Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted.
With only ten complaints on file for the 2015 Lexus RC F, the picture is thin but a few patterns stand out. Seats and the fuel/propulsion system each draw the most reports. On the seat side, owners describe squeaking and noise from the front passenger seat, particularly when using the power tilt function. Fuel system complaints center on two related concerns: high-pressure fuel pump failures requiring replacement, and a more serious issue where owners describe fuel leaking from the fuel line, attributed to what they say is a breakdown between the steel tubing and its outer plastic coating. Service brake complaints describe a thumping noise under hard or sustained braking, primarily felt at the front axle, a pattern a couple of owners say dealers characterized as normal behavior. A single report mentions the passenger-side HVAC blowing ambient-temperature air rather than cold, with a related fault code appearing around 25,000 miles.

Total Complaints
By System
The 2015 Lexus RC F has two recalls, both involving the fuel system: one where a cracked high-pressure fuel pump cover can leak fuel and create a fire risk, and one where a failing low-pressure fuel pump can cause a sudden loss of engine power while driving.
The high-pressure fuel pump issue involves a pulsation damper that can develop a fatigue crack in the pump cover under certain operating conditions, allowing fuel to escape near potential ignition sources. The low-pressure pump failure can cause the engine to run rough, refuse to start, or cut out unexpectedly on the road, with the check engine light potentially illuminating as a warning. Both recalls apply to vehicles equipped with the 5.0L V8 engine.
