2017 Chevrolet LCF 4500

The 2017 Chevrolet LCF 4500 is a low cab forward (LCF) truck designed for commercial applications. Engine options include the 5.7L Vortec V8 gasoline engine and the 5.2L 4HK1-TC diesel engine. The 5.2L diesel produced approximately 215 horsepower and 452 lb-ft of torque. It is important to note that most LCF 4500 trucks are upfitted with specialized bodies, so the opinions on the cab and chassis alone can be limited. Some owners like the maneuverability and visibility afforded by the LCF design, while others find the cab cramped and the ride harsh. General dislikes include the limited engine power for heavier loads and the sometimes difficult access to certain engine components for maintenance.

Engine

5.2L 4HK1-TC Diesel

• DPF (Diesel Particulate Filter) Regeneration Issues
  • Description/Symptoms: Frequent DPF regeneration cycles, incomplete regeneration, “Check Engine” light illumination, reduced engine power, and potential for DPF clogging. This can be caused by excessive idling, short trips, or a faulty regeneration system.
  • Solution: Forced DPF regeneration (performed by a technician), replacement of the DPF, or addressing underlying issues causing excessive soot production (e.g., faulty injectors).
  • Estimated Cost to Fix: $500 - $3,000+
  • Recalls: None Found
• Fuel Injector Failure
  • Description/Symptoms: Rough idling, misfires, reduced power, poor fuel economy, and “Check Engine” light.
  • Solution: Replacement of the faulty fuel injector(s).
  • Estimated Cost to Fix: $300 - $800+ per injector
  • Recalls: None Found

5.7L Vortec V8

Summary

The 2017 Chevrolet LCF 4500 presents a range of potential issues, varying in severity and cost. The most significant problems revolve around the diesel engine, particularly the DPF system, which can be expensive to repair if neglected. Fuel injector problems can also be fairly expensive. The Aisin transmission can be a source of issues, but these are typically less severe than major engine repairs. Suspension issues, electrical problems, and rust are all common issues that can lead to more expensive repairs if left alone. Buyers should pay close attention to the engine condition, maintenance records, and any signs of excessive wear or rust.
