Rubbed The Wrong Way
Some owners of 2009-2011 Chevy Traverse vehicles (as well as 2008-2011 Buick Enclave, 2007-2011 GMC Acadia and 2007-2010 Saturn Outlook) may complain about an intermittent no-crank/no-start, liftgate inoperative and/or warning lights on.
Another concern may be that there is no communication on the low speed LAN with any combination of the following codes set: U0073, U0140, U0151, U0155, U0159, U0164, U0170, U0184, U0194, U0198, U0214 and U0249.
Inspect the wiring harness at the base of the left B pillar for chafing that may result from rubbing as the harness routes along the floor sheet metal.
There are two areas of concern: One is at the rear of the front door opening. The other is at the front of the rear door opening. If necessary, peel the tape from the area and look for any damaged wires. Repair as necessary.
