The 1979 Buick Riviera has 3 recalls, the most serious involving front engine mount bracket bolts that can loosen and fall out, potentially causing the engine mount to fail and cutting power to the drive wheels while the vehicle is in motion.
The remaining two recalls are compliance-related. On vehicles equipped with the turbocharged V6 engine, one or more tubes in the engine vacuum harness can become blocked, which causes the engine to lose spark advance and disrupts the exhaust gas recirculation and fuel evaporation systems, resulting in emissions that exceed regulatory limits. There is also a lighting concern: certain vehicles may have been fitted with clear bulbs in the front side marker lamps rather than the required amber bulbs, reducing how visible the front of the vehicle is to other drivers approaching from the side, particularly at night.
