"Water pump"

Anonymous, OK (2017 Lexus RX Hybrid 450h 3.5-L V6 hybrid)

""The motors for the rear hatch were making a lot of noise opening. They had to be replaced at the beginning of this month. Two weeks before the problem began, one of my adult children tried to shut the hatch manually instead of using the button. Not good for an electrically controlled hatch.""

Fuel System/Emissions

Sensors (O₂, or oxygen, sensor), emission-control devices (includes EGR), fuel-injection system, fuel gauge/sender, fuel pump, problems filling up the tank.

What Owners Say

Fuel gauge/sender

"Periodically despite the fuel tank having ample fuel, the fuel gage will suddenly drop to empty during travel triggering alarms/notifications that the car must be refueled ASAP. It's happened at least 3 times in the past year. It has not been resolved because Lexus service says they can't identify the problem unless it's occuring at the time of service. Not great."
