2017 CC Electrical Problem

[lonecountryboy]

So I have a 2017 CC 4x4 Z71 that has 4800 miles on it with a very strange electrical problem. I was hoping somebody else has had something similar happen so I have some info for the dealer when I take it in.

First problem: I noticed that when I was backing up and my rear parking sensor would go off to tell me that I was close to something it would beep for about a second and then the DIC would show that it had turned off.

Second problem: Right after the DIC would tell me that the parking sensor was turned off if I had the wheel turned at all the traction control and abs light would come on and the DIC would tell me to service the stabilitrak. It would then tell me there was a problem with the trailer brakes.

So I did a little experimenting and these conditions only occur when the parking sensor is active and you are turning either way. You don't have to be moving just the sensor beeping and the steering wheel is turned. If you turn the wheel back to center it clears. Pretty strange just wondering if anybody has any clue as to why all these systems are tied together? Or what could possibly be going on.

Thanks,

One more thing I noticed it seems to do it more when I am on a hill. If it is level and backing up it seems to only do it occasionally. Anybody have a service manual for one of these beasts? Or access to alldata? I would be interested to know what ties all these systems together.

So would the steering wheel sensor on the column cause this kind of problem? Cause now it will trigger the stabilitrak warning when I make a sharp turn going forward.
