Model years: 2014

Problem: Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2014 Highlander and Highlander Hybrid vehicles. The affected vehicles may have improper software installed in the air bag electronic control unit (ECU) for the operation of the front passenger seat belt force limiter, and as a result, the force limiter may use the restraint setting designed for small occupants, such as those that weigh approximately 110 pounds, for all occupants regardless of their size. As such, some of these vehicles do not conform to Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."

Risk: In the event of a crash, a larger front passenger seat occupant may not be properly restrained and be at an increased risk of injury.

Fix: Toyota will notify owners, and dealers will install a software update in the air bag electronic control unit, free of charge. The recall began on June 27, 2014. Owners may contact Toyota customer service at 1-800-331-4331.

Model years: 2006, 2007

Problem: Toyota is recalling certain model year 2006-2007 highlander hybrid and lexus rx400h passenger cars manufactured from february 16, 2005, through august 30, 2006. A module inside the inverter module may contain inadequately soldered transistors that during high-load driving, may be damaged by heat caused by the large current. If this occurs, various warning lamps, including the malfunction indicator lamp, slip indicator light, brake system warning light, and master warning light, will be illuminated on the instrument panel.

Risk: The vehicle may enter a fail-safe/limp-home mode that limits the drivability of the vehicle. It is possible that the hybrid system will shut down while the vehicle is being driven, causing the vehicle to stall unexpectedly, increasing the risk of a crash.

Fix: Toyota/lexus mailed an interim owner notification on july 19, 2011 to advise owners of this recall and the fact that they will receive a future notice when parts become available to complete repairs. Toyota dealers will inspect the hybrid inverter production number to determine whether the inverter contains suspect transistors and replace the module free of charge. Owners may contact toyota at 1-800-331-4331.
