A/C failure on other 300 years
No other 300 model year has enough reports of A/C failure for a sheet of its own. See every 300 year.
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
Few of these reports name the part that was replaced.

When it happens
Too few of these reports state a mileage to give a range.
Is this a known problem?
The manufacturer has sent NHTSA 4 service bulletins or notices for the 2018 Chrysler 300 that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. 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.
Air Suspension Components Star Parts Catalog has been updated to show individual service parts for the compressor assembly. This will allow service technicians to repair the root cause without over repairing the system.
Flash: HVAC System Enhancement This bulletin involves reprogramming the Heating Ventilation Air Conditioning (HVAC)Module with new software.
ACTUATOR, A/C and Heater Before replacing HVAC actuator, please contact either Thomas Conway (248) 635-7090 or Paul Aquino (248) 854-4819. Engineering is looking to gather infomation on fail mode and customer concern.
A/C Pressure Transducer A/C inoperative and diagnosis leads to pressure transducer. Call Steve Rice at cell (248) 867-0061 before replacing the pressure transducer. If no response in 15 minutes, please proceed with repair.
What owners wrote
“Touch screen on dash is delaminating, and progressively getting worse. This is causing the touch screen to be completely inoperable, and touch screen must be powered off while driving or it will randomly call people, change A/C setting, etc.”

Should you keep driving it?
This page can't tell you that. 0 of 49 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.
