MY SEAT SENSOR IN MY CAR FAILED AT 7000 MILES OF USE. I HAVE A LOW MILEAGE MERCEDES AND IT WILL COST ALMOST 875 DOLLARS TO REPLACE. THIS SENSOR DISABLES THE PASSENGER AIR BAG IN CASE OF A BABY SEAT. I HAVE NEVER USED A BABY SEAT IN MY CAR AND IT IS NOW IN THE LOCKED (OFF) POSITION MAKING THE CAR EXTREMELY DANGEROUS FOR THE PASSENGER. FORTUNATELY I RARELY HAVE A PASSENGER BUT I WANT SOMEONE TO INVESTIGATE HOW OFTEN THIS SENSOR FAILS. WHEN THE CAR WAS NEW IT WAS TOUTED AS A SUPER SAFE CAR IN CASE YOU HAVE A BABY. NOW THAT IT IS IN LOCKED OFF POSITION IT IS A SUPER UNSAFE CARE FOR AN ADULT. [XXX] [XXX] BY THE WAY THERE ARE ALSO OTHER DEFECTS IN THIS PARTICULAR CAR. THE AIR COMPRESSOR EXPLODED AT ABOUT 4K MILES. THAT WAS REPLACED BY THE DEALER AT HIS COST. THE BATTERY DIED AT LESS THAN 3 YEARS BUT I HAD IT REPLACED BY THE DEALER AT 4 YEARS ALSO. AND... NOW THEY SAY THERE IS A POSSIBLE PROBLEM WITH MY FUEL TANK VERSUS A MALFUNCTIONING VALVE. THIS IS A LOT OF PROBLEMS FOR A 7347 MILEAGE CAR.

I PURCHASED THE CAR WITH 1,000 MILES ON IT, I WAS THE 3RD OWNER. 1ST OWNER WAS DEALER IN NJ, 2-ND OWNER WAS MY FATHER. THE PROBLEM STARTED AROUND 15,000 MILES AND HAS CONTINUED. THE PROBLEM IS WITH THE REAR BRAKE3 LIGHT ASSEMBLY. I HAVE BEEN TOLD THAT THIS IS A "KNOWN DEFECT" THAT HAS NOT BEEN RECALLED WITH THE SLK MODEL THAT MERCEDES MANUFACTURES. I HAVE BEEN TOLD THE TAIL LIGHT ASSEMBLY DOES NOT HAVE A WAY TO COOL OFF AND GETS TOO HOT AND BURNS UP CAUSING THE BRAKE LIGHTS TO LOOSE CONNECTION AND THEY FAIL. 4 DIFFERENT MECHANICS HAVE ALL TOLD ME THE SAME STORY. I WAS TOLD THAT I COULD KEEP REPLACING THE PART AND THE SAME THING WOULD HAPPEN AGAIN AND AGAIN AND I WOULD NOT BE ABLE TO CORRECT THIS DEFAULT BECAUSE OF THE DESIGN OF THE MODEL OF THIS MERCEDES. I AM AFRAID THAT I AND MY SON WHICH IS 2 WILL BE IN A SERIOUS ACCIDENT MAYBE EVEN FATEL IF SOMETHING IS NOT DONE, I HAVE GONE TO THE DEALERSHIP LOOKING FOR HELP, THEY WILL NOT HELP ME, THEY TOLD ME TO GO TO MERCEDES, THEY WILL NOT HELP ME. I HAVE BEEN SHOW THE PART THAT GETS TOO HOT AND LOOSES ITS CONNECTION. I HAVE THEM WITH ME FOR PROOF OF WHAT I AM SAYING IS FACTUAL AND MERCEDES IS NEGLECTING THIS ISSUE. I ASSUME THEY DON'T WANT TO BE BOTHERED WITH AN EXPENSIVE RECALL. PLEASE HELP US.*AK
