The "vsc off" and vsc skid lights came on and has remained on to the present date. when the lights came on all vsc functions stopped. vehicle was taken to the dealership. repair was not under any warranty. an estimate of approximately $2200 was given to replace the vehicles ecu. no repair was made. occasionally the vehicle would lose power under moderate acceleration for a brief period (usually less than 2 seconds) as if something has cut power 20-30%. i suspect it was the vsc system trying to cut on or engage. this has not happened for some time. vehicle now has 178000 miles. *tt
