What owners wrote
A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.
Driving home I began to smell and electrical burning smell. It began very quickly and came and went for about 2 miles. I pulled over and looked and could not see smoke or fire so I continued home. I drove the remaining 4 miles to my home and immediately got my husband to check as the cab had filled with the smell of an electrical fire. He located the area the smell was strongest and then watched as smoke came out.
Heater fan blower motor started working intermittently while car in motion, then smell of burning electrical. Wiring harness to heater under the glovebox was burning hot to the touch and melted all the wires. Plastic wire harness component completely destroyed and almost caught fire.
Tl* the contact owns a 2005 hummer h2. The contact stated that the driver side heating element turned on without warning and failed to turn off. The vehicle was taken to dealer three times, where it was diagnosed that the driver seat module needed to be reprogrammed. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 48,000.
Check engine light keeps coming on and light blinks than stays on until I take it in for service. The shop can't figure out why it is doing this had it shop about 7-8 times for service. Also code states can cause a possible fire
