At first glance truck really grabs your attention ! Then you buy one "MISTAKE" headlight's blew out at 10,000 miles , 16,000 running boards had to replaced peeling like a sunburn , now at 17,000 miles front bumper is loose slid at little to the right inside bolt poked out a dent , chrome on emblems is peeling I can say I never had a problem with dealership "WHY" because they look at truck and say no problem we will replace the defected parts sounds great but what a inconvenience to keep returning to dealership it's been one year with the vehicle once all is fixed time to get a trade in value and go back to Tundra !

I should start by saying I have the 5.3 V8. It has more than adequate power. The payload exceeds the 2007 I previously owned. Because I have radical lug mud tires, my fuel mileage is only about 16MPG. I expect it will increase when i put street tires and quit hauling heavy loads or pulling a trailer. It has the trailer towing pkg, 4 wheel drive, and I believe it has been lifted, since I can't reach over the bed to access the bottom of my tool box. The BEST I have done is 20MPH but it is avging 16. i am running 275/75/18 tires. It also has the locking differential, a must on a 4x4. The trailer brakes are integrated into the dash, I love that. In fact the only thing it doesn't have is a telescoping steering wheel, but it does have adjustable depth pedals. It is as if I custom ordered the truck, I LOVE IT!! I STILL love it. Switching from the mud tires did increase the MPG. I average about 17 in town and 20 on the highway empty. It has a 4" lift. I've driven it more I love it so much. About 15k instead of 10 over this last year.

Got my truck in April '15 and loved it - until it got hot outside. I've had two F-150's and a/c would freeze you out. Here in Alabma summer's are very hot. A/C blows hard and very cold, briefly. Then the A/C cooling stops while the hard blowing continues. And since we have such hot summers it feels like hot air blowing on you. It does this back and forth continually. Of course once the truck cools off enough then it not so bad. But it's a good 10 minutes- long enough to start sweating! It's as if the compressor switches off and on while the blowing remains the same. Dealer kept it two days and said it was working normally. I work indoors in an extremely cold business and am a slim guy so when I leave work I'm not overly hot so sweating my rear off on my drive home is unacceptable. Im wondering if the dealers hear this a lot and know it's baked into the design. Either way I will be trading it near years end when prices drop on 2015's. In the deep south with our long, hot summers and high humidity good A/C is critical. UPDATE: A/C still sucks. Truck has always had a vibration at HWY speeds which I attributed to the original tires. Finally after 2 and 1/2 years I needed new tires. Got a set rated the best for All Season/ HWY for my size and truck still vibrates at HWY speeds causing the change in the center console to clink! I will definitely be getting an F-150 when my lease is finished in July 2018. The A/C issue is a real deal breaker for me living in the Deep South.

SLE/SLT REVIEW w/ V6-V8 compare

What you need to know from someone who know cars and trucks. I've driven both the SLE & SLT models in the crew cab both in the V6 and the V8. The issues right off the bat for myself (someone who probably won't tow more than 5,000 lbs) is that the V8 (5.3L) can tow more, has more HP, and torque and WILL have better resale. Really quick on the V6, the power, responsiveness, torque and capacity was more than capable of satisfying most buyers. Onto the truck I purchased, the 2015 GMC Sierra V8 SLT short bed. I absolutely love this truck. From the power, torque, comfort, to how absolutely quiet the ride is... I'm absolutely impressed. I'm 28, a homeowner and a homeowner. In my few years on this planet I've owned 9 cars; SUV's, sports cars, trucks, and finally the GMC. My dad is a huge proponent of Toyota and so am I but this truck is a cut above the rest. INTERIOR The interior is absolutely amazing. In both SLE and SLT models you get the stitches dash and steering wheel which is both stylish, and sleek. I could do without the ugly silver accents surrounding the 8" touch screen but I can survive. Both the bench and bucket seats have their benefits. I love the bench but the middle seat is hard (due to the compartment underneath) but oh can still seat 6 people... but when will that really happen? and it's not comfortable. The bucket seats are amazing, in my SLT model I have power seats and leather and so far after 4,000 miles they have held up well. The electronics and capability of the truck are outstanding and expensive but amazing. The lighting in the vehicle is almost spot lighting and recessed so the light will not bother the driver when turned on... and it looks amazing when it's dark. EXTERIOR The truck looks better than most any other truck on the road. This truck has a smooth suspension and on mine and I have a Z71 and the ride is amazing, smooth, classy and responsive. The tailgate lowers slowly and has bumper steps which are nice. I love the four door look, the bed, and it's just all around sexy. Overall - the truck is great... MPG is industry leading for a Crew Cab V8. I average 20ish on the freeway at 80 and 17 in the city with my moderately heavy foot. I want this truck to start coming pre leveled instead of having to buy a 1.5" leveling kit. The truck also deserves better reliability ratings similar to Toyota... I'm hoping they figured it out and in 7 years I can still say my truck is perfect!

Nice Ride needs a little more refining

I bought this truck in April with 20 miles on the clock. Interior is a major set up from the 04. The touch screen info system takes a little getting use to but is not too complicated. The voice activation software need to be improved, takes several tries before system understands what you want. The setup in the G8 works very well, so GM should have it perfected by now. The WIFI hot spot was ok but not something I would use regular enough to keep. The resolution of the backup camera is good and I like the scaling on the display, keeps things in perspective. The ride is a little on the bouncy side and road noise is minimal. I have the 5.3L engine with trailering package. Power is good but transmission seems slow to shift when in town driving around 30mph. Have not had any service or equipment issues, only 4XXX miles mostly highway miles. My only true peeve is getting in. I did not get the step or rail so even with my 6'.2" frame I have to climb in but getting out is a breeze.
