Driving down the highway @ 55mph and the power steering cuts off, the power brakes cut off, the abs light comes on, the turn signals start going on and off at random, the gauges jump up and down nonstop. I just picked up my car and was told it referenced TSB#08-07-30-021 (NHTSA#10025402). The check engine light is still on because of this problem. The shop referenced the following error codes from the check engine light: p0575 u7300 u0121 u0140 thank goodness no one was behind me or around me at the time because I was unable to properly steer the vehicle, brake, or accelerate. This is a major problem that should be addressed by gm.
The traction and abs light frequently comes on. I'm not sure if it something that I should be worried about, or if it is something that just happens.
