More than two weeks ago, my 2017 Chevrolet Volt LT showed BECM codes. The local dealership service center said they would order the parts for a complete replacement. The work and parts are covered under warranty as this has been a common issue. The BECM and coolant arrived within a few days, but the remaining parts are back ordered! After two weeks of waiting GM has failed to send the parts and I and my family are in need of our vehicle for both work and safety reasons. The part number for the parts that still need to be sent is: 11517042. The warranty coverage number from Chevrolet’s bulletin in regards to this failure is: N232432680.
