One problem related to wiring has been reported for the 2017 Chevrolet Volt. The most recently reported issues are listed below.
When I shift my car into park and push the power button to turn off, a message displays on the gauge cluster to "shift to park" and the car does not let me turn it off. This issue has happened multiple times and through googling I have seen many other gen 2 Volt owners having the same issue. When I mentioned it to my service writer at the dealership, they knew the issue was related to the shift linkage/wiring harness but refuse to fix it despite being a known common issue.
