Summary

The 2018 GMC Savana 2500, while generally reliable, is prone to a few common issues. The most concerning are related to the 6.0L V8 engine’s AFM system and the 6L80 transmission. AFM lifter failures can be costly, and transmission issues can range from minor inconveniences to major repairs. Suspension components such as leaf springs and ball joints can also wear out, especially with heavy use. Electrical issues are relatively uncommon, and interior and exterior issues are generally minor. The cost of repairs can vary widely depending on the specific problem and the extent of the damage, but potential buyers should be aware of these potential issues and factor them into their purchasing decision.
