It’s a 2017 but travel quite a bit for work so I am out of the 36,000 bumper to bumper. It’s got 60,xxx on it. Electrical problems scare me on a first year truck. Sent from my iPhone using Tapatalk

I am looking to know what if any the common malfunctions / issues were either the 2017 diesels. Sounds like a reasonable question for a GM forum. Sent from my iPhone using Tapatalk

You would have to talk the dealership out if it. They are trying to figure out what’s up with it on my dime. Sent from my iPhone using Tapatalk

I am a lifelong GM owner but I got burned by a 2014 1/2 ton GMC. At 103,000 miles a lifter rotated in its bore and the engine ate itself. It was a complete short bloc replacement. I wanted to get clear of that truck and I took a beating on it. I needed a 3/4 ton for work so I looked hard at the GMC diesels as well as the Fords. The new GM diesel engine platform scared me because I had just R&D’d a new platform for GM and ended up eating the cost of a short block. I really didn’t want to do that again. The Ford had a new body but the tried and true 6.7. I decided to gamble on the new Ford because I really didn’t want to buy another motor. I REALLY like the larger rear cab and how well things are though out with upfitter switches and the pass through wiring. That really is nice. The problem with the truck is it’s out of warranty and it’s Nicole dining me to death. The electronics are just not holding up. I have had def tank issues, now all of the BLIS and the backup cameras have died. Overall i like the truck but I am slowly getting back in the same boat I was in with my 1/2 ton. I say all that to ask this question. How have the new 2017 diesels held up so far. I know they make a ton of horsepower and they do drive nice but what are the weak points? Any injector issues like the diesels of the past? Anything I should know before I move back to GM? Sent from my iPhone using Tapatalk

The little town I live in will write you a ticket for just about anything. The the only way I can not speed through town is to set the cruise. If I put my foot on the pedal I will definitely be going faster than 30. Maybe this one will get me a little more street cred. Sent from my iPhone using Tapatalk Sent from my iPhone using Tapatalk

That's a sore subject. It's a 2014. At 103,000 a lifter on number 7 rotated in its bore and ate a chunk out of the cam. Of course it was 3k miles out of warranty. Luckily I have a good dealer and they got GM to eat half the cost but I was still out $3,800 bucks. I am going to run it until the motor warranty that came with the new long block runs out (203,000) and this truck is history. That should be sometime around January. I think I am going to a 3/4 ton diesel next. Other than that issue it's been a good truck. It spends quite a bit of time idling and at interstate speed with no real issues other than a total motor meltdown. I can say definitively that all the catch can stuff is just hoopla. At 103,000 miles the valves looked pristine and the head looked almost show room new. I got to see all of them first hand. Sent from my iPhone using Tapatalk

I found my mile per gallon that I lost. Sent from my iPhone using Tapatalk

What wheels are those? Sent from my iPhone using Tapatalk

I put almost 65,000 miles on mine last year. That's a few bucks I left on the table to look cool! With the 275/65/20's and no air dam I am averaging about 15.5 mpg. I decided to keep this truck and run it into the ground rather than trading it for a new model so I am going to try to up the mpg a little for the next 150k miles. Sent from my iPhone using Tapatalk

I wanted my 1 mpg back! I missed it. I drive a lot and it really will help my long term fuel cost. Sent from my iPhone using Tapatalk

Man there is a bunch of Mississippi up in this thread! CSMDavis are you just on every single forum on the interwebs? This is Garland btw Sent from my iPhone using Tapatalk

I did it and lost exactly 1 mpg in all around driving. I just put it back on after almost two years without it. Sent from my iPhone using Tapatalk

That's really not a bad idea. I am just about to add a compressor and tank in the back as well for general use. That would make the most sense. Sent from my iPhone using Tapatalk

I have had both and I will now take the Billsteins 10 times out of 10. MRT hooked me up to. Great guys to deal with. Sent from my iPhone using Tapatalk

I have a 2014 Sierra z71 package. It had a two inch block at the rear now. I want to add a 3 inch block in order to leave things out. I carry I bunch of work stuff and I have a camper shell on the back so have a bit of a negative rake. If I add the 3 inch block (net +1 inch lift) will I need to get a different length shock or will the Bilstein 5100's I have work ok? Thanks in advance. Sent from my iPhone using Tapatalk
