Summary

The 2019 Chevrolet LCF 4500HD can be a reliable workhorse, but it’s not without its potential problems. The most common issues revolve around the emissions system (DPF, EGR) of the Isuzu diesel engine, followed by transmission shift quality and suspension wear. Electrical issues and interior glitches are also reported. The severity and cost of repairs can vary greatly depending on the specific problem. Preventative maintenance, especially regarding the DPF and regular transmission fluid changes, is critical to extending the life of this vehicle. Rust can be a significant issue, particularly in areas with harsh winters, so proactive rust prevention is recommended.
