— A DENSO fuel pump recall has been issued for more than 2 million pumps at risk of failing, causing engines to stall and vehicle occupants to become stranded.
The fuel pump recall is necessary because the low-density impellers in the pumps may deform from fuel absorption, causing the impellers to strike the outer parts of the fuel pumps.
DENSO says the impellers were exposed to solvent drying during production which caused cracks on the impeller surfaces.
According to DENSO, the defective fuel pumps were sold to these manufacturers:
- Magnuson Products
According to the DENSO fuel pump recall, a vehicle owner may notice the illumination of check engine warning indicators, an engine that runs rough or a vehicle that won't start. A failed pump while driving will cause the vehicle to stall and a call for a tow truck.
Affected automakers will announce their own DENSO fuel pump recalls as necessary to install pumps which have improved impellers made of higher density to decrease the chance of cracks and fuel absorption.
