Some 2015 – 2016 model year FR-S vehicles may exhibit a condition where the engine idle speed fluctuates (typically 500 – 1000 RPM) only when the transmission is in the Park or Neutral shift position. This condition occurs after the vehicle has been driven about 25 miles or more at highway speeds. The Transmission Control Module (TCM) logic has been revised to address this condition. Use TSB 0021-15 to address this condition. This repair is covered under the Toyota Powertrain Warranty. This warranty is in effect for 60 months or 60,000 miles, whichever occurs first, from the vehicle’s in-service date.
