The 1980 Buick Skylark has 3 recalls, the most serious involving a cracked steering gear mounting plate that can allow the steering connection to loosen, causing the wheel to turn several degrees before the car actually changes direction.
On automatic transmission models, the transmission fluid cooler hoses can fail while driving and leak fluid into the engine compartment, where it can ignite and start a fire. There is also a lighting concern on Skylark Sport trims: an incorrect turn signal flasher causes the blinker to flash too quickly, and if any signal bulb burns out, the indicator light on the dashboard stops working rather than alerting the driver.
