general problems of the 2015 Chevrolet Colorado - part 2

I wanted to reach out to you on Chevrolet’s claim that their engine achieves 305 horsepower. While it may be true that their engine achieves this figure it does so at a stated 6800 rpm. The 6800 figure is important to note because the trucks’ red line indicating potential dangerous operating conditions start at 6500 rpm. So in essence in order for an owner to achieve 305 hp they would have to be operating their truck in a potentially dangerous manner. Even in the 2015 Colorado owner’s manual it indicates the danger of operating above the redline… “do not operate the engine with the rpm’s in the warning area. ” gm is stating that someone can achieve maximum hp only by operating the vehicle in a dangerous manner. . . . Really?! I believe it will only be fair for Chevrolet to re-evaluate their maximum horsepower prior to their engine hitting the redline.

Purchased truck in November 2014. Crew cab z71. Had problems right at 200 miles. They said the transmission has to learn my style of driving. At 2,00 miles transmission and engine still don't talk to each other. I can accelerate and 5 seconds or more later the transmission reacts. In heavy traffic, a couple of cars get between me and the car I was following before it reacts and I have to slam the break. Always seems to be in the wrong gear. Will chug a lot until it gets up to the speed for that gear. Took it to dealer at oil change and they reset the control module. After 2,000 more miles, took it back because it still acted the same way. Took tech on drive and was able to duplicate all my concerns. He said that there was nothing he can do and that I needed to wait for ecm calibration from gm. He said he felt bad for me. Surely I will get in an accident because of this slow transmission that is always in the wrong gear. Currently I am at 7,000 miles. The only thing the tech could say was not to drive it in stop and go traffic. . . . Seriously. Clearly this adaptive transmission is bull crap and gm probably knows they have a piece of crap programming but can't figure it out. Please figure out this shifting problem, because other than this the truck is nice. . . Too bad, because if they don't someone will get in an accident and hopefully it will not be fatal. Get rear ended because it doesn't accelerate when you need it to, or it finally moves when you are needing to break. Fix this now or at some point you will pay big. . . .
