  1. 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.
  2. Hello all, new to the forums. For the last week or so, I've had an issue where my lane keep assist / forward collision alerts and braking does not work. I've had the truck for 3 months, 7k miles on it. Got it washed and looking all nice, then 2 days later the lane keep assist stopped working. When I press the button on the center stack, the DIC reads "Lane Keep Assist System Unavailable". I noticed that the icon on the dash and the HUD are both missing now, acting like it has never been there. I've drove through rain since (thinking maybe it was too thick of a car wash wax), but still nothing. I haven't had time to take it in to the dealer since it has been the holidays. Has anyone else experienced this or have any ideas on how to get it back working? I drive between Missouri and Indiana a lot, so I have been missing this feature. Thanks for any help!
  3. I have a 2017 GMC Denali pickup and it has the Lane Keep Assist on it and I really like that. The problem is that it won’t assist until the tires are on the center line or slightly over the center line. The assist works much better when the tires are close to the right edge and will turn the steering wheel when the tires are around one or two feet from the line. I would like it to do the same distance from the center line. Is there a way to adjust the camera?
  4. I am receiving a "Service Front Camera" on the DIC upon starting my truck. I also can not activate the lane keep assist switch. I assume this could be from a dirty camera lens; it has been misting/raining today. Any ideas of how to clean the lens?
  5. Just purchased our 2018 Yukon Xl with Lane Keep Assist. The lane keep assist will not turn the wheel until I am approx.. 18 inches over the lane. It will then move the steering wheel to get me back in. if I don’t touch the wheel it will go all the way over the opposite side lane approx. 18 inches and when the vehicle crosses the lane line on the opposite side it advises to take control of the vehicle and vibrates my seat on the side I’m over that line. I was informed by my GMC dealer this is normal and they took the vehicle for 2 20 mile test drives. I asked them to put in writing that 18 inches over the line is correct according to GM engineer that they had on the phone. Every ounce of my body is telling me this is not how it was designed. On a back rode in New England you are lucky if a pole or tree is off the road by 18 inches. Which means before Yukon even senses I’m over the line I would have hit something. I had a 2015 Yukon with Lane Departure Warning and the thing would go off if I was within 6 inches of the lane on either side. Someone Help!!!!
