  1. Did you ever get your parking sensors fixed? I've noticed mine did that for a while and then it stopped on it's own.. but I am worried I'll have to take it to the dealer if it happens again
  2. I bet this is what the HDs will eventually look like. With the column shift and full center console as well
  3. Did you ever figure out which harness you needed? I have the same issue. Harness I ordered has all the plugs needed except the one for the center console USB ports/SD reader
  4. You can but I believe you would have to buy new headlights as well. The WT and Custom use halogen lights which will not fit with the LT and up grill
  5. my '19 NEVER failed to auto lock. When I got my '21 it started to do it like 1 out of 10 times. I have a theory it may have something to do with the fact that they removed the rear door buttons. I noticed that usually when it fails to auto lock it is because I opened the rear door and closed it last. Usually if close a front door last it will auto lock. Also, if it fails to auto lock after closing the rear door, I can open a front door, close it, and then the truck auto locks.
  6. does the 10 speed shift quicker than the 8 speed? Or is the night and day difference people talk about just the fact that it doesn't have the rough shifting?
  7. How do you do this? So the Apple Maps directions will show up in the DIC screen between the speedo and tach?
  8. That worked!! Thanks y’all!! Sent from my iPhone using Tapatalk
  9. It’s located under the front passenger seat Sent from my iPhone using Tapatalk
  10. Does anyone know how to get this harness off?? Trying to replace it with one that has wireless charging Sent from my iPhone using Tapatalk
  11. I have a 2021 with an 8spd. I traded in a 2019 that also had the 8spd and it was a night and day difference. I would get all the usual 8spd complaints in the 19 but none of them in the 21. The only thing I can't comment on is if the 10spd shifts faster than the 8spd. I never drove a 10spd to compare it to
  12. It’s mainly for when you need to put stuff in the back. Happens all the time to me. Walking back from the grocery store and I need to open rear door to sit my kid in the car seat and groceries under the other seat and I have to walk up to the front door first and then push the button and walk back. Yeah it’s not a huge deal but it’s annoying especially after being used to having them on all 4 on my 2019. Sent from my iPhone using Tapatalk
  13. Wondering if we could just add the harness and button and have it be plug and play. I would think the vehicle should recognize them since some models still have them Sent from my iPhone using Tapatalk
  14. Yes, never had a hard shift so far wether I warmed it up or not. 3,000 miles and smooth as butter Sent from my iPhone using Tapatalk
  15. I just traded my ‘19 LT for a ‘21 RST and both have the 5.3 8speed. The new one however shifts way smoother. I used to get the shudder when switching from reverse to drive sometimes or the 1-2 downshift problems. Now I have absolutely no problems at all. I drove a trail boss before buying my RST and I honestly couldn’t tell much of a difference other than having 2 extra gears. My ‘19 was a late build too, it was manufactured about 5months after GM supposedly started putting the new fluid from the factory and the TSB or w/e should have been done way before I ever bought it but it still drove like crap compared to my new 8speed Sent from my iPhone using Tapatalk
