2019 GMC Sierra X31

[ajwasco]

Purchased new in May of 2019 in Alabama so, after a first or second freeze here with very light snow. Drove to work truck parked in sun all day, temps rose quickly outside. End of work day get in truck and the entire lower half of the windshield was soaking wet with condensation.
It appeared to have drip marks from the upper center cover on inside of window.

After a strong rain Monday night the inside windshield covered in condensation that had to be wiped down the defrosters would not clear it.

Also when the rear window is wet, not fogged up and i turn on the rear defroster it sounds like bacon frying from the passenger side lower corner.

Can't find anything on forums but did find recalls on trucks manufactured in Canada with no fix other than disable or don't use. This truck was made in USA by VIN.
Dealers is avoiding because it doesn't happen in car wash or when they hose it down.
Any help appreciated. Thx

Update took in yesterday to dealer. They stated that the rear window track is a known issue and apparently has been leaking since it was born. water finds its way down the driver and passenger side door sills and carpet and padding wet. Guess the truck is lower in front some and water caused condensation after truck sits all day........we'll see.
ON another note there were four recalls to be worked one causes a front camera calibration. On way home noticed lane assist light would not go out and lane assist was inop. Not sure if the hi beams will shut off either with oncoming traffic will check in morning. Back to dealer who is over an hour away
