Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1980 Horizon.
The 1980 Plymouth Horizon enters the reference record as a model year with a notably thin file of owner complaints — just one on record — though that lone grievance centers on the fuel system, gasoline, flagged as this year's top complaint area. Three recalls were issued for the model year, a modest figure that gives researchers a measured sense of manufacturer attention rather than cause for alarm. Taken together, the 1980 Horizon sits at a relatively quiet point in the model's reliability history, where the combination of minimal owner-reported issues and a contained recall count suggests a year that, despite its fuel-system flag, did not generate the volume of problems that would define more troubled model years — making it a comparatively stable data point for anyone tracing the Horizon's overall trajectory.
Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 1980 Plymouth Horizon dominate in one area — the fuel system, gasoline, 1 of 1 reports (100%), well ahead of the next concern. That matters, because the fuel system, gasoline are also the target of recall 80V-139 on this vehicle — so the single most useful check before buying or servicing one is confirming it was actually performed. 0 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the fuel system, gasoline pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
