Same issues in my brand new 2018 compass. Rear window rolls up and down by its self, Engine running screen comes on, door open dash alert comes on, interior lights turn and and off by them selves, etc. Been to the dealer 3-4 times already and every time, the issue stops for a few weeks and then comes back, sometimes even worse than before. They replaced the master window switch and the OBD, but the issues keep coming back. Was told this morning b the dealership service dept. that Chrysler/Jeep tries sending an update out to all vehicles and that it caused many electrical problems for many owners. I find it strange that this would do that to mine since I have had these issues since the start. Not sure what to do as I really like the car, but paying for a brand new broken vehicle that I cannot use is ridiculous. I paid a lot for this car and am very disappointed.
Anyone have any luck with similar issues?
Welcome to the 2017/2018 Jeep Compass electrical issues club!!!
These problems definitely all sound related and they definitely seem to be the same “communication issues” my Jeep was having. The terminal chip replacement has so far worked for the major issues, but it still has some minor electrical problems that are more so annoying than anything else (hvac acts temperamental, turn signals no longer make the clicking noise).
The major issues mine had were found to be related to bad terminal chips. These are computer chips about the size of a thumb nail with tiny pins that make contact and facilitate communication between the various systems of the vehicle. Mine had some bad terminals. When it was cold, the microscopic amount of shrinking would keep certain pins from making contact and those systems would go haywire. When the vehicle would warm up, the chip expands and the pins make contact again bringing the systems back online. When everything is warmed up and back online the vehicle tests fine, so the service tech can’t see anything is wrong. There should be a STAR case out there on mine that other dealerships can see. The problem is accessing these terminals involved tearing apart the vehicle and is very labor intensive, so nobody wants to do this right away.
Between my wife and I, we have had 7 Jeeps going back to a 1997 XJ Cherokee. What do they say? The definition of insanity is doing the same thing over and over again and expecting a different result?
Oh and I’m still getting about 14 mpg ... I’m a conservative driver who normally gets well above the epa mileage on the sticker.
All I can say is good luck to you and don’t let them try saying resetting the system or a software update is the fix. Mine had to go through a complete rewire of the wiring harness and replacement of 3 of 7 terminals to get to this point.
