2011 ML350 Diesel Engine Seized - NEED HELP!
My wife's ML350's engine just seized and is currently in the shop awaiting a MB technician. The car has 15,000 miles on it and the service manager is telling me that the engine seized because the oil hasn't been changed and it may not be covered under warranty. How is this possible with only 15,000 miles?
I agree that its unacceptable for this to happen without extenuating circumstances. I wish you luck.

That being said, Mobil1 ESP Formula M 5w40 is a quality oil, and going 5000 miles over the "recommended" number will not cause an engine seizure. No way, no how. These engines run too well where 9 quarts of oil would sludge up that bad to cause a total lack of lubrication. For MB to use the number of a 10000 miles service interval, they must have tested engines past that number. And the test would have to be at least a few thousand miles past. BMW uses a 15000 mile interval in their oil service so the number is not that strange.
Here is a quote from the Mobil1 website.:
"In a controlled test, a 2009 Chrysler Sebring ran with conventional oil until the engine had formed significant sludge. Technicians then changed the oil, using Mobil 1 5W-30, and ran the vehicle for another 4,000 miles. After that one oil change, virtually all sludge had been cleaned up."
So if their synthetic oil is that well of a performer, I would rule out your going over the service interval as a cause. I am sure you are not the only one out their either who has done that. Just that others won't admit it.
Which brings up two things.
1)What did the repair shop actually do when
2)Tell you service adviser that if MB wants the oil changed every 10000, and you have done 1 oil change so far in S. Carolina, at 15000 total miles you are NOT over the limit. Your next change isn't due till 20000. You actually have 5000 miles to go.
Keep us posted.

Sorry but I think you are out of luck with warranty too many factors against you. The suggestions for service are there for a reason and I believe that you now found out why. Its your fault and it will be or should be out of your pocket.
We had a motor fail after only 7k in a Range Rover be cause when my wife got a low I
Oil warning then a over heat warning, she didn't believe the gages because "Well Rover electrics system had been giving us some faults readings" in our old Rov. Her Bad!!
Rover did cover the motor though, but that was back in the day when if you bought a high end vehicle you received top knotch service.

Why wasn't there a warning light? Why didn't the engine shut off before causing significant damage? Why did the ECM fail? Was there a defect in the engine that caused a significant sludge problem at 15,000 miles?
We are still awaiting MB's diagnosis...

If the ML was not serviced at 10,000 miles then it'll not start after 1,000 miles of driving as it'll have run out of AdBlue fluid. The DEF is due for refill around the same time as the oil change and the dash board will constantly flash a "no start count down" warning each time you restart the ML if you are past the service interval.
Also if the ML was serviced during the wife's trip and the wrong oil was used it's unlikely the ML would make it back home?
The OP should have the service paper work to verify what was done and what oil was used as well as if the DEF was refilled as well as the mileage when the service was performed.
There is no prerequisite for the ML to be serviced by a M-B dealer or authorized shop for the warranty to be covered.
Some here do their own oil change and so long as the proper receipts for the oil and parts are kept the warranty should still hold.
Or lack of oil causing the rings to bind in the bore.
Or overheating causing the rings to bind in the bore.
Or failure of the timing chain or other timing component.
These last two items could be totally unrelated to the oil supply. We would need to know why it failed before we cast aspertions against one or another party/factor.
I also agree that 15,000 miles without an oil change whislt not good, should not be terminal, as long as it did have oil, and was not driven after the oil pressure light came on.
Read my post again...The service indicator came on when it was supposed to. The "Check Oil" indicator is what came on before the engine seized.
Oh I see what you're saying - sorry. I was referring to the "Check Oil" indicator. I don't think these cars have a "Change Oil" indicator as oil is changed at the regular service intervals.




You need to find your documentation for the service that was done and provide copies to your service manager. If the proper service was done then warranty should cover the failure.
The 10,000 mile service is pretty simple, it amounts to an oil and filter change along with refilling the def tank. It would be hard for anyone to mess that up. The only question is were the proper products used. MB is pretty specific on the type of oil used and the oil filter has o-rings that must be replaced when changing.
There is absolutely no requirement to have your vehicle serviced by an MB dealer to maintain your warranty. You must only have the service performed with the proper spec parts.

My wife’s ML was in for service since Tuesday and is being picked up probably as I write this.
The ML loaner that she was given is literally 6,700 + miles overdue for the “A” service as it says on the dash..

So if this is any indication of how critical Mercedes feels servicing their vehicles on time is, I wouldn’t worry about being a few miles over or having the oil changed elsewhere. As long as the proper oil, filter etc were used..
Note to self- Never buy a CPO that was a service loaner…......Not that I ever would have anyway…
