I have a 2017 Volt LT. 1 month old. My car started stalling out and I got a check engine light. These are the error codes P0106-00 MAP SENSOR and P0404-00 EGR. Per On-Star the issues were related to the transmission and emission systems and required immediate attention i.e., car had to be towed. It took the dealer a week to resolve. Seems to be fixed, but I'm driving it on gas only for now to give it an extended road test. I only drove the car on gas for about 100 miles over the month I owned the car. Wanted to see if others have had similar issues.
