NHTSA complaint: 2008 CHEVROLET TAHOE — ELECTRICAL SYSTEM
The battery energy control module GM Part # 84442220 located inside the HV battery assembly caught fire. The harness that was most affected was the battery cell voltage sense wires. The way the battery voltage sense circuit is manufactured seems dangerous as there is no fusible link between the battery cell and the module. If a short circuit occurs the full current of the cell will be induced on a very thin gauge wire going to the module which will result in a fire.
