You are freaking out over "what if" and "might" and "maybe"???
It really is a sign of what may be "likely" because of the abundance of them. 90 TSB's and multiple recalls, wish I knew the actual number, and GM is asking us to dole out hard earned money for rigs that are supposed to have already been put thru the wringer to avoid these problems. What they say they do before rolling out the new models and what is actually done may well be just "double talk". Don't get me wrong, I love the GM brand and have for years but I have seen this pattern before many times over the years and I am not the only one who doesn't recommend buying the first year or two of a new model because they actually have not been thoroughly tested and analyzed by the powers that be. I will not buy another brand of vehicle but there is also a reason I have read on here that the best years of the NBS 2000-2006 models were the 2005 and 2006 years. Hell, I read in another thread that a member here made sure he bought an extended warranty just because of the first year model of 2015 rig he bought and he laid out a list of what had to be corrected that backed up what he said. I know other manufacturers have similar problems with new model years but that is no reason to think it is ok for GM to also be in that group. I feel lucky that I did not get that 2021 Z71 but I may jump for one in 2-3 years when the well known and documented bugs are worked out. Again, I will not deviate from the GM brand and I will always steer a prospective vehicle buyer to the GM brand but I will also share what is being said here in this thread and other threads.
