I bought this vehicle used form Carmax, <12000 miles. Drove about 12 miles, when while parking I noticed the car stopped and asked to start engine and engage gear again. Didn't think much of it. Then started driving again and the check engine light turned on.

Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Stellantis warranty extension on file lists the ones Stellantis has filed.
Which vehicles does 1800424 cover?
