2020 Gmc Sierra 1500 Wipers & Visibility Problems

The rear back glass is leaking water excessively in to the inside of the vehicle when it rains or gets washed. The vehicle is available at any time for inspection. The amount of condensation that accumulates on all the interior windows makes it impossible to see out of the vehicle. The defrost can not handle the amount of moisture build up. The Dealer knows about this condition and it has been verified by a window company. The manufacture knows and understands there is a problem and has put out a Technical Service Bulletin ( TSB 18‑NA‑383 ) for this issue but will not cover the repairs. GM knows that every single vehicle with this window designs from 2019-20121 will leak just outside the 3 year 36k mile warranty coverage. The cost of repair is approximately $2k. Dealer will not cover repair.

The contact owns a 2020 GMC Sierra 1500. The contact stated while detailing the rear interior of the vehicle, the contact discovered water surrounding the rear windshield casing and the water was leaking into the rear seating. Additionally, the rear carpet was soiled with water. The contact used towels while attempting to soak up the water. The vehicle was taken to the dealer where it was diagnosed that the failure was due to the failed rear windshield glass fasteners. The contact was informed that the failure had damaged the rear carpet, padding, and the rear seat. In addition, the contact was informed that the carpet and padding needed to be replaced due to mold build up. The contact was informed that the vehicle was out of warranty coverage. The vehicle was not repaired. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 31,000.

The rear window on this vehicle is leaking water and has been for some time. It has become quite bad and is causing an odor and discoloration in the carpet. I could not find the cause of the problem until recently with the plastic cracking more. The vehicle has 41,000 miles and the dealer stated that is out of warranty and all repairs would be a cost to me. I researched this and have found it is a common fault this this vehicle.

My back window leaks and gm has said that the warranty is over by years not miles it is not covered

My rear window leaks there is a bulletin on it Call GM says it is not responsible for the repair because it is over on the years but not the mileage it’s clear they know about the problem it’s in many pickups that gm manufacture here is the bulletin file:///var/mobile/Library/SMS/Attachments/97/07/3010617D-BBB0-4FB8-859B-4BA5E2BE3F3A/Ed%20blakeslees%20truck.png

WHILE DRIVING ON A STATE HIGHWAY, I HEARD A "POP" SOUND, I SAW NOTHING CONTACT THE VEHICLE, BUT I THEN NOTICED THE WINDSHIELD WAS CRACKED. THE WINDSHIELD CRACKED FOR NO APPARENT REASON..

WIPERS FROZE TO WINDSHIELD WHILE DRIVING WITH DEFROSTER ON MAX. DESIGN OF THE WINDSHIELD AND DASH MEANS WIPERS SIT LOWER THAN WHERE THE DASH AND WINDSHIELD MEET, AND NO WARM AIR FROM THE DEFROSTER CAN GET TO THE WINDSHIELD WHERE THE WIPERS SIT. THERE IS NO IN WINDOW DEFROSTER (LIKE REAR WINDOW) WHICH CAN HELP. MAJOR SAFETY ISSUE IN SNOW/ICE CONDITIONS.

BACK UP CAMERA IS AWFUL AT NIGHT. THIS IS A SAFETY ISSUE BECAUSE YOU CANNOT SEE ANYTHING WHEN BACKING UP. MY TRUCK HAS 323 MILES ON IT AND I WENT TO DEALERSHIP THEY SAID I WOULD HAVE TO LIVE WITH IT. THAT IS NOT ACCEPTABLE TO HAVE A SAFETY FEATURE THAT IS FAULTY.
