I have a 2017 Charger RT 5.7 that’s giving me a new issue. The new issue is not wanting to start. When I try to start it, it gives a slow crank and just stops with a click. When I try to start it again it just clicks once and it doesn’t start. If it sits for a while I may end up starting like it did this morning but it usually doesn’t. I’ve replaced the battery and the alternator is running at nominal operation. I’ve looked to see if anyone else is having the same issue and seen that some 5.7 owners are having difficulties with the starter. Can anyone shine some light on the situation? Keep in mind I still have error code P121b registering, could that be a cause of this?
