2007 Chevrolet Impala Problems

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.

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)

STEERING WHEEL DOES NOT LOCK IN PARK ALARM DOES NOT ENGAGE WHILE PARKED

WHILE DRIVING ON A ROAD MY TIE ROD BROKE CAUSING ME TO LOSE CONTROL OF THE CAR. IT COMPLETELY TURNED AROUND AND LANDED IN SOME TREES.

COMPLAINT: REAR WHEELS LINKAGE WAS DESIGNED SO THAT THE "CAMBER" CANNOT BE ADJUSTED. THE REAR TIRES WEAR AGRESSFULLY ON THE INBOARD EDGES TO A POINT THAT THEY ARE BALD WHILE THE OUTSIDE, WHICH IS VISIBLE, APPEARS TO BE GOOD. THE REAR TIRES BECOME UNSAFE, WITH A WEAR RATE THAT ONLY LAST ABOUT 15,000 MILES. I AM ON MY 5TH SET OF TIRES WITH THE CAR MILEAGE AT 66,000. GM WAS AWARE OF THIS CONDITION IN 2008, BUT THEY ISSUED A TSB (08032A) TO CORRECT ONLY "POLICE CARS" AND DID NOT REPAIR OR LET OTHER PRIVATE CUSTOMERS KNOW ABOUT THIS. MY CAR SERIAL NUMBER IS LISTED UNDER THE ONES ON THE TSB. THIS CONDITION ALSO CREATES A PROBLEM WHEN OPERATING THE CAR IN WET AND SLIPPERY ROADS, SINCE THE REAR TRACKING IS NOT THE SAME AS THE FRONT TIRES. THE CAR TENDS TO WHIP FROM SIDE TO SIDE, AN OPERATORS CAN LOOSE CONTROL. THE PARTS USED BY GM ARE THE SAME AS ON POLICE VEHICLES AS PERSONAL CARS. THEY CLAIMED A PROBLEM, BUT FOR SOME REASON DENY ANY ISSUES ON A PERSONAL CAR! GM DEALERS REFUSE TO EVEN SPLIT THE COST, AND GM WILL NOT CORRECT MY ISSUE.

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.

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.

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.

MY CAR HAS HAD THE POWER STEERING RACK REPLACED 3 TIMES WITHIN A 6 MONTHS TIME FRAME. MY TRANSMISSION WAS REPLACED AND IT SEEMS TO BE SLIPPING AGAIN I HAVE HAD IT REPLACED UNDER A YEAR AGO. I WAS DRIVING WHEN I NOTICED MY CAR SLIPPING FROM 11ST FEAR INTO SECOND. THE DEFROST DOES NOT WORK PROPERLY AND ALL WINDOWS ARE FROZEN MAKING IT UNSAFE TO DRIVE YOUR VEHICLE.

WHEN TURNED CAR ON WIPERS DID NOT WORK, THEY WOULD INTERMITTENTLY COME ON AND WORK BEFORE THEY COMPLETELY STOPPED WORKING AND DO NOT TURN ON AT ALL. CHANGED THE WIPER MOTOR AND THE WIPER SWITCH AND THEY STILL DO NOT WORK. I CURRENTLY DO NOT HAVE WORKING WIPERS ON MY CAR. PEP BOYS WAS UNABLE TO DIAGNOSE A PROBLEM.

The car at lights act like it does not want to go which can cause a wreck
