Purchased car March 2015 with a 3 year extended warranty. Inside drivers door handle broke (plastic piece inside door I believe). Dealer claims warranty does not cover this because it is cosmetic and it will cost me in excess of $1100. To get it fixed. This is a major safety issue, one should not have to open the window and feel for the door handle to open the door. In many situations this could be a matter of life or death. This is just as critical as an air bag in my eye. I believe the dealer should cover this under the warranty, and may even warrant a recall.

I drove my car to a store, turned it off and left it for 10 minutes. When I returned the car would not start. I had a friend try to jump my 1 year old battery amd still no start. My display says to remove key when my key is in. Lights, radio, and locks work but no windows. Dealer says I need a new steering wheel column. This problem is posted everyone online. Seems like a common thing. Dealership says it'll cost me $1575 and take 5 days to fix.

I had just stopped in driveway in my house after a 15 mile drive from my office when I tried to open the door, the handle flapped about but did not engage the lock to open the door. I had to start the car again, rolled down the window (glass) before I could open the door using the out side handle. The local Mercedes Benz dealer and the Mercedes Benz usa representative informed that I have to replace the whole driver's side door at a cost of $708 after the local dealer discount. Mercedes Benz has installed a plastic handle as a door handle but requiring buyers to purchase a whole door when the plastic handle breaks. Is this allowed" even if this is allowed is it good for the customers? what can you do about this" as far as I am concerned they have lost a four-time Mercedes Benz customer. But I want others not to get caught in this money-pit. Please help.

When trying to exit the vehicle, using the driver interior door handle, the handle no longer engages to open the door. The driver must roll down the window to release the door from the outside to exit the vehicle. In the event of an emergency where the vehicle electrical system was not working, the driver would be unable to leave the vehicle.

I have 2010 Mercedes Benz C300, my car would not start with my key even though the battery checked okay. This is a very common failure among C300 models (2008 to 2013). So meaning cars are vulnerable to this failure around 5 year mark. Manufacturer should issue a recall on these parts, as they have a very bad reliability.
