When i hit a bump, speed bump, water, rain, anything of the like, i get the stability control light and abs light, yesterday 9/13/79 i recieved the 4wheel drive maintence needed as well when i had the trailblazer in auto 4wd, this isn't the first occurance and i believe this is going to end up being a danger to people especially those in the northeast, as a former firefighter i have seen what these failures can do not only to the car but to the people as well, for this i believe there should be a recall, so as to repair these issues. and make the chevy brand reputable again.
