Summary
The Oldsmobile Delta 88 has 5 recalls spanning the 1979-1989 production run, with the most serious being a 1986 model year issue where a lower control arm ball joint stud can loosen, break, and separate from the steering knuckle, causing sudden loss of vehicle control with no warning.
The 1985 model year has a separate suspension concern: certain wire wheel packages were assembled with incorrect wheel nuts that may not hold the wheel securely, allowing a wheel to separate from the vehicle while driving. On 1989 models, a fuel rollover valve may be missing entirely, which means a vehicle that ends up inverted in a crash can spill fuel beyond safe limits, raising the risk of a post-crash fire. Going back to earlier production, 1980 models have a compliance issue with emissions control devices, and 1979 models with 3.8-liter engines may not meet exhaust emissions standards.
