I WAS DRIVING AT APPROXIMATELY 55MPH ON A HIGHWAY WHEN THE VEHICLE GAVE A WARNING OF 'ENGINE POWER IS REDUCED'. MY CAR QUICKLY DROPPED TO 20MPH AND I WAS UNABLE ACCELERATE. THIS HAPPENED WHILE THERE WAS ANOTHER VEHICLE BEHIND ME AND I WAS SCARED I WAS GOING TO BE REAR ENDED. I PUT MY HAZARD LIGHTS ON AND PARKED MY VEHICLE. I SHUT THE VEHICLE OFF AND TURNED IT BACK ON WHICH ALLOWED ME TO OPERATE THE VEHICLE AGAIN BUT ONLY AT A CAPACITY OF 40MPH. I HAD THE VEHICLE REPAIRED LATER THAT DAY IT NEEDED SOMETHING WITH AN ELECTRONIC THROTTLE CONTROL AND PEDAL SENSOR REPLACED. I ALSO LEARNED THAT THIS IS AN ISSUE THAT GM IS WELL AWARE OF AND FEEL THAT THEY NEED TO RECALL VEHICLES AFFECTED BY THIS ISSUE. THERE'S NO REASON A VEHICLE SHOULD BE DROPPING TO 20 MPH UNEXPECTEDLY ON A HIGHWAY.
WHILE DRIVING MY ENGINE AND TRACTION LIGHT CAME ON AND A SENSOR POPPED UP THAT READ 'ENGINE POWER IS REDUCED'. I WAS DRIVING DOWN THE HIGHWAY AND MY SPEED WAS REDUCED. I CAN'T AND COULD NOT SPEED UP.
