I started doing some research today on the subject since I am almost at 20,000 miles on my 2013 Solera "S"/2012 Chassis and want to get the latest computer updates and service checks done, etc. Called the local Freightliner which is closer to my house and was told by the service manager there that they can no longer due Warranty Service on Mercedes-Benz Sprinters due to some dealer politics, even though Freightliner is owned by Daimler AG. Called the closest Mercedes-Benz dealership to my house to find they do not service Sprinter trucks-"GO FIGURE!"
I hope I am out of state when my Sprinter hits 20,000 miles!!
