The Toyota and Lexus low-pressure fuel pumps were built by Denso. The pump is located inside the fuel tank and contains an impeller that may deform due to excessive fuel absorption. The deformed impeller can interfere with the body of the fuel pump, causing illumination of the check engine and other warning lights.

In addition, the engine may run rough and the vehicle may stall while driving. Toyota says this typically will occur at speeds of less than 20 mph, but in "rare instances" a vehicle may stall at speeds above 20 mph.

Toyota says it noticed an increase in field reports about the Denso fuel pumps in June 2019. The reports indicated the vehicles suffered from engines running rough, engines that wouldn't start and vehicles that suffered a loss of motive power while driving less than 20 mph.

The automaker says the fuel pump problems occurred more commonly in southern states with hotter weather.

Toyota and Denso opened investigations and recovered the faulty fuel pumps, finding failed fuel pump impellers with lower density that makes the impellers more susceptible to fuel absorption.

Toyota initially determined the problem was prone to occur at speeds lower than 20 mph, but out of 66 reports, three of the vehicles stalled at speeds above 20 mph. The automaker says it issued the recall because of the possibility of engine stalls at higher speeds.

According to a report made to the National Highway Traffic Safety Administration, the automaker received 2,571 warranty claims about the fuel pumps in addition to the 66 field reports.

Some hybrid vehicles are equipped with the Denso fuel pumps, but Toyota says a vehicle will enter failsafe mode if the fuel pump fails. The hybrid driver will see illuminated warning lights and the vehicle can be driven for a while with reduced power.

The automaker says it will conduct a customer satisfaction campaign for the hybrid vehicles in the future.

Toyota says other vehicles are not equipped with the same fuel pumps produced in the same production period, or they are equipped with different pumps.

Toyota and Lexus are working on a remedy for the fuel pump problems, but owners will be notified about the fuel pump recall by March 13, 2020.

Toyota customers with questions about the fuel pump recall should call 800-331-4331 and Lexus owners may call 800-255-3987.

Toyota's numbers for this recall are 20TB02 and 20TA02, and for Lexus vehicles the recall numbers are 20LB01 and 20LA01.
