I started for the first time in early June of having reduced engine power. At this time I get several warrning lights on dashboard. I get engine power is reduced, traction control and engine light. The car goes into limp mode. I replaced the accelerator pedal position sensor after the first event. Since this time I had it happen 4 more times. This situation can be dangerous if a car is behind me and I slow up real quick due to going into limp mode. I try to pull over where I can when this happens. Once I pull over for 10 minutes the car will resume like normal driving with just the engine light on. The next day the engine light usually leaves. It is hard to know when this will occur but it can be a dangerous situation to be in.

HAD ISSUES WITH MY 2007 IMPALA 3.9L STALLING AND REDUCING POWER ON MY WIFE, AND AT TIMES ALMOST LEAVING HER IN OR ON THE ROAD. I HAVE REPLACED THE THROTTLE BODY, THROTTLE PEDDLE ( TWICE ) AND HAD THE CAR FLASHED AT THE LOCAL GM DEALER. NOW THE CAR NOT ONLY READS REDUCED ENGINE POWER IT READ STARTING DISABLED SERVICE THROTTLE AND DIED WHILE SHE WAS DRIVING DOWN A BUSY HIGHWAY DURING RUSH HOUR.. CAUSING HER TO ALMOST BE INVOLVED IN A BAD WRECK. THIS SERIOUSLY NEEDS TO HAVE ATTENTION OF WHOEVER AT GM IS OVER SAFETY, CAUSE THIS ISSUE WILL END UP IN A REALLY BAD SITUATION IF OR WHEN SOMEONE ENDS UP SERIOUSLY HURT OR KILLED. I MEAN YOU REALLY NEED TO PROGRAM THEM TO SLOWLY REDUCE POWER, NOT JUST TELL YOU THEN SHUT OFF COMPLETELY AND HAVE THE DRIVER FIGHT AND PANIC TO GET OFF THE ROAD THROUGH TRAFFIC, WHILE NOT GETTING RUN OVER IN THE PROCESS. BUT IF THERE IS A FIX WE NEED TO KNOW.

I WAS DRIVING MY 2007 CHEVY IMPALA IN MY NEIGHBORHOOD AT 25 MPH, AND WHEN I WAS GETTING READY TO STOP AT A STOP SIGN, THE VEHICLE STARTED TO SHAKE BADLY WITH THE CODE "ENGINE LOSING POWER." LUCKILY, I WAS ABLE TO PULL OVER AND TURN THE CAR OFF. BEING 68 YEARS OLD, I GOT EXTREMELY SCARED. I TURNED THE CAR OFF AND TRIED CALLING 2 OF MY CHILDREN TO HELP ME. NOT BEING ABLE TO GET EITHER ONE OF THEM. I TURNED THE CAR BACK ON, AND PROCEEDED BACK HOME WHICH WAS ONLY ABOUT A HALF MILE FROM MY HOUSE. I CALLED THE PREVIOUS OWNER, AND SHE STATED THAT HAD HAPPENED TO HER ABOUT 6 MONTHS PRIOR. NOW I AM TERRIFIED TO TAKE IT OUT ON THE MAIN HIGHWAY. THE CAR ONLY HAS 70,000 MILES ON IT AND HAD BEEN GARAGED KEPT. SOMEONE PLEASE HELP ME REGARDING WHY THIS MIGHT HAVE HAPPENED. THANK YOU VERY MUCH.

I RECENTLY PURCHASED A 2007 CHEVY IMPALA, 3 WEEKS AFTER PURCHASE WHILE ON THE HIGHWAY, THE CAR SUDDENLY SLOWED DOWN TO A CRAWL, A REDUCED ENGINE LIGHT CAME ON THE DASH, BEING AS WE WERE ON THE HIGHWAY TO SUDDENLY ONLY BEING ABLE TO GO 20MPH WAS VERY FRIGHTENING!! I WAS ABLE TO GET THE CAR TO THE SIDE AND HAD TO HAVE IT TOWED HOME. AFTER SEARCHING THIS ISSUE ONLINE I FOUND THOUSANDS OF COMPLAINTS FROM PEOPLE WITH THE SAME ISSUE WITH THIS SAME CAR. I FIND IT STRANGE THERE WAS NOT A RECALL FOR THIS DUE TO IT BEING A SERIOUS SAFETY ISSUE. AFTER CALLING A CHEVY DEALER, THEY TOLD ME ALL THEY COULD DO IS HOOK IT UP FOR DIAGNOSTIC TESTS BUT IT WOULD COST 175.00 JUST TO DO THAT. THIS VEHICLE IS STILL PARKED AND WE ARE UNABLE TO DRIVE IT AND STILL HAVE NO IDEA WHAT'S WRONG WITH IT. I'M VERY CONCERNED ABOUT DRIVING IT AGAIN FOR FEAR OF THIS HAPPENING AGAIN AND US MAYBE NOT BEING AS LUCKY NEXT TIME!!!! SERIOUS ISSUE WITH THOUSANDS OF COMPLAINTS ONLINE. SIMPLY TYPE IN 'REDUCED ENGINE POWER' MAKE MODEL AND YEAR OF CAR AND MANY PEOPLE HAVE HAD THIS SAME ISSUE!!!!

ENGINE POWER WAS REDUCED WHILE I WAS TRAVELING WITH THE FLOW OF TRAFFIC. I ATTEMPTED TO ACCELERATE BUT CAR STARTED SLOWING DOWN. TOOK THE VEHICLE FOR REPAIR AND REPLACED THE PEDAL POSITION SENSOR WAS REPLACED. I CONTACTED CHEVY DEALERSHIP SERVICE DEPT AND WAS TOLD IT'S A COMMON OCCURRENCE. IMPALAS HAVE A THROTTLE SENSOR INSTEAD OF CABLE. IF THE SENSOR GOES OUT, THE ENGINE POWER IS REDUCED TO PROTECT THE ENGINE INTEGRITY. IN SOME CASES, IT'S REDUCED SIGNIFICANTLY. THE MANUFACTURE NOTED MY CONCERN BUT THE REP WOULD NOT ESCALATE THE MATTER. I WENT ONLINE TO FILE A COMPLAINT AND THERE IS A CHEVY FORUM WITH SIMILAR CONCERNS. GENERAL MOTOR REPS REPLY WITH COMMON RESPONSES TO TAKE THE VEHICLE TO AN AUTHORIZED MECHANIC AND THEIR CONCERN HAS BEEN NOTED. I WAS INFORMED BY REPRESENTATIVE AT 800# FOR MANUFACTURE TO CALL BACK IF IT HAPPENS AGAIN. THANKFULLY I WASN'T GOING AT A HIGHER SPEED IN DALLAS TRAFFIC. NOT SURE IF I WOULD HAVE HAD THE LUXURY OF PULLING OVER.

DIDN'T COME ON THE NEXT DAY BUT WHILE DRIVING IN TOWN, 25-45 MPH, I COULD FEEL A LITTLE OF A PULL TIME TO TIME, SAW THAT THE RPM NEEDLE WOULD JUMP TIME TO TIME. I HAVE ALSO DRIVEN IT ON THE INTERSTATE AND IT IS JUST THE SAME THING.
