Total quoted repair cost from our local dealer.

Dealer just confirmed that GM is "out of AC compressors." Not sure if all 2019 to 2026 trucks use the same compressor, but a shortage like that is hard to believe.

From what I've seen, they "could" sell the switch but designed the assembly such that the switch can't be readily removed and replaced without removing a plastic locating pin. Sure appears aimed at forcing the end user to purchase a $900 shifter assembly instead of a $20 switch. Thankfully I still have some extended warranty left... this one has had warranty repairs almost every 5K miles from the day I bought it.

I'm well aware of the typical bathtub failure curve, but plotted, this truck has been more like an elevated straight line. It started days off the lot with misfires that GM couldn't solve for almost 2 years, and steadily continued over the last 5 years with repeat replacements of wiring harnesses, camera modules, cameras, parking sensors, head unit, rear windows, rear leaf springs and bushings, lower control arms, a radiator, and now an ac compressor and a column shift assembly.

Dealer reported a failed shifter module assembly so the whole shifter is getting replaced. Yet another premature repair… up to $12,000+ in extended warranty payout in only 5 years and 80,000 miles!

According to the dealer it’s an internal leak/failure of the compressor. Again, another failure that shouldn’t happen at only 5 years and 80k miles. For some reason the compressors must be hard to come by right now, because the truck’s been at the dealer almost a week and they just located a compressor at another dealer several states away today. We’ll see if this fixes the issue.

5.3 Sierra with approximately 80,000 miles had a radiator replacement about 6 months ago which required pulling the AC condenser and a vacuum and recharge on the system. AC cooled fine until about a month ago, when it would suddenly start blowing lukewarm air for 5 minutes at a time at various points throughout the day, then suddenly resume cooling again. Sometimes its when stopped at an intersection and other times while moving. I've read about the internal electronics in the compressor going bad on these trucks and not cycling properly, but sounds like many dealers just chase AC issues with a parts cannon. Also wondering if they charged it correctly when the radiator was replaced. Is there an easy way to see if these electronically driven compressors are engaging properly, or to check for freeze up, etc.? Dealer usually wont do much unless they can replicate or I can show them a video of what's going on.

Apparently it doesn't trigger a fault, at least according to my dealer, but in one month its gone from once or twice a week to several times a day, so you can catch it on video and its likely to be seen by the dealer. I've heard some have replaced only the switch, yet others have required full shifter assembly replacement to the tune of $900+?

Agreed, it definitely appears to follow the EV motif, especially because it appears to follow the rockers on the Sierra too.... but has to be a cost saving measure as well. Between rocks and bugs and driving 20K+ a year on Texas highways, I can keep the painted front ends looking decent with PPF and a thorough periodic cleaning, but the unpainted plastic cant be coated, or cleaned up well. The same plastic underneath the bumpers on all our current generation trucks is beat to hell after 2 years or less on the road.

Whoever greenlighted the work truck matte black front bumpers on every trim but the AT4X should be fired! I was hoping that was an AI mistake, but just realized they were on every model of the 2027 Silverado too. Some parts of the interior do look premium, but the Denali Ultimate dashboard looks like an afterthought. At least they appear to have lost the microfiber the high end Silverado models showed, but the '27 High Country dash looks better than the Denali.

Periodically having a rear passenger door that wont open from the outside. Thought it was the lock mechanism so toggled the locks and door was still stuck. Finally pulled pretty hard on the handle and got it to open, but felt like it wasn't fully unlatching or was suctioned shut, despite other doors and windows being open at the time. The next time it happened, it took me pushing from the inside to get the door to open. Any suggestions?

Are there any conditions that you could re-create the shift to park message for the dealer, or some other method to test and prove the switch is failing? Truck is still covered by a GM extended warranty for another year, but the message is only coming up a time or two every other week. I've seen the threads about the switch being the failure point, but as usual, the dealer says they cant do anything under the extended warranty without "re-creating the issue." Assuming having a phone ready to video at each shut down is the only option on the table at this point?

Same… have been used to reaching in the door or window and using the light switch for years. On the glass center screen makes zero sense ergonomically but I can only assume some young engineer or accountant justified it by saying they’re automatic and no one uses the switch.

Not based on the new photos I'm seeing. Car and Driver posted additional photos that shows an auto stop start button left of the steering wheel.

Car and Driver is reporting wireless CarPlay WILL remain, and they posted several additional photos, including a left knee shot, but the only hard buttons there are e-brake, auto start stop, tailgate and cargo light. Also definitely looks like High Country and ZR2 get micro fiber on the center of the console lid and the ZR2 possibly also on the seats.
