The automatic transmission has developed a condition that causes the transmission to shift very roughly at low speeds. This shifting causes the vehicle to jerk and stutter when down shifting or shifting from 1st or 2nd gear. I have had a transmission service, replacement transmission, replacement radiator all installed to no avail. The condition is at best a nuisance, and at its worst a safety concern. This rough shifting occurs in the lower gears, and at lower speeds.

We would like to submit a complaint. We own a 2004 Clk320 which has presented with continuing problems. When we purchased the vehicle, the rear axle alignment was defective in which required realignment and rear tire replacement. At 21,937 miles the car presented with transmission shifting problems. The car would jerk/stall while being driven. It was very dangerous as it was difficult to merge with traffic, but most importantly, we felt we were going to get rear-ended and cause an accident. The Mercedes-Benz dealer service department diagnosed the problem which required the transmission to be flushed. Then again at 28,714 miles the vehicle presented with recurring transmission shifting problems, jerking & stalling.. we scheduled a Mercedes-Benz department service and the diagnoses was to replace the entire transmission replace at over $9,000. We requested that Mercedes-Benz of America replace or assist us with the repair of the vehicle at no cost to us the customer since the vehicle is a "lemon". the Mercedes Benz representative said that he would contact the dealer and get back to us within 24 hours. We never heard back from him even after leaving numerous voice mail messages. We have searched online and found numerous similar transmission complaints. This problem is extremely dangerous and is a safety issue and Mercedes-Benz should recall this vehicle.

I have black Mercedes C230 kompressor sports sedan 2004 model. Car was purchased brand new at Mercedes authorized dealer. There is no modification made to this car and all the servicing done at Mercedes authorized dealer since I bought this car. It had only 58000 miles. Last B servicing which checked any safety related issues and includes regular maintenance, was done at authorized dealer on 02/18/2012. No issue was informed on 02/18/2012 to us by Mercedes authorized dealer servicing department. On 06/21/2012, when I was driving this car from work to home, I turned on A/C, A/C shutdown and I started smelling smoke. On left side of my car there is A/C vent and I saw fire inside the hood through that vent.I pulled over car right away and electricity went out with in 1 min of my pulling over and within 4 min, whole car was burning. My car is now totaled. This poses following security concerns: 1. Mercedes C230 2004 is made of highly inflammable material and driver and users of car has very less chance to survive if there is fire. 2. Mercedes C230 2004 model A/C unit is not of highest quality and electrical system is faulty. Both of above issues poses very serious security risks to public and it needs through investigation. I contacted Mercedes head quarter for investigation and Mercedes declined to investigate. Geico stated in report that hood is stuck and cause of fire is unknown. Geico insurance company authorized Mercedes engineers to investigate further upon my request and Mercedes usa does not want to investigate further. I have pictures of burnt car and can share if it helps in investigation to rule out above 2 concerns. We do not want others to go through same ordeal as we went through.
