Service bulletins for the 2004 Toyota Sienna

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.

ESS_Dealer Daily2018-04-23. Service bulletin. TIRES:TEMPORARY/EMERGENCY SPARE TIRE; EQUIPMENT. Dealer Daily: Toyota has received reports indicating that some vehicles may experience spare tire carrier or carrier cable corrosion even after being inspected and/or repaired as part of a previous Special Service Campaign. During normal usage, water splashing rearward can reach the spare tire carrier due to variation in the placement of the foam splash guard or loss of the splash guard. If the splashed water contains high concentrations of road salt, corrosion of the spare tire carrier and the carrier cable may result. In limited instances, the spare tire may become seperated from the spare tire carrier and create a road hazard that could cause a vehicle crash. Toyota has revised the inspection and remedy procedures for this special service campaign. All owners of affected vehicles in Warm Climate States are now eligible for an inspection of the spare tire carrier assembly and cable.

T-SB-0122-11 Rev2018-04-02. Service bulletin. AIR BAGS; SEATS; EQUIPMENT. Beginning in 1998, Toyota introduced side airbags as optional equipment. Toyota does NOT recommend replacement of original seat covers with non-Toyota leather or other seat cover materials on vehicles due to the following: Seat covers NOT recommended by Toyota 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-Toyota 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. Toyota strongly discourages modifying original equipment seats that have optional side airbags. Additionally, Toyota 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.
