THE VEHICLE SEEMS TO WANT TO CUT OFF WHILE AT A TRAFFIC LIGHT! I SIMPLY DO NOT UNDERSTAND WHY THE ENGINE SEEMS TO BE SO LOUD. I HAD BOTH SHOCKS AND STRUTS REPLACED AFTER PURCHASING THIS VEHICLE. THE ENTIRE FRAME SEEMS TO NOSE DIVE OR "WANDER" WHILE I AM DRIVING ON THE HIGHWAY, TOTALLY UNCOMFORTABLE FEELING. TIRES ARE BASICALLY NEW I JUST DON'T KNOW WHAT SEEMS TO BE GOING ON WITH THIS CAR!
