Service bulletins for the 2012 Toyota Tacoma

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-SB-0047-162018-07-02. Service bulletin. EQUIPMENT; EQUIPMENT ADAPTIVE/MOBILITY. TSB: The breather plug should be replaced during any differential/transfer case repairs to prevent possible repeat failures. The subsequent use of the original breather plug after a repair has been found to contribute to the failure of the differential/transfer case components.

T-SB-0044-162018-07-02. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; STRUCTURE. TSB: On some vehicles, when Rapgard? is removed, the paint may have a stained appearance. These stains appear to be under the clear coat (repainting this area is not necessary). The stain patterns are usually under wrinkles in the Rapgard?. These wrinkles sometimes trap water and cause the paint to stain from the trapped moisture, especially on horizontal surfaces, such as the hood, roof, and trunk. Stains can be removed by heating the stained surface to remove the trapped moisture.
T-SB-0040-182018-06-18. Service bulletin. STRUCTURE:BODY:BUMPERS. TSB: Referencing this Service Bulletin provides best practice procedures when reassembling and installing the front shock absorber with coil spring. Some 2005 - 2015 model year Tacoma vehicles with applicable VDS have a different coil spring diameter. This may lead to a lateral force applied to the support plate upon reassembly of the front shock absorber with coil spring assembly. This may cause the inner rubber sleeve of the support plate to pull out when spring tension is released and the support plate to tilt. NOTE This Service Bulletin ONLY provides best practices for front shock absorber with coil spring assembly. The Repair Manual MUST be referenced with this bulletin when performing front shock absorber with coil spring assembly replacement.
