Adaptive cruise, lane keep assist, and auto high beams not working on 2021 Silverado High country..

Water pump recently went out had to get it towed to dealer they replaced it but when I got the car back these don’t work.

Third time this truck has been in the shop don’t really feel like taking it back. First time 4WD was broken.. second time my lifters collapsed. 
Any suggestions on fixing these tech features or should I just take back to dealer.

For sure annoying. I feel your pain. GM service departments seriously lack competency all too often.

 

If you just don’t want to deal with it you could look around yourself fit a connector unplugged. I’d check around the front bumper, grill, front of engine bay. 

 

Do all of your cameras work?

Assuming it didn't gt unhooked for some reason, adaptive cruise temporarily unavailable can be dirty windshield (in front of where mirror mounts) as that is where the camera it uses is located.  I've had it happen after freezing rain when I didn't get all the ice off that spot on the windhield.

 

Can also happen driving into a 'low in the sky' sun, which is blinding the camera. 

After road curves or sun sets or clouds block sun the problem shoild clear.

 

 

Lane keep and intellibeam also use cameras.

Not sure if they use info from the same one.

This happened to my truck in nov. Of last year. They had to order my truck a new windshield camera which controls all of those options. Took them 2 months to be able to get one in because of parts shortage. They actually had to acquire one from another dealer.. But this sounds like the same problem GL

      Like new, Pulsar LT for sale, bought direct from manufacturer. Box is included as well, just can't upload a pic of it for some reason.
       
      Had this installed on my 2021 Chevrolet Silverado, took this off when I traded it in. Works great, ~10 months of ownership.
       
      Looking for $400, shipping included, within USA. Venmo/Paypal/Zelle preferred.

      What suggestions or advice is available for buying a GMC | Chevy truck? What should I watch out for -- the GOOD and BAD? 
       
      I want to come back to the GMC | Chevy family. For over 20 years, we owned a 98 GMC Suburban, putting over 230k miles on it myself, and I LOVED that truck. Other than typical wear and tear -- I never had any problems or issues with my Suburban.
       
      I am looking at 2016-2022 -- GMC | Chevy 1500 | 2500 series, all trims (4x4), except the base models. My budget is around $35k plus'ish; yes, I understand my budget limits what I can get. I am a USAF retired veteran living off a fixed income.
       
      Yes, we tow hitch pull RVs and various trailers, but not as often as before. What are the GOOD, BAD, and UGLY these days on the GMC | Chevy trucks? Is the additional price for either diesel and/or 2500 worth it?
       
      SHORT STORY: so, a few years ago, I bought a 2015 Ram 1500 4x4 EcoDiesel 6cyl w/turbo Lonestar -- well, I have been disappointed with Chrysler | Fiat (FCA). They lied about the EcoDiesel, and after forced recall ECM updates, they sucked all performance and mpg from the truck. Buying a newish GMC | Chevy, I do not want to fall into what happened with my 2015 Ram. When I had my suburban, I never had so many recalls, been lied to, and never had poor performance.
       
      Thanks for any suggestions that you will provide -- Gary (ExFalconFxr)

      I recently purchased a 2013 Silverado 1500 LTZ 5.3 crew cab and am averaging 13.6mpg. I understand it's a truck, but I figured it wouldnt be that terrible. I use cruise control and coast as much as possible, but still have the poor mileage. It has 117,000 miles on it. I have 33x12R20LT Trac Grip M/T Thunderer tires and XD series wheels. I feel like I should be getting better gas mileage than this. Suggestions?

      If anyone has any experience with my situation please feel free to comment with any tips or your own experiences. I have 3" front 2" rear level on my 2018 silverado. I left everything else stock in the suspension and after about 30k miles I now have completely blown my CV joints. I will be replacing the CV axels, UCA's (recommendations?), and installing a differential drop kit this weekend. Hopefully this helps relieve the angles of the ball joints and CV axel. I've never done a diff drop before so wish me luck. Hopefully it's not too terrible of an install.

      Got my full console from Ebay used in like new condition. I did alot of research to figure out how to wire it so all the functions would work. I.e. wireless phone charger and  usb/ cigarette liter ports for the rear passenger.
      I have a currently have a 22 2.7l Custom that doesn't have the required connection under the front passenger seat. After hours of looking at schematics and testing wires, I managed to hard wire my center console to the fuse box on the passenger side.
       
      Wire on the CC harness to Fuse box
      Both Red/white to F5 (Battery positive)
      Violet to F20 (Accessory on)
      Violet/yellow to F23 (Accessory on)
      BOTH Black to Ground below the Fuse box.
       
       
      The only section I wasn't able to get working yet is the USB in the middle of the console (the one with the map SD card). This one I believe needs to be connected to the radio that has the built in navigation. (once I get one I'll update this post.
