Summary
The Buick Roadmaster has 6 recalls spanning the 1991-1996 production run, the most serious being a 1996 model year issue where wheel lug nuts may not have been tightened to specification, which can fracture the wheel studs and cause a wheel to separate from the vehicle while driving. The 1995 model year has two separate concerns: lower control arm ball joints that can loosen and separate from the front suspension knuckle, removing steering and handling control, and a transmission shift linkage that can allow the gear selector to move out of Park without the ignition key present, letting the vehicle roll away unattended. On 1994 models, an engine oil cooler inlet hose can contact the steering gear, wear through, and allow oil to drip onto hot engine components and start an engine compartment fire. Going back to the early years of production, 1991 models have a secondary hood latch that can corrode and fail to engage fully, allowing the hood to fly open while driving. There is also a seatbelt concern on 1991 wagons and 1992 sedans where the plastic covering on the shoulder belt guide loop can crack and expose a steel edge that can cut through the belt webbing in a crash, reducing restraint when it matters most.
