2017 GMC Savana 4500

The 2017 GMC Savana 4500 is a full-size van primarily used for commercial purposes, such as cargo transport, passenger transport (converted buses), and utility work. It’s known for its robust build, large cargo capacity, and relatively simple, easy-to-maintain design. However, it’s often criticized for its dated interior, relatively poor fuel economy compared to more modern vans, and somewhat agricultural driving experience. The 2017 model year Savana 4500 offered several engine options. The most common and well-documented is the 6.0L Vortec V8 producing 342 horsepower and 373 lb-ft of torque. Other engine options include the 4.3L V6 and a 2.8L Duramax diesel. The primary transmission paired with the 6.0L V8 is the 6L90 six-speed automatic.

Summary

The 2017 GMC Savana 4500, while a workhorse known for its utility, can experience several common issues. The most serious and costly problems are related to the 6.0L Vortec V8 engine, specifically AFM lifter failure and oil consumption. Transmission problems, such as torque converter failure, can also be expensive to repair. Suspension and electrical issues, while less severe, can still contribute to maintenance costs. Overall, potential buyers should be aware of these common problems and factor them into their purchasing decision, including a thorough pre-purchase inspection by a qualified mechanic.
