Information for Owners
On certain Model Year (“MY”) 2021 S-Class vehicles, a nozzle in the suction jet pump in the fuel tank might not
have been installed, or proper1y secured, within the pump according to current production specifications. If the
nozzle was not properly secured, it could detach within the suction jet pump. If the nozzle detaches, the pump
might not be able to supply the fuel pressure necessary for certain driving scenarios (e.g. reduced fuel level, full
throttle operation), which could lead to a sudden engine stall without warning, which could increase the risk of a
crash.
An authorized Mercedes-Benz dealer will check the fuel system on the affected vehicles and replace the fuel tank,
including the suction jet pump, if necessary. This service will be provided free of charge. We are dedicated to
always delivering the best customer experience, and respect for your time is a top priority. While the minimum
repair time can be less than 12 hours, your dealer can provide you with a better estimate of the overall time for
this service visit. As a matter of normal service process, an authorized Mercedes-Benz dealer will also check for
other repair measures which might be applicable to your vehicle and this may increase the required working time.
For additional information and to schedule an appointment, please contact your preferred authorized Mercedes-Benz
dealer at your earliest convenience. To locate authorized dealers see www.MBUSA.com/recall. Please
mention you are scheduling an appointment to check the fuel system on the affected vehicles under
Recall Campaign # 2021090012. You may be asked for your 17-digit Vehicle Identification Number (VIN)
which for your convenience is located above your name at the top of this letter.
Impacts from COVID-19: Your health and safety remain our top priority. The Mercedes-Benz dealerships
remaining open for recall repairs and service are closely following the guidelines set forth by the CDC. Free
