Suspension components, particularly leaf springs, can show wear under heavy use. Electrical issues like alternator failure and trailer brake controller problems are not uncommon. Interior and exterior components are generally durable, with occasional minor issues like tailgate latches. Overall, the Silverado 2500HD is a dependable truck for its intended purpose, but potential buyers should be aware of the specific issues associated with the diesel engine and heavy-duty components.
