got a flat tire, thought no problem i'll change it myself. Have to pull back seats to get jack and tire iron, then get out the manual to locate how to use this tiny jack, have to open back by tailgate to insert rod to lower tire, very difficult to get under car to place jack under it. Finally did get it.But this was all done in my drive way. If I ever got a flat on the highway, I would never be able to change the tire, Nor would anyone else, It was an extremely difficult process,Chevy needs to rethink this process,Make it much simpler to change a flat, as it should be.
