I need help :-/
 

Please can you help me I bought a rebuilt mercedes c250 2012 in the sample place I always bought my cars before and this car was driving normal and randomly stop moving forward and would not engage in any gear! Next day start driving normal again few days later the same thing I took it to the Mercedes dealer and the said the axle shaft is loose but they told me first was the differential and try to charge me 5000$ for that! I took it back and I'm trying to figure out my self the car only have 10.000 miles and got hit on the door only also when it does that and I put in park makes a sound!
