2007 Chevrolet Impala engine and engine cooling problems

“TL* THE CONTACT OWNS A 2007 CHEVROLET IMPALA. WHILE DRIVING 35 MPH, THE CONTACT NOTICED SMOKE UNDER THE HOOD. THE CONTACT TURNED THE VEHICLE OFF AND ALLOWED IT TO COOL DOWN. AFTER, APPROXIMATELY 5 TO 10 MINUTES, THE VEHICLE WAS RESTARTED AND OPERATED NORMALLY. THE CONTACT NOTICED THAT THE ENGINE WARNING INDICATOR WAS ILLUMINATED AND THE VEHICLE WAS LEAKING COOLANT AND OIL. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE INTAKE MANIFOLD GASKETS FAILED. THE VEHICLE WAS NOT REPAIRED. THE DEALER WAS NOT CONTACTED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND INFORMED THE CONTACT THAT THE VIN WAS NOT INCLUDED IN ANY RECALLS. THE FAILURE MILEAGE WAS 200,000.”

“EVERY TIME I TURN THE HEAT FROM THE AIR CONDITIONING, AND VICE VERSA, IT MAKES A LOUD CLICK CLACKING SOUND THAT LASTS FOR ABOUT A MINUTE OR TWO AND IS LOUD ENOUGH TO BE HEARD INSIDE AND OUTSIDE OF THE CAR. VERY EMBARRASSING. OTHERS THAT OWN A SIMILAR VEHICLE HAVE HAD THE SAME ISSUES. *TR”

“I PURCHASED MY VEHICLE IN LATE MARCH 2010. SHORTLY THEREAFTER, MY CAR BEGAN TO LOSE POWER. I HAD AT LEAST 3 INCIDENCES THAT I CAN REMEMBER, 1 OF WHICH WAS GOING DOWN THE INTERSTATE AND THE CAR COMPLETELY DIED. FRIGHTENED, I WAS ABLE TO GET THE CAR TO THE SHOULDER AND PUT THE VEHICLE IN PARK. MY FIRST REACTION WAS TO ATTEMPT TO RESTART THE VEHICLE. IT STARTED UP RIGHT AWAY AND I WAS ABLE TO MAKE IT SAFELY HOME. THE OTHER INCIDENTS WERE ON MAIN ROADS IN TOWN. THE CAR DID THE SAME THING. AFTER THE INTERSTATE ORDEAL, I IMMEDIATELY TOOK THE CAR TO BEATY CHEVROLET IN KNOXVILLE, TN. THEY STATED THAT THE IGNITION WENT OUT AND NEEDED TO BE REPLACED. NOW, I UNDERSTAND THAT OTHER GM OWNERS HAVE HAD THIS SAME ISSUE. A RECALL DEFINITELY NEEDS TO BE ISSUED SO NO MORE PEOPLE ARE PUT IN HARM'S WAY. THIS IS A KNOWN ISSUE ACCORDING TO AN OPERATOR NAMED [XXX] AT GM WHEN I CALLED A FEW MINUTES AGO TO INQUIRE ABOUT THE CURRENT RECALL REGARDING THE KEY/FOB TURNING ISSUE. SHE STATED THAT THE RECALL HAD NOT YET BEEN ISSUED REGARDING MY ISSUE AND THAT I NEEDED TO FILE A COMPLAINT WITH YOUR DEPARTMENT. I BELIEVE THAT THIS KNOWN ISSUE IS BEING SWEPT UNDER THE RUG BY THE BIG CORPORATION…”

“WHILE DRIVING MY 07' CHEVY IMPALA THE TEMPERATURE GAUGE ARM OFTEN WILL DROP TO 'C' AS IF THE ENGINE TEMPERATURE IS COLD, THEN THE DRIVERS INFORMATION DISPLAY PANEL WILL DISPLAY A MESSAGE "ENGINE HOT TURN OFF A/C". I'VE HAD THE THERMOSTAT REPLACED, RADIATOR COOLANT DRAINED AND REPLACED, HOPING TO FIX THIS PROBLEM, BUT I'M STILL DEALING WITH IT. AFTER DOING SOME RESEARCH I'M FINDING THAT THERE HAS BEEN OTHER CHEVY VEHICLE OWNERS DEALING WITH THIS SAME ISSUE, WHICH IS MOST LIKELY A BAD 'ENGINE COOLANT TEMPERATURE SENSOR (ECT). *TR”

“INTERMITTENT PROBLEMS WITH "SERVICE TRACTION CONTROL" AND "ENGINE POWER REDUCED". MY IMPALA IS STARTING TO RUMBLE AND JOSTLE WHEN THESE WARNINGS APPEAR. HOWEVER, I CAN'T FIGURE OUT THE REASON. *TR”

“WHILE I WAS DRIVING AN ERROR MESSAGE APPEARED ON THE PANEL "ENGINE POWER REDUCED". THE CAR IMMEDIATELY SLOWED DOWN AS IF THE ENGINE HAD CUT-OFF COMPLETELY. IT DID NOT AND I WAS ABLE TO DRIVE TO THE SIDE OF THE ROAD AT ABOUT 10 MPH. LUCKILY IT WAS LATE AT NIGHT, THE FEW CARS THAT WERE DRIVING NEAR ME WERE ABLE TO CHANGE LANES BEFORE A COLLISION OCCURRED. *TR”
