Electrical System
331 complaints (31% of all Hummer complaints reviewed). Electrical problems are made worse by desert heat, which ages batteries, cables and connectors. We test the battery, starter and charging system and trace faults to the actual part.
Engine
141 complaints (13% of all Hummer complaints reviewed). Engine and cooling complaints are best caught early in Phoenix, where heat pushes cooling systems and engine oil to their limits. We diagnose warning lights and check coolant, hoses and oil condition.
Visibility
117 complaints (11% of all Hummer complaints reviewed). Lights, wipers and visibility items are quick to fix and are on every rideshare inspection checklist. We check them as part of our inspection prep.
