Source: classified from NHTSA complaint and recall data. "Battery-related" includes high-voltage propulsion battery, charging system, hybrid drivetrain, electric propulsion, regenerative braking, 12V auxiliary battery, and thermal-event complaints. Other complaints (suspension, steering, brakes, infotainment) appear in the engine and vehicle-level sections. Rates are absolute counts, not normalized per-VIN — high-volume models naturally produce more raw complaints than low-volume ones. Self-reported death and injury counts are capped per complaint to limit form abuse.

The diaphragms in the fuel pulsation dampers may harden over time and develop cracks, possibly causing a fuel leak.
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2007-2010 Lexus LS vehicles manufactured May 9, 2006, to July 20, 2010, 2006-2011 Lexus GS vehicles manufactured January 6, 2005, to September 10, 2010, and 2006-2011 Lexus IS vehicles manufactured August 30, 2005, to September 10, 2010. Due to anti-corrosion plating remnants, fuel may leak from where the fuel pressure sensor is attached to the fuel delivery pipe.
Toyota is recalling certain model year 2007-2011 Lexus GS350 vehicles manufactured June 19, 2006, through July 12, 2011; and model year 2006-2011 Lexus IS350 vehicles manufactured May 27, 2005, through July 13, 2011; and model year 2010-2011 Lexus IS350c vehicles manufactured November 25, 2009, through July 19, 2011. These vehicles, equipped with the 2GR-FSE engine, use bolts to secure the housing and sprocket of the Variable-Valve Timing (VVT) system gear assembly. These bolts could become loose due to abnormal impacts generated within the gear assembly immediately after a cold start-up.
TOYOTA IS RECALLING CERTAIN MODEL YEAR 2006 AND 2007 LEXUS GS300 AND GS350 ALL WHEEL DRIVE (AWD) VEHICLES. THERE IS A POSSIBILITY THAT THE PLASTIC PAD EMBEDDED INTO THE FLOOR CARPET MAY INTERFERE WITH THE OPERATION OF THE ACCELERATOR PEDAL.
TOYOTA IS RECALLING CERTAIN MODEL YEAR 2006-2009 LEXUS IS AND MODEL YEAR 2006-2007 LEXUS GS VEHICLES. DUE TO INSUFFICIENT TIGHTENING OF THE FUEL PRESSURE SENSOR CONNECTED TO AN ENGINE FUEL DELIVERY PIPE WITH NICKEL PHOSPHORUS PLATING, THERE IS A POSSIBILITY THAT, OVER TIME, THE PRESSURE SENSOR COULD LOOSEN. IF LOOSENING OCCURS, FUEL COULD LEAK PAST A GASKET USED IN THE CONNECTION BETWEEN THE SENSOR AND THE PIPE AND THROUGH THE THREADED PORTION OF THE SENSOR.

TOYOTA IS RECALLING CERTAIN MODEL YEAR 2005-2006 AVALON, MODEL YEAR 2004-2006 HIGHLANDER, MODEL YEAR 2004-2006 LEXUS RX, AND MODEL YEAR 2006 LEXUS GS AND IS VEHICLES. BRAKE FLUID CONTAINING POLYMERS IS USED THAT ACTS AS LUBRICANTS FOR CERTAIN BRAKE SYSTEM COMPONENTS. IF REPLACEMENT BRAKE FLUID IS USED THAT DOES NOT CONTAIN SUCH POLYMERS, OR THAT CONTAINS ONLY SMALL AMOUNTS, A PART OF THE RUBBER SEAL LOCATED AT THE REAR OF THE BRAKE MASTER CYLINDER MAY BECOME DRY, AND THE SEAL MAY CURL DURING MOVEMENT OF THE PISTON. IF THIS OCCURS, A SMALL AMOUNT OF BRAKE FLUID COULD SLOWLY LEAK FROM THE SEAL INTO THE BRAKE BOOSTER.
TOYOTA IS RECALLING CERTAIN MODEL YEAR 2006 THROUGH 2008 LEXUS PASSENGER CARS MANUFACTURED FROM AUGUST 26, 2005 THROUGH AUGUST 4, 2008. MICRO-FOREIGN OBJECTS IN THE MATERIAL OF THE VALVE SPRING MAY DEGRADE THE STRENGTH OF THE VALVE SPRING, POSSIBLY CAUSING THE SPRING TO BREAK.
TOYOTA IS RECALLING 214,570 MY 2006-2008 LEXUS IS, MY 2006-2007 GS AND MY 2007-2008 LS PASSENGER VEHICLES EQUIPPED WITH ALUMINUM FUEL DELIVERY PIPES (FUEL RAILS). ETHANOL FUELS WITH A LOW MOISTURE CONTENT WILL CORRODE THE INTERNAL SURFACE OF THE FUEL RAILS. AS THIS CONDITION PROGRESSES, THE ENGINE MALFUNCTION INDICATOR LIGHT MAY ILLUMINATE.
ON CERTAIN VEHICLES, HIGH STRESS AREAS MAY HAVE BEEN CREATED IN TWO SPECIFIC FUEL PIPES LOCATED IN THE ENGINE COMPARTMENT. COMBINED WITH OTHER FACTORS SUCH AS THE PRESENCE OF CORROSIVE AGENTS IN FUEL, A CRACK MAY FORM OVER TIME LEADING TO FUEL LEAKAGE FROM THE FUEL LINE(S).
ON CERTAIN PASSENGER VEHICLES, IF THE FRONT SEAT BELT RETRACTORS (BOTH DRIVER AND FRONT PASSENGER) BECOME LOCKED, THEY MAY NOT RELEASE DUE TO A COMPONENT OF THE EMERGENCY LOCKING SYSTEM. IF THE SEAT BELT IS LOCKED IN THIS CONDITION, THE OCCUPANT MAY NOT BE ABLE TO PROPERLY FASTEN THE SEAT BELT.
ON CERTAIN VEHICLES, DUE TO IMPROPER ASSEMBLY OF THE AIR BAG INFLATOR, WHICH IS USED IN THE SIDE AIR BAG, THE CURTAIN SHIELD AIR BAG, AND THE KNEE AIR BAG ASSEMBLY, SOME INFLATORS WERE PRODUCED WITH AN INSUFFICIENT AMOUNT OF THE HEATING AGENTS NECESSARY FOR PROPER AIR BAG DEPLOYMENT. IN THIS CONDITION, THE EXPANSION FORCE OF THE GAS MAY BE INSUFFICIENT TO PROPERLY INFLATE THE AIR BAG WHEN THE SRS SYSTEM IS ACTIVATED DURING A CRASH.
