Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Federal data from 1990 through 1995 shows the generation began with modest regulatory activity, then spiked sharply in 1993 when complaints surged to 98, recalls doubled to 4, and TSBs tripled to 24. For 1994, complaints fell to 19—well below the 1993 peak—yet recalls remained at 4 and TSBs stayed elevated at 22, even as 1995 saw complaints drop to 4 and recalls halve to 2. This places 1994 in a transitional position where formal actions remain high while new owner reports decline. The data identifies Fuel System and Engine as the top complaint areas for 1994, with two crash-related and two fire-related complaints recorded, though it does not specify root causes. Because 1994 avoids the 1993 complaint surge while still carrying elevated recall and TSB counts, it is a comparatively reasonable year to buy provided all recall campaigns have been completed.
