The 1978 Plymouth Volare has two recalls, the more serious affecting vehicles with tilt steering columns, where a roll pin in the steering shaft coupling can loosen and cause a complete loss of steering control.
The second recall is a compliance issue: certain vehicles were built with ignition timing settings that do not work correctly with the installed spark control computer, causing exhaust emissions to exceed the allowed standard.
