Risk: A damaged parking rod can allow the vehicle to roll when parked, increasing the risk of a crash or injury.
Fix: Honda will notify owners, and dealers will ensure the battery terminal connections are secure and will update the TCU software, free of charge. Additionally, the parking rod effectiveness will be checked. The recall began May 31, 2019. Owners may contact Honda customer service at 1-888-234-2138. Honda's numbers for this recall are Z4J, Y4K.

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 101, "Control and Displays" and 111, "Rearview Mirrors."
Risk: Operating a vehicle without a functioning instrument panel or rearview camera display increases the risk of a crash.

Owner-Reported Issues (20 of 865)
Forward Collision Avoidance →3 issues
Your Honda Odyssey's windshield camera (part #36160-THR-A73) has failed, triggering a U3000-49 error code. This failure disables multiple safety features including collision mitigation, road departure warning, auto high beams, and adaptive cruise control. Dealership repairs exceed $2,000, and you may want to contact Honda about a potential recall since this appears to be a widespread issue affecting 2018 Odysseys.

Engine →3 issues
Your 2018 Honda Odyssey has been diagnosed with engine failure caused by rod bearing failure (rod knock) at 72,500 miles, despite regular maintenance. The dealer quoted $8,800 to replace the engine with a used one, and Honda Corporate denied your goodwill claim. Your vehicle is now completely inoperable and unusable for family travel.

While driving on the highway, your check engine light came on and off, and you heard what sounded like engine knocking. After pulling over, the engine suddenly seized and stopped when you slowed to 45 mph, leaving you unable to restart it or shift to neutral. The dealership found the engine had catastrophic internal failure and needed complete replacement at 126,000 miles. The issue may be related to a known Honda technical service bulletin (TSB 24-003) for connecting rod bearing failure, which your vehicle wasn't included in despite being from the affected year.

Over a year ago, my vehicles engine began ticking. On 12/14/2024, while driving the vehicle, it developed a rod knock, went into a limp mode and was towed back to our house. I eventually took the vehicle to Honda in Beaumont, Tx where they did an inspection of the vehicle and verbally told me it was the crankshaft, but would not provide me any documentation stating that.

Electrical System →3 issues
Your power tailgate isn't working, and water may be leaking into your vehicle's electrical system and draining your battery. This is likely caused by water getting into areas it shouldn't, which is damaging the electrical components that control the tailgate. The fix will probably involve finding and sealing the source of the leak, then replacing or repairing the affected electrical components and possibly the battery.

Your power sliding rear hatch has stopped working and is showing an error on your dashboard. Water is leaking into the electrical control unit behind the left rear panel, damaging the circuits and preventing the door from operating. In some cases, other owners have reported the rear gate unlatching unexpectedly while driving. The fix will likely involve replacing the faulty door seals and repairing or replacing the water-damaged electrical control unit.

Water is leaking from your roof rails onto the power liftgate control module, causing it to short circuit and malfunction. Your tailgate may open or close unexpectedly, or it may stop working entirely. The leak appears to be coming from small unwelded spots in the roof rail seams. Fixing this will likely require resealing or replacing the roof rail and replacing the failed liftgate control module.

Electrical System,structure →2 issues
Water leaks into your van through the roof panel on the left rear side, possibly through a bolt hole or seam, and pools around the Power Unit Liftgate Module. This moisture causes an electrical short that prevents your sliding doors and rear liftgate from opening, trapping you inside the vehicle. The wet electrical components also create a potential fire hazard. Fixing this requires sealing the roof leak and potentially replacing the damaged liftgate module and related electrical components.

Your tailgate won't open using the remote or manual handle, and a warning message appears on your dashboard. This prevents you from accessing the rear cargo area of your vehicle. The repair will likely involve diagnosing the tailgate locking mechanism and electrical system to identify whether the issue is mechanical, electrical, or both.

Fuel/propulsion System →1 issue
Your Odyssey started shuddering and misfiring, then stopped running completely and wouldn't restart. When it finally did start, it was running rough and barely moved. The diagnostic codes pointed to a fuel pump problem, and your mechanic confirmed the fuel pump needed replacement. Although Honda issued recalls for Odyssey fuel pumps, your vehicle was removed from the recall list in March 2024 and isn't covered. Fixing this will likely require replacing the fuel pump.
