I've had both issues since day one!! Saw the vents popped out when installing the tonneau cover. So upset as I brought this in many times for these issues. Just spent all morning cleaning up water and re installing these pricks with marine glue. So pissed! These vents go in from outside only, and require box to be moved back. But you can pull them back in from the inside and glue in place, add screws. It's a bit tricky to remove seat back, so check out youtube

It can be done if the dealer gets permission. A high end scan tool (non GM) can turn it off

Check for a popped out vent, under back window between box. Cant get it back in. Box needs removal to access just fixed it from inside remove back seat rest. Pull the vent back in easily I added marine glue and a screw to secure them. dried out seat back and carpet

Yes, but it's the vent that popped out!! Look at bottom of rear window, between box and below rear window. Chances are, a vent popped out! Replacing this is not easy, as the box must be unbolted and pulled back far enough to insert this @#$% thing. Thanks GM, for another useless feature that costs us time and money. Water pouring in FFS

Just wasted a day at the dealer. I left the truck for phone cutting out and rear cam bad display at night. They have replace the cam twice already, and updated the Radio software 4 times. I printed the latest TSB #25-NA-121, with update Y177. It states the dealer is to update the software if the customer has any issues with the Radio and dropped calls. TSB mentions IF this does not fix the issues, refer to SI diagnostics. After 2 hours, the service manager called and said "the tech cant find anything wrong, but the problem is your dash cam and trailer brake switch. She wanted to charge me for diagnosis as these added items were installed. The tech never looked for TSB's. I had to remind her of the TSB stating the new software must be installed first, then diag as need. I reminded her that a customer doesn't have to pay for anything they did not authorize. She then told the tech to update the software. He kicked out the truck without replacing the cam...probably pissed he wont get diag time. This is a reminder that knowledge of current TSB's is very important It's well worth the money to get ALLDATA DIY and have factory bullitins. No matter what make of vehicle, this knowledge of what is free can make a huge difference. Most car dealers are not forthcoming on what's free to the customer. It's easier and makes them more money to just charge you full pop, rather than making a warranty claim! Thing is, the TSB does not state aftermarket devices can cause issues. Many people with Radio issues have nothing added, but still have failures. Just beware that some dealer may try to blame you, and charge you, even though a fault is listed on TSB. You need to know what is warranty...only way is to have access to something like ALLDATA

almost $200 for just oil

So pissed. Just moving in my son and the truck acts up! Serious lack of power and all warning lights on dash. I checked TSB's and searched GM data. Found wire chafing common and can cause this code. Desperate, i crawled under hood and pulled that crappy harness at every spot they mentioned. Nada. Still shook. I know from years of repairing equipment that moving a harness that's chafing will cause immediate relief or symptom to get worse. Since no change, the next possibility was the #2 injector itself. It's under plenum, so that means parts, gaskets.... Off to dealer. They verified it's warranty so the GM loaner truck was covered. Got is fixed in 2 days, but i'm ready to dump this as it's too freaken early for major breakdowns. 40,000 kms Cant buy anything reliable these days Looking for an 80's GM with Quadrajet carb just to occasionally pull my trailer. So done with modern crap.

Just had the dealer install 0 dubya 40 instead of 0-20. It's killing 6.2 's and 0-40 is now installed as a fix for 6.2's I'm pulling at max load on my 5.3 and want best protection during summer months. Asked for 0 dubya 40 instead. Sure, good choice service manager said. Come time to pay bill, it's double the already high price to change oil. Over $300 Canadian. Can't wait for Amazon to open oil centres....lol So be prepared if you decide to upgrade to better protection!!

Yeah that ultra thin oil doesn't cut it at low RPM and load....exactly what i'm doing pulling a heavy trailer with my 5.3. Si, i'm puttin in the molasses too!

I had that happen soon after the dealer replaced the camera, and tailgate switch. They left the 2 10mm nuts loose! then water got in, took out the cam again. They put in another cam, nut this time i remover the tailgate cover and added dielectric silicone to all plugs and switch, cam. Then added black RTV silicone to exterior of handle housing...to stop water from getting in.

I've had all the latest updates...and still have dropped calls. It happens with or without cord, any iphone. Getting dangerous as you have to grab you're phone to continue the conversation. Might get me a ticket or cause collision!!

They installed my tailgate switch again. This time I asked them to leave off covers and bolts holding switch handle in place. With new switch, I removed it to inspect. Just what I thought, the tailgate switch is not weather proof. It’s not potted or properly sealed. Worse, the tailgate handle assembly has no gasket. The camera and light also let in water. So, water pours in the top of Handle assembly, through cam and light the switch also allows water to pour inside it. GM, you’re asking for trouble here. Designed to fail. Possible lawsuit from tail gate opening and activating my trailer Jack. It actually lifted my back end at a light. The tailgate hits the electric switch perfectly. as a construction equipment tech that fixes outdoor machines in cold wet weather, I see the flaw here in your design I added dielectric silicone to the switch as any moisture will short out the card. I siliconed the handle, switch exterior and filled in holes at camera ( the other Constant failure from water) now, the whole thing is sealed from elements like its supposed to be!! GM… add seals to these switches and cameras. Use outdoor potted switches of at least dielectric! You’re spending thousands on cameras and tailgate switches just because of improper sealant.
