Yes that is important. Probably less important for E7T but relevant for us here in Chicagoland, so we could avoid it !

As others have suggested have the grounds been checked?
It takes less than five minutes, you could do it yourself or just make sure they did. Sometimes you get lucky & it's the simplest things that need fixing.

Re: JGC 2015: 4WD, ABS, FCW, ACC, Parking sensors failure

Chrysler in Crystal Lake IL. As matter of fact we think that they did what they could. The problem was very tricky to find.
We talked to them. They told us that they are just following Chrysler's trouble shooting protocol. They hook up the trouble shooting device to the car and follow what it is suggesting. The first time the diagnostic device suggested that the ABS module was defective, they replaced it. The second time the diagnostic device was suggesting that the speed sensor in one of rear wheels was defective, and they replaced it.
We were telling them that since the problem manifested when the weather was humid or rainy, it could be due to a lose wiring or something like that. The third time they found the wiring harness on the passenger side was torn and they told us that they consistently could reproduce and fix the issue by moving the defective away from the frame.
They gave us the pictures that they took from the defective wiring. I am including those pictures to this post.

I am wondering that this kind of low quality wiring is common among the other car manufactures?

Maybe a rodent problem? Its hard to tell from the pics, but doesn't look like any chew marks on the loom.

They told us that it was not secured properly and was "dangling" and grinding to the frame. Probably driving the car under heavy rain made it worse. Tomorrow is the moment of truth, I will drive the car to the work. I will keep you updated if the warning lights come back again.
