I bought the c230 at one year old. I had e perienced two times thatwhile freeway driving all power would be lost. Pulled over and put in park, rev engine a bit but RPM's would not move. Fast forward to december 2008 I sold car go my mom because I had a baby and car was too small. My mom since having car has lost power while freeway driving a total of six times now. Very dangerous as there is no "code" or "error" for mechanic when diagnosing, nor is benz ackowleding ghe issue.

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.

Took our daughter's 2006, c230 mercedes benz to our mercedes certified mechanic to repair a sluggish problem that caused the check engine light to come on.. I was informed that a part in the engine called the balancer was going bad... The cost is an approx $5000.00. And that we would have to take it to the local mercedes dealership to do the repair. The part installed in the 2006 and 2007 models was made of a too soft a metal, so its a defective part to start with! This part apparently causes the engine to lose power while driving... Benz has not issued a recall on this part.

2006 mercedes c230, loss of power and acceleration. First time it happened when the mileage was 62k. I was driving on shennandoah valley then suddenly the acceleration and engine power keep decreasing though my foot was completely pressing on gas pedal. I decided to full-over to cool down the engine. After re-starting it, the problem went away for awhile and back to normal driving condition. Then it happened again when my car had 65k miles, I experienced the same problem but this time from a complete stop from traffic light, when I tried to accelerates.. The car was no acceleration at all though the pedal was completely to the metal. This will be a very bad situation when all of a sudden it will not accelerate to normal running condition, when I needed to enter the highway to merge to a fast moving traffic.

I purchased my 2007 mercedes c230 in approximately february 2011 from carmax in roseville, ca. Within six weeks, I was driving on a local freeway when I experienced a loss of acceleration power yet the engine was running a over 4000 RPM. I returned to the carmax dealership to report the engine problem, but the dealership could not recreate the problem, which repeated itself intermittently in the following months. In december 2011, I took the car to a local mercedes specialist for a service b; upon examination, the specialist advised me that the car had not received a 60,000 mile service b, including a transmission service, and asked if the car had exhibited the power loss and high RPM. The specialist informed me that a mercedes service bulletin advised of an incompatibility between the metal material of the transmission and the original factory fluid, which causes a shearing problem and build up on the transmission shifting sensors. The specialist recommended and performed a service of flushing & replacement of the transmission fluid with a newly formulated, mercedes recommended fluid. Immediately following the service and fluid replacement, there were fewer incidents of power loss. In recent weeks, six months after the transmission service, the issue of power loss has re-occurred frequently, multiple times per week, multiple times per day, many times on the freeway at speeds of 55-65 MPH, requiring me to pull to the shoulder of the freeway to turn off the car an allow to reset before re-entering the flow of traffic. This loss of power and transmission control while driving at freeway speed is a great safety concern to me.
