1989 Isuzu Pickup

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1989 Pickup.

The 1989 Isuzu Pickup enters the reference record as a vehicle defined by a notably restrained reliability profile, marked by just nine owner complaints and a single recall centered on its top issue area of seat belts. Looking at where this model year sits within the broader complaint history spanning 1992 to 1995, its nine grievances fall well below the peak of twenty-one complaints seen in 1994 and only slightly above the historical low of six in 1993. Consequently, the 1989 model year occupies a favorable position in the vehicle's reliability timeline, meaning researchers can view it as a comparatively stable and trouble-free iteration within the broader lineage.

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 provided year-by-year federal record spans 1992 through 1995 and includes no data for the 1989 model year, leaving the target year outside the available arc with no comparable metrics from adjacent model years. Across that 1992–1995 window, complaints varied from 6 to 21, recalls remained between one and two annually, and both investigations and TSBs stayed in single digits, with 1994 representing the high-water mark at 21 complaints and two investigations. For 1989 specifically, the available data shows four Seat Belts complaints, two Power Train complaints, and one each for Suspension,Structure and Service Brakes, Hydraulic, plus two crash complaints and zero fire complaints, though no root causes are specified. Because the 1989 model lacks any recorded recalls, investigations, or TSBs in the provided dataset, it cannot be trended against the better-documented 1992–1995 period. Given the absence of comprehensive federal tracking for 1989 alongside the limited but present seat belt and crash complaints, this year is a speculative buy that cannot be verified as reliably low-risk based solely on the supplied record.
