Porsche CAYENNE TURBO problems and owner complaints

THE "EMISSION CONTROL, CHECK ENGINE" LIGHT CAME ON IMMEDIATELY AFTER THIS OCCURRED. THE INCIDENT CAUSED WHIPLASH BECAUSE THE CAR JOLTED SO SUDDENLY.

LATE 2010 TO EARLY 2012 PORSCHE CAYENNE VEHICLES WITH V8 ENGINES HAVE A MANUFACTURING DEFECT WITH BOLTS THAT HOLD THE CAMSHAFT ADJUSTERS.

DRIVING ON HIGHWAY WHEN THE CAR DRAMATICALLY LOST POWER AND STALLED, LUCKILY I WAS CLOSE TO AN EXIT AND MANAGED TO GET OFF THE HIGHWAY. HOWEVER THERE WAS AN 18 WHEELER BEHIND ME THAT HAD TO BRAKE HARD TO AVOID HITTING ME. I GOT TO THE BOTTOM OF THE EXIT RAMP AND THE CAR WAS BARELY RUNNING. WAS ABLE TO GET IT BACK TO THE DEALER (WHICH WAS ONLY 1/4 MILE AWAY) THE PROBLEM WAS THE CAMSHAFT ADJUST BOLTS ON BANK #1 SHEARED. THIS IS A KNOWN DEFECTIVE PART AND PROBLEM WITH ALL PORSCHE V8 ENGINES FROM 2011-2012.
