A/C failure on other Grand Cherokee 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: 2015, 2016, 2017, 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 compressor (5 reports).

Is this a known problem?
The manufacturer has sent NHTSA 6 service bulletins or notices for the 2018 Jeep Grand Cherokee that deal with this problem. Newest first.

Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

“The touch screen, infotainment system began to delaminate over a year ago and started experiencing phantom touches when the radio was on (station changes, playlist changes). This has gotten increasingly worse and the heat, AC, and backup camera now turning on and off, uncontrollably.”

“The A/C evaporator was leaking refrigerant. Have had issues 4 times already and have taken it to the dealership to have it repaired. The aspiration of refrigerant is dangerous. This began after one year of owning the vehicle at 8k miles.”

Should you keep driving it?
This page can't tell you that. 0 of 60 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.
