The remote start, lock/unlocked the doors, horn, and vehicle location are working on my Jeep App. My understanding is these functions don't require a subscription for the GCL. I was under the impression there are additional connected services that are part of a six month free trial that aren't showing up in the Jeep App. My guess was it was somehow related to the odd messages on the mopar.com dashboard and the Jeep Connect webpages. There seems to be very little information about the GCL connected services.
Maybe check with your dealer to insure the services were activated when you took delivery. Mine mentioned more than once during delivery that he wanted to ensure everything was properly registered. We used the remote start, unlocked the doors, sounded the horn, and checked it’s location before I left.
We just bought our GCL about a week ago. Most of the time the remote start feature and location on th app don’t work and I can’t figure out why. Cell service is great where we are.
