The 2013 Toyota Avalon has 3 recalls, the most serious involving the air conditioning drain hose and the optional pre-collision braking system, both of which can cause airbags to deploy unexpectedly or fail to deploy when needed.
A clogged air conditioning drain hose lets water pool inside the condenser unit housing, and that moisture can reach electrical components and cause a short circuit. Depending on the short, the airbags may either deploy without warning during normal driving or become disabled when they are actually needed in a crash. Separately, vehicles equipped with the optional pre-collision system can experience unexpected automatic braking, which raises the risk of a rear-end collision from the vehicle behind. There is also a concern with the airbag control unit itself: during certain crashes, the module can malfunction and fail to trigger the airbags or seat belt pretensioners, leaving occupants without the restraint protection the system is designed to provide.
