Has your Plymouth been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Plymouth dealer can also check your VIN. Recall repairs are free.

1978 Plymouth HORIZON recalls, newest first

October 15, 1980NHTSA 80V136000425,000 vehicles potentially affected

Electrical system › Alternator/generator/regulator

Summary
The alternator field wiring terminal connections on the involved vehicles may loosen due to vibration, possibly resulting in an open circuit condition. Should this occur, alternator electrical output to support the vehicles electrical loads and the battery charging system would be lost. This would eventually result in obvious malfunctions of various electrical systems (dimming of lights, reduction in radio volume, etc.).
Remedy
Dealer will install an alternator repair kit which includes a new alternator wiring harness as well as new terminals. Dealer will also inspect the vehicle for the presence of a required second alternator ground strap and add one if necessary.

September 18, 1979NHTSA 79V21500031,000 vehicles potentially affected

Steering › Steering wheel/handle bar

Summary
The lower steering shaft coupling on the involved vehicles may have an oversized serration diameter in the attachment area to the steering gear shaft. Since this oversized coupling may not be adequately engaged on the steering gear shaft, the attachment may loosen, resulting in steering free play.
Remedy
The dealer will replace the lower steering shaft coupling assemblies on the involved vehicles with properly machined components. This will be done at no charge.

Fuel system, gasoline › Storage › Tank assembly

Summary
The fuel tanks on the involved vehicles may exhibit fuel leakage when completely filled. This condition was caused by the rear floor carpet fasteners penetrating the top of the fuel tank.
Remedy
The dealer will inspect vehicles for presence of carpet fasteners across the rear seat area. If any fasteners are found, they will be removed, the floor pan holes sealed, and the fuel tank dropped and inspected for nail holes. If holes are found, the fuel tank will be replaced.
