Service bulletins for the 2014 Lexus GX

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.

Any previous printed versions of this bulletin should be discarded. In the event that a Lexus vehicle becomes submerged in water, many components may be physically damaged. Electrical and electronic components, including wiring harnesses, are particularly susceptible to corrosion and subsequent malfunction. Although any flooding can be damaging, salt water flooding elevates the potential for abnormal conditions and may increase risks due to its highly corrosive and conductive nature. Salt residue also continues to corrode and remain conductive even after a vehicle dries. This bulletin is intended to assist with safe handling and inspection of flood damaged vehicles and to provide basic guidance on likely needed repairs.

L-SB-0143-11 Rev2018-04-02. Service bulletin. SEATS; AIR BAGS:SIDE/WINDOW. Beginning in 1998, Lexus introduced side airbags as optional equipment. Lexus does NOT recommend replacement of original seat covers with non-Lexus leather or other seat cover materials on vehicles due to the following: Seat covers NOT recommended by Lexus may affect side airbag performance, in general or in part, during an accident. Modifications that negatively affect side airbag performance can result in severe occupant injuries. Seat covers are an integral part of this safety system. Replacing fabric seat covers with non-Lexus leather or other seat cover materials may compromise the effectiveness of this safety system. The design of the seat is complex, integrating safety and strength with comfort and luxury. Lexus strongly discourages modifying original equipment seats that have optional side airbags. Additionally, Lexus strongly advises against the installation or use of aftermarket seat covers, which could impair the performance of the side airbags in the event of an accident.
