Chevrolet introduced a new transmission, new paint colors, an improved security system, and composite headlights on its 1998 Astro models. The theft deterrent system prevented the van from starting if the correct key was not used. The optional "Dutch" rear doors were popular among owners; split-panel doors sat below a liftgate window. Bucket seats and a lighted entry system were standard on the 1998 Chevy Astro vans.

1998 Chevy Astro owners tend to keep the vehicles for many years and rely on it for hauling and family trips. However, many owners say the 1998 Astros have too little legroom, and numerous mechanical and maintenance problems: rear axle after 130K miles, window controls, fuel pump. Some say the 1998 Astro has poor visibility out the back and cite poor safety ratings in crash tests. One owner said it "eats brakes."
