Honda Odyssey Common Problems

ELECTRICAL SYSTEM

Owners of the 2018 Honda Odyssey frequently report issues with the electrical system, particularly involving water leaks affecting the tailgate control module, leading to repeated failures and malfunctions of the tailgate. Complaints often describe the infotainment and media touch screen displays going blank, which affects the backup camera and climate controls, sometimes occurring more frequently when the vehicle's AC is used. Additionally, multiple reports highlight problems with the vehicle's cameras, such as the monocular camera overheating, causing numerous warning lights to illuminate and disabling various safety features like lane assist and cruise control. These issues are typically reported at mileage around 50,000 to 60,000 miles, and while no crashes are directly mentioned, the loss of critical safety systems and the potential for the tailgate to open unintentionally pose safety risks. This information is crucial for potential buyers considering a used 2018 Honda Odyssey, as these electrical issues could impact both convenience and safety.

ELECTRICAL SYSTEM

Owners report several electrical system issues with the 2020 Honda Odyssey, primarily involving failures in safety-related features and components. Complaints frequently mention malfunctions in the Honda Sensing safety systems, including adaptive cruise control, lane keep assist, and collision mitigation, often linked to a failing forward recognition camera or multipurpose camera unit. Symptoms such as warning lights, system disablement, and infotainment system failures are common, with issues appearing around 30,000 to 130,000 miles. Additionally, problems with the sliding doors and rear hatch not opening, attributed to water ingress or electrical faults, pose significant safety risks, especially in emergencies. These patterns suggest potential safety implications, as multiple owners describe instances where these failures could lead to dangerous driving conditions.

POWER TRAIN

Owners report several recurring issues with the 2019 Honda Odyssey's powertrain, primarily involving transmission problems. Complaints frequently mention symptoms such as transmission slipping, hesitation during acceleration, harsh or erratic shifting, and sudden loss of propulsion. These issues often occur at mileage as low as 66,000 and up to 133,000 miles. Safety implications are significant, with multiple reports of vehicles stalling or unexpectedly shifting into neutral, creating unsafe conditions particularly during merging or in traffic. Used car buyers should be aware of these potential transmission issues and consider the mileage when evaluating a purchase.

ENGINE

Owners report that the 2018 Honda Odyssey frequently experiences engine failures primarily due to connecting rod bearing issues, often necessitating full engine replacements. Complaints frequently mention symptoms such as knocking noises, engine stalling, and the presence of metal shavings in the oil, with failures occurring typically between 66,000 and 167,000 miles. Many owners indicate that these failures occur without prior warning lights or messages, posing potential safety risks such as sudden loss of power or stalling in traffic. Used car buyers should be aware of these recurring issues, especially considering that some vehicles with these symptoms fall outside the scope of existing recalls.

FORWARD COLLISION AVOIDANCE

Owners report frequent failures of the front monocular camera in the 2019 Honda Odyssey, leading to the inoperability of several advanced driver-assistance systems such as Collision Mitigation, Lane Keeping Assist, and Adaptive Cruise Control. Typical symptoms include multiple warning lights and error messages on the dashboard, often appearing suddenly when starting the vehicle. These issues are commonly noted around 40,000 to 80,000 miles, with some reports indicating failures under varying weather conditions. The loss of these safety features presents potential safety implications, especially as drivers may rely on them for crash avoidance. Repair costs are mentioned as significant, often exceeding $1,500, which may be a consideration for used car buyers.

FORWARD COLLISION AVOIDANCE

Owners report that the 2018 Honda Odyssey frequently experiences failures in its forward collision avoidance systems, primarily due to issues with the front-facing monocular camera. Typical symptoms include multiple dashboard warnings for adaptive cruise control, lane keeping assist, collision mitigation, and other safety features, often occurring without prior indication. Complaints suggest these issues can emerge at varying mileages, including some vehicles with low mileage. Notably, two complaints involve crashes, highlighting potential safety implications when these systems fail. Potential buyers should be aware that resolving these issues may involve significant repair costs, as reported by some owners.
