Zero issues with this car until now. This week, June 2013, the car has 78,000 miles on it. I pulled up to a stoplight off the freeway, and the car started sputtering like never before. The check engine light came on - for the first time ever. The car stalled and engine died. It restarted, but when I pressed the gas there was no power, traffic was coming up the off ramp fast, I had to flash my brakes to get them to notice something was wrong but it was a close call. The car sputtered into the middle of a busy freeway overpass intersection with my family on board and eager traffic behind me. It was a very scary moment because the car went from completely reliable and trustworthy to complete loss of power and instability. I sputtered back home, creating the same dangerous conditions at every intersection. I took the car to a Mercedes Benz shop the next morning. After a lot of testing it was determined that the intake manifold needed to be pulled to look deeper into the engine. Hours later they found that the problem was caused by a defective plastic bushing of the intake manifold which broke and was sucked into cylinder #4 and #3. This caused the valves to bend and compromised the integrity of the cylinders and valves, according to the mercedes qualified technician. There is extensive damage to the valves, and they don¿t know what all they¿re going to find once they pull the headers off. The cost to repair the car is $4,400, but it may even be higher. The cylinders have to be sent to a machine shop to see if they have any other issues as a result. Who knows what they'll find. The mechanics stated that Mercedes Benz is aware of this problem, that those moving plastic parts in the intake manifold are known to crack and cause problems and should never have been made out of plastic, but I don¿t see recalls on this obvious engineering & manufacturing defect.

Problems began at 10,000 miles Aug 2002. Brought car to dealership 3 times since oct 2002 and dealership say their diagnostic tests show no problem and the stalling/rough idle is normal. They can't find any issues. Car stalls (depending on the weather)- worse on humid days, but everyday runs really rough upon start up. 50% of the time will completely stall. Other 50% if I gas the car, it runs really rough, but gets me out of my driveway. Car roughly switches to drive. Very little power when switching to drive and driving down the road. The car redlines until I get to about 20 mph and doesn't seem to switch to second (I have an automatic) until I get to 20-25. Power steering is not working on cold days- very difficult to turn wheel until car gets warmed up. Even on days when its 40 degrees f. On several occasions when it has been colder than 15 degrees, the steering wheel is completely upside down and you would think the car would not drive straight- it does!- which means the steering wheel and power steering is not working or my car would not be going straight. This is very dangerous and could cause an accident and I have no idea which way my tires are facing! the worst and most dangerous part of this is: on 4 occasions since December 2002 until February 2003, while driving on highway at approx 55 mph, went over a slight bump in the road and completely lost power in the vehicle and all warning lights (every single one) came on. Car immidiately halted to about 3 mph, the car behind me almost rareended me. I had my foot all the way down on the gas (I was in the middle of the road) and the power came back on within 30 seconds, and I almost rare-ended the car in front of me when my car surged forwarded.
