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 2020 Chevrolet Express 2500 recorded 9 complaints in the Power Train category, with each of the other listed categories (Electrical System, Structure, Unknown Or Other,Engine) generating a single complaint. It also generated one crash‑related complaint and no fire‑related complaints. In the historical federal record spanning 1998‑2007, complaint volume and TSB counts fluctuated, reaching a high of 13 complaints and 141 TSBs in 2006 before declining to 7 complaints and 194 TSBs in 2007. The 2020 model falls outside that documented range, so a direct numerical comparison cannot be made. Given the low concentration of complaints and the absence of fire incidents, the 2020 Express 2500 appears to be a reasonable purchase, though buyers should confirm that no outstanding dealer service actions remain.
