Truck has 60k miles in 4.5 years. Bit lucky that when I bought it the AFM chip wasn't available, so truck does not have cylinder deactivation. I almost never buy extended warranty as they only exist for the retailer to make money. I've never bought one for a vehicle. Maybe I should or I should stop complaining. Call me a purist who thinks that after making cars for 120 years, they should make them reliable. I worked in medical devices where selling mostly reliable products really wasn't acceptable. I do generally agree with your points. I may lease going forward as the older me is more willing to blow the dough.

L87 recall now shows complete at myGMC. Liberation didn't make next steps clear whether to keep or part ways.

I had a Sierra Denali w/6.2L from 2016-2021. Had XM antenna roof leak and clunky 8-speed transmission. Got a great price for it, so upgraded to the '21 AT4 w/6.2L. Separate from recall, no complaints. First time I ever had essentially the same vehicle back-to-back. Just ready for something different after nearly 10 years in a GMC truck. Thinking I am ready for new problems elsewhere.

Sell the AT4 and get a Raptor.

Not worried about oil burn long-term other than being annoying. Seems a common problem. Was helpful in getting pico-scope test performed. Hoping now it frees the recall so easier to sell. I'm ready to move on to something else.

I have a '21 Sierra AT4 w/6.2L. At approx. 55k miles and 5k past previous oil change, low oil light came on. Took 2 quarts of oil for any to show on dipstick. After next oil change, low oil light came on after 3,300 miles. Had it in shop cuz squirrel ate some essential wires. Complained about low oil issue. They offered to 'open recall' and perform pico-scope test for L87 propulsion issue. Test passed. They changed oil and filter, used 0w40. Should I expect this to clear the open L87 engine loss of propulsion recall? If it doesn't clear off my GM account, I'll check with dealer early next week. They also completed a recall for ECM software update. Wasn't aware of that recall.

Anybody try selling one to Carmax or Carvana? I've sold 2 cars to them. When I put a VIN in, normally get a quote immediately (including on a 24 year old Corvette I didn't sell them). Just put in my 2021 Sierra AT4 6.2L, which has no reported accidents, and Carmax responded 'We'd like to see your car before quoting. We don't see many like this.'

How many of those can they have sitting around? Think they took your original, swapped parts and will give it to the next guy?

Anybody else notice the smoke (where other models have chrome) colored trim on the grille and around front lights chips really easy and reveals traditional chrome color? I have it occurring in several places after 35k miles. Would this be covered under warranty?

Did you have to prove to dealer to get fixed or will they address simply because you bring it up?

If you'd have typed it once I wouldn't have asked. What is "launce"? If "launch", can't believe I'm reading this on this forum. You shoulda gone electric.

When my truck is close to empty, it will stop flow for first few gallons. If I hold pump handle to 3 o'clock, it will allow full flow. After a few gallons, I can rotate it to 6 o'clock to fill rest of tank. It's a workaround. For me, better than wrestling with service department.

Fair point. I'm not smart on this topic. I agree the GMC prices seem exorbitant. I wanted this option on my truck, but ended up taking one that was coming in vs. ordering. At the time, I think the option was $1,699. Probably still too much, but well below what they want for it as an accessory. This happens to be the right amount of sound for me. I'm not looking for bro-dozer level.

Now that you mention it, that does seem to be the trend I recall. Thanks for posting.

I have a '21 Sierra AT4 w/6.2L. I'm looking to get a GMC exhaust upgrade to the "performance" option. Loud enough for me. Seems I should be able to get a discount or coupon code. What is reasonable to expect for % and how often are they available? Alternatively, for same package could I do better buying elsewhere?
