SINCE I HAVE HAD MY IMPALA I HAVE HAD SEVERAL PROBLEMS WITH THE CA. THE FIRST PROBLEM THAT I NOTICED WAS THAT MY WINDSHIELD WIPER FLUID STOP COMING OUT AFTER ON HAVING THE CAR A FEW MONTHS, I LATER FOUND OUT THAT THE MOTOR HAD GONE OUT. ANOTHER PROBLEM THAT IM HAVING IS THAT THE CHECK TIRE SERVICE LIGHT CONTINUES TO COME ON EVEN AFTER, TIRES HAVE BEEN FILLED AND REPLACED, I HAVE ALSO NOTICED THAT ON OCCASIONS MANY OF THE OTHER SERVICE LIGHTS COME ON LIKE CHECK AIRBAGS, AND BRAKES EVEN AFTER CAR HAS BEEN SERVICED. MY BIGGEST ISSUE IS THAT MY TRANSMISSION FLUID HAS BEGUN TO LEAK OUT MY CAR AND NO ONE NOT EVEN THE DEALERSHIP CAN FIGURE OUT WHERE OR WHY ITS LEAKING. THIS CAUSES THE CAR TO HESITATE AND JERK UPON ACCELERATION. READING A LOT OF THE FORUMS OUT I'M NOT THE ONLY PERSON HAVING THESE PROBLEMS AND I THINK THAT AN INVESTIGATION SHOULD BE DONE ON THE IMPALA. *TR

TL* THE CONTACT OWNS A 2007 CHEVROLET IMPALA. THE CONTACT STATED THAT WHILE DRIVING 65 MPH, THE ENGINE REDUCE POWER WARNING LIGHT ILLUMINATED AS THE VEHICLE STALLED.

THE VEHICLE WAS TAKEN TO THE DEALER WHO WAS UNABLE TO DIAGNOSE THE FAILURE. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED.

EXITING THE DARTMOUTH STREET PARKING GARAGE (UNDERGROUND) ON DARTMOUTH ST. BOSTON, MA. EXIT RAMP IS A MODERATE INCLINE. AS I APPROACHED THE GARAGE ATTENDANT BOOTH TO PAY PARKING FEE, I LET OFF THE ACCELERATOR LETTING THE CAR COAST TO A STOP WHILE I RETRIEVED THE PARKING TIME/DATE RECEIPT. WHEN I LOCATED THE RECEIPT (ABOUT 5 SECONDS) FROM THE CENTER CONSOLE I LOOKED UP TO FIND THE CAR WAS ROLLING BACKWARDS DOWN THE RAMP TOWARD A CONCRETE WALL (BY THIS TIME) APPROXIMATELY 15 MPH. NOTE: I AM A 50 YEAR OLD, (MALE) RETIRED POLICE OFFICE AND WAS TRAINED IN RADAR SPEED ENFORCEMENT INCLUDING CERTIFIED IN SPEED ESTIMATION AND I AM ALSO "EVOC" (EMERGENCY VEHICLE OPERATOR COURSE) TRAINED. I WAS ABLE TO STOP THE CAR BEFORE HITTING THE WALL, ANOTHER VEHICLE, OR ANY PEDESTRIANS. I FEEL A TRAGEDY COULD HAVE OCCURRED HAD SOMEONE BEEN WALKING IN THE GARAGE. THE CAR SEEMS TO HAVE NO ABILITY TO "HILL HOLD" WHEN IN "DRIVE" AT IDLE. I WAS SHOCKED AT HOW FAST THE AUTO ACCELERATED BACKWARD. I HAVE PERSONALLY DRIVEN APPROXIMATELY 750,000+ MILES WITHOUT AN AT FAULT COLLISION. THE CAR SEEMS TO DO THIS WHENEVER ON AN INCLINE AND ON A FEW OTHER OCCASIONS HAD OCCURRED IN PARKING LOTS ROLLING (FORWARD AS WELL AS BACKWARD) AS SOON AS SHIFTED OUT OF "PARK" IN THE FRACTION OF A SECOND TIME THAT IT TAKES TO MOVE MY DRIVING FOOT (RIGHT) FROM BRAKE (DUE TO PARK INTERLOCK) TO ACCELERATOR. NOTE: THIS AUTO IS A 2007 CHEVROLET IMPALA SS WITH 5.3L V8 ENGINE AND FOUR SPEED AUTOMATIC TRANSMISSION. MY PRIMARY CONCERN IS THAT IMPALAS ARE GENERALLY DRIVEN BY ELDERLY DRIVERS WITH SLOWER REFLEXES THAN MYSELF. I HAVE FURTHER FOUND NUMEROUS ONLINE FORUM DISCUSSIONS OF THIS ISSUE BY OWNERS OF ALL ENGINE EQUIPPED CHEVROLET IMPALAS. *TR

REAR WHEELS CANTER ARE OUT OF SPEC AND CANNOT BE SET PROPERLY RESULTING IN WHEEL WEAR AND TIRE REPLACEMENT 5000 MILES INTO NEW TIRES. ALSO THE WEAR IS ON THE INSIDE OF THE WHEEL SO THERE AREN'T ANY VISUAL INDICATIONS OF WEARING UNTIL THE TIRES BLEW OUT. I HAVE SMALL CHILDREN THAT CANNOT BE PUT IN THAT TYPE OF DANGER. *TR

THE GAS GAUGE NEEDLE AND DIGITAL READOUT ARE OFF. GOING 55 MPH AND THE CAR JUST DIED IN TRAFFIC. GAUGE READ 1/4 MILE AND DIGITAL READOUT SHOWED 70 MILES LEFT. TOPPED OFF GAS IN TANK TO TRY AND MONITOR AND RAN OUT OF FUEL AGAIN GOING BY NEEDLE AND DIGITAL READOUT. 74 MILES LEFT, JUST SHY OF 1/4 TANK ON NEEDLE. NOW USING TRIP MILE FEATURE TO NOT BE FOOLED BY GAUGE AND NEEDLE. "HALF TANK" RULE IS NOW BEING USED. *TR

I BOUGHT MY CAR USED WITH 40,000 MILE ON IT. THE TIRES WERE PERFECT WHEN I BOUGHT IT. 9,000 MILES LATER, MY FRONT TIRES KEPT GOING FLAT. I LOOKED AT THEM AND THE ENTIRE INSIDE OF THE TIRES WERE WORN THROUGH. I TOOK IT TO THE LOCAL TIRE SHOP AND THEY TOLD ME THE TIRES WORE LIKE THAT DUE TO A BAD ALIGNMENT. MY STEERING SEEMED FINE. THE MANAGER OF THE SHOP CAME OUT TO TELL ME THAT MANY OF HIS CUSTOMERS WITH IMPALAS HAVE SIMILAR ISSUES. A EXTRA LONG FACTORY INSTALLED CAMBER BOLT CAUSES THE VEHICLES TO BECOME UN ALIGNED, AND CAUSES EXCESSIVE WEAR ON THE TIRES. *TR
