Recalls for the 2020 Toyota Corolla: 3
A short circuit may develop in the Occupant Classification System (OCS) sensor, preventing the front passenger air bag from deploying. An air bag that does not deploy during a crash increases the risk of injury.
The low-pressure fuel pump inside the fuel tank may fail. If the fuel pump fails, the engine can stall while driving, increasing the risk of a crash.
The seat belt webbing sensor locking mechanism may not lock as intended. In the event of a crash involving multiple impacts, the seat belt may not properly restrain the occupant, increasing the risk of injury.
A recall may cover only some cars of a model year; the campaign size counts every model and year it lists. Enter your VIN at nhtsa.gov/recalls: dealers fix open recalls free.
