Manifold/header/muffler/tail Pipe Problems of Mercedes Benz S550

There is an plastic plug in the oil system that leaks oil from the engine on to the exhaust manifold. This was reported because of increased oil consumption, vapor in the engine space and a smell of burned oil. The plastic plug is known to leak and mercedes does nothing about this during warranty and instead waits until the vehicular is out of warranty causing an increased time for a fire potential. This car is driven on city streets and highways with this fire potential.

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 committment 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!!!.
