WHEN I FIRST PURCHASED THE CAR IT HAD A CRACKED HEAD AND MANY OTHER MINOR PROBLEMS. I REPEATEDLY BROUGHT IT BACK TO THE DEALERSHIP AND THEY TOLD ME THAT THERE WAS NOTHING WRONG WITH THE CAR. I AM STILL EXPERIENCING A "CHECK GAS CAP" WARNING AND I HEAR A CLICKING NOISE COMING FROM THE REAR RIGHT SIDE EVERYTIME I APPLY THE BRAKES. ALSO I HEAR A RATTLING NOISE EVERYTIME I HIT ANY SIZE OF BUMP. *JB
