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.”

“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.”

FIRST TRANS WAS INSTALLED IN 2016 OCTOBER”
