Vehicle continues to go into limp mode causing us to be stranded on the side of the road. It is related to DEF injection system issues. It sounds like this is a known issue with the software. We purchased the vehicle in August and have been unable to use the truck since purchasing as it continues to leave us stranded. (Less than 3k is on the truck) GM has been unresponsive at best.
