My son is a mechanic and early in his career tried working at dealers and couldn't deal with their way of doing business. Worked for independent shops, now works for a GM sub contractor. Works only on new vehicles doing whatever GM wants. 

He has been replacing defective modules on new Corvettes.

Everything is by their book. You beat book time you make more money. Been to General practitioner lately? I’ve had the same one for about 30 years. I go yearly for my blood pressure meds. My visit last about 10 minutes he stands at his computer asking questions typing info. He puts his scope on my chest, back, neck. Back to the computer, boom runs out. Nurse comes in blood work, boom I’m out. Maybe 1/2 hour total. Now don’t get me wrong. That suits me fine. The downside if you have a semi urgent problem. Urgent care is where you go. A doctor, dentist appointment within a week not happening. Same with dealer oil changes appointments only. The two dealerships I use I can see them working. Same with the valvoline quick lube I use. My next vehicle purchase probably will be one of those two.

I can see that with these mega corporate dealerships like Sonic Automotive Group who don't care that they lose a small handful of customers due to a crappy service department experience because they know they can lure 10x that number through the doors with some sketchy marketing gimmick.

 

 

The smaller mom and pop dealerships on the other hand ought to have better service departments because it's their name and reputation that's at stake.

In our case it unfortunately was one of the smaller family owned dealers left in our area that we purchased this truck from.  There are only two family owned GMC dealers left in our area, one of which is even worse, and the other is not taking any vehicles for service that weren't purchased from their dealer because they are so backed up with repairs.  The owner of our current GMC dealer recently told a business partner of mine that they can't find decent mechanics, and complained about turnover being their primary issue.  I call that at least partial BS, because from my experience, there is clearly a lack of proper management and quality control measures.  I recognize the dealer's aren't responsible for faulty designs and product, but they ARE responsible for the multiple times they've returned my truck to me with other parts broken or damaged, or incomplete repairs, OR when they diverge from proper means and methods.  I despise every time I'm in for service and overhear an advisor telling (primarily women) that they need a fuel injection service on year old vehicles.

Hiring and retaining techs is a national issue with a lot of aspects. Pay being one but poorly run dealers with horrible middle managers that create toxic environments is certainly a big one. The dealership service model is broke but theres too many people profiting from it to want to change it. They are the architects of their own downfall and GM is content to stand by and watch them fail.

There’s a few reasons I’ll probably not buy a new GM product from my last dealer. I’ve bought a few from this dealer. They sell Hyundais too. I’ve bought a few of those there. The first issue was they wouldn’t pass my truck because of moisture in the headlight. I had four in those 2000-2006 models that did that. They’d clear up on their own. The valvoline quick lube didn’t have a problem with it. The decider was while I got an estimate for brakes on my Genesis that was very competitive. I walked across the lot to the GMC shop and asked for a brake job estimate for my truck. My truck inside and out could pass for almost new. It’s that clean. Without even looking at the truck they said if it’s over 15 years old they don’t service them. I answered Honda does. I guess you don’t want my business anymore.

The manual does not call for transmission service at 45k, apparently considered a sealed system. Had mine in for routine service and was told needed fluid/filter change. I checked all documents I could find and it did list the transmission service for severe use which is not me. Posted on here and most said it was a good idea and good preventative maintenance. So on the advice of those here I had the service done. 
Dealer completed the service but would not go into reverse when completed. The valve body had checked out somewhere during the service. Don’t know if the service caused the issue or if it just picked that time to die. After about a two month wait I got my truck back with a new transmission. No valve bodies available, on back order with all dealers (several posts on here with their horror stories like this link)

so dealer just replaced the transmission. 
In the future I think I will be careful in doing non-recommended service/maintenance.

The "sealed system" moniker is false. Like so many other terms in this society it has been co-opted. The trans is serviceable and will require maintenance just like its predecessors. The difference is the method of filling and checking the fluid. No one can guess what GM's motivation was for those changes and I for one consider them a step backwards but that doesnt at all mean that these transmissions dont require servicing.  Page 392 bottom left. I tow a lot with my truck so I follow the severe schedule. https://contentdelivery.ext.gm.com/bypass/gma-content-api/resources/sites/GMA/content/staging/MANUALS/8000/MA8640/en_US/4.0/24_CHEV_Silverado_2500_3500_HD_OM_en_US_U_84989060B_2023JUN02_2P.pdf

A friend who went to some dealer tech training way back when said it was mentioned that the motivating factor for eliminating the trans dip stick was safety. There have been many instances where vehicles burnt to the ground because atf spewed from the tube and caught on fire.  Most of those incidents were from owners negligence such as not seating the dip stick correctly, ignoring overheating or over filling of atf fluid.  Weather opinion or fact, does make sense.   I do know someone that happened to with his 454 dulley, burnt up all the under hood wiring.

Wise, because we all know GM spares no expense to make sure the fluids they install are the very best available.  They won't use a low bidder.

From what I am told by people that work there it is usually good stuff, or at the least good enough to get past the warranty
