It is crazy, but I see the rotor thing probably every other month here in the shop. "Hey, I need my brakes fixed, they quit working." "Ok. Did you hear anything before they quit?" "No, they just quit one day." Uh huh.
I have had 2 of those problems with my 98 Riviera. The steering wheel rocking from 2:00 to 8:00 is a very common problem with the 95-99 Riviera steering column. The pivot pins for the tilt fall out. The other problem I had was the spring perch on the strut rotted out and the spring came down and rubbed the tire.
Most of that stuff is not that weird, just mostly stuff that was allowed to go unfixed for way too long. But a couple of those were just wacked. The car driving that was clearly in a bad accident. Or the brown goo coming out of the radiator.
