Summary Verdict
The 2003 Honda Odyssey is a generally reliable vehicle, particularly its powertrain. However, owners should be aware of potential issues with the timing belt, VVT solenoids, and the automatic transmission, especially the torque converter. Suspension components like control arm bushings and struts can also wear over time. Electrical issues, particularly those related to the Body Control Module and alternator, are also documented. Proactive maintenance, especially timely timing belt replacement and regular transmission fluid services, can significantly mitigate these risks and ensure a longer service life for the vehicle.
