NHTSA Complaint #10287327 — 2007 CHRYSLER 300

I HAVE A 2007 CHRYSLER 300. I BOUGHT IT USED ON 6/14/08. WITHIN A MONTH THAT I BOUGHT IT, THE CAR STALLED ON ME. A CHRYSLER DEALERSHIP/GARAGE WAS NOT ABLE TO FIND ANYTHING MAJOR EXCEPT THE THROTTLE HAD BUILT IN DEBRIS. EVER SINCE THAT TIME, THE CAR HAS NOT RAN SMOOTHLY. MOST OF THE TIMES, THE CAR FEELS THAT IT LOSES ENERGY/POWER WHEN I START TO DRIVE IT (LIKE WHEN I START THE ENGINE AND START DRIVING). IT ALSO MAKES A NOISE WHEN IT NEEDS TO "SHIFT" TO THE NEXT POWER (IT IS AUTOMATIC TRANSMISSION). IN 6/09-7/09, MY ENGINE LIGHT TURNED ON, WHICH THE GARAGE THAT I HAD TO TAKE IT TO THAT CAN REPAIR ANY TYPE OF EMISSION ISSUES NEEDED TO REPLACE A VALVE AND THEN THE LIGHT DID NOT TURN ON ANYMORE. EVEN AFTER THIS REPAIR, THE CAR CONTINUES TO FEEL LIKE IF IT LOSES POWER. I HAVE REGULAR OIL CHANGES DONE SO I DO NOT KNOW WHAT IS WRONG. I FEEL THAT THERE CAN BE SOME MANUFACTURE DEFECT; HOWEVER, SINCE I HAVE COMPLAINED ABOUT THE ISSUES TO DIFFERENT DEALERSHIPS, THEY SEEM NOT TO FIND ANY PROBLEMS. *TR
