The engine in my car died and after inspection by a Mercedes mechanic they concluded the failure was caused by faulty camshafts that have been common in the year and model this car. Mercedes has issued and extended warranty to cover the repairs recognizing this was a manufacturing issue but they are refusing to cover the full cost of repairing my car.
2012 Mercedes-Benz C250 engine complaints
Page 2 of 3: complaints 11 to 40 of 63, newest first, as owners wrote them.
The contact owns a 2012 Mercedes-Benz C250. The contact stated that while driving at 50 MPH, the check engine warning light illuminated. The contact was able to continue to drive the vehicle. The vehicle was taken to an independent mechanic who diagnosed that the variable valve timing solenoid had failed and needed to be replaced. The dealer was notified of the failure and advised the contact that he would be responsible for the cost of the diagnostic test. The manufacturer was notified of the failure through a voicemail message. The vehicle was not repaired. The approximate failure mileage was 52,000.
When accelerating to pass a vehicle the check engine light comes on and there is loss power. When this happens there is a huge potential of a crash. The car has to be shut off to try and reset this. When you are on the frwy this puts life at danger. The code is a p002 and if you research it Mercedes is aware of this and is most likely a defective high pressure fuel pump problem that needs replacing but there have been no recalls. I have looked it up on you tube and has been on ongoing issue with no recalls as of yet. I am taking my car to dealer on 11/15/2021 for this issue which they will charge me for even though its a safety issue
I purchased this 2012 C250 Mercedes from Carmax of Waldorf on 04/26/2017, with 20,046 miles on it. I informed Carmax the engine light was on and the car was rattling at start. I also reported the oil dipstick was broken. When the car was returned, the dipstick was replaced, coolant light off and engine light was off; however, the rattling at start up continued. I reported the problem to Carmax several months later and they pretty much denied fault and went as far to say the car is just cold and does that at startup. For further protection I signed with carshield as my wife drives the car. The car's rattling continued at startup and eventually became difficult to start. I took it to Mercedes of Arlington, Virginia and they stated the timing gear and chain needed replacing. carshield reported back to me that it was a preexisting problem and wouldn't fix it. Meanwhile, we were stuck with a car we were paying on with no one taking the blame. Following research, I found that this is a recurring problem with the 2012 C250 model but there is no recall. I eventually paid approximately $5000 for the engine to be repaired as the engine failed. The engine is currently rattling again; with the engine light coming on constantly. this seems to be a common problem, however, with to consequences and accountability.
2012 Mercedes C250 caught fire with no warning. Drove about 5 miles to the store and parked the car. A passerby said your car is on fire. Within minutes the entire front of the car was ablaze. The vehicle was towed to the city impound lot and has not been inspected by anyone.
When accelerating to pass on highway car suddenly goes into limp mode and losses power this is dangerous at 70 plus miles per hour, ECM code reads p0002 high pressure fuel regulator failure, check engine light will stay on until car has been shut off for longer than ten minutes or if you have a scanner you can erase code and drive the car normal, no passing. This has also happen pulling out from a stop light car has buckle with immediate power loss and will only creak up in limp mode just enough to get you home. I am a well season mechanic with over 20 years experience and this is absolutely dangerous. Please don't wait until someone gets hurt or killed by this which is a known issue going back before 2012. This happened 3 times this ast week and today.
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.
Cold engine vehicle jerking I took it to mercedes of fort myers fl and they told me that they couldn't find the problem and I took it to so many other places and still can't find it I'm just wondering if it could be a recall
2012 c250 purchased new from a dealer. Rattling on starting engine and check engine light is on. Spoke with my mechanic and it is due to faulty camshaft adjusters. Repair will cost $5000 plus and involves replacing the camshaft adjusters, timing chain and sprockets. This problem just started 10 days ago with approximately 38,000 miles on the odometer. Seems to be a well known problem and not an expense I can really afford on reduced income due to covid lockdown. I am very worried about driving this car as this problem can result in catastrophic engine failure and I am regularly on the freeway. Driving this car is no longer safe. I purchased a mercedes thinking their reputation for safety, quality and engineering would preclude such issues.
