Hello from Grayson County, Texas.
I'm driving a 2007 GMC Sierra GMT900 crew cab but I'm awaiting news on my order of a 2014 Sierra SLT with a 6.2L and the Max Trailering Package.

 

At this moment, I'm sitting in my RV trailer at a campsite in Lake Murray (OK) State Park.

 

Greetings to one and all.

Welcome! Out of curiosity does your 2007 have active fuel management and if so, is your truck consuming oil? I had a 2007 silverado I just got rid of because that problem started showing up.

Yes, I have AFM... have 76K miles on it... no oil consumption. I probably haven't checked the oil more than 4 times in 7 years since the truck always makes it to its next oil change without losing any oil. I have a 3.73:1 rear axle and tow a 6500-6700 lb. RV trailer about 10 relatively short round trips per year.

Gotcha. Yeah I first noticed mine around 95k miles when I went to start it one morning and the low oil light came on. It took about a quart. It was due for an oil change so I went ahead and did it and the mechanic said he found a small leaky seal in the oil cooling line but to keep an eye on it. So I started monitoring the oil once a week after that and noticed the level continued to drop but there were no drip marks in the driveway at all. I crawled under the truck and it was dry as a bone. That's when I got on google and discovered the consumption issue. It starts slow only to progressively get worse. My trusted mechanic at the dealership confirmed the problem and said all I could really do was add oil until eventually the engine would have to be rebuilt or replaced. I decided since the consumption was still low at that point that it was the early beginnings of the problem that it was a good time to get rid of it. I had just put about $1800 worth of work into the truck when that issue popped up and I simply couldn't afford to keep fixing it. Anyway just curious. Sounds like your truck was making it longer like mine. Some people were having the issue pop up between 30-50k miles. It all depends on how often the AFM was engaged which meant the more city driving you did, the longer you could prolong the problem.

      Acceptably cheap tires?

      By Atlas · Posted

      Which one, the AT or AS?   Starfire is made by Cooper/Goodyear but at $85/tire I'd think I'd need to level-set my expectations that they may not even be round 😉 But you're saying they're decent?   I'm already into this thing $1506 in parts, fluids, etc. Totaled all my receipts today. $250 of that was replacing an EGR and MAP sensor that were probably fine, but I'm not going to return the parts since they've been installed. I'm cheap, but not that cheap. I use it, I keep it!   I may or may not make money if I sell the truck at this point, but, that wasn't really the point. And if I billed my time, I'd be hosed for real. My thought on the tires is I "might" put 1,000 miles on before selling it. I just don't want to put absolute junk on it, that doesn't do anyone any good. If the Solus solidly isn't junk, I'll definitely consider them.

      Is your l8t engine bay super dusty?

      I leave mine as is. I'm always a trip away from riding on unpaved roads. Dealer can clean it when they prep it after I trade it in for another new truck.

      I have these on two vehicles and love them. Pepper is one of them 😉

      4WD. Far as I know it came stock with P's and not LT's. Definitely planning to put P's on it, but stock is a 109 XL load rating so I should probably stick within that guideline.   No rebates on anything I can see at the moment. Discount Tire is offering $50 off, but Pep Boys is very competitive on price, and also carries all the off-brand stuff. Les Schwab always wants an arm/leg, but they do good work.   It still has the original spare. Goodyear Wrangler RT/S, thing looks like a tractor tire LOL!! How times have changed.

      2020 Sierra 2500 windows rolling down

      By JohnRoy · Posted

      2020 Sierra 2500 HD (base model) gas engine 4wd.    All 4 windows roll down on their own. Happens somewhat randomly after stop and engine off - when engine turned off, when walking away from vehicle before or after locks activated. Pulled the window fuse F14 Instrument Panel Fuse Block Right; the driver's side still activates from driver's side door panel; passenger and back seat windows activate from local switches on their doors but not from driver's side group of switches. Power mirrors don't activate with fuse removed either (same fuse for both circuits). Problem not solved.    How can they even activate with fuse removed but they are all still opening and can control from each door?  When they open on their own, I can shut them from the switch in each door, but they don't stay closed.    Seems to be activated somehow with key fob; something bumping the key fob in my pocket or just handling - removed key fob and took it far enough away and now the windows stay closed. Replaced key fob batty just in case, no change.    Sounds like some kind of wiring short or maybe electronics. Dealer will first replace electronic control module without checking anything else and I anticipate problem will still exist since their troubleshooting skills are limited to "do whatever the computer says".  In any case, keyfob seems to be activating the circuitry.    Surely I'm not the only one with this issue, but I can't find anything related on the site. What do yall think?   JohnRoy
