This problem has been getting progressively worst. The car has been having troubles turning over on cold starts, and has experienced a loss of propulsion and stall going up hill including a loss of brakes since I bought it a year ago. On 9/6/2014 the car was started and was idling high (approximately 4000rpm), check engine light was on, speed control light was on, incline alert light on, sport mode light was on and check emissions system light was on. Had to move the car out of the garage and it barely made it up the incline in the underground garage as it was not responding to the accelerator, called for a tow which never arrived and tried to restart out of frustration all lights were off and car I made it to the dealer which was not far away. Have already had the dealer inspect the car once to get to the bottom of the problem and they reported their diagnostics showed nothing was wrong and that car electrical\computer problems cannot be fixed until they break completely (or someone is hurt or injured perhaps). There was one more report similar to this on carcomplaints. Com that occurred at high speed. Seems to me that car is not safe at this point.
