Summary Verdict
The 2020 GMC Savana 4500 demonstrates good overall reliability, particularly for its core mechanical components. The gasoline 6.0L V8 engine and the standard transmission generally perform without significant widespread issues. However, the optional 6.6L Duramax Diesel engine has seen some reports of fuel injector and EGR system problems, which are common concerns for diesel powertrains and can be costly to repair. Electrical issues, such as alternator failure, are also noted but are not excessively prevalent. For fleet operators and owners prioritizing dependability, the Savana 4500 is a capable choice, with potential issues primarily concentrated in the diesel powertrain and standard electrical components, which are generally repairable.
