You're an idiot, ONCE AGAIN. Quadrasteer had no problems (I mean, no major problems, like LB7-injector type problems). I dont give a shit if you "work at a dealer", you're still a friggin dumbass and you always will be in my book for making that stupid comment back in the "can tuners be detected" thread.
You've lost all credibility and no one in this thread should listen to you.
Ill say it again. Quadrasteer was a very reliable system. There were NEVER any accidents related to it "messing up", and there have never been any major failures. Anyone who says otherwise is an ignorant fool who is ASSuming things (because, OMG its 4 wheel steering, SO complicated, that PROBABLY MUST have a lot of problems, holy shit) or heard from "a brothers uncles best friends mailmain that his brothers uncles best friends mailman had a Q-steer truck and the computer 'messed-up' and swerved the truck into oncoming traffic and killed a bus full of 500 school children on their way to church"
Quadrasteer is badass. It wasnt common because GM initially priced it too high, and didnt market it correctly. People were turned off by the price, and lost interest. Not to mention all the fallacies about it being "JUNK". By the time GM lowered the price, everyone had forgotten about it. It really is sad, because it was an awesome system that made our trucks turn sharper than compact cars.
