The 2012 Chevrolet Express 3500, while a capable work vehicle, does have some common issues. Engine oil consumption is a recurring theme, particularly with the 4.8L and 6.0L V8s. The Duramax diesel can suffer from fuel injector and turbocharger problems. Transmission issues, like hard shifting and torque converter shudder, also appear. Suspension problems, electrical gremlins, and interior component failures add to the list. The severity of these issues varies, and the cost to repair them can range from relatively inexpensive fixes like blower motor resistors to significant investments for engine or transmission rebuilds. Prospective buyers should carefully inspect the vehicle, review maintenance records, and consider a pre-purchase inspection by a qualified mechanic.
