There are 6 owner-reported engine complaints for the 2023 Honda Odysseyin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
I have a 2023 Honda Odyssey. The engine is making a knocking noise. The oil has just been changed with 5.7 quarts, following the factory specifications, but the knocking is still there. The timing belt tensioner has also been replaced, as well as the high-pressure fuel pump. However, the knocking noise is still present, especially at low speeds.
The contact owns a 2023 Honda Odyssey. The contact stated that while driving approximately 30 MPH, the vehicle started to lose motive power. The contact stated that the check engine and several other unknown warning lights were illuminated. There was an abnormal metallic grinding sound coming from the engine compartment before the vehicle stalled. The contact was unable to restart the vehicle. The contact stated that a tow truck was called, but the driver was unable to restart the vehicle to shift into neutral(N). A tow truck with a dolly was called, and the vehicle was towed to the dealer. The dealer diagnosed the vehicle and determined that the engine had failed and needed to be replaced. The contact wanted a second opinion and had the vehicle towed to another dealer, who also determined that the engine had failed and needed to be replaced. The vehicle was not yet repaired. The manufacturer was informed of the failure. The failure mileage was approximately 71,000.
An engine rod blew a hole in the engine block while traveling on the highway. This resulted in loss of engine power while others traveling at highway speeds around me. Additionally the vehicle was smoking heavily and smelled of burning . The vehicle only had 64000 miles with an adequate maintenance record.
The contact owns a 2023 Honda Odyssey. The contact stated while driving at an undisclosed speed, the engine seized. The contact stated that the failure occurred while she was on the entrance ramp entering the freeway. The contact stated that she repeatedly continued to depress the accelerator pedal, and after several attempts, the engine independently started. The vehicle was driven to the contact's intended destination. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 25,500.
While driving 35-40 mph, the car started acting strange, shaking and multiple alerts began appearing. No cars were around me and I was able to get the car over to the shoulder quickly. (Mileage 35,483. Owned car 20 months) Messages appearing: Electric Parking Brake Problem, Adaptive Cruise Control Problem, Road Departure Mitigation System Problem, Collision Mitigation System Problem, Hill Start Assist Problem, Emissions System Problem, Electric Parking Brake Problem, Electric Power Steering Problem, Vehicle Stability Assist Problem, CMBS Problem. I turned car off and on, multiple times, hoping it was a fluke, but car was shaking and messages kept appearing. I called Honda Roadside & car towed to dealership. Was told internal failure of oil pump was the problem. Techline reported Multiple vehicles with same codes and same motor have had the same problem. Replacement of spool valve, valve cover gasket & valve was the fix. This may be a future recall. Car drives fine now after being repaired!
Our AIS has not worked in most of the 3 weeks since we purchased it. We went on (joined) various Odyssey forums and apparently this is a known defect that Honda Corporation is denying (and can't fix). Som think it is a wrong battery in the vehicle issue or defective vehicle charger issue. Others have found a temporary workaround by opening the hood to reset it. Honda is ripping off customers for an AIS system that is defective. A class action is in order.
