owners. A vehicle should not unexpectedly fail to restart in active traffic, regardless of its age or mileage. I am requesting that the federal safety agency investigate this issue and determine whether a safety recall is warranted.

The infotainment screen will go blank and will no longer show the backup camera at all. The FAKRA recall was performed at the Honda dealership when I first purchased the car new. I did not have any significant issues until around July of 2026. First, the speakers will crackle with static noise, then the volume cuts off completely, then the screen goes black and message pops up "Network Communication Lost, MOST Net Off". Then the screen will completely go blank and the backup camera will not turn on when in reverse. For the past two weeks the screen/radio/backup camera does not turn on at all. Completely black screen the entire time while driving, even with repeated power cycles. This is obviously related to the FAKRA recall that did not fix the issue. This is a major safety issue for a large, family vehicle to not have a functioning backup camera; something that has been federally required since 2016. A new recall needs to be issued so that the issue can be fixed correctly.

Seems like due to the auto idle, it makes the engine idle so low that it dies- my car died in middle of the road- the first time, I had it jumped, and mechanic said it was a fluke, second time, despite the testing not showing any issue, he said we can try to replace the battery, so we did, but 6 weeks later my car died, and it took 5 attempts to get it to restart with the external battery pack! each time there was NO issue with the electrical system- my A/C was running fine, the whole dashboard showed up fine. Seems like according to a class action suit in california this is an issue Honda KNEW about! People now know to press the Auto-off button so the car does not auto idle- but this needs to be done EACH time, or you will end up KILLING your engine! How is this allowed to be sold?? I was stuck in MIDDLE of a busy street with my DAUGHTER in the car!!!!

When we are idling (at a red light), the engine will suddenly stop. We believe this is the feature of the start-stop system used to save gasoline. We will then have to completely restart the car as the car has been turned off. This creates a huge safety hazard at intersections. We have asked Honda about it twice now and currently replacing the starter. Our car is a little over 3 years ago with about 40k miles. The starter should not be failing at this point and we believe it is due to this start stop issue. The starter cost us $1400 in a car that is just over 3 years old with about 40k miles.

While driving from [XXX] to [XXX], all of the safety systems started to fail. We had driven about 45 minutes from our starting point. As the system started to fail, they would flash across the screen on the dashboard saying each one that was failing. We pulled over to the side of the road, and my husband popped the hood and flames started coming out of the hood, closest to the dashboard and windshield. We called 911 and by the time they reached our location, the entire vehicle was engulfed in flames. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am submitting a formal safety complaint regarding a failure of the power tailgate system on my 2023 Honda Odyssey. The issue involves water intrusion into the liftgate control system, which has resulted in corrosion and subsequent failure of the power tailgate. This malfunction presents both a safety concern and a significant reliability issue, particularly for a vehicle of this age and mileage. What is most concerning is that this does not appear to be an isolated incident. There is a documented history of similar failures in Honda Odyssey vehicles, including prior class action litigation related to tailgate and electrical system defects. Despite this, the issue does not appear to have been adequately addressed or corrected in newer models, including the 2023 version. My vehicle has approximately 30,500 miles and is only slightly outside of the warranty period. I was explicitly assured at the time of purchase that the vehicle was reliable and that the manufacturer would stand behind it. However, I have since been informed that this repair will not be covered, despite the apparent design flaw and known history of the issue. A power tailgate failure is not merely an inconvenience—it can pose safety risks, especially when transporting passengers, children, or cargo. A malfunctioning liftgate can fail to open or close properly, potentially causing injury or limiting access in urgent situations. I respectfully request that the federal safety agency investigate this matter further, as it appears to be part of a broader pattern affecting Honda Odyssey vehicles. Consumers should not be responsible for costly repairs stemming from known defects that have not been properly resolved. Thank you for your time and attention to this matter. I am happy to provide any additional documentation or details if needed. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The power tailgate control unit (part #74970-THR-A12) failed on my 2023 Honda Odyssey at approximately 46,000 miles and 3 years of age. The tailgate stopped functioning entirely. Upon removing the interior rear trim panels to diagnose, I discovered the failure was caused by water intrusion into the rear body of the vehicle. Behind the interior panels I found: significant rust on interior sheet metal, green corrosion coating the power tailgate control unit, dried water stains showing pooled standing water that had evaporated over time, and clear evidence of repeated slow water exposure over an extended period — not a single incident. The vehicle has no rear windows that open and no exterior damage that would explain the water source. The symptoms and damage pattern match the class action Dubrosky v. American Honda Motor Co., [XXX] , which alleges defective polyurethane rear body seam sealant in 2018-2021 Honda Odysseys allowing water to leak into the rear driver's side panel and destroy the power tailgate control module. My 2023 exhibits identical symptoms, raising the question whether the same defect extends to later model years. SAFETY RISK: The class action documents that this defect has caused tailgates to open or close unexpectedly while the vehicle is in motion, fail to latch, short-circuit, and in some cases cause fires. Items in the cargo area can fall out during driving, creating road hazards for other vehicles. My tailgate failed completely; I consider myself fortunate it failed closed rather than opening in motion. The damaged components are available for inspection. The vehicle has been inspected and photographed by Pohanka Honda of Salisbury, MD, who confirmed the damage but denied warranty coverage. No independent inspection has occurred. WARNINGS PRIOR TO FAILURE: None. No dashboard warning lamps, messages, or symptoms appeared before the tailgate stopped functioning.