I was driving a of maybe ten minutes on the highway . As soon as I was off the highway ; the vehicle suddenly stopped without warning of a check engine light .(malfunction). Days before that the vehicle was serviced at a mercedes benz dealership without any issues. After their research I've been told that I need a new engine . There are complaints after complaints listed online in regards to engine failure, cam shaft adjusters etc. This is something that clearly needs to be handled . This could have caused a life threatening situation.
In a mercedes benz c250 2012-2014 there has been many reports across the united states where camshaft adjusters+timing chain components fail/break. This is a highly risk and safety matter that needs to be addressed by mercedes benz as recall. Being newer model cars, the timing chain and camshaft adjusters should not fail. Not even at 100k miles. Some of these models has had their camshaft adjusters+ timing chain fail at 46k miles. Why is mercedes not owning up to these factory faults? Why are new models that are not even 10 years old have this kind of issue? This defect can cause major accidents on the road. Cause you go at highway/freeway speed 60 MPH and your timing chain breaks, you can cause a major accident with other cars, and injure your own self and passengers. Can you imagine for those who have babies and drive these vehicles. Why is a hugecompany like mercedes not owning up to these defects? Instead they want to charge $4,000-$8,000 to get this repair done. Even if you have warranty they still hesitate on getting this repair done. I just want to be heard because being one of the many reports with this issue on these vehicles, it's concerning to see many of these vehicles still out on the road. When these parts have are failing, you will get a check engine light that reads "p034062" camshaft position sensor bank 1 electrical failure" after getting diagnosed by many shops, and even mercedes benz dealer all the test say the wiring and everything else is ok. Camshaft adjusters are failing will need replacing + timing chain & tensioner. But why on such a newer car? It should run about 200k miles until it needs a new timing chain. Cars being serviced at correct interval & being well maintained. This should not be a issue. Engine when start up will rattle. It will sound like engine is falling apart. Plus car will run really rough.
My check engine light came on while driving and I had it checked by a mechanic, the obc code was p0340 camshaft adjuster. My vehicle has less than 100,000 miles the camshaft adjuster should not need to be replace until around 250.000 miles. Other owner's of 2012 c-250 have experience the came issues. Mercedes benz should take note of possible defected parts.
Check engine light is on and upon quick acceleration the car misfires and begins to shake. Also having water come through top frame when it rains
Hello, this is a flaw in the mercedes m271 engine. After a certain amount of milage the camshaft and timing chain have been malfunctioning in most mercedes c250 cars. The dealer is asking $4400 for the repair, and mercedes did a recall on it years ago the camshaft adjuster solenoid is very faulty as it happens to most c250 vehicle owners. Ever since it happened to my own car every time I start it sounds like its about to blow up. The check engine stays on every day, sometimes it'll go in limp mode and I would carefully take the car off the highway.
My c250 started making a noise when you first start the car. Choking and hesitations to start, but yet would start after a moment or 2. The noise was unfamiliar. This noise would continue through out the day, as long as the car set for more than 15-20 minutes. I would go into the store, to shop come back out to the car an the noise would still be there after 15-20 minutes. I took my car to the mercedes benz dealer in houston, texas north. After a $200 diagnose cost. The cam shaft adjuster is out. Costing another $4,575.68. My car is a 2012, which I brought in 2014 with less than 7,000 miles. Now it is 2019 with only 87,885 miles on my car, I don't know what this part is for or why my car needs this. All I know it cost $4,575.68. Way to much for something I know nothing about. Can't get in touch with manufactory to complain and mercedes headquarter hasn't return my call. Please give me advise, as to what to do with my complaint.
Bought car from mercedes lot, used with 70k miles. Delivered it with check engine light. Salesman claimed it was low washer fluid. I said I wasnt going anywhere in a car with a check engine light and he needed to get it back to service and have code ran. After doing so he claimed it just needed to be reset since last service some work had been done(another lie). Told him I was retest driving before accepting vehicle. Turned over 3 times, then started. When driving on the interstate the throttle became unresponsive and died out with cars speeding up behind me. Forced mercedes to put it back in service. It was the timing chain and cam adjuster issue. Theres 100s of people notifying you of this. Mercedes knows and is trying to lie to customers and still sell them knowing they're damaged and dangerous. Fix can be upwards of $4000. A recall needs to be made!!! Please do something!
