My truck was bought new by my cousin and not even a year having it the frame started rusting badly. Now we own it & it is scary to drive the frame is so bad rusted. We have put so much money into it it’s ridiculous & cant afford to anymore. It’s a danger for my family to drive it. I’m scared to drive my 8 year old in it. It’s causing more than the frame to rust. We’ve replaced gas lines, brake lines & so much more. I wished GMC would fix this problem & repair all vehicles this has happened to.

I purchased the 2016 GMC Sierra new. From the very start I felt there were issues with the transmission. I took the truck in for the shaking, vibrations and clunking in the trans with 5058 miles. Over the next 36 months I had the truck in 7 times and 3 different dealerships to get the trans fixed. Only once did they really do anything where they changed the fluid. I lived with the issues after the warranty expired as GM would not do anything to fix it. Now at 66,000 miles the vibrations have gotten so severe I am afraid to drive the truck. At no point has the truck not had vibrations, only they have increased. And now I have had 2 check engine warnings both dealing with the trans.

- #11438295October 26, 2021SERVICE BRAKES
The vehicle recently had a recall repaired at the dealership. I subsequently took delivery on it as a BRAND NEW UNIT, and the brakes are extremely soft; to the point where I must depress the pedal to the floor to get it stopped even at slow speeds. I hoped it was just an air bubble from the repair; but the fluid levels are full and the dealer had no ideas on what could be wrong at this point. I have a great relationship with this dealer, and we’ll continue working on it. But GM is releasing absolute trash lately and I fear that some poor family will load up, trusting these vehicles, and be badly injured or killed. After 200 miles of driving it back to my residence, both at highway speeds and residential road speeds, these brakes have not improved; ruling out an air bubble. I’m worried it may be associated with the recall that was previously remedied.

While towing our trailer, truck went into reduced power mode, regen message displayed; check engine light came on; loud bag occurred and hissing from under the hood. Truck slowed to 3 mph so we pulled to shoulder and turned the vehicle off. Truck had blown the hose off the the turbo. We reclamped and restarted. Displayed check engine light, reduced power & regen message to keep driving however truck wouldn’t go over a 3mph crawl. Truck lost all power, everything shut down and wouldn’t restart. No dash lights, no error, no crank, no power. We were dead on the highway in the truck lane while towing. This Truck goes into reduced power mode every time it tries to regen and we have had it to the dealer multiple times however, the problem continues to get worse. When it does regen, sometimes it takes hours. Dealer says needed a manual regen & that is their solution. Yet problem persists.

-Engine gas consumption states 21 MPG Highway, 17 MPG combined and 15 MPG City. -When I started using vehicle during the first weeks and months the best MPG I could geta at the highway was 18.5 MPG with top-tier gas. -Ever since I bought the vehicle, the gas MPG have gone down around 0.5 MPG. The vehicle feels that it has to use more gas in order to perform the level of task everyday. -The motor oil pump at times moves down from the 40 mark to the 20 mark when idle at traffic light and it starts moving, it temporarily goes to the 60 mark. At other times when idle it stays in the 30 mark. -The transmission is an 8 speed automatic. It has issues shifting 1st and 2nd gear, and at times 3rd gear as well. When driving at slow speeds like in a traffic jam, mall parking, do a u turn or when you slow down at the traffic light and then turns green and you start accelerating again it feels harsh on gearing up and down. -This vehicle has the Active Fuel Management (AFM) system, it turns on even at slower speeds and you feel how the engine and transmission struggle to accelerate, go a gear up and push the vehicle with only 4 cylinders. Like in manual transmissions when you accelerate on a higher gear than the correct one, it takes forever to accelerate and properly change to 8 cylinder and establish the correct gear and ratio. -Even if all 8 cylinders on it it feels like if I am running on a smaller engine. -There was a fix done to the transmission for a valve, but the vehicle still runs the same as before. -There is a knocking noise starting to build in the engine. Best mileage I can get driving the same and gas is 13 MPG combined. -The recent safety recall for the breaks is actually making the breaking worse than before. -My vehicle is 2016 GMC Sierra All Terrain V8 5.3L 4WD Z82 with 36,500 miles on it and is doing all this and its getting worse little at a time.

While operation my 2015 GMC 1500 DENALI Pickup at normal conditions my vehicle produced a engine light. I was three blocks from my office so I proceeded there immediately to have my vehicle scanned for codes. This is where I found out that cylinder #7 had an issue. This cylinder is part of the AFM system. I had the vehicle towed to Galles Chevrolet for diagnostic services and an estimate for repairs. Up receiving the results (which) I will attach. Bank 1 and possibly Bank 2 lifters and springs have failed. Thus possibly cause damage to the cam shaft. While I am aware that my vehicle is out of powertrain warranty (5 years / 100,000 mile), my vehicle only has 52,000 miles on it and very very well taken care of at all times. I am also aware of a class action law suite that pertained to the same exact issue on gm products from 2004-2014. Also service bulletins were produced by GM pertaining to this issue. Now I have been out of service of my vehicle for 3 1/2 weeks not to mention a potential $7000 repair, that should have never been in the picture! Poor quality control on products for potential profit gains have cost many many customers pain, anguish, and money.

Sitting at a traffic light, I could smell smoke. My Entertainment dispatch was showing a Green lightening bolt, and I knew that my phone didnt work on the center console charging pad. I lifted up the center console pad, and it was completely full of smoke. It appears that a bad design by GM has the wire running up to the wireless charging pad, in the same path as the lid hinge, and it appears that over time, the hinge has worn away all of the protective material on the wiring harness. The wiring harness is burned and charred for as long as the eye can see. Unsure what has been affected by this yet, as it goes into the shop tomorrow.

Received a air bag recall notice . I scheduled a appointment with Hall Buick GMC in Tyler Texas 10-18-21 at 11:00 am . We showed up to service Dept. The young guy checking us in told us that 92% of the time they will crack the dash when getting it removed to do the the air bag recall work and the dealer is not responsible for any damage. I told him to get his manger so he did. We talked to service manger John Mackey he told use the same thing that the dealer is not responsible for any damage done to the dash like cracks or breakage while doing air bag recall work. I told him as you can see this truck has been garage kept since new and not in the sun. He said I can see that . I told him per the paper work I received if not fixed it may cause serious injury or death to passengers .Who's going to pay for that. He said GM and Takata. Is there any one that can do the air bag recall work without damaging the dash.
