IntelliBeam will sometimes allow me to activate the system but will turn itself off and not allow it to be reactivated until the power is cycled. Other times it will not activate at all. This is on a dark backroad with no traffic.

I washed my truck on a Saturday and as I was driving later that morning my tailgate opened while in transit. I did not notice this until I had stopped. After a little digging I found the 2019 tailgate electric switch is prone to this problem when it gets wet. There were no warning lamps for this problem.

Rear sliding window has a leak. While washing the vehicle or if it rains, water penetrates threw the window and into the inside headliner causing water stains and mold. Water also runs down the inside of the back window to the floor carpet, also creates water stains and mold. General Motors has a Bulletin 18-NA-383, Which does not fix the problem, but only puts a temporary patch. The permanent fix would be to replace the whole window.

Unknown. My truck has only about 46,000 miles . We experience heavy rains on the week of 4/8/2024 and I went to go load groceries in the back and saw water coming down the back window. I went straight to the dealer and spoke with Tom a manager at GMC. He took me to service and a mechanic came out and said this a common and expensive job. He said I may need anew window replacement. I left and did research on this problem. There seems to be EVERYONE who has a GMC or Chevy has this problem. Many people are experiencing rust, mold, etc. This is a MAJOR issue. All you hear about mold health isssues. NOT any issue that should be over look. Whenthere is water there IS mold. This issue probably has been going on longer but due to heavy rain and me going in the back I saw water. This is something that dealers need to fix.

Purchased a brand new from dealer 2019 GMC Sierra 1500 in July 2019. I noticed not long after that time that the back window leaked once in a while when it rained. I live in Phoenix Arizona, so rain is a rare occurance and it is in the back seat area of the truck where I do not sit back there or look back there very often checking for leaks. I mentioned it to the service advisor when I was trying to get a very long running issue with the tire pressure monitors that they would not properly fix. It took nearly 2 years for them to correct that issue, and by the time they fixed that issue, truck was out of warranty and they said they had no record of this problem and they could not fix. I am worried about the water causing mold or rust up under the head liner that would cause me and my family medical issues. Water, metal amd fabric head liners do not mix and there is a water stain on the roof liner that grows every time it rains. This is a medical issue and nobody should have to wonder what is growing above their head inside their vehicle while going to work. I see many online reports of a cracked window frame on these model year trucks, so it seems to be a widespread problem with either their vendor for these windows or the installation process at the factory.

The frame of the rear window cracked which allowed water to enter the cab. Water made its way onto the rear anchor strap of a car seat and saturated it which could have caused it to possibly not perform properly, which could have injured a child. Since the rear window can be opened electrically it is possible that a short could occur due to the water intrusion. GM has a service bulletin out about resealing the window but will not cover the repair or replacement of the window if it is outside the 36,000 mile warranty period. Obviously this is a manufacturer defect that has numerous occurrences or there would not be a bulletin created for it.

The rear window is leaking severely. It seem to be an ongoing issue with these trucks at the rear brake light spoiler. It’s a substantial amount of water and there is water damage and mold.

REAR VIEW CAMERA STARTING WORKING INTERMITTENTLY. TOOK VEHICLE TO DEALER TO REPAIR. DEALER UPDATED SOFTWARE AND THE PROBLEM PERSISTED THE SAME DAY. RANDOM SCREEN FOR JUST THE BACKUP CAMERA WILL BE EITHER BLACKED OUT OR BLUE STATING TO SERVICE REAR CAMERA SYSTEM. HAVE TAKEN MY VEHICLE BACK TO THE SAME DEALER THREE SEPARATE OCCASIONS TO RESOLVE THIS ISSUE TO NO AVAIL. NOW THAT MY WARRANTY IS EXPIRED THEY HAVE A FIX THAT WILL COST ME OUT OF POCKET. THEY ARE OFFERING COST ASSISTANCE BUT THE PROBLEM WAS NEVER RESOLVED IN THE FIRST PLACE.

A BLUE SCREEN WITH THE "SERVICE REAR VISION SYSTEM" APPEARED INTERMITTENTLY WHEN I PUT MY TRUCK IN REVERSE. AT FIRST IT WOULD GO AWAY ONCE THE TRUCK HAD RESTARTED. I HAD THE DEALER SERVICE DEPARTMENT CHECK IT OUT BUT THEY SAID THEY COULDN'T REPLICATE IT. THE CAMERA SYSTEM IS NOT ALWAYS IN A BLUE SCREEN REGARDLESS IF I SELECT CAMERA OPTIONS FROM THE INFOTAINMENT MENU OR IF WHEN PUTTING THE TRUCK IN REVERSE. THE DEALER IS CURRENTLY HAVING ISSUES WITH GM PROVIDING THE RIGHT "CALIBRATION" TO FIX THIS ISSUE. WHEN THE CAMERA WAS WORKING, A STRANGE ISSUE OCCURRED IN ADDITION TO BLUE SCREENS. THE RIGHT SIDE CAMERA TURNED OFF AND REMOVED VISIBILITY FROM THAT SIDE OF THE VEHICLE THROUGH THE INFOTAINMENT SCREEN. I FEEL THIS IS A HUGE SAFETY ISSUE SINCE MY VISIBILITY IS SEVERELY HINDERED WHEN REVERSING IN DARK OR DENSE CONDITIONS.

THIS MORNING WHEN I USED THE BACKUP CAMERA IT WAS PERFECTLY FINE. ONCE I GET TO WORK AND STARTED BACKING UP AT A SLIGHT TURN BC I WAS PARKING NEXT TO ANOTHER VEHICLE IT GAVE ME A BLUE SCREEN SAYING 'SERVICE REAR VISION SYSTEM'. IT ALSO DOES THIS WHILE STATIONARY. THIS IS A HIGHLY UNSAFE PROBLEM TO ME, BECAUSE IT DOESN'T ALLOW ME TO OPERATE THE VEHICLE SAFELY PUTTING ME AND OTHERS AT RISK.

GPS INFOTAINMENT SCREEN IS TO BRIGHT AT NIGHT AND THERE IS MINIMAL ADJUSTMENT THAT ALSO DIMS THE INSTRUMENT CLUSTER SO THAT YOU CAN'T SEE IT AND CONTROLS. AFTER DIMMING EVERYTHING TOGETHER INSTRUMENT CLUSTER AND THE GPS SCREEN AND PLACING THE VEHICLE INTO REVERSE THE SCREEN GOES INTO FULL BRIGHTNESS IF YOU PUT IT IN DRIVE THE SCREEN GOES TO THE FRONT CAMERA AND IS DIM LIKE IT WAS BEFORE PLACING IT IN REVERSE. THERE IS NO CONTRAST OR DIM OPTION FOR JUST THE INFOTAINMENT SCREEN. THE ONLY OPTION IS AUOT DAY NIGHT ALL ARE VERY BRIGHT AND DULL GRAY LOOKING LACKING CONTRAST. IT'S VERY DIFFICULT TO DRIVE AT NIGHT WITH THIS SCREEN BLINDING YOU NON STOP THE ONLY THING YOU CAN DO IS PLACE A RAG OVER IT. I CAN'T DRIVE THE TRUCK AT NIGHT IT IS VERY DISTRACTING TO ME AND I DON'T FEEL SAFE.
