Summary

The 2019 Chevrolet LCF 5500XD, while a capable work truck, can present several common issues. Engine problems, particularly with the diesel engine, such as fuel injector and DPF failures, can be costly to repair. Transmission issues, whether related to the torque converter or shift solenoids, are also common and can disrupt operation. Electrical problems, stemming from wiring harness or BCM issues, and cab corrosion are also concerns. Interior issues such as the HVAC blower motor, while less severe, can still be inconvenient. The severity and cost of these repairs can range from a few hundred dollars to several thousand, depending on the specific problem and the extent of the damage.
