Watch out

Faults owners and the press report, and how to spot each one.

• HID headlights going out All years

  Check: Drive with the headlights on for a while and watch for one or both going out, and ask whether bulbs or ballasts have been replaced.

  A published reference reports 28,000 warranty repairs among 216,000 cars with the optional HID headlights, which could shut off without warning. Toyota settled a class action by extending their cover from three years to five, so it has ended. On CarComplaints.com's page for the 2007, an unofficial source, owners report a headlight going out at about 97,650 miles on average, and 25 replaced bulbs. A published reference, owners' reports (unofficial)

• Brake actuator All years

  One source so far

  Check: Watch for brake, ABS or traction warning lights when starting and on a test drive, and ask whether the brake actuator was replaced.

  Toyota's program ZG1 extended cover for the brake actuator, whose internal faults light brake warning lamps, to ten years or 150,000 miles from first use, so on these cars it has ended. Toyota

• Electric water pump All years

  Check: Ask whether recall 12V536000 was done, and watch the temperature and warning lights.

  A scratch made in assembly could let the coil wire in the electric water pump corrode and break, stopping the pump or stalling the hybrid system. Jalopnik adds that the inverter's water pump can fail with age. NHTSA, Jalopnik

• Steering intermediate shaft All years

  Check: Ask whether recalls 06V188000 and 12V537000 were done, and feel for play or clunks in the steering.

  Toyota recalled 2004–2006 cars because the steering shaft and sliding yoke could crack, and 2004–2009 cars because the shaft's splines could be too soft and wear until steering failed. NHTSA

Recalls

Newest first. Ask the seller for proof the work was done, or check the VIN with NHTSA.

• 2004–2009 Recall 12V537000

  The splines on the steering intermediate shaft may not be hard enough, and can wear until the steering fails. NHTSA

• 2004–2009 Recall 12V536000

  A scratch made in assembly can let the coil wire in the electric water pump corrode and break, stopping the pump or stalling the hybrid system. NHTSA

• 2004–2009 Recall 09V388000

  An unsecured or wrong driver's floor mat can trap the accelerator pedal wide open. NHTSA

• 2004–2006 Recall 06V188000

  The power steering intermediate shaft and sliding yoke can crack under large forces, and steering control can be lost. NHTSA

• 2004–2006 Recall 06V096000

  Some side, curtain and knee airbag inflators were made without enough heating agent, so the airbag may not inflate properly in a crash. NHTSA

• 2004 Recall 04V558000

  Deposits can build up inside the brake light switch, and the brake lights can stop working. NHTSA

Checked against NHTSA records on November 2, 2026.
