These trucks are all new from the ground up. Everything is improved. No more numb steering feel, no more spongy brakes, no more quirky looking interior and dash. The suspension is a dramatic improvement. Those that hated GM trucks before should take another look. I never knew GM could make such a quality vehicle! This is one comfortable refined truck and will give the F150 a run for the money.
I've owned the truck for a week. And true, it may be a little soon to offer a really unbiased review, but so far, this truck has impressed me beyond words. The truck is extremely well constructed from the inside out, and at the SLT trim level, offers a lot of things found in most luxery cars. With lots of electronics, that could potentially be a problem fixing on your own if needed. The active fuel management convinced me the most to purchase this full-size truck. Among all the other V-8's out there I researched, the 5.8 had the best fuel economy. And with GM's 5yr/100,000 standard powertrain warranty, that measure of commitment was certainly more piece of mind for ownership.
I just purchased this truck this month. What a good looking vehicle! The truck handles very well, and the new design is just great. The interior is roomy and the controls are very user friendly. I ordered the Stealth Grey color, which is very unique. I would have never purchased one of the older model GMC trucks as the interior and exterior has remained the same for years. I also like the 5 year 100,000 mile power train and engine warranty.
I just bought my truck a few days ago. I got the vortec max SLT. I was worried about such a big engine and fuel economy (6.0 liter) but when under moderate excelleration or on the highway it only uses 4 cylinders giving it better mileage than my mini-van that I traded in on it. It is very comfortable and the fit and finish of the leather and brushed aluminum trim competes with a Mercedes or BMW. The new design is way ahead of anything else I have seen on the road, when people see it they can't help but notice it's size and intmidating looks. Yes I also got it because I have neer owned anything but a GM automobile, but after driving it around I know I made the right choice.
The new body style GMC Sierra with a 5.3 liter V8 has some oil consumption issues. My truck purchased new with only 30 miles on it, now with 26,000 miles on it and 3 years later, burns 1 quart of oil between oil changes. I suspect that the all aluminum block design probably has some oil ring clearance problems since I do not have any external leaks yet. Although there is no blue smoke coming out that can be seen, does'nt mean that it is not being burned. GM should do better here for a $46,000 truck. I am sure that the Suburbans and Tahoe owners are experiencing these same issues with the oil and 5.3 liter V8. I won't be buying GM again. Switching back to Ford.
With traction/stability control off, anything more than 1,500-rpm lights up those 20-inch tires. I love the broad torque of this V8. Also, it doesn't seem to run out of horsepower in the upper revs, either. It feels as if it could keep pulling beyond the 5,500-rpm shift point. Shifts are quick and clean. FYI: you can get an extra 500 rpm out of the engine in manual-shift mode before the 6,000-rpm rev limiter kicks in. We tried to utilize this, but timing an electronically requested upshift proved too difficult, and with a 6.5-sec run to 60 mph, why bother?
The brake pedal is neither too soft (as GM trucks once showcased), nor too firm. There's actually enough feel and pedal travel to modulate pressure and effectiveness prior to a full-ABS request. There was some fading feel by the fourth stop where the pedal travel grew closer to the floor.
With StabiliTrak off, the pickup exhibits pretty remarkable balance right up to the point where front wheel hop and understeer begin. In the slalom, we felt the steering was a tad light, but still accurate and effective. The overall steering ratio is a little slow, too, but I never managed to "beat" the power steering pump when I needed to countersteer. The truck's attitude remained remarkably flat through the transitions. FYI: OnStar called me after the first slalom run, saying they had detected a collision and, after ensuring them there was none, instructed me on the collision notification reset procedure. I think I've finally decoded the notification trigger: countersteering (i.e. car is pointed in one direction and the steering in the other).
