GM already has enough issues on their plate with their vehicles, including with front steering in the past.  Adding rear steering is more things to go wrong and especially with GM’s troublesome electronics and prone to glitching - I would pass on it.

Don't need it, don't want it.  Just something else that will go wrong and be unfixable, even from GM. 

I would "steer clear" of that type of system.  

I view it as a gimmick, and very unreliable considering it's made by GM.

Oh, are they bringing the quadrasteer gimmick back again?

I guess people forgot about the 1st time.

Know Gm it will be a big failure. 

Gimmick, but pretty cool. 

Money money money....moneeey!

From what I recall it didn't do all that well for acura either, but modern gm being the dumpster fire it is, I wouldn't buy anything newer than say 1996.
