Mercedes-Benz Recall Issued Over Fuel Pump Problem, Loss of Power Risk
A recall has been issued for nearly 144,000 Mercedes-Benz vehicles, due to fuel pump problems that may cause the vehicles to suddenly stall and lose power, increasing the risk of an auto accident.
The U.S. National Highway Traffic Safety Administration (NHTSA) announced the Mercedes-Benz recall on June 29, indicating that a defective part used during the manufacturing process may cause the pump to suddenly fail while the vehicle is in motion, which can result in a loss of power.
In the event of a fuel pump shutdown and loss of vehicle drive power while in motion, the vehicle will lose its ability to continue moving forward, which could lead to an accident and injuries, the NHTSA warns.
Mercedes-Benz and its parts supplier opened an investigation into the fuel pump issues in June 2022, following multiple reports from outside of the U.S. involving an inconsistency in vehicle power. The manufacturers analyzed the fuel pumps of the affected vehicles and conducted various tests which identified patterns of swelling, structural damage, and flawed impact resistance.
The investigation revealed that the material used to manufacture the fuel impellers was inconsistent across several batches, and that certain fuel delivery systems did not meet the required durability specifications.
As a result of the manufacturer error, Mercedes determined that the manufacturing error can lead to deformities of the pump’s impellors, which can result in a shutdown of the pump and complete loss of power while the vehicle is in operation.
While no accidents or injuries have been linked to the Mercedes-Benz fuel pump failures, the automaker has received at least 2,031 warranty claims, field and service reports related to the problem.
