The 1991 Toyota Previa has 3 recalls, the most serious being a potential short circuit inside the radio that can start a fire in the passenger compartment.
The windshield wiper system is the subject of the remaining recalls. Certain wiper components lack the strength to handle high operating loads and can fail outright, leaving the wipers completely inoperative during rain or snow. With no wiper function, the driver has little to no forward visibility in wet weather, which raises the risk of a crash. Prior repair attempts did not fully resolve this issue, which is why it appears across more than one recall filing.
