FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS, LANE DEPARTURE: ASSIST
My 2018 Honda Odyssey with just under 59,000 miles is showing the following warnings: - ACC - Adaptive Cruise Control Problem - Collision Mitigation System Problem - Auto High-Beam Problem - Road Departure Mitigation System Problem - Lane Keep Assist Problem. Using a code scanner, the ECU reports error U3000-49, which seems related to the Multi-Purpose Camera Unit used for all these functions. Given that this camera is used in the various safety features listed above, the current condition presents an unsafe condition for my vehicle, which has less than 59,000 miles of being driven.

POWER TRAIN
The contact owns a 2018 Honda Odyssey. The contact stated that while driving at various speeds, the vehicle would hesitate upon depression of the accelerator pedal as the check engine and several other various warning messages appear on the instrument panel. The vehicle was taken to a dealer for service; however, the dealer was unable to diagnose or duplicate the failure. The contact then stated that while driving at 70 MPH, the vehicle suddenly downshifted and failed to shift out of neutral(N). The contact pulled over and attempted to correct the failure; however, the vehicle shut off. Due to the failure, the vehicle was towed to the dealer where the diagnosed the vehicle with a failed torque converter and transmission. The manufacturer was notified of the failure and was given a case number. The vehicle remained in the dealer's possession and was not repaired. The failure mileage was approximately 80,000.

ENGINE
I own a 2018 Honda Odyssey 3.5L V6 and while my wife and 9 year old daughter were driving down the highway at 70mph that car decided to throw a rod throw the bottom of the motor leaving my family stranded on the roadside with no motor oil left in the car. This is a known issue for the 2018 Honda Odyssey but only for certain VIN numbers. I think it's pretty clear from all of the online complaints from this same year that it's not only those VIN numbers. We have always replaced the oil at 3,500 miles with Mobile 1 syntenic 0w-20 and always check the oil level to make sure none is missing. For the car to just throw a rod at 157k miles is pretty concerning as this will require a entire engine replacement out of pocket cost as Honda will not take ownership of this even though this year and model is known to have issues. I would like to see more VIN numbers added to their recall because this isn't fair to the people who buy a car for reliability and are left stranded on the roadside for a known issue they are not being forced to stand behind and make right. PLEASE HELP ME

AIR BAGS, SEAT BELTS
I was travelling on a two lane surface road with a speed of 45 mph, travelling at or below posted speed and just starting to slow to make a right hand turn when I encountered / wandered over the solid white line into a pothole at the edge of the road where there is no shoulder. Airbags on the passenger side including the sidecurtain and airbag inside the passenger seat deployed instantly. There was no collision and no deployment of the front passenger airbag or any other bags in the vehicle. There was an immediate call from Honda regarding the airbag deployment along with an automated notification to local police. Police in [XXX] responded and made a report and created a case number: #[XXX] I had a passenger in the front seat at the time who received a facial laceration, bruises to the right arm and hip. This is part of a known recall for this model and year of vehicle. Police and local dealership ( Casey Honda of XXX [XXX] ) have both confirmed visually that the airbags have deployed. No warnings, lights preceded the event. I just received the letter in the last few days regarding the recall. Honda has issued a case number for the incident: #[XXX]. I will be following up Honda for an inspection of other accident sensor and systems for safety which can be affected by the deployment.

ELECTRICAL SYSTEM
COMPONENT: Power Liftgate Control Module (PTG module). Vehicle is available for inspection upon request. WHAT HAPPENED: On approximately April 7, 2026, while driving in rain, a "Power Tailgate Problem" warning appeared on the instrument cluster. Following that event, all powered liftgate operation became permanently inoperable — interior button, exterior button, and key fob all failed. CAUSE: An authorized Honda dealer confirmed in writing (service invoice, May 1, 2026): "Power Liftgate Control Unit has corrosion from water leak." The water intrusion originates from defective factory polyurethane seam sealer on the rear drip rail — a known manufacturing defect on 2018-2019 Odysseys documented in Honda TSB MC-10152401. SAFETY RISK: The same water intrusion that destroys the PTG module is documented to cause the liftgate to open unexpectedly while driving, posing a direct hazard to occupants and other motorists. NHTSA is already investigating this issue across 2018-2022 Odysseys. WARNING SYMPTOMS: "Power Tailgate Problem" warning on instrument panel cluster appeared during rain exposure prior to full failure. MANUFACTURER RESPONSE: American Honda Motor Co. declined to cover the repair under goodwill despite the dealer-confirmed defect, an active TSB, and an ongoing class action lawsuit (2018-2021 Odysseys) for this exact issue. Honda has not issued a recall. Estimated repair cost: $691 (module) plus body seam repair.

ELECTRICAL SYSTEM
While the vehicle is in motion, it is loudly beeping that there is a problem with the rear tailgate and that it is open when it is closed. This is due to manufacturing defect wherein water is getting into the tailgate control module and ruining the electronics. This is making the tailgate unusable as it will not open and just reads off the error message. This is a well documented issue all over the internet on these vans and Honda should recall the vehicles to fix this.
