NHTSA Complaint #10520978 — 2011 CHEVROLET EQUINOX

I WAS DRIVING DOWN A MAJOR INTERSTATE DECREASING MY SPEED FROM 55 TO 40. THE CAR CONTINUED TO DECREASE THE SPEED WITHOUT INTERVENTION FROM ME. I APPLIED GAS TO INCREASE THE SPEED AND THE CAR WOULD NOT GO ABOVE 5 MILES ALTHOUGH THE GAS PEDAL WAS PUSHED TO THE FLOOR. I COASTED TO THE LEFT SIDE OF ROAD WAITED TO CLEAR TRAFFIC AND CHANGED SEVERAL LANES GOING 5 MILES AN HOUR. IT WAS FRIGHTENING. I HAD THE CAR TOWED AND AFTER THE DEALERSHIP PERFORMED THEIR ANALYSIS STATED IT NEEDED AN OIL CHANGE. YOU GOT TO BE KIDDING!! HOW STUPID DOES THIS DEALERSHIP THINK I AM - JUST BRUSHING OFF THIS PROBLEM. THIS IS THE SECOND TIME THIS HAS HAPPENED TO ME. THE ENGINE RUNS VERY ROUGH AND LOUD. TODAY, IN ANOTHER LOCATION THERE WAS A TERRIBLE ACCIDENT WITH A CAR AND 2 TRACTOR TRAILERS. THE NEWS PERSON STATED THE CAR JUST BEGAN TO SLOW DOWN WITHOUT ANY APPARENT CAUSE AND STOPPED. THIS SOUNDS WHAT HAPPENED TO ME. CHEVY NEEDS TO EXPLAIN AND FIX THE PROBLEM. I DON'T TRUST THIS VEHICLE. *TR
