I TOOK MY CAR TO HALL IN BROOKFIELD WI TO FIX A RECALL ISSUE. THE DEALER TOLD ME THEY FIXED THE RECALL ISSUE BUT NOTICED ANOTHER PROBLEM THAT REQUIRES THE REPLACEMENT OF THE DIFFERENTIAL BUSHINGS BECAUSE THEY WERE TORN. THEY CHARGED ME OVER $500 FOR THIS ISSUE AND I BELIEVE THE ISSUE WAS EXASPERATED BY THE RECALL ISSUE AND I AM NOT SURE WHY I HAD TO PAY. I HONESTLY BELIEVE IT WAS A WAY FOR THE DEALER TO CHARGE ME FOR THE RECALL WORK BECAUSE IT WAS SUPPOSED TO BE FREE. I AM ATTACHING RECEIPTS FOR THE WORK HALL DID TO THIS COMPLAINT. NOW MY CAR IS HAVING ISSUES WITH PROPERLY ACCELERATING AND IS VERY LOUD.
