  1. So earlier this week I stopped at our local tire shop and took the shop foreman for a drive. Couldn’t wait for my apt. Set for today. He said it is the tires. So I ordered in a set of Falken wildpeak ht02’s in and they got installed yesterday. Boy what a difference. Took them for a 40 mile run. No noise and they averaged 26.5 mpg. This is 2 plus mpg more than the duratracs did for me in 600 miles. These I felt were the best value as I priced Bridgestone duelers and Michelin’s which came in a lot higher. I want to thank all of you for your input.
  2. 41psi per tire. Tried 38 and 44. All pressure checked and filled when cold. Door label states 41psi cold.
  3. Live in Iowa and just traded my 2019 at4 due to this problem. Last 2 years when it gets cold and til spring my truck coming out of my driveway and leaving work would shift hard between 1st and second everyday when temp below 40 degrees. You could let the truck cycle through 2 starts and it would still do it. The fluid needed to build pressure while moving. The truck routinely would stutter went coming to a stop as it was trying to find the right gear. Had to dealer 3 different times and called gmc and they would do nothing. They told me and printed a service bulletin and gave me a copy that said it was normal. I tried living with it cause the truck was awesome other than the cold shift. I was so mad 3 weeks ago when gmc rep called and said they talked to the dealer and the dealer said it was normal operation and was fixed. I went off. Said your telling me it is normal for a 60,000$ truck is supposed to shift hard and damn near throw you through the windshield when it grabs and you call that normal. She was quite and started apologizing. That pissed me off. It is not like the days of actually talking to a factory rep but now we talk to an answering service and doesn’t escalate higher. I kept to gmc and bought another At4 with a 10 speed an couldn’t be happier with the tranny I got.
  4. Have a appointment set up this Friday and will update. Why only between 25 to 35 mph do these tires rumble really loud. Why not at higher speeds. That is the most confusing thing to me. Do they crown and flatten out? It is just bizarre to me.
  5. Just traded my 19 at4 w/17,000 miles and they squeaked forward, reverse and while stopping.
  6. Thanks for the heads up info. After I get it through the dealer and/or tire shop I will let you know the outcome. Just a bad pet peeve of mine. Expensive truck with loud road noise. ‘thanks again for your input.
  7. I just traded my ‘19 at4 with 20” tires for a 2021 at4 diesel with 18” tires with Goodyear dura tracs on it. During the test drive I noticed what I thought was some tire noise due to the aggressive tread but didn’t think much about it at the time. Well we struck a deal and headed home 2 hours away. The noise was more pronounced on the way home and in town now and settles in around 30 mph and seems to drive out of it as you increase speed. But when you slow back down it hangs in there til you stop. Now the hard part is describing it but sounds like a whirling noise or uneven tread slapping the road and coming from the tires. Or could it be bearings? Truck has 350 miles on it. I have been researching the dura tracks and people say they are pretty quite. The noise is very noticeable in the cab. I will be making an appointment to see what service says but was wondering if anyone else has come across this problem.
  8. Have to say I couldn’t feel or notice a difference til I had my first oil change then it changed. At low speeds in town, 20 to 30 mph, I notice the shutter in my seat and steering wheel. I know the feeling cause my wife’s ‘19 Yukon Denali has the same terrible feeling while cruising at highway speeds. Any insight on a problem that developed during the oil change and fix or do I have to deal with it? 2019 GMC Crew 4x4 AT4 with 5.3 and 8speed transmission. 9000 miles.
  9. This is our second Denali that has paint chipping off the plastic bumper on the top edge on both sides where it meets the fender. There must be a fair amount of flex going on that causes this. Has anyone dealt with this issue yet?
  10. After 2 weeks and a new radio, a receiver and a hmi module the Yukon is finally fixed. The hmi was the final part installed that fixed the problem. Like I mentioned in an earlier post we have to go back and have them install a bezel that they scratched during removal. They said due to the GM strike that part will take awhile to get. Thanks everyone for your input and the wealth of knowledge here on this website!
  11. Tried the fuse trick with no luck. Just noticed today the hdmi ports below the radio do not work either. Starting to wonder if these are related to the radio black screen problem. Also noticed after startup radio works with black screen but after a minute it cuts out for a second here and there for a couple more minutes then hoed dead. Ground? Back to the dealer on Tuesday.
  12. Well 5 days at the dealer, still have black screen and radio not working. To top it off I noticed the bezel around the a/c controls and the one above it are scratched on the sides where they pryed to get the trim off. Frustrating. We will see what next week brings now.
  13. Passed the info onto the dealer this morning. Stopped by this afternoon and they said they ordered a new radio and receiver. They believe this is the culprit. We will see tomorrow. Thanks for your input.
  14. Didn’t think my first post would be a problem with my Yukon but here I go. This weekend the wife started her Yukon up and screen on radio was black. She had sound but only stays on for 3 mins after starting and then dead silence. During the 3 minutes she could only use the steering wheel radio controls to adjust the radio. Turn the beast off and start again the radio plays for 3 minutes and off it goes. The whole time though when she backs up the camera displays on the screen and in drive again goes black and still no radio. The dealer got it in first thing this morning but is perplexed as what it is as they worked on it for 5 hrs today with no results. Has anyone had this problem and any ideas what it might be?
