Multiple issues 2018 Chrysler Pacifica, 3.6L V6
We keep getting the "Service Shifter" message and we've taken it to 2 different dealerships for work under the extended warranty. The first dealership said that the issue was caused by an aftermarket wiring harness for a GPS tracker (presumably for repossession purposes). They removed the wiring harness, but I got the same message when I picked it up. My wife took it to another dealership in another town, they replaced the shifter knob and said that the other messages (Adaptive Cruise Control off, Service Electronic Stability Control, FCW Unavailable Service Required, ACC/FCW Limited Functionality, Start/Stop Not Ready) were all due to an issue with a faulty Starlink module behind the glove compartment. They said not to worry about that, there is supposed to be a recall on the module soon. The vehicle is drivable, but the acceleration tends to lag badly when the error messages start popping up. I have tested the voltage on both batteries and they both are at 12.6V, the alternator is outputting 13.8-14V.
