2015 C300 problems
Hello All,
I am new to the forum and I am here because I just purchased a 2015 c300 with 71k miles. Unfortunately I did not do my due diligence before buying the car and have dug up a lot of issues these cars are having.
my model fall in the range of the cars affected by the “wrist pin” issue and the dealer says it was never corrected. Obviously the car is out of warranty and the repair is pretty expensive.
I have heard a lot of people complaining about cracked cylinders and I’m trying to figure out whether or not this is related to the wrist pins? I am also assuming there is no active recall yet for this issue and if you are out of warranty you are basically on your own? Does anyone know because I have seen some people say yes it causes engine damage and some people say it’s purely a noise for a couple minutes until the engine heats up?
also, I have noticed the car kind of shifts rough. Not anything crazy but just doesn’t seem like how a Mercedes should shift. I had an 09 c300 and I barely felt it shift. Dealer says tranny service was due at 60k so I am going to do the fluid and filter this week. Does this car have a drain plug for the torque converter and if it does is it recommended to drain the TC? The spark plugs are also worn so I will be replacing those I have read that this could cause some rough shifting and rough idle.
sorry for all the questions and I hope you guys can help me out! Thanks a lot!

The VIN range for "possible wrist pin issue" is exactly that - the affected units fall within that VIN range - and "most" in that VIN range do NOT have a wrist pin issue.
You need a valid diagnosis by a competent Tech - because if you have wrist pin issue you need to DUMP THE CAR - since a genuine wrist pin issue is a Time Bomb.
At the same time you are saying "I MIGHT HAVE A TIME BOMB" you talk about Tranny Service and Plug's - GET THE WRIST PIN ISSUE DIAGNOSED BY A COMPETENT TECH NOW !
Remember - with the Higher Pressure Fuel Injection System - with hood-up - YES - the C300 engine is noisy/metallic/slapping sounds from the Fuel Injectors as they close as fuel pressure now are so high as the injectors close it's like a metallic/knock sound.
!st things 1st buddy - keep the beat !

Yeah man I get what you’re saying. I put a good size down payment on this car and have a loan on the car so it’ll be hard to just sell it I just got it. I am still within lemon law time frame and mileage I do not know if that will help but in my state you cannot return the car. I have to pay them $200 to have the sound diagnosed and I really don’t want to do that when I’m sure it probably has the issue. If they were using the wrist pins that had too much tolerance odds are they went into ALL cars until they recognized the issue in April of 2015. My mfg date is 09/14 and I’ve heard nothing but horror stories.
never again will I buy a Mercedes. Has anyone filed a class action regarding this yet? I’m just mind blown that a Mercedes would last half the time of a POS Ford motor and it’s double the price and Mercedes refuses to make this right unless you are in warranty.
I bought the car with 70k on it and had no idea about the issue when I bought it

Look - sorry to sound harsh - but you ONLY HAVE A WRIST PIN ISSUE IF DIAGNOSED BY A COMPETANT TECH.
You can circle around with "thinking" all you want - but FIND A MB TECH BUDDY.
Don't you think during the 1st 4yrs/50K miles that a Dealer during service would have passed that by ?

MB dealer said the car wasn’t serviced as much as it should have been. They wouldn’t release the previous owners maintenance records for whatever reason? I don’t need the persons name just what was done to the car. To have the car diagnosed it’s another $200. I’ve seen videos of the wrist pin issue and mine sounds similar idk it has a clicking noise when the car gets down to about 1200 rpms during decel.
your right I need to just pay the $200 so I know for sure but that doesn’t really get me anywhere if they come back and say yeah you have the issue I’m still stuck. I don’t have the 11 grand to rebuild the engine out of warranty and even if I did who would do that to a 6 year old car anyway? I just bought the car with a 6k down payment so odds are I’m never gonna get my money back trading the car in. There is a lien on it so I can’t sell it outright. I’m stuck man. The only option is getting one of those bull**** car shield warranties but they wiggle their way out of most repairs through some loophole in their contracts.
so either way I’m screwed. And I know your not trying to sound harsh I appreciate the help man but I know you’re saying most cars do not have the wrist pin issue but if worst pins that were too small were being put into the cars odds are they went into all the cars until it was discovered. Mine is within the vin ranges and built in Tuscaloosa AL where they said the issue was taking place

So you know when you called/ a Dealer and said "I am-buying/have-bought a Mercedes not-from-Mercedes dealer and can I have the Service Records on my car" - the Mercedes "VMI" master record is Internal Only , which is not only a MB instruction, but holds true across Service records in our State (and many other states as well) - so what you were told was not specific to you/your-MB.
So you know.....let me just "ballpark" it for you - in that VIN range - we check every one that comes in for Service - whether under or not-under warranty - in that VIN range for every 50 C's we see for Dealer Service - we maybe have "1" maybe come up.
Yes - we have seen a "few" more with this wrist pin issue brought into us after they blow - C's we have not seen at our Dealership before - but this is definitely not a pandemic - and NO it doesn't affect all C's in this VIN range.
You need a Tech who has "seen/heard" the wrist pin issue before - nothing less will settle your worry - out of 20-30 C's brought in by Owner's who say "I positively 100% know I have the wrist pin issue - my MB sounds exactly like the ones on YouTube - what are you going to do for me" - our side takes about 20min to diagnose with experience "maybe" 1-2 of those 30 actually had a wrist pin issue.

Well that eases my mind a little. Yes I heard that Mercedes will not release the previous owners service history but they do upload a general description to carfax which I checked yesterday. The car has had multiple “vehicle health checks” both while it was in warranty and I actually just did one last week and paid the $200 for the vehicle health check. I called them and have been arguing with them that seeing if the car has the wrist pin issue should have been part of my vehicle health check why should I have to pay another $200 for a seperate diagnosis when that should have been included in the first place.
I mean I’m sure a lot of people are like omg I have the wrist pin issue of they hear one little sound off and I’m kind of paranoid because it’s so much money and I don’t want to be out all that money. Do you think the car would have even lasted the 71k miles it has now if it had the issue? Also does letting the car warm up prior to driving it if it does have the issue help reduce the wear?
I appreciate your help man and tomorrow I am bringing it back to Mercedes here in greenwhich ct to argue with the service manager about the wrist pin issue being checked when I paid the $200 a week ago for the vehicle health report.
don’t you think after that internal service bulletin came out they would have fixed the issue while it was under warranty if they thought the car had the issue? I mean like I said it has had like 3 or 4 vehicle health checks a few years ago while it was under warranty.
again I really appreciate your input and thank you
