In the July 1978 issue, "Consumer Reports" rated the Dodge Omni/Plymouth Horizon automobile "not acceptable", the first car it had judged such since the AMC Ambassador in 1968. In its testing they found the possibility of these models' developing an oscillatory yaw as a result of a sudden violent input to the steering; the manufacturer claimed: "Some do, some don't" show this behavior, but it has no "validity in the real world of driving". Nevertheless, the next year, these models included a lighter weight steering wheel rim and a steering damper, and "Consumer Reports" reported that the previous instability was no longer present.
