A/C failure on other Sierra 1500 years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026.
What this problem usually is
Most A/C complaints start the same way: the fan still blows, but the air coming out of the vents is warm or only a little cool. Some owners get cold air that fades after a while, and others hear a noise from the compressor before it quits. It's rarely a safety problem on its own, which is also why it seldom gets a recall.
What got replaced
Owners who name the part that was replaced mention the condenser (50 reports) and the compressor (12 reports).

When it happens
The middle half of failures fell between 48,000 and 72,100 miles, from the 72 reports that gave a mileage.

Should you keep driving it?
This page can't tell you that. 0 of 83 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
