There is a Subframe Replacement warranty!
 

I posted this over on the diesel side...but thought you all might like to know...

Took my 2014 E250 bluetec in for an alignment and some emissions warranty work today. When performing the aligment they discovered the rear subframe needed to be replaced and that was the cause of the problem.

Turns out that there is an extended warranty due to rust issues. And the warranty also covered the alignment.

It apparently covers several models, diesel or Gas etc. Link to NHTSA document here... https://static.nhtsa.gov/odi/tsbs/2023/MC-10233796-0001.pdf

SO I am getting out of dealership for $0!!! On a almost 12 year old car with about $130,000 miles!

Point being, if you need an alignment, it might be worth taking it to a dealership...

IIRC it is applicable to the GLK too.

20 years unlimited mileage!
