Do I like GM as a company? NO.... That's a known fact. Does GM make some good products? Yes. Tough to beat many of the cars, the Cadallic products, the Suburban, and the Corvette. Do I care for the trucks? NO, not one bit. I feel as a whole the GM truck line is dead last and dated. My personal perspective as a buyer, owner, and two time GMC truck owner.
Now for the Trailblazer it never appealed to me. Its ugly and it drives me nuts that the spare tire is visiable from behind. The few I know with them complain about the MPG, both are GM people and own other GM products. The exact comment from my friend Chad is "For what it is and cost I should have bought Stacy a Tahoe. My Chevy 1500 4x4 gets better mpg"
I know three people with them. I know for a fact one had transmission issues and I personally picked up a co workers sons and transported it 30 miles with a failed rear diff. I can not say how either were maintained.
I assumed they shared the same 5 cylinder like its truck sibling. I never looked at them that close because like I said, its ugly in my eyes. I had been around the Colorado and knew my way around under the hood working on my friend Dougs. I have been under a Trailblazzer on a lift at the shop I mentioned when they were replacing the engine. All I could think was how stupid it was that they ran the drive shaft for the front axle through the oil pan.
Yes, all brands break. I have had them all and have had good luck and bad. My GM cars were not that bad, just little annoying items like powe windows, horn, dash lights, heater blower motors, electrical sensors, ect. All in all good and never left me stranded. Trucks, not so much. I was a die hard GM person. Owned 4, my sister had 1, my dad has had 3 or 4 but overall the Fords, Hondas, Nissans, Toyota's, ect have treated us much much better.
