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.

Official recalls
2Jun 23, 2014
This defect can affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. General Motors LLC (GM) is recalling certain model year 2005-2009 Buick LaCrosse, 2006-2011 Buick Lucerne, 2000-2005 Cadillac DeVille, 2006-2011 Cadillac DTS, 2006-2014 Chevrolet Impala, and 2006-2007 Chevrolet Monte Carlo vehicles. In the affected vehicles, the weight on the key ring and road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.
Consequence & remedy
Consequence: If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury. Additionally, a key knocked out of the run position will cause loss of engine power, power steering, and power braking, increasing the risk of a vehicle crash.
Remedy: GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 23, 2014. Owners may contact General Motors customer service at 1-800-521-7300 (Buick), 1-800-458-8006 (Cadillac), and 1-800-222-1020 (Chevrolet). GM's number for this recall is 14299.
