2015 Sierra Denali 6.2 112xxx miles----- had since new.

List of repairs/issues:

A/C system failure-repaired

Drivers heated seat failure-element replaced

Nav antenna failed-replaced

Rear glass had to be replaced

Awful shuddering/vibration from transmission-repaired

All four magnetic shocks replaced both fronts failed around 55xxx and rears went bad around 80xxx miles

Trailer brake controller failed-replaced

Brake booster was extremely weak ran out of vacuum-replaced----not to mention this was very dangerous when backing into a parking spot or hooking up a trailer.

Both front A-arms-replaced

************Most notably now the truck recently dropped a valve at idle and cracked the block entire engine needed 10k repair plus plus.

Interior driver door harness went bad-replaced

Fuel tank evap sensor failed-replaced

Leak in moonroof headliner got wet-not addressed yet happened once

 

Learn from me! The truck tows a trailer about 4 times a year if that and is/was always bone stock with regular oil changes. Tired of the excuses from GM and everyone saying "****** happens" the quality of these trucks is awful and thats not even going into the quirks and issues with some of the repairs that were done (everything done at dealer). Do not buy these trucks and if you HAVE to have a GM don't buy the Denali its just a badge and some seat stitching (you do NOT want to have to replace the mag shocks for roughly 800$ a shock) not to mention the very sub-par rough ride they provide. I've ridden in many SLT's same generation and they are better riding trucks no question. Long story short stay away and don't go through what I did with a 60k+ plus truck. I love(d) GM but the company has left quality in the rear view mirror theres no excuse.

Hey sorry to hear about the extent of your repairs man. 

 

Did you actually pay 10k for another AFM emgine?

It’s looking like yes I’m taking the plunge on another AFM trash block. They even doubled down on AFM for T1 with dynamic fuel management that can go down to one cylinder…. I’d go new if they’d stop with all this “technology”. They claim AFM saves the consumer 5-7% fuel WELL with the amount of repairs you lose all those gains and then some. Plus if they want to use the environmental gain as the reasoning I would argue serious engine repair is less green LOL. It’s all about the money. Disgusted. And yes I realize any manufacturer you could have these problems but cmon!!!!

Joins forum, post some laundry list complaint threads, hmm..... Sucks that happened to you, but that is the minority. Most have zero issues with AFM (or most of the rest of the truck), so they aren't going to have repairs and get the cost savings with AFM. If you think the quality is bad here, go take a look at Ram or Ford, you will see the same laundry list. Grass isn't always greener, good luck but you are in the minority here (not saying it doesn't happen just not very often). BTW, you have an extended warranty, let them handle it...

Always amazed that folks think everyone else is experiencing the same thing with their trucks.

Both of mine run just fine.

My neighbor just got a new f150. It's been back to the dealer twice in two weeks. Now he said something is wrong with the screen on the dash.😩

It doesn't matter which brand forum you go to whether Chevy, GMC, Ford, Ram, Toyota, etc... you will find plenty of fan boys saying theirs is the best as well as those saying it's complete garbage. Every brand will have plenty of success stories as well as their share of problems. They all seem to be selling and I see plenty of each out there. I think fan loyalty is important but you need to decide what is important and find the brand that has the features you want and fits your particular niche. I personally prefer Chevy but my buddy has always been a Ford guy. JMHO...

      No Software Updates - Old Build

      If there are updates/fixes you want, you could pay to have the updates applied by the dealer.

      No Software Updates - Old Build

      By DaleB · Posted

      Hi all - my current truck is a 2022.5 1500 High Country 3.0. I bought the truck used last year. After doing some digging, I noticed that my truck's software is stuck on the original build from 2022. I have no available software updates. I talked to my dealer about this and they recommended not trying to force an update since the 36,000 mile warranty is expired. This is a big bummer since there have been many major releases since that have fixed small issues and improved speed/usability.   For reference, the current software build number is: full_gminfo37_gb-user 10 W158E-W164.4.2-QIH22B-563.3 158 release-keys Has anyone had a similar experience? Should I just forget about it and move on, or try a different dealer?

      Using zip ties but 2-3 they snap due to sharp edges. Just using a shoestring. Last longer. 🤣

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      I ordered the Snap On...waiting for it to come in later this week or early next week.   New front cover, new crank seal and new balancer are on. Water pump, pulley, fan, hoses, and plastics reinstalled. I can move forward knowing all my timing marks are dead on and the front engine is hopefully sealed better than it was. Take 2 with the water pump...trying high temp thread sealer on the lower bolts.   Rebuilt injector and new-new regulator is in, it looks like new. Top intake reassembled and all the bits are reconnected and snugged down.   Thinking about knock sensors again, I located both of mine and, there's your problem, Francis... The driver's side one is broke, plastic is bashed in, part of the wire is bare, and it appears to have been damaged like that for a long time. I saw the wire but didn't think anything of it. The knock sensor might not be my pulled timing issue, but it sure looks suspect. It must still be conducting, otherwise I'd expect a CEL. But perhaps with its sacred crystal inside exposed, jilted and dirty, maybe it's sending mixed signals. So I'm waiting for one of those and a new pigtail to come in. Pass side sensor looks good, except for the spark plug wire resting on it (!). The plug wires are healthy so it shouldn't be causing an issue, but I separated them and added zip ties to nearby looms to keep everything well apart.   So, I'm down to installing a knock sensor AND, oh, replacing the exhaust and cat. I actually think that's going to be fairly easy, it's all bolt-together, all new stuff from Walker is laid out on the shop floor ready to go. Hopefully have this thing on the road again for the weekend.   My luck? It will still be leaking oil, coolant, pulled timing, intermittent CEL for running rich, or it probably won't run at all -- because that's how this project has gone.   I've never worked on a vehicle so ...hurt? ...cursed? in my life. Everything has been effed with SO HARD, but I think...knock on wood...I've managed to undo all the backyard stuff and we're almost reset back to "just" an 80k mile, 30 year old Blazer.
