Reliability & federal safety record

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

In the federal record, 1998 shows 23 complaints and 2 recalls, placing it below the 1997 peak of 30 complaints and the 1999 spike of 70 complaints but above the 1995 baseline of 1 complaint. Recalls in 1998 (2) are comparable to 1996 (3) and 1997 (2), indicating no major recall surge relative to its immediate predecessor. The complaint categories for 1998 are led by Tires (6) and Service Brakes, Hydraulic (4), with Structure and Seat Belts each at 3, and it records 2 fire‑related complaints while reporting zero crash complaints. Compared with the surrounding years, 1998 sits in the middle of a complaint rise that peaks in 1999 and then climbs again after 2000, suggesting its risk profile is moderate rather than acute. Consequently, while the 1998 Express is not the most problematic model year, buyers should weigh the modest fire complaints against its lower complaint count relative to later peaks, making it a cautiously acceptable purchase if the fire risk is tolerable.
