Common Issues Leading to AMC Recall
Below is a straight-shooting breakdown of real, documented AMC recalls. What failed, why it mattered, and how it was fixed. I grouped them by risk, from “could stall or catch fire” down to “compliance clean-up,” and I've included the official NHTSA campaign numbers (and EPA actions where relevant) so you can verify every line.
Below are some of the reported causes:
Emissions system defect (EPA-ordered recall, 1978)
In May 1978, the U.S. Environmental Protection Agency ordered American Motors Corporation to recall a large group of vehicles, about 270,000 of the 1976 AMC passenger cars plus roughly 40,000 of the 1975–1976 Jeeps and postal trucks, because a faulty back-pressure sensor in the emissions-control system could fail after months of use.
The part (supplied by Eaton) led engines to emit excess nitrogen oxides (NOx) beyond legal limits. EPA officials emphasized the public-health stakes (smog formation; breathing problems, especially in children). AMC had already launched a smaller, voluntary campaign earlier that year; EPA's action expanded it decisively. The remedy at that time is to replace the defective sensor and restore compliance.
Affected models (contemporaneous reports): 1976 AMC passenger cars commonly cited include Hornet, Gremlin, Pacer, and Matador, with additional counts for 1975–1976 Jeeps and mail trucks.
Why this matters: Although it was an emissions (Clean Air Act) action rather than a safety recall under NHTSA, it functioned like one.
Ignition module connector (1978 safety recalls)
This recall was filed around March 1978. A faulty ignition module connector/wiring could interrupt power and stall the engine. About 525,000 AMC cars and Jeeps from 1974–1976, including the Gremlin, Hornet, Matador, and Pacer.
Rear axle recall (1978 safety recalls)
This recall was filed around August 1978, and a public announcement followed in October. Possible rear axle shaft or hub failure that could lead to wheel separation and loss of control. Certain 1977–1978 Jeep J-Series trucks and Wagoneer models. The vehicle count was much lower than the ignition recall.
