2021 1500 Denali. Went to work this morning and found that I cannot change radio stations. Seems to be locked on one AM station. Tried direct tune and presets. Don't have too much time to mess around since warranty almost over, 35,700 miles. Just curious if this has happened to anyone else.
Just running pump fuel. I wasn't aware that I needed an anti-gel additive. Live and learn. after doing some reading, I will probably put in an additive on every tank. I suppose it couldn't hurt.
it was around 9 - 15 for over 24hrs. I did not have any anti-gel additive (but I do now). Hopefully that is all it was. since it is still running great
Got my truck back and running great. Dealer said it was diesel gelling because it was too cold. They claim to have done nothing except kept it in the heated shop overnight. Not sure I am sold on the story
2021 Denali 4WD, 32k miles. It seems okay (at least around the block) if I keep it under 20mph. As soon as I accelerate, I get the warning and it dies. It does start every time but the dealer is too far away and too much traffic to chance driving, so I had it towed. Internet searches...
When my wife got a 2020 Toyota Highlander I connected my Samsung phone and email/sms messages just started showing up. I could 'speak' to the nav system and it worked flawlessly. The next year I bought my 2021 GMC Denali 1500. What a disappointment in this area. Now I have to pull over and...
2021 4wd Sierra 1500 Denali. My daily commute has been averaging close to 25mpg. I now have around 16k miles and it seems like the last several fillups keep increasing. I am now averaging a little over 27mpg. I drive around 250mi/week. Definitely not complaining, just curious if this is...
2021 Denali 1500 with the 3.0L diesel. Owner's manual isn't really clear. Manual states all 4 wheels are powered. Is AWD mode just enhanced traction control? If so, if you hit a sheet of ice or mud, does it actually switch to 4WD? I don't really have a way to play around and see what really...
As a side note, the dealer gave me a new pickup with the 5.3L gasser, only 380 miles. Seemed so sluggish and it wasn't even 4WD. I averaged 17mpg on my normal commute vs 26mpg on my truck. Soooo glad I got this little diesel
I just experienced the same warning light @ 10k miles. Took it to the dealer and they found the exhaust back pressure valve was leaking. Hope this isn't an ongoing problem.
I tend to agree with most. My normal commute is 50 miles/day, mostly on tollways in North Dallas area. To me, Sport mode seems like steering and especially braking is much better for this type of driving. I wish the HUD would display what gear it is in.
