Since I had received my car Class B-150 in 2008, I am suffering from it because of many Problems: 1. Brakes: it’s not up to the expected when needed (very weak), Makkar Agency has been informed of this problem and they made necessary maintenance (as assumed by them) till the expiry of the guarantee period; then they asked for a complete adjustment for the whole brakes system!!! 2. After this incident; I moved to Katameya Maintenance Center. During 2011 another problem has been appeared which is vibration and weird voices in the motor, they defined the disrepair as a problem in the Belt Tensioner and they changed it in September 2011. 3. The problem continued and they ignored our many complaints about it till the guarantee period of the Belt Tensioner has been expired. 4. In April 2014, the problem has been aggravated and the car became slow and the vibrations are increased where I suspected the gear box oil. 5. Care has been sent to the Mercedes Maintenance at Fom El Khalig and they reported that gear box oil is not the problem and it is in good condition and they have to change Belt Tensioner again. (already has been changed when the car was reading 30,800 km). 6. Three days after receiving the car, same problem appeared again. I resent it again to the same Maintenance Center (Fom al Khalig) where they reported that the car needs to change the main Control Board of the Gear Box!!! You will not believe that the car is reading now 47,011 km which is very weird and strange for Mercedes Benz with their GREAT HISTORY. From the above; I’m not satisfied at all with the car regarding all many disrepair's which affected my job and I consider the above as waste of time and money. When I chose to buy Mercedes I chose Name, Reputation, Strength and durability. I work as Engineering Director at and Engineering Consultancy Company for Petroleum Companies (as Business Card attached) and I’m sure that, Mercedes Benz with their large reputation in Egypt and Middle East and Internationally, cannot accept these many disrepair's for a car 47,000 km. I really, was going to buy the new CLA but now after all these happenings; I will not and will not recommend Mercedes for any of my acquaintances. I expect free change of this spare part and rechecking of the many frequent breakdowns of the car. Appreciating your understanding and your time. N.B. my car is in Mercedes Agency at fom al Khalig since Saturday 3rd of May and no answer till now
