2009 Chevrolet Impala

I WAS DRIVING ON THE HWY WHEN THE MESSAGE APPEAR ON THE BOAR "ENGINE POWER REDUCE " I WAS SCARED BECAUSE I HAVE NEVER HAD THAT PROBLEM. I WHEN ONLINE AND SAW THAT PEOPLE WERE HAVING THE SAME PROBLEM. IT WAS WEIRD BECAUSE THEY ALL SEEN TO BE IN THE SAME MONTH LIKE IF IT WAS PROGRAM TO HAPPEN. SO I WANT AN EXPLANATION ON WHAT'S GOING ON WITH MY CAR? WHAT'S THE MESSAGE ABOUT? DO I HAVE TO CHANGE THE MOTOR ? I JUST DON'T KNOW WHAT TO DO ANYMORE THIS CAR HAS A LOT OF PROBLEM I JUST WANT SOME ANSWERS . THANKS FOR READING. *TR

HAD THE CAR IN FOR NORMAL INSPECTION AND WAS INFORMED I HAD UNEVEN REAR TIRE WEAR ON REAR TIRES.. THEY HAD TO GRIND THE REAR SPINDLE TO GET PROPER FOUR WHEEL ALIGNMENT 2011. 12 MONTHS LATE 2012 WAS INFORMED IN 2012 INSPECTION HAD TO REPLACE ALL FOUR TIRE AND FOUR WHEEL ALIGNMENT AND HAVE TWO REAR SPINDLE BOLT TO COMPLETE JOB. THERE WAS NEVER A MENTION OF THE CLASS ACTION LAWSUIT OR IF THE DEALER WOULD STAND HIND THE PRODUCT AND WARRANTY THE WORK DONE. *TR

I NOTICED SOME TIME BACK THAT WHEN APPLYING THE BRAKES THAT I WOULD GET A ROUGH VIBRATION, SUCH AS WITH BAD ROTORS. I TOOK THE CAR TO THE DEALER THAT I PURCHASED IT AT AND THEY LOOKED IT OVER AND STATED THAT EVERYTHING WAS FINE. SINCE THEN EVERYTIME I HIT THE BRAKES THE VIBRATIONS HAVE ONLY GOTTEN WORSE, IT'S TO THE POINT NOW THAT IT VIOLENTLY SHAKES THE ENTIRE CAR AND FEELS AS IF IT'S GOING TO JERK THE STEERING WHEEL RIGHT OUT OF MY HANDS. SO I MADE ANOTHER APPOINTMENT FOR THIS ISSUE AND A NEW ONE; SOMETIMES MY DASH LIGHTS WILL FLICKER AND IT WILL TELL ME IT'S 102 OUTSIDE WHEN IT'S ONLY 70 AND AUTOMATIC TIRE PRESSURE SENSOR IS WAY, WAY OFF. I HAVE ALSO NOTICED RECENTLY THAT MY FRONT TIRES HAVE BECOME EXCESSIVELY WORN ON THE OUTER EDGES TO WHERE THERE IS ONLY TREAD IN THE CENTER AND THIS SHOULDN'T BE A PROBLEM WITH ONLY 21,500 MILES ON THE VEHICLE; I SHOULD HAVE BEEN ABLE TO GET ABOUT TWICE THAT OUT OF THE FACTORY TIRES. AT MY LAST APPOINTMENT THEY HAVE STILL SAID THERE IS NO NOTABLE PROBLEMS WITH MY IMPALA. *TT

FRONT TIRES HAVE EXCESSIVE WEAR ON THE INSIDE AND OUTSIDE OF THE TIRES ONLY. ORIGINAL GOODYEAR INTEGRITY TIRES ARE STILL ON THE CAR. REAR TIRES ARE FINE AND LOOK "NORMAL". AFTER READING ABOUT OTHER ISSUES LIKE THIS IT MAKES ME BELIEVE THERE IS SOME SORT OF ISSUE WITH THE ALIGNMENT OF THE CAR. I AM CONCERNED ABOUT THE SAFETY OF MY VEHICLE. IT WILL NOT PASS INSPECTION AS IT IS. I WILL HAVE TO REPLACE THE TIRES BECAUSE THERE IS NO TREAD ON THEM EXCEPT FOR IN THE MIDDLE OF THE TIRES WHICH IS REALLY ODD. NOT SURE HOW MANY PEOPLE HAVE THIS PROBLEM. THIS IS MY SECOND IMPALA AND I'VE NEVER HAD THESE ISSUES BEFORE. I HAVEN'T CONTACTED THE DEALERSHIP YET ABOUT THIS. I WILL SEE WHAT THEY HAVE TO SAY. *TR

THIS IS A COPY OF A COMPLAIN THAT HAS BEEN SENT TO THE CHEVROLET DIV. OF GENERAL MOTORS. CHEVROLET CUSTOMER ASSISTANCE CENTER PO BOX 33170 DETROIT, MI 48232-5170 [XXX] SEPT. 23, 2010 RE: WARRANTY DECEPTION ( VEHICLE 2009 IMPALA) THIS VEHICLE IS STILL UNDER WARRANTY WITH ODOMETER READING OF 27,000 MILES. A STUD BROKE OFF THE RT REAR WHEEL AND THE LARRY GREEN SERVICE DEPT.IN COTTONWOOD, ARIZONA REFUSED TO REPAIR IT UNDER THE BUMPER TO BUMPER WARRANTY. THEY CLAIMED IT WAS SHEARED OFF BY WHOMEVER ROTATED THE TIRES LAST. MY CLAIM WAS THAT THE TIRES WERE NEVER ROTATED AND THE STUD BROKE. I ALSO CLAIM THAT IT DOESN'T MAKE ANY DIFFERENCE BECAUSE NO MATTER WHEN AND IF THE TIRES WERE ROTATED AT SOME TIME IN THE FUTURE A STUD MAY BREAK BY ROAD IMPACT. IF IT CAN BE PROVEN THAT THE STUD IS DEFECTIVE IT MAY RESULT IN A MASSIVE RECALL. HOW MUCH TORQUE IS REQUIRED TO TWIST OFF A STUD WITH A STANDARD WRENCH? THEY ALSO CLAIM THAT THE STUD DIDN'T COME FROM THE FACTORY DEFECTIVE. THAT IS AN ASSUMPTION. ( OF COURSE WITHOUT TESTING THE STUD IT IS UNKNOWN.) WITH THAT LOGIC ANYTHING THAT BREAKS CAN BE EXCUSED AS AN EXISTING CAUSE. THE 3 YEAR WARRANTY IS DECEPTIVE. IF AUTOMOBILE PARTS NEVER BREAK THE JUNK YARDS WOULD BE EMPTY! GENERAL MOTORS SHOULD INVESTIGATE THIS BEFORE THERE IS A FATALITY IN THE EVENT OF AN ACCIDENT OR NOT! WHAT LARRY GREEN HAS LOST IS THE GOOD WILL OF A KOREAN VET AND PERHAPS MANY OTHER VETS THAT MAY HEAR OF THIS. I HAVE SPENT MANY HOURS IN KOREA REMOVING BUSTED STUDS THAT, HOPEFULLY, ALSO DID NOT COME FROM THE GM FACTORY DEFECTIVE.
