THERE IS A HORRIBLE CLUNKING NOISE COMING FROM FRONT WHEN DRIVING OR TURNING (POSSIBLE PASSENGER SIDE). IT DOESN'T MATTER WHAT YOUR SPEED IS. IT SOUNDS LIKE IT MAY BE THE SUSPENSION OR STRUTS AND IT'S SO BAD THAT IT SOUNDS LIKE MY FRONT END IS FALLING APART. WITH ONLY 2400 MILES IT HAS GOTTEN WORSE AND WORSE. DROPPED IT OFF AT THE DEALERS THIS MORNING AND SERVICE TECH DROVE IT AROUND BUILDING TO COME BACK AND SAY HOW BAD IT SOUNDED. HE SAYS HE HASN'T EVER HEARD THIS NOISE. ALSO, THE REAR, WHEN BREAKING AND ACCELERATING HAS A POPPING NOISE DURING TAKE OFF AND STOPPING. BOTH NOISES ARE GETTING MUCH WORSE TO THE POINT MY HUSBAND SAID THAT I COULD NOT DRIVE IT OUT OF CONCERN FOR SAFETY UNTIL THIS ISSUE IS FIXED. SEEMS CRAZY THAT YOU WOULD ALREADY EXPERIENCE ISSUES LIKE THIS IN A BRAND NEW $50K CAR.
