What is the known low-pressure fuel pump failure issue for 2019-2020 Lexus LS models, and what should owners expect?
Certain 2019-2020 Lexus LS 500 and LS 500h vehicles are covered by NHTSA recalls 20V-012 and 20V-220 due to a Denso low-pressure fuel pump impeller that can swell, restricting fuel flow. Symptoms include fluctuating idle, hesitation, difficulty restarting, warning lights, or sudden engine stall, which increases crash risk. The repair is a free dealer replacement of the fuel pump assembly under the safety recall, so no out-of-pocket cost applies for owners who have not yet had the remedy performed.
