The 2007 Toyota Yaris has 5 recalls, the most serious being a passenger-side front airbag inflator that can rupture and send metal fragments into the cabin, posing a risk of serious injury or death.
The airbag inflator issue has been the subject of multiple recall filings covering vehicles in high-humidity regions as well as broader nationwide populations, but the core danger is the same across all of them: the inflator can explode rather than deploy cleanly, turning the airbag module itself into a hazard for anyone in the passenger seat. Prior repair attempts did not fully resolve the issue for all affected vehicles, which is why multiple campaigns exist for the same defect.
On the electrical side, the power window master switch can develop a short circuit when moisture and debris get past dried-out lubricant on the sliding contacts inside the switch. When this happens, the switch assembly can overheat and melt, raising the risk of a fire that starts inside the door panel.
The remaining recall involves the front seat rails on both the driver and passenger sides. Springs inside the seat rail mechanism can break and cause the seat to lose its locked position. In a crash, a seat that is not locked in place can slide forward or rearward, which means the seatbelt and headrest no longer do their jobs correctly and the occupant faces a greater risk of injury. On three-door models, this affects the front passenger seat rails as well as the driver's seat.
