Service bulletins for the 2014 Toyota Highlander

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

T-TT-0315-14 Rev2018-04-02. Service bulletin. WHEELS. TT: Chrometec (plastic clad) wheels are being damaged during mounting and dismounting of tires.
T-TT-0424-162018-04-02. Service bulletin. WHEELS:LUGS/NUTS/BOLTS/STUDS. TT: Front Brake Vibration Key Points: * Issue can occur at any time if improper torque is applied on lug nuts * Over time, even one lug nut over or under torqued, can cause a vibration issue * When lug nuts are over torqued, this causes the rotor to have a runout out condition which can lead to brake vibration concerns * Brake vibration issues can occur at parking lot to highway speeds * Brake vibration issues can occur at light to moderate braking * Tightening lug nuts in a star pattern method during the torqueing process will assure that even/equal pressure is applied across the rotor hub surface * Torque sticks/wrenches should be used to apply accurate torque values when tightening * Do Not use impact guns/ratchets to completely run lug nuts up to the wheel surface
T-SB-0149-162018-04-02. Service bulletin. WHEELS; EQUIPMENT. TSB: Some 2014 ? 2016 Highlander/HV vehicles may exhibit a condition where the spare tire cable does NOT fully unwind.

Flash calibration updates can only be applied to the vehicle/ECU combination for which they are intended. ECUs have internal security that will not allow them to be programmed with another ECU?s information.
T-TT-0246-13 Rev2018-04-02. Service bulletin. VISIBILITY; ELECTRICAL SYSTEM. Tech Tip: Tips for writing a DPR (Dealer Product Report) on manufacturing issues for windows and windshields.
T-TT-0262-13 Rev2018-04-02. Service bulletin. ENGINE. Tech Tip: Starting with the 2010 Model Year, Toyota began a gradual transition to the use of synthetic 0w20 viscosity engine oil. There are multiple benefits of this oil including: Reduced friction and wear on engine surfaces, Improved fuel economy, Reduction in waste oil stream (in vehicles approved for 10,000 mile oil change intervals), Reduced maintenance cost (in vehicles approved for 10,000 mile oil change intervals). Due to the improved performance and durability of 0w20 synthetic oil, Toyota has extended the oil change intervals to 10,000 mile for most vehicles that require this oil. With this change, the following should be noted: The 2TR-FE (4Runner/Tacoma) and the 3UR-FBE (Flex Fuel Tundra/Sequoia) are the exceptions to this new change interval program; these engines have not been approved for the 10,000 mile interval at this time. A 5,000 mile oil change interval is still required for these vehicles. Also, the Flex Fuel 3UR-FBE requires a 2,500 mile interval when operated on E85 50% of the time or more. Only Toyota vehicles in which 0w20 oil is mandatory (except for the 2TR-FE & 3UR-FBE Engines) have been approved for extended oil change intervals. Vehicles in which 0w-20 is an option to 5w20 (or 5w30) will continue to require 5,000 mile change intervals, even if 0w20 oil is used. In case of vehicles with 10,000 mile oil change intervals, the 5,000 mile service interval has not been eliminated. The traditional 5,000 mile maintenance procedures (such as tire rotation) will continue to be required, and the fluid levels (including engine oil) will need to be checked and adjusted at this time. If the vehicle operation meets the standard criteria for "Special Operating Conditions" such as: driving off-road, on dirt roads, towing a trailer, making repeated short trips under 32 degrees F, or extensive idling, the engine oil must be replaced at 5,000 mile intervals, regardless of oil used.
