Three problems related to engine clicking and tapping noises have been reported for the 2012 Mercedes Benz C250. The most recently reported issues are listed below.
I have been having issues with my vehicle since I purchased it. Starting with me not having enough power from a start, in an attempt to gain enough power to drive at a safe speed from the start, as if the vehicle lags & no matter the gasoline or service, the problem never corrects. When I'm trying to gain speed to maintain with the flow of traffic safely the vehicle lags notably before gaining speed. I'm now having to replace the engine bc the oil coolant hose burst while I was driving on the highway with my child in the car. My check engine light activated but the only notice displayed on the dash was the engine coolant when it was low. When the hose burst while I was driving about 60mph I heard a pop sound under the hood, saw smoke coming from the exhaust, then a clanking noise under the hood that got louder & louder until I was able to pull off of the highway, & then I noticed a very large amount of oil on the ground that left a trail along the ground from my vehicle. That was very dangerous as my vehicle lost power during that incident. I'm told by the mechanic, the engine has to be replaced. This happened without a warning. The Mercedes Benz is supposed to be a safe & reliable luxury vehicle & not a nightmare to have for the owner.
Purchased my 2012 C250 with 45k miles on it at time of purchase. I put 4k miles and I started hearing a ticking noise on start ups then progressed. It has turned off on me while driving at about 35 mph and another at 25 mph kinda scared to drive it. You think when you pay for quality you should get it, not having to $5500 for a camshaft lifter replacement in under the first 50k miles that' insane! please send feed back in going to talk to lawyers and get there view on the situation because there's more then just a couple with this problem and some with vary low miles. Thanks for your time much appreciated .
