Condition
Toyota has received a number of reports regarding sliding door front lock assemblies on certain 2011 – 2016 model
year Sienna vehicles. In these reports, during the closing operation of the left and/or right side sliding door, the door
would not completely close and latch due to corrosion on the latch lever pin of the door’s front lock assembly.
Although the sliding door front lock assemblies are covered by Toyota’s New Vehicle Limited Warranty for 3 years or
36,000 miles (whichever comes first), we at Toyota care about the customers’ ownership experience. Toyota is now

lock assembly.
