What to check on a used 2007 Hummer H3
- Electrical: test every light, window, lock, the infotainment screen and the charging system; scan for stored fault codes.
- Engine: cold-start it yourself, listen for ticking or knocking, check for oil leaks and oil consumption, and ask for oil-change records.
- Visibility: test the wipers at every speed, washers, defrosters and the climate system (fogging is a common complaint).
- Body: look under the car for rust or damaged subframe and rocker areas, and check panel gaps for signs of repair.
- Recalls: confirm each of the 2 campaigns above was completed on this VIN; open recalls are repaired free at a dealer.
- History: run the VIN for salvage, theft and odometer records, and have an independent mechanic inspect the car before you pay.
