My local Jeep dealership claims that the discoloration is normal and exists on all new Jeeps. This is the strangest thing I have ever seen. $50K product ... does not have a clean rear hatch window.
But why the ugliness ? What was going on in the heads of FCA design engineers? Couldn’t they have done a cleaner integration of the heater element into the glass like all normal vehicles ... or use a clean white / black substrate ?
Since a week after purchase 2 years ago (12/17 build) My JLUS had no working defroster until Jan. 2020 this year! I finally after 6 fixes including a new window and new wiring kit have a defroster that works, for now!
