2018 Honda Odyssey problems

ELECTRICAL SYSTEM

A warning for Power Tailgate Problem keeps coming up. It tried to open multiple times while driving, beeping at us. It wouldn’t open with the buttons at all. We had to manually open and close it. This makes the second time it’s done it. And it always has to do when it rains. Honda knows this is a well known issue with their odyssey’s and it needs recalled. The dealership wants us to pay for a well known issue. We had a friend with the same year odyssey and the same thing happened but their tailgate completely opened a few times while driving.

SERVICE BRAKES

My Odyssey randomly began displaying all of the ADAS warning messages: The Brake System indicator light comes on, Forward Collision Warning, Lane Departure Warning, Lane-Keeping Assist, Auto High Beam System error, etc. These came on beginning 7/25/26 and have come on everyday since causing the entire ADAS system to be inoperable. There have been a few days that they didn't come on immediately. I have had a few days where they came on half-way through my drive. This is a safety issue due to a defect in either the front camera or wiring to it, a nuisance, and something Honda needs to correct. It seems to be way too common of an issue according to my research. There hasn't been any damage to the van and no reason for these to come on. I have done research and see this has happened to many people. The replacement camera is costly as well as the calibration. Therefore, I haven't taken it to the dealership but I have discussed the issue with them. They agree that the camera is getting too hot and failing, which is causing the errors and of course all of those safety features fail simultaneously.

UNKNOWN OR OTHER

2018 Honda Odyssey Elite I am reporting an unresolved issue stemming from a failed recall remedy for NHTSA Safety Recall 23V-431 (Honda TSB 20-049) regarding the MOST bus fiber-optic network. My vehicle has been taken to an authorized Honda dealership twice to receive the official recall repair (replacing the FAKRA network connectors). Despite these two repair attempts, the network defect continues to escalate.The vehicle experiences sudden, violent, and near-constant loud popping and clicking noises through the audio speakers while driving. This occurs both at random and predictably when driving over bumps. Following the increase in these network pops, the vehicle's Blu-ray player completely failed and stopped working. Furthermore, the central infotainment screen frequently freezes, reboots, and displays an "Audio Connection Lost" error message, which also cuts out the FM radio tuner entirely.Crucially, this fiber-optic network failure recently caused a total loss of the digital instrument cluster and speedometer while driving. While this complete cluster blackout has only occurred one time so far, it presents an unpredictable and dangerous safety hazard, as I am left with no knowledge of my current speed or critical vehicle safety alerts while in motion.The manufacturer’s standard recall remedy of swapping plastic connector clips is ineffective for my vehicle. The recurring failures after two repairs indicate a permanently compromised factory wiring harness or a damaged network module that is continuously dropping the signal. The manufacturer needs to authorize a thorough diagnostic and full harness/module replacement to permanently resolve this safety defect before the instrument cluster fails again.

ELECTRICAL SYSTEM

Early in a driving session, the accelerator pedal, when applied pressure, will not rev the engine and provide power to the wheels for 1-3 seconds. This issue happens once or twice in a driving session and then doesn't do it again until a future driving session. It is random and doesn't happen every session. This issue causes me to have concerns entering traffic, particularly left turns, as I am unsure if the vehicle will accelerate when needed to safely enter traffic. I have had Service Bulletin 19-124 completed on my vehicle and it did not fix the issue.

LANE DEPARTURE: BLIND SPOT DETECTION

Our van recently started flashing multiple warning lights every time we started it up. These include "Collision mitigation system problem", "auto high-beam problem", "road departure mitigation system problem", "lane keeping assist problem", "adaptive cruise control problem", and also alerts that there is an issue with our brakes. We took the van into our local Honda dealership and were told the ADAS camera was broken and would need to be replaced. We were told this would cost $2,733 and that there's a chance we will also have to replace the windshield (which is physically fine) for another $1200. The camera breaking is not normal maintenance or expected due to wear and tear. There is nothing physically wrong with our windshield, we have had no accidents, we have kept up on all needed vehicle maintenance. It's my understanding the location of the camera is simply causing it to overheat and blow out the electrical system. Additionally concerning is that even if I did have the money to fix the issue Honda does not have any cameras available. They are on backorder. It means as a driver to three small children I have to assume the nonstop alerts are all benign for at least a month. In the off chance there is a true safety concern such as brakes malfunctioning, I will not know as the alert system is going off at all times.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

while driving at 35 mph a vehicle well ahead of me made a left turn exiting the roadway. My vehicle suddenly applied the brakes even though there was no longer a vehicle in my path. I tried to increase the accelerator, but the vehicle was slow to respond to this. luckily there was not another car directly behind me. This exact problem had occurred many time previously.

POWER TRAIN

While driving the car lurches as it shifts gears. This had gone on for quite some time but no codes have been thrown. This last time the car lurched so badly at the beginning of acceleration that I thought it was going to stall. It did not, but lights began flashing on the dash and when codes were (finally) thrown I was told I needed a new transmission altogether.

FORWARD COLLISION AVOIDANCE: WARNINGS

Front camera failure shut off multiple safety features. Confirmed by the dealership service department. Safety features shut off adaptive cruise control, lane keeping assist, collision mitigation system, road departure mitigation system and blind spot info system. Driving this car under 43000 miles with multiple safety features off with messages flashing is stressful, distracting, uncomfortable and unsafe especially this car is mainly used for children. The worse part is that the dealership service department can not fix the problems because the part is back ordered. We have to continue to use this car in this unsafe condition.
