My comments on "learning how to park" were just meant to give some perspective. I was reading this posting thinking...are you really worried this much about this topic? The sensors aren't there...just like they haven't been there for the last 100 years.
Park the car 3 or 4 times and you should be comfortable parking it anywhere. If this is a must have for you, I would have expected you to verify they were there before purchasing the car.
As for the recall comment you made...I'm really hoping that was made out of sheer frustration, because that is laughable. Not having an unnecessary option on a vehicle is hardly a reason for a recall.
As another poster said...lighten up a little. The reason for the forum is to get advice and different perspective from others. Sometimes that comes along with a little sarcasm and jabbing. If this is your biggest gripe about the vehicle, I'd say Cadillac is doing its job!
