So, thinking about buying one? Already did? well, before you ask 1000 mundane questions on the forums, lemme see if I can answer your questions. I love my SS and wish cars were all built with 400HP as a baseline, but the world is backwards.
Is it fast? Well, it's not slow, for 5000Lbs, I'd say it holds it's own against 60% of cars and 90% of other SUV's
Is it a good daily driver? Depends on whether your going to beat on it at every stop light & corner, or use the throttle with a little restraint. We all moan about 2 major design flaws, the transmission and the oil pick-up.
2a The Transmission is a little underrated for the amount of horsepower and the weight of the chassis, and they can occasionally die. Generally, if you are going to spend some time driving aggressively, leave the trans in 3, as one of the biggest killers is doing a 35 mph slow roll in D, then you floor it, transmission drops into 2nd, and bad things happen. Very bad things. There are built transmissions available, but not really needed until you move into serious mods (Camshaft, Supercharger, Turbo, etc) I have been on my stock transmission since 2008, still going strong after 100K miles, my mods are minor (tune, Airaid intake, exhaust, e-Fans) and many others have gone further than that.
2b The engine oil pickup, it's in the front of the oil pan and there are no baffles to prevent slosh on WOT from a dead stop, which results in the pickup going dry and starving the engine at high RPM, a recipe for a spun bearing, and many have had it, including me, at 30K miles. (Dealer rebuilt it) There are workarounds and fixes, You MUST do one of them, or you will eventually lose your motor!
Temp Fix:RUN 7Qts of oil! (Fill it to the squiggly on the dipstick) If you know the motor is 100% stock, you really need to run extra oil, hopefully you will spend a few extra bucks on a perm solution eventually. Choose from the following: Perm Fix #1 (Most Expensive) C6 Corvette Oil Pan, only applies to 2WD models, AWD need a different solution. This is the highest-end fix. But not the only fix. Perm Fix #2 (Mid-cost) Pickup tube relocation kit from PCMofNC, it moves the pickup to the low center of the pan, a proven fix that is good for 2WD or AWD. Perm Fix #3 (Lowest Cost) Kevin's baffles to reduce the sloshing and force the oil to stay near the stock pickup location. You need to join the Facebook group "Trailblazer SS 6.0" https://www.facebook.com/groups/TrailblazerSS6.0/ whole bunch of great guys on there, one is Kevin Hanson, he makes the baffles and they have a good reputation, It is a fix, it works in 2WD or AWD, and it's less than 50 bucks. I need to order one myself, I keep forgetting...
Most of the rest of the truck is damn near bulletproof, The rear end is stout (need to change the oil on a proper schedule) I don't know lots about the AWD parts as I do not own one, seems a 50-50 mix of good and bad, Gas mileage is, well, if you think 12 MPG is great than you'd be thrilled to know many get up to 14MPG!
The truck just looks badass (I'm partial to the old Jeep SRT8's looks too) and it gets noticed.
