I have a 2017 Grand Cherokee that is 4 weeks old. Started it up a couple weeks ago, wouldn't go into gear. Shifter seemed locked up. Display said "service shifter". I turned it on and off several times, until it finally went into reverse.
This week it happened again, only this time the check engine light came on too. Again....turned on and off, opened doors, checked gas door etc. Finally it would shift, but check engine light stayed on. Later went out.
Called the dealership, they took my Jeep Thursday. Talked to them Friday, and they said they checked the codes etc....they checked the pins and connectors, and said they really don't know what is wrong. Now they say they ordered a connector for it and hope this would fix it.
Anyone else experienced this issue. I have a feeling I'm going to get it back and it will do it again........
