AIR BAGS
Dash warning light indicates check airbags. (About a year ago). Upon using a code reader it states that the wrong airbags are installed and needs to be replaced. The airbags had been replaced in 2007 by GMC after a serious accident as a program\loaner. I purchased the repaired vehicle from Southern Chevrolet in December of 2007 from their used car lot. I do not know why it has gone unnoticed for all these years.

AIR BAGS
The driver side airbag did not deploy when I got into a wreck. I feel the airbags could have helped me from hitting the steering wheel and hurting my ribs. I feel that it could have been less painful to have the airbag deploy. I thought the airbags were in working order.

ELECTRICAL SYSTEM, ENGINE
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.

ELECTRICAL SYSTEM
There is an electrical connector behind the right side, kick panel that overloads and chars the plastic housing. The connector is for the rear defroster grid, but it cannot handle the amperage that the grid carries. It overloads and is a fire hazard that can could start a fire in the passenger compartment. It is a very common problem on ninth generation Chevrolet Impalas, to the point there are multiple YouTube videos, offering shade tree repair advice that bypass the connector with a jumper wire. I’m including a link to one such a video. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE, FUEL/PROPULSION SYSTEM, VEHICLE SPEED CONTROL
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.

ENGINE
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.
