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 1998 Bravada lands in a high-complaint phase of this generation: its 110 complaints trail only 1997's 122 among the 1991-1999 model years and sit well above the 1995-1996 and 1999 figures. However, federal severity metrics are comparatively restrained that year, with just 2 recalls and 1 investigation, while manufacturer technical service bulletins nearly doubled from 80 in 1996 to 119 in 1998, suggesting growing dealership-level issues. The leading complaint categories are visibility (28), electrical system (14), steering (9), and suspension (6), with 3 crash-related and 2 fire-related complaints on record. Against the broader arc, 1998 is the calm before the storm: 2002 explodes to 243 complaints, 10 recalls and 10 investigations, while 2003-2004 remain elevated in recalls and TSB volume. That positioning makes 1998 a middling-risk used-vehicle choice—not the worst year of the generation, but not a low-complaint outlier either, and buyers should budget for the visibility, electrical, steering and suspension items reflected in its complaint profile.
