Everything below is an owner-reported complaint submitted to NHTSA about the 2018 Chevrolet G4500, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

From owner reports, verbatim
Last summer (2023) the ABS light would come on when starting the vehicle and stay on until the vehicle warmed up and it would go off. By the fall it just stayed on. Stored my RV for the winter and took it to service dept. this April 2024. They conducted a computer scan and the ABS pump is defective. Similar to the first complaint I read about ABS systems on this site. Vehicle is a 2017 Chev. chassis converted to a Coachman Leprechaun RV in 2018. I am the original owner and vehicle has 30,000 miles on it.
Too few reports in this category for a page of its own — they appear in the full complaint list.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
