I have a 2018 SEL Premium with 4 motion with about 95k Mike’s on it. Sometimes when coming to a stop at a red light or when maneuvering in a parking lot at slow speed, the engine RPMs get dragged down to where engine almost stalls or does stall. It feels like torque converter is not disengaging. This has been happening for quite some time but frequently in the last 10k miles. Any idea if this is a common issue? What could be the cause?
