2007 Mercedes-Benz CLK550 Problems
Going over large bumps in convertible models may cause the roll bar to deploy, rendering the roof inoperative. Special tools are generally required to return the roll bar to its stowed position.
The sway bar end link joints may wear and cause a knocking noise over bumps. Loose or warn links should be replaced to correct this type of noise.
Computer control modules for the seats and doors, the CD changer, and the brake lamp switch tend to fail.
The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

2007 Mercedes-Benz CLK550 Reviews
This has been a great car for me. Have not had any problems with it since I bought it used in 2010. The convertible top has always worked good as well. I am always getting compliments on what a beautiful car it is. The Mercedes Benz dealership even had it showing in the show room with all the new cars because it was so nice.
I had a 2002 black on black corvette before my Benz. It was totaled in the great flood of 2010 in Nashville, TN. The 2007 Benz is what I replaced it with. The only reason I gave the Benz 4 stars in suspension & Steering was because I had been use to corvette's for 10 years prior to this and I don't think anything in that price & category compares to the vette for steering.
Having had any real problems with my CLK 550, just a little wear and tear that was under warranty. Great handling, love the power of the engine. Great curb appeal.
