Manifold/header/muffler/tail Pipe Problems of Mercury Mountaineer

2006 Mercury Mountaineer. Consumer writes in regards to failure of the water manifold housing. The consumer stated he was driving 70 mph, when the engine light illuminated. The vehicle began to overheat and steam was coming from under the hood. The water manifold housing had come apart, allowing water to boil out. The housing was plastic and made of two parts. The top and bottom were glued together and within the total circumference of about 18 inches, there were only three bolts between the top and bottom housings to secure the two parts together, except the glue. The consumer believed the construction was not enough to keep them from separating under pressure. It appeared, the design created a tendency for the top plate to pull away from the lower housing. The consumer attempted to install a new housing, but he discovered the engine was misfiring, so the vehicle had to be towed to the dealer, where the long block assembly was replaced.

I have 2 broken bolts on my rt side exhaust manifold and once and a while can smell exhaust fumes in the truck. I've taken it to five separate mechanics for diagnostics the repairs are very expensive and everyone said there should be a recall for this.

Gasket on the manifold failed. Yh.

The manifold on the right side of the vehicle has a bad leak. Yh.

The exhaust manifold has failed more than once; therefore, leaking a considerable amouunt of carbon monoxide which causes passengers and driver to become sleepy.

The exhaust pipe had some way bent which caused the pipe to get close to the rear fender. The rear fender was made of some sort of plastic which melted from the exhaust pipe. The owner was told "the only way that the pipe could have been disfigured if you ran over a speed bump". The owner does not recall doing that or over loading the truck. Ts reconditioned bumper, absorber, reflector had to be replaced.
