The 1978 Plymouth Horizon has 3 recalls, with two serious issues: on air-conditioned models, a fuel return hose can rub against the A/C hose until it wears through and leaks fuel near hot engine components, creating a fire risk under the hood.
On manual-steering models, the lower steering shaft coupling may not be properly seated on the steering gear shaft and can work loose over time, introducing excessive play in the steering wheel and potentially leading to a loss of steering control. There is also an electrical concern: the alternator field wiring terminals can loosen from engine vibration, breaking the charging circuit and causing a loss of electrical power to the vehicle.
