2007 Mercedes-Benz S550 Engine Problems

I brought a car from a car dealer in tampa Florida and when i got the car i noticed that the car would not pickup speed after pressing the gas pedal and it was asking me to turn off the engine or it will fail . also when i tried to put in coolant. I seen a milky substance that was coming out of the hoses and in the overflow tank of the coolant reservoir which indicates issues with the heads or head gasket . also the title i got says salvaged which i asked if there was anything wrong with the car and the car dealer told me no . never disclosing that the car has been salvaged . there are other issues with the car that i forget because of so many issues with the car that i cant keep up with and i want to return the car to the car dealer and get my money back and have tried but they refuse to make good on the sale

WORN TIMING SPROCKET AND BALANCE SHAFT WAS DEFECTIVE WHEN I PURCHASE THE VEHICLE IN 2011. MERCEDES BENZ KNEW ABOUT THIS DEFECTIVE PART AND DID NOT INFORM ME. THE VEHICLE HAD 46000 MILES ON IT AT THE TIME. IF I WAS INFORM ABOUT THIS PROBLEM I WOULDN'T HAVE BOUGHT IT. I BELIEVE THIS IS A VIOLATION OF THE CONSUMER PROTECTION ACT. *TR

MY LAST TWO VEHICLES HAVE BEEN A 2007 MERCEDES S550. MY FIRST ONE OPERATED WELL UNTIL THE LAST 6-MONTHS THAT I HAD IT. DURING THAT TIME, I HAD SIX VISITS AND $5000+ IN REPAIRS, BEFORE A FREAK FLOOD TOTALED THE CAR. I USED THE INSURANCE MONEY AND PURCHASED A SECOND CAR, IDENTICAL TO THE FIRST. I HAVE NOT EVEN MADE THE FIRST PAYMENT, AND THE CAR HAS BEEN DIAGNOSED WITH A GASKET LEAK BETWEEN THE UPPER / LOWER INTAKE MANIFOLD. THIS IS A MOLDED GASKET AND IS NOT FIELD REPLACEABLE. THE ENTIRE MANIFOLD MUST BE REPLACED AT $2000. IN MY RESEARCH, IT HAS BEEN DISCOVERED THAT THIS HAS BEEN A KNOWN ISSUE WITH MERCEDES, BUT THEY REFUSE TO ISSUE A RECALL TO CORRECT THE PROBLEM. INSTEAD, THEY ALLOW THE WARRANTY TO EXPIRE AND ALLOW THE CONSUMER TO PAY FOR THE BILL. I HAVE CONTACTED MERCEDES BENZ USA AND THEY REFUSE TO PROVIDE ANY COMPENSATION OR EVEN ACKNOWLEDGE THAT IT IS A KNOWN ISSUE. THIS IS TOTALLY UNACCEPTABLE AND SHOWS A LACK OF COMMITMENT BY MERCEDES TO STAND BEHIND THEIR PRODUCT. I MIGHT POINT OUT THAT THEY ONLY HAVE 48 MONTH / 50K WARRANTY, WHICH IS VERY LOW TO OTHER VEHICLES WHICH HAVE A STANDARD 10 YEAR / 100K WARRANTY. THIS TELLS ME THAT MERCEDES DOES NOT HAVE THE FAITH IN THEIR CARS TO INCREASE THE WARRANTY. THIS IS A CAR THAT COST 100K NEW AND ONE WOULD EXPECT A BETTER WARRANTY AND SUPPORT FROM A COMPANY THAT TOUTS THEIR CARS AS BEING THE BEST. I CAN TELL YOU THAT I WILL NEVER BUY ANOTHER MERCEDES OR STEP FOOT INTO A DEALERSHIP. ON THAT NOTE, I CAUGHT MY LOCAL DEALERSHIP ATTEMPTING TO OVERCHARGE ME ON A PART BY $400. ONCE I PROVED WHAT OTHER DEALERS WHERE CHARGING, THEY MADE AN EXCUSE AND GAVE ME THE PART AT THE RATE THAT THE OTHER DEALERSHIP WAS CHARGING. WHAT A SHAME. BUYER BEWARE!!! *TR

THE SECOND TIME THIS HAPPENED WAS WHILE MAKING A LEFT TURN, I PRESSED THE GAS PEDAL AND THERE WAS NO RESPONSE AND THE CAR WAS REVVING BUT TRAVELING LESS THAN 5 MPH WITH ONCOMING TRAFFIC HAVING TO STOP SHORT TO PREVENT CRASHING INTO ME WHILE I WAS MAKING THE LEFT TURN. THIS WAS AGAIN RESOLVED WITH ME PARKING THE VEHICLE, TURNING IT OFF AND THEN RESTARTING IT. AFTER THE SECOND TIME THIS OCCURRED OUT OF NO WHERE I DECIDED ITS A VERY DANGEROUS SAFETY ISSUE. *TR
