I find it interesting that with all of the "exceptional German engineering" there are so many fairly serious problems with these cars. I have a CLS 63 AMG have had several problems that I suppose would be considered not all that significant however I do not think they should have occurred on a $100K car. One cam replacement at 36,000, miles, wheel bearings at 38,000, brake rotor replacement at 41,000 (dealer ship error - had one stuck and beat it off with a hammer. Results - no brakes when backed out of the service bay. They ended up replacing the brake booster, computer and all four rotors.), both front air struts at 58,000 miles, fuel tank replacement due to leak 73,000 miles, A/C compressor at 76,000 miles etc., etc. etc. I am religious about maintenance and have each problem fixed as soon as I recognize I have one. I also have an extended warranty. I won't buy another Mercedes but might go with an Audi if they ever make one as sexy as the CLS 63. Lexus builds a great car but they are so damned ugly! Mercedes is not highly rated for reliability these days. Several manufacturers have much better ratings and I believe Mercedes vehicles are highly over rated and over priced. "You get what you pay for" does not apply here.

I can see this being a problem with the 90s AMG but didn't know it still happened today! Wow

2004 and 2005 C55 and CLK55 are the most reliable and cheapest to maintain AMG models you can buy ...
Zero problems with mine apart from normal maintenance items,,,which includes a new CPS , valve cover gaskets and new front upper control arms due to rubber bushing deterioration,,,it is 14 years old after all..
No breakdowns ,,,no malfunctions,,drives beautifully,,
Treat them well , don't neglect servicing and they will pay you back.
Just like a good woman.

As they say KISS, Keep It Simple Stupid - horror stories galore on these engines. Some of the most basic engineering failures - wonder how many engineers got fired.

I have a friend that had the C63 and drove it hard trying to blow it up with every push of the accelerator. That car never missed a beat, it ran faultlessly.
He also bought a used ML63 from a lady owner that drove it around the city. Bought at auction with flat battery and no key. (Bad idea)
Anyway the engine had worn out cams and bent valves. I replaced it with a second hand one for him.
Moral of the story is high performance engines are exactly that they should be drivin hard and not bought to drive to school, soccer and yoga. I believe the M156 engine needs to live most of its life up in the high rev range to keep the oil pressure up to the back of the cams. Obviously thatís not always possible and Iím not saying itís rite but it seems every engine we looked at had worn cam lobs towards the rear. So that is an engineering fault for a domestic car.
Not many 63ís are driven hard enough I think.

I thought it was interesting that his post contained exactly 100 exclamation points.
