I owned 2017 Sierra 1500 with the 5.3 liter engine and 8 speed transmission. I traded it in at 55000 miles for a RAM 5.7 liter Hemi. The a/c condenser went out at 20000 miles would have cost 3000.00 to fix. (Still under warrantee) The concern I had was the 8 speed transmission. It shifted really hard in 1 to 3 gear. There was an audible clunk and shudder. GM continually denied they have a problem with that transmission, although it is no longer available and if you go internet surfing you will see lots of sites complaining about the same issues I noted above. I will never buy another GM product.

I just replaced my transmission on my 2015 GMC Sierra Z71 4x4. Replaced all 4 shocks as well. Now it drives super. Damn smooth. Like it’s brand new. Shifts are smooth as butter 🧈. I had a super duty transmission installed.

Thank I was really looking into buying a 2018 GMC 1500 Denali. This totally changed my mind.

I'm glad I saw this. I was looking at a white 2018 GMC Denali with 80k miles. It's a shame. These are great looking trucks.

I own a 2014 Sierra and I approve this message, I can’t tell you how many issues I have had since owning this truck, it has really been a nightmare. GMC is trash and I will NEVER buy another vehicle from them again.

I have a 2014 GMC sierra v6 and the oil gauge fluctuates even after the truck is warmed up. Dropped below 40 once but mostly it stays at 40 while idling. When driving it goes between 40 and 70. Any help is greatly appreciated. I’ve had the truck for three days and I bought it for $24, 000. I think I messed up after reading these comments.

The radio doesn't work anymore shakes at lights ima try to sell it before the engine lights come on good looking truck though but i think ima get a ford

It's a shame since these are such beautiful trucks, especially the higher trim models, dang!

[knightstemplar]

I have vibration around 70 mph. Hope, nothing else breaks, Lord willing.

I own a 2018 GMC Sierra. Love the look of the truck and the ride is one of the smoothest ever but it has plenty of problems. Radio went out possibly 2400 bucks to fix. Water pump just got replaced at 100, 000 which is pretty shity . The AC randomly doesn't work along with my temperature gauge and the cooling fan stays running after you turn off the truck. Not to mention the transmission does seem like it shifts weird. It has the 8-speed automatic. Really love the truck but what a pain in the butt probably won't ever buy another GMC or Chevy again

Currently waiting on the dealer to get back with me on a 2014 with decentmiles. Im starting think the dealer can just keep it. Not a GM dealer either.

[jerryhernandez]

No mention of the 2015 burning oil like crazy, doesnt smoke, just likes to consume alot of oil.

[nathanaelrussell]

[clarencepowell]

Damn I just got a 2018 sierra z71 4x4 😂😂😂😮😮

Sounds like any other modern vehicle, especially trucks and anything running a V8 motor.

The GM AFM system has been a nightmare since it was introduced. If you ever have to do a top end rebuild due to afm lifters or your regular lifters, just do an afm delete and be done with it.

The transmissions in these also suck - that’s really the biggest issue I see with these trucks overall because there’s nothing you can about it other than replace it and the torque converter, and pray it holds on long enough.
