2006 Mercedes Benz SLK350

WHILE DRIVING VEHICLE POWER CAN BE LOST & VEHICLE CAN BE STUCK IN 1ST GEAR OR NO GEAR AT ALL CAUSING BLOCKAGE TO TRAFFIC AND POSSIBLY CAUSING AN ACCIDENT. ONCE YOU TURN CAR OFF IT APPEARS THE CAR RESETS ITSELF AS IF NOTHING EVER HAPPEN. WHEN REPORTED TO DEALERSHIP IT WAS STATED NO CODES POP UP SO I MUST BE HITTING THE SHIFT. NOT KNOWING ANY BETTER & NOT BEING A MECHANIC, WHO AM I TO CONTINUE TO QUESTION THE MERCEDES DEALERSHIP? NO CODE NO ACTION. (1ST REPORTED WITH 8446 MILEAGE NEVER SHOWED A CODE). AT 63,000 MILES THE ENGINE LIGHT FINALLY COMES ON INDICATING A PROBLEM. 63038 FOUND CODE IN SYSTEM FOR SPEED SENSOR NOT READING CORRECTLY. TEST DROVE CAR & STUCK IN LIMP HOME. THE ODD THING IS THE CODE KICKED IN AT 61400 MILES & THE LIGHT CAME ON 2000 MILES LATER. THE EXTENDED WARRANTY COMPANY REFUSED TO FIX MY CAR UNDER THE WARRANTY I PURCHASED DUE THE "DATA FREEZE' SHOWING PROBLEM EXISTED PRIOR TO ME PURCHASING THAT WARRANTY BUT I WAS UNAWARE OF THAT SINCE THE ENGINE LIGHT DIDN'T COME ON AT 61400.
