2016 Silverado 1500 · Defroster/defogger/HVAC system › Rear window · 38,000 miles · Jan 2023

A/C unit does not work. Recharge the system and it leaks out. GM/Chevrolet knows of the issue and has recalled other models using the same equipment. Not on the Chevrolet Silverado models. No mention of leaks or issues by the dealership during regular maintenance. On June 20th 2020 I paid to have the system recharged, didnt blow really cold but gradually it got warmer, now it blows hot air. Last fall oct 2019 it was not blowing cold air, in February 15 2920 while driving the air seemed to get warmer, could not keep the cab cool. After reviewing recall information and other reviews of issues I see that the $1,100 or more for replacement of certain equipment, plus the long delay because GM/Chevrolet has a shortage of the specific parts (back ordered). I think this should be a recall to force GM/ Chevrolet to fix this issue they have known about since before my truck was even built.
