Owners of many different Mercedes-Benz models could see their car fall under a Recall that’s related to a recent software upgrade their car(s) may have received. Here’s the official word from NHTSA, while the vehicles that may be affected are listed below with their model years.

“A software calibration number (SCN) coding received on the affected vehicles during a recent workshop visit was incorrect. Depending on the model year and model affected, the results of an incorrect SCN coding can affect a number of vehicle safety and emission functions including the following types of functions: (1) the fuel gauge readings may be incorrect; (2) a stuck fuel-level sensor may not be displayed in the instrument cluster; (3) the OBD system may cause the check engine light to illuminate incorrectly; and, (4) the speedometer may be out of tolerance.”

What happens? “In the event of a vehicle crash, the electrical fuel pump may not receive a crash signal that is required for the fuel pump to disconnect and prevent future fuel delivery as designed.”
