Takata recall. Horrible noise coming from engine. Scared it is the dreaded camshaft and timing chain combo. It is ridiculous this has yet to be recalled by mercedes. Not safe as the car can leave you stranded without notice.

The contact owns a 2012 mercedes-benz C250. The contact heard an abnormal noise coming from the engine compartment when the vehicle was started. The failure occurred without warning. The vehicle was towed to mercedes-benz of san diego in san diego, CA where it was diagnosed that the cam shaft adjuster was defective and needed to be replaced. The failure was not repaired. The manufacturer was notified, but only offered the contact a discount towards the cost of the repair. The failure mileage was approximately 49,000. The VIN was not available.

The contact owns a 2012 mercedes-benz C250. Upon starting the vehicle, a loud noise was heard coming from the engine compartment and the service engine indicator illuminated. The vehicle was taken to an independent mechanic where the contact was advised that the camshaft and timing chain needed adjustment. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 56,000.

When starting up the vehicle make a terrible noise that last for 3-4 seconds before it goes away. The vehicle was verified by a mercedes technician and the diagnostics came back stating an issue with the "camshaft adjusters (internal fault)". I was told this condition will get worse and finally engine will stall and major damages will happen. Worst scenario could produce bent valves and will require a major engine overhaul with just 48,304 miles on it. Apparently, C250s are having this issue and customer are paying the consequences for a defective product. By the way, engine has been perfectly maintained with mobil 1 (ow-40) and original filter every 5,000 miles instead of the 10,000 miles interval recommended by the manufacturer. This condition could lead to a major failure while driving the vehicle that could end up into an accident.

Intermittent "inoperable mode" illuminated since mileage 41974. Car decelerated on the highway from 75mph to 10mpl nearly causing an accident. Pulled over, turned off vehicle, was completely shaken up. Waited about 5 minutes, restarted and it was normal. This has happened 13 times in the 6 months of ownership. Dealer was unable to duplicate issue. Vehicle again duplicated the same problem, I made a left turn, attempted to accelerate on a city street and it began showing the "inoperable mode" and check engine light again. A month later, the engine was making a loud noise like rocks in a dryer. Pulled over immediately away from traffic. I contacted the dealer, they said to "drive it in". On the way, the car broke down. Called mercedes customer care, they sent a tow truck. Car is under warranty until 50k, and is at 49404. While my 2013 C250 is in the shop, they issued me a 2016 c300 with less than 550 miles on it. After driving for only 5 days, it also has the check engine light and says "collision prevention assist plus inoperative". I notified the service advisor and he will not return my messages to have another vehicle issued. This is clearly a manufacture defect that mercedes is blatantly ignoring. This is stressful and heartbreaking that I have owned the vehicle 6 months, with a mountain of "manufacturer warranty" issues, they are asking me to pay the $2500 if it is deemed "not warrantable". So I am supposed to trust mercedes to be honest at this point? the only contact I have received since is that they will be charging me $2595. 00 in labor to disassemble my engine so that they have a "concrete answer" as to if my vehicle will be warrantied. It is under warranty and all services have been done as mercedes advises. For mercedes to not warranty it would be a direct violation of the manufacturer warranty and further prove their negligence.
