NHTSA Complaint #10427791 — 2009 CHEVROLET IMPALA

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