Dealership diagnosed problem with camshaft adjusters. This happened 2 times already on the same vehicle, and it is very costly to fix ($4000). First time I had a rattling noise from engine, and check engine light on. First time it happened at 46k miles. Second time car hesitates to start, had long cranking, it happened at 69k miles. It is a systematic, very costly and potentially life threatening problem.

Rattling noise coming from engine at startup. Diagnosed as defective cam timing adjusters @ 65000 miles. This apparently an on going problem with this particular part(s) and causes major engine damage. Repair costs range from $3000 - $5000 and more if the engine is ruined.
When starting car, there is an audible 3 second engine rattle before the engine fully engages. Once the engine is running, the vehicle appears to perform normally. The mechanics have diagnosed it as failing camshaft adjusters. The repair also entails replacing the timing chains. Repairs to cost just over $5,000. Commentary from the mechanic indicates that this is a very common failure with this engine which typically occurs just beyond the warranty expiration. Online searches have confirmed his assertion. My vehicle has 80,000 miles and has never missed a service. I have every receipt of every service. A critical engine component such as this with such a costly repair procedure should not be this common. It is the result of a poor design and at least a portion of the repair costs should fall on the manufacturer.
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.
I bought the certified car at 50k and at 70k miles, right after the warranty ended - check engine light came on and the dealership said it will cost $8k due to camshafts to repair!! They even suggested that I should consider trading the car in! Keep in mind I still owe $28k so that option is out! Since then the check engine light still on even after I got it repaired at a local/affordable mechanic and it's about 110k mileage and the engine is rattling as it runs. This is my 3rd benz and the first 2 failed due to the transmission failure. I just can't believe these german cars cause so many problems and so costly to repair. What happen to you pay for what you get!!! Today, while I was driving the car just slowly stop and the engine cut off! Aaa came to check and it's not the battery so will need to get towed. Still owe $10k left- I don't know what to do! No other car to drive .
Cam shaft adjusters went out and had to be repaired for normal use and drivers side door handle broke on the inside and needs to be replaced due to regular use.
Tl* the contact owns a 2012 mercedes-benz c250. While driving 70 MPH, the contact heard an abnormal noise coming from the engine. The vehicle was taken to mercedes-benz of covington (located at 8080 westshore drive, covington, la 70433, (985) 900-1212) where it was diagnosed that the camshaft gear-sprocket and exhaust cam adjuster needed to be replaced. The vehicle was repaired. The manufacturer was not contacted. The approximate failure mileage was 115,000.
Takata recall...engine making a loud rattle when started.
Engine light came on , the car hesitated to turn on at times, sometimes had to press the gas pedal to have vehicle turn on. Took it to local benz shops that claimed to work on benz, they said their computer could not determine the code. So took it to the dealer in fort myers, fl. Was told it was the timing chain and the 2 cam shafts. Was quoted $5032. So had to other choice than to have them repaired. Only received the managers discount of $150 (wow). I read that many other owners have the same problem and they will not recall . They have recalled older models like 2006 for this same type of issue. But of course seems that mercedes benz has no prestige. Also note this car only has 41,000 miles in mint shape take good care of it. Very , very disappointed with mercedes benz, don't get stuck buying a vehicle that is not dependable. This model has too many issues.
While starting engine light came on. Would not go away. Took to merc dealer,told camshaft failure. Replacement cost 5865 dollars. Car serviced at dealership as per recommendations. Several blogs report similar issue by different customers. Similar issue in e 350 on 2006 model. Merc seems to aware of this issue.
After only 75k miles my mb has a failing part that is well known amongst all mb dealerships. The cam shaft adjustment units both intake and exhaust have failed, causing me to undertake repairs in excess of $3k. For such a newer vehicle this is unconscionable and many dealerships around the phoenix area have known about this issue for awhile and have expressed shock that this hasn't been a recall issue yet. I knew there was an issue with my mb when I started it up and there was a rattling noise coming from the engine portion of the vehicle. Each shop and dealership I've taken it to have noted it and have stated that repairs range from $3k to $4.8k. Simply unacceptable. I am hoping the federal safety agency will investigate and recall this car for this issue as it is a well-known issue and needs to be addressed.
