Failure to communicate with tcm/ecm/pcm. This problem has caused several occurances where driving the vehicle has been hazardous. Because of either the wiring or the tcm itself, I, the consumer, have nearly been in 2 accidents. At first I was told that it was the power steering assist module. Replaced that and problem still occurred. When the problem occurs, the gauges jump up and down and completely stop working (speedometer and tachometer), transmission shifts extremely hard when accelerating, power steering illuminates in the data information box which in turn causes loss of power steering (replaced power steering assist motor, issue still happens, 1 occurance of loosing power steering and being able to stop before going off the side a mountain when trying to maneuver a right hand turn), check engine light illuminates, when shifting from park to reverse, reverse to neutral, neutral to drive, the transmission engages very hard and results in an audible "clunk". 1 occurance of vehicle switching gears into neutral from drive, while driving (shift lever still in drive position),passlock light also illuminates in dash. Vehicle consistenly acts as it is going to stall (headlights and dash lights dim). Checked alternator and battery, both in optimal working condition. Presenting diagnostic code include p0700 and u0100. Vehicle maintanence has been performed at 3,000 mile intervals but has been pulled off the road due to the 2 occurances of near accidents. Vehicle has been experiencing issues for several months prior to removing it from opperation. I know for a fact, this Cobalt is not the only one having this issue.
