PLEASE NOTE: This complaint/issue pertains to many nearly identical plastic intake manifolds sold as OEM, new or replacements for cars made in the last ten years- Dangerous perhaps fatal fires are likely not getting reported due to the nature of the cause. My car has a plastic manifold. When a fuel injector or fuel regulator fails, raw gasoline can collect in the plastic bottom. If more than a few drops collects, turning over the engine can cause, and did in my car, a massive explosion. Fortunately the blue & white cloud of smoke that filled my two-car garage did not ignite. Had it ignited my son and I might not have survived and our home may have burned. Not that your organization takes all complaints seriously, particularly when thousands of cars might be involved, but these cheap plastic manifolds present a real danger I believe could have already caused deaths and property damage. If you are a political entity I suspect you will ignore this. But at least a warning should be give to the public. We are replacing the fractured manifold but the replacement part is still plastic, too thin to survive what cars in the past would have survived easily.

THE 1996-2001 MERCURY GRAND MARQUIS WITH A 100% PLASTIC INTAKE MANIFOLD IS KNOWN FOR ENGINE OVERHEATING, EVEN WITH NORMAL USE, AND A COOLANT LEAK FROM THE FRONT OF THE MANIFOLD. THIS WILL OFTEN TRIGGER THE CHECK ENGINE LIGHT AND LOW ENGINE COOLANT WARNING LIGHT. THE ENGINE COOLANT LEAK IS FROM A FACTORY DEFECT, WHICH CAUSES CRACKING ON THE FRONT COOLANT PASSAGE OF THE INTAKE MANIFOLD. IN A VERY SHORT TIME, THIS LEAK WILL LEAD TO ENGINE OVERHEATING ISSUES, ESPECIALLY WHILE THE VEHICLE IS IDLING. THIS IS EXACTLY WHAT HAPPENED. I THINK THE CAR PART SHOULD HAVE BEEN REPLACED BY FORD WHEN THEY NEW ABOUT THE PLASTIC INTAKE MANIFOLD.

MY SISTER AND I'M WRITING THIS REPORT ON HER BEHALF. HER CAR IS A 2001 MERCURY GRAND MARQUIS. LAST MONTH, (FEB '07) WHILE DRIVING, THE CAR'S ENGINE SHUT DOWN SEVERAL TIMES. EACH TIME SHE HEARD A "BEEP" AND WARNING LIGHTS CAME ON- CHECK ENGINE, TRACTION CONTROL AND ANOTHER SHE CAN'T RECALL. AFTER A MINUTE OR SO, THE ENGINE WOULD START NORMALLY. SHE TOOK IT TO THE FORD DEALER, SAWGRASS FORD IN SUNRISE, FL. THE PROBLEM RECURRED AND SHE AGAIN TOOK THE CAR TO THE DEALER. THE LAST TIME THEY FOUND A TRANSMISSION PROBLEM AND REPAIRED IT. (THE TRANSMISSION HAD BEEN GIVING PROBLEM, BUT SHE TOOK THE CAR TO REPAIR THE SHUT-DOWN PROBLEM). YESTERDAY (MAR 1, 2007) THE ENGINE SHUT DOWN 4 TIMES ! EACH TIME SHE HEARD THE "BEEP" AND WARNING LIGHTS ILLUMINATED INCLUDING TRACTION CONTROL AND CHECK ENGINE LIGHTS. SHE WAS ON HER WAY HOME AND IT NEARLY CAUSED AN ACCIDENT AS ANOTHER CAR ALMOST RAN INTO HER. THE CAR IS TO GO BACK TO SAWGRASS FORD (FOR THE THIRD TIME) ON MONDAY, MAR 5 '07. THE CAR WILL BE TOWED, NOT DRIVEN, AS THIS IS A VERY DANGEROUS CONDITION, ESPECIALLY AS POWER STEERING AND POWER BRAKES ARE LOST ON SHUT-DOWN. INTERESTINGLY, I HAD THE SAME PROBLEM WITH MY 2000 GRAND MARQUIS IM MAY AND JUNE 2005 . I REPORTED THIS TO YOU (NHTSA) AND YOU WROTE ME BACK, ASSIGNING REF.# 10141074. MY PROBLEM WAS FOUND TO HAVE BEEN CAUSED BY A SINGLE DEFECTIVE SPARK PLUG ! THE PLUG WAS REPLACED AND THE CAR HAS FUNCTIONED NORMALLY SINCE. THE REAL PROBLEM WAS WITH THE PROGRAMMING OF THE POWER CONTROL MODULE WHICH WAS CONFUSED AND OVERWHELMED BY ONE BAD SPARK PLUG. IN 2005 I WROTE NUMEROUS LETTERS TO FORD AND THEY WERE COMPLETELY UNRESPONSIVE. ENGINE SHUT-DOWNS ON MERCURY GRAND MARQUIS ARE A SERIOUS SAFETY ISSUE AND SHOULD BE CORRECTED. SINCERELY,
