While driving on the highway my my Mercedes Benz C300 2015 with 37000 miles, engine broke, and you are not expecting that when you are driving at 65 mph. The mechanic is saying it is a wrist pin and a cracked #1 piston and it is a very common issue on that car and Mercedes refuses to recall or fix the problem im going to leave a link with one of the many webpages with al lot of people complaining about that problem. Thank you. Https://mbworld.org/forums/C-class-W205/731642-W205-C300-stay-away-piston-cracked-65-K-miles.html

While the vehicle in motion, hearing a loud sounds coming from the engine. At first it's sounded like a rock in a tin can, later it was a slapping sound. About 10 minutes later finally got off the highway and turned in to my neighbor hood. At the last right turn, the car seized up. Tried to restart nothing happened. Good thing it was around 11pm there was no traffic or as many cars on the road. If it were it could probably just stop on the middle of the highway. The car is at the dealership and saying it needs a new engine, costing about 13K. Which is absolutely ridiculous, there was no signs of engine problem, engine light wasn't on. Out of no where, engine locked up and I had to push it home.

Dont know which category it falls. I bought this car in August 2015. In one week it would not start even. Towed to dealership and they said, the grounding screw was loose. I am so surprised that a car comes out from factory with a loose grounding issue. In the last 2 weeks, the car just stalled at the signal. All lights came up. I had the eco start/stop mode on. This happened 3 times and finally I shut the eco start/stop mode down. It is so dangerous that in heavy traffic, when people are ready to drive on change of signal, the car wont move, people are honking and frustrated and I am too. Looked online and so many people are complaining the same. The whole of dashboard lights up like when a car stalls. This is very dangerous. Anybody waiting behind you can take the pedal from the brake and smash into you. Similarly, for last 2 months, I have noticed that there is a jumping nature when you take leg of the brake at the signal. That scares me as well. From the feel of it, I feel this is primarily a software issue where the computer thinks it is in some mode when it is not or something and shuts everything down as a precautionary measure or something

While I was driving on the highway & local roads, the car suddenly became unresponsive and started showing messages that all systems are inoperative. Pre safe functions limited, and inoperative traction control light comes on along with the blindspot not activated, esp system was off as well. The car started slowing down and had to be pulled over to turn off and on. This has happened 3-4 times and on busy roads, car is sent to the shop and only has 27000 miles. I am scared to drive as I could die in a car accident because of this [xxx] car. Mercedes need to recall this asap, if they are not then we should open a class action lawsuit against them as they are playing with our lives.

New vehicle purchase 07/11/15, has been in/out Mercedes shop since the date of purchase due to electrical problems where car was flooded by rain when purchased due to a plug was not placed in the car by the manufacturer. Requesting a replacement due to electrical problems multiple times with being stranded. Vehicle would die and not crank with having to pull over to the side of the road multiple times due to vehicle malfunctioning. Vehicle was recently towed due to entire system went out and was stranded with vehicle not cranking when parked and died completely. Vehicle electrical system was recently found to be corroded and was changed out multiple times. Vehicle is currently running like a truck since this last repair. This vehicle is a lemon and should be replaced due to the lemon law and the vehicle was flooded by rain due to missing plug from manufacturer day one of purchase. Just received the car back 10/26/16 after two weeks, with the vehicle being in for dying and malfunction due to electrical problems. I'm afraid to drive this vehicle for a distance due to the electrical problems and in fear of being stranded again, with Mercedes having no guarantee for my safety. Vehicle VIN# at Mercedes shows all the problems with this vehicle being in/out of the shop for electrical problems and malfunction as well as changed out electrical system twice. Vehicle problems started September 2015. This vehicle is considered a lemon and I should be given a replacement due to this vehicle being flooded from the rain and having ongoing electrical problems. This vehicle has hindered me from traveling and has caused me frustration due to all the problems. This vehicle should never be allowed on the road again due to flooding and electrical problems and can cause a death. Mercedes is being negligent, with trying to repair and not salvaging as the lemon law requires.
