A FEW YRS AGO I BOUGHT A NEW CAR AT LOCAL DEALERSHIP AND WAS GIVEN A "FREE OIL CHANGE FOR LIFE" DEAL INCLUDED WITH THE PURCHASE, EVERYTIME I TOOK THE CAR FOR OIL CHANGE THEIR SERVICE DEPARTMENT ALWAYS PUSHED FOR SERVICE/MAINTENANCE THE VEHICLE DOES NOT NEED AND WANTED TO CHARGE ME AN ARM AND A LEG FOR UNNECESARY REPAIRS... IN ONE INSTANCE THEY EVEN LOOSEN SCREWS ON THE ENGINE TO CREATE OIL LEAKS MY CAR HAD ONLY 8, 000 MILES ! ALSO WATCH OUT FOR "CHECK ENGINE LIGHT" THERE IS A LOT OF FRAUD ON THAT. AFTER THIS SOUR EXPERIENCE I WILL NEVER BUY A CHEVY CAR INSTEAD I AM READY TO GET ME A NEW CHRYSLER... OR A NEW ELECTRIC CAR, I HOPE TO GET A DEAL OF HONESTY...!
I have taken my 2009 Tahoe for the same complaint of a howling sound coming from the drivers side window and twice I have told that nothing is wrong.
