Technical Service Bulletins
Below, we highlight several key 'hidden' protections you may not be aware of, discovered through service campaigns and technical service bulletins. TSBs highlight common potential problems with models and provide corrective measures to dealerships. The items flagged below are of particular note, indicating a potential risk, and a potential correction, should you experience the specific issue. In some cases, an extended warranty may offer additional protection for a particular at-risk component.

2010-present

This generation has three important recalls:

2010 models were recalled for a cracked brake booster pump accumulator housing and loss of braking power assist (D0H), and some were recalled for an ABS actuator ECU update to improve inconsistent brake feel (A0B).

2010-14 models were recalled for a software update to prevent generator damage during accelerating (E0E).

Service bulletins

2010 models may have a blurry A/C control panel display (387-09); some may leak coolant from the transmission drain plug (352-09); and some might need improved headlamps if they collect condensation, which is covered under the 3-yr/36,000-mile warranty (284-10).

2010-11 models may need updated brake actuator software if there’s noise when the brake is pressed. (363-10), some might need an updated rear engine mount for abnormal vibration or noise below 20-degrees Fahrenheit (204-11), and some need updated rear brake pads for squeaking in cold temperatures (102-11).

2010-12 brake pads may wear unevenly, covered under the 3-yr/36,000-mile warranty (248-12).

2010-14 models may need a revised intake manifold for a check engine light that comes on after start up below 23-degrees Fahrenheit 103-12).

2012-13 models might need an updated compressor if the A/C blows warm air at startup (59-13).

2013-14 models are prone to hybrid battery damage if the cooling fan by the rear doors is blocked; Toyota will cover damage once under the 8-yr/100,000-mile hybrid warranty, but owners must keep it clear of obstructions (270-13).

REDESIGN YEARS 2004 • 2010

2004-09

There are three recalls and two warranty extensions of note:

2004-09 models had the warranty for the instrument cluster extended to 9-yrs/unlimited miles (ZTV).

2004-09 models were recalled for a manufacturing defect to the “hybrid electric water pump” (C0U); and to prevent possible loss of steering ability (C0T) - this was expanded from the original 2004-06 model-year recall in 2006 (60C).

2006-09 models with HID headlamp had the warranty for the headlamp ECU and bulbs extended to 5-yrs/50,000 miles; the bulbs flicker at the end of their lifespan (ZTJ).

Service bulletins

2004 models might need an updated instrument cluster and fuel filler pipe if the fuel gauge is not accurate (10-04); and some have smart key interference with the Mobil Speedpass, so Toyota changed the frequency and updated the system (1-04).

2004-05 models may need improved headlight leveling sensors if there’s a warning light on or flashing (4-06).

2004-07 models that squeak when stopped have a bad brake actuator (307-08).

2004-08 models may need an updated front seat cushion shield to eliminate squeaks (390-08), some need an improved engine mount for abnormal metallic knocking (300-08), an updated evaporator addresses a lingering odor after startup (261-09), and some may need a new coolant heat storage water pump if there’s a squeak during startup or shutdown. (87-08).

2004-09 models might need a new shift lever assembly if it returns to neutral after being put in drive or reverse. (142-11).

2004-10 models may have a loose brake pedal pad that needs to be re-bonded (285-09).

2006-09 models might not shift out of park below 14-degrees Fahrenheit; a newly designed relay fixes this but is only covered under the original 4-yr/50,000-mile warranty (57-09).
