Consumer Description

Engine wiring harness failure on my 2017 Silverado 2500HD LT 6.6. This time it is the cylinder 7 connector which is a very common complaint by Chevy owners. The wiring harness was installed with wires that were to short for the rear cylinders causing them to fail prematurely. This connector is snapped into position forcing the wires to bend at a tight 90 degree angle. Chevy is trying to force owners to replace the entire wiring harness instead of replacing just the defective connectors (GM 19368140, ACD PT3739). This failure causes the engine to idle and operate so rough that it engages STABILITRAC and forces reduced power mode.
