Service bulletins for the 2018 Toyota Tundra

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.

K0B_Dealer Packa2019-05-13. Service bulletin. FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING; ELECTRICAL SYSTEM; SERVICE BRAKES, HYDRAULIC; EQUIPMENT. Dealer Package: The involved vehicles are equipped with a Pre-Collision System (PCS) that may automatically apply the brakes if the system detects a potential collision. Due to the mounting of one of the system?s sensors, it is possible for water to enter the sensor. This can lead to PCS deactivation or inadvertent brake activation resulting in limited deceleration for a short duration of time. Please refer to the Owner?s Manual for additional information regarding the PCS system operation.
K0B_Dealer Daily2019-05-13. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT; SUSPENSION. Dealer Daily Message: **Modified Vehicle Handling Process UPDATE** Certain 2018 ? 2019 Model Year Tacoma and Tundra Millimeter Wave Radar Sensor Handling Procedure for Modified Vehicles Some vehicles may have modifications not authorized or approved by Toyota that make it impossible to perform the remedy for this Special Service Campaign. Toyota does not recommend installing aftermarket, non-Toyota authorized parts or accessories or Toyota parts not originally intended for the vehicle model and cannot evaluate how those modifications could affect a vehicle's operation. This is especially true for the PCS system, because it uses a camera and radar device that has an adjustment based on the vehicle?s original suspension design. It is best to restore the vehicle to its original condition prior to the remedy being performed. Any cost to do this is the customer?s responsibility. As a result, at this time, if a vehicle has modifications of the type noted below, Toyota does NOT RECOMMEND the remedy be performed with the vehicle in its current modified condition. Toyota cannot determine how modifications not authorized or evaluated by Toyota can affect the alignment of the PCS sensor. Please advise the owner that the vehicle?s special service campaign status will remain open, and the remedy will be performed FREE OF CHARGE when the vehicle is returned to a condition in which the remedy can be made.

T-SB-0059-182018-12-03. Service bulletin. SERVICE BRAKES; FORWARD COLLISION AVOIDANCE. TSB: All 2016 ? 2018 model year Land Cruiser and 2018 model year Sequoia, Tacoma, and Tundra vehicles are equipped with a Pre-Collision System (PCS), also known as Automatic Emergency Braking (AEB) as part of Toyota Safety Sense. The Pre-Collision System (PCS) defaults its operating mode to ON after each ignition (IG) cycle. In some driving conditions, such as extended off-road use, driving with tire chains in adverse conditions, towing another vehicle, or when your vehicle is being towed, drivers should operate the vehicle with PCS OFF. Drivers may also prefer to maintain this setting after each IG cycle. If this functionality is requested, follow the procedure in this Service Bulletin to disable the PCS mode reset after each IG cycle.
