| While driving, my vehicle's warning system for the active handling & abs system activates during normal driving conditions. it is highly unlikely that both of these systems would develop a problem at the same time. upon researching this, i discovered that gm realized a flaw in the designing of the wiring harness that is contained within the steering column that is responsible. gm has designed a part to fix this, but at the owner's expense. in these types of vehicles, the active handling & abs is a safety feature, and i can only assume that whenever the warnings are activated these safety functions are no longer functioning as the computer believes that there is a problem with them when there isn't. the warnings do not come on at the time of start up, but only after driving the vehicle for about 5 miles. if there in fact was a problem with these features, a warning would come on at start up. gm has found that the wiring harness becomes stretched from continued use of the telescoping steering column over the years which causes the false warnings. other drivers have reported power steering failure and other problems associated with this. this is a design flaw that could cause drastic problems if the computer falsely disengages these features, especially the abs during driving in the rain or snow. these vehicles rely on these systems for safe operations. once the warning comes on, there is no way to check to see if the active handling feature is on or off, as the computer will not allow the system to be checked. *tr | |||

| Abs tracking control light came on with a failure. it then went out. this happened a couple more times during driving in the next couple of weeks(car not driven that much). october of 2008, abs light came on again and stayed on. took car in to be serviced. was told computer system was bad. tried to locate a used system to save money. was informed by chevrolet service department that could not use a used computer because of a known problem with the computer. had to have replaced and reprogrammed abs trac control module for $1490.80. was told to hang on to receipt because could become recall. *tr | |||

| A message was randomly displayed saying that the active handling system had failed and that service was needed. when this happened, the car's computer would then shut off the active handling system, but when the ignition was turned off and then back on, the active handling system would be active until the next failure. i believe that this failure constitutes a safety problem. after many months of this (i wasn't overly concerned since i don't drive erratically and rarely activate the active handling system), i took the car to a dealer (west chevrolet, alcoa, tn) and was told (1) they have seen this problem before on corvettes and (2) it is due to the wiring harness in the steering column being too short. (this car has a power telescoping steering wheel and memory seats so that every time the driver gets in and out of the car, the steering column automatically moves out and in, evidently tugging on the wiring harness each time.) the dealers technician foreman said that one of signals carried by the harness is the angle of the steering wheel which is used in conjunction with a yaw-rate sensor to determine if the car is spinning out and what corrective action is required to correct this. he also said that due to the too-short harness, the integrity of the harness connector degrades over time causing the intermittent failure of the active handling system. (3) the dealer said that this problem is fixed by extending the harness with a gm part which implies that gm knows that they have a problem and have developed a part to fix it. (4) i asked the dealer what would happen if i did not fix it. i was told that eventually the connector would completely fail resulting in a loss of the power steering. this would then be another safety problem. so i had to have it fixed but it wasn't cheap - $594.68. *tr | |||
