2023 Honda Odyssey problems

“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.”

“My 2023 Honda Odyssey, VIN [XXX], has developed an unusually loud noise from the engine compartment when I press the accelerator. The vehicle was purchased in XXX and currently has approximately 78,800 miles. An independent mechanic inspected the vehicle and did not identify an internal engine problem. The mechanic suspects that the high-pressure fuel pump may be the source of the abnormal noise, but this has not yet been confirmed by a Honda dealership. I am concerned that the noise could indicate a developing fuel-system defect and would like this issue documented and reviewed for any potential safety implications. I request that NHTSA investigate whether similar reports involving the 2023 Honda Odyssey indicate a defect that may warrant a safety recall.”

“After stopping the car in a left turn lane in the intersection, the car engine, dash board and infotainment system shut down. No warnings or other items appeared, the car died. After scrambling since it put traffic to a standstill, I shifter to park and returned on the car. Which worked and allowed me to continue. This happened again 1 week later while at a red light.”

“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…”

“I was pulling into a parking spot with my foot on the brake. My 2023 Odyssey van accelerated instead of braking. There is also supposed to be an auto car warning & braking if you are about to hit a car in front of you. None of this happened! In fact, it crashed into the car in front of me. As soon as it started to accelerate, I released the brake and reapplied the brake as hard as I could. It still hit the car in front of me. It didn't look like there was any damage to their car, but I was very shaken up and now I am worried this will happen again. It happened today, April 18, 2024. My mother was in the car and was as shocked and stressed as I am as the van went from very slow to fast. My body is still shaking. I haven't had it inspected yet. I have an appointment on May 1, 2024, to go to Odonnell Honda. The woman receptionist in the service area said I may have had my foot on the gas. I did not because when I pull into a parking spot, I always have my foot on the brake and go in very slowly. As a brand-new van, I am very alarmed and very nervous it could happen again.”

“The remedy for Safety Recall 23V-431 (MOST bus FAKRA connectors), performed 8/2023 at Joyce Koons Honda (Manassas, VA), has failed. The recall's stated safety risk, rearview camera failure when MOST communication is lost over 20 seconds, now occurs regularly on my vehicle. Symptoms began early 2025 and have worsened: intermittent loss of the rearview camera in reverse, infotainment reboots, and speaker popping (the warning signs listed in the Part 573 report). On [XXX] the infotainment system and backup camera were unavailable for over 50% of a long drive. Vehicle logs show 822 MOST network signal-loss events from [XXX] to [XXX] (avg ~15/week), predominantly "Tuner_Amplifier_Unit SUDDEN_SIGNAL_OFF" and "Meter SUDDEN_SIGNAL_OFF", the exact failure mode the recall remedy was meant to correct. I can provide the log data (chart and CSV). I reported the recurrence to the dealer on 5/31/2025; they said they could not reproduce it, and vehicle logs were cleared up to that date. I opened American Honda case #[XXX] in 10/2025 and escalated as case #[XXX] in 6/2026. On 7/1/2026 an American Honda representative told me Honda cannot authorize service without a dealer…”
