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.

Dealer Letter: 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.
