Summary Verdict

The 2004 Honda Odyssey is a capable minivan, but potential buyers and owners should be aware of common issues. The VCM system and timing belt are significant concerns for the engine, while transmission problems, particularly torque converter issues and overall failure, can be costly. Suspension components like control arm bushings and struts are also prone to wear. Electrical issues such as failing alternators and power window regulators are not uncommon. Exterior rust can be a problem in certain climates. Addressing these potential issues proactively through regular maintenance and inspections can help mitigate repair costs and ensure the longevity of the vehicle.
