Common Issues With Hummer Vehicles
Hummer vehicles often suffer from heavy wear on suspension and steering components due to their weight. Common issues include leaking intake manifolds, transmission overheating during towing, and four-wheel-drive actuator failures. Electrical system issues — specifically with the body control module and power window regulators — are common. On the H3, head gasket failure and cylinder head issues have been reported. Frame corrosion is a significant concern for vehicles in northern climates.
