From the factory this vehicle uses OE oil filter 05281090AB. Note the factory fuel filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs every 60,000 mi; coolant every 7,500 mi. The big-interval services (every 7,500 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

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

The 1992 Jeep Comanche represents the low point in complaints for this generation, with only 2 complaints filed that year—down substantially from 14 in 1990 and 6 in 1991—while recalls dropped from 2 to 0 across the same period. This downward trend suggests improving reliability or owner satisfaction as the model matured, with the 1992 model having no recorded recalls and only 9 technical service bulletins versus 10 in prior years. The top complaint areas centered on parking brake and hydraulic service brake systems (one complaint each), with just one crash-related complaint and no fire complaints recorded. Given this trajectory, the 1992 model year appears to be the most problem-free of the three-year span examined, making it the strongest candidate within this generation for a used purchase.
