Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 1998 BMW 750iL sits at the top of the federal complaint curve for this generation, with six NHTSA complaints—more than any other model year shown and double the volume of the adjacent 1997 and 1999 entries. However, recalls moved in the opposite direction: 1998 carries just one recall, down sharply from the three-to-four recall levels recorded for 1995 through 1997. Technical service bulletins also eased from the 1997 peak of 17 to 13 in 1998, then fell further to six in 1999, suggesting the 1998 model year was a late-phase refinement point rather than the start of a new problem spike. Reported complaint categories are concentrated in visibility, with smaller counts for air bags/fuel-propulsion, visibility/equipment, and tires; the data record zero crash-related and zero fire-related complaints, though it does not specify root causes. Because 1998 pairs the generation's highest complaint count with relatively low recall exposure and no reported crash or fire incidents, it is a cautiously acceptable year to buy if a thorough pre-purchase inspection specifically addresses the visibility and tire concerns reflected in the federal record.
