The 2019 Toyota Sienna is included in NHTSA recall 19V418000, which covers 2011-2019 models with the old-style power door cables. Moisture can corrode the outer cable and cause it to separate, so the door may open unexpectedly while driving, fail to stay latched, or slam closed while entering or exiting. This increases the risk of crash or injury. Toyota repairs the cable free of charge under the recall.
The 2019-2020 Toyota Sienna is affected by NHTSA recall 20V012000, part of the Denso fuel-pump population. The low-pressure fuel pump's internal impeller can deform and stop the pump, causing hesitation, rough running, stalling while driving, or inability to restart. This can lead to loss of motive power and increased crash risk. Toyota replaces the fuel pump assembly free of charge under the recall.
Some 2021-2022 Toyota Sienna hybrids are covered by NHTSA recall 22V651000 for a transmission oil pump assembly that can fail due to weak or broken internal components. The driver may see warning lights or a transmission-malfunction message, and the vehicle can suddenly lose motive power or become unable to drive. This is especially dangerous on the highway. Toyota inspects and replaces the failed transmission pump under the recall at no charge.
