Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.

As per Mercedes Interim Recall Notice 21V042, one or more of the rear-wheel speed sensors may experience an electrical failure, which potentially could lead to a disablement of the Electronic Stability Control control unit functions. If ESP control unit functions are disabled, vehicle driving stability may be impacted under certain driving conditions, increasing the risk of a crash.

According to the attached letter from Daimler AG/Mercedes-Benz; ?Daimler AG (DAG), the manufacturer of the Mercedes-Benz Sprinter vehicles, has determined that the glass cover of the exhaust gas temperature sensor (upstream of turbocharger B16/11) on certain Model Year 2011 ? 2015 Sprinter vans could break when exposed to extreme high or low temperatures. This could result in incorrect temperature sensor readings. If this occurs the ?Check Engine? light will be illuminated and the vehicle will experience a loss of power and enter into a limp home mode.?
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
