The 1978 Plymouth Horizon has 3 recalls, the most serious being a fire risk on air-conditioned models where a chafing fuel return hose can leak fuel under the hood, and a steering failure on manual-steering models where a loose lower steering shaft coupling can cause the driver to lose steering control.
On the electrical side, alternator field wiring terminals can work loose from engine vibration, breaking the charging circuit and cutting electrical power to the vehicle while driving. This can cause gauges, lights, and other electrical systems to go dark, and the engine may eventually stall once the battery drains.
