1st session of day which was going well and boom esc+tc failure. Had to drag car in under limo mode. Shut car down and it wouldn't start up again. Had mechanic look at since he was at track and the computer showed camshaft issue. Car was done and had to flat bed to dealer. Geez I already had a camshaft related failure already on this car and this was the 3rd time I had my car towed from Cota bc of a failure. This car is supposed to be a track car, but geez,I rarely get to drive it these days!
