2018 WRX AC Compressor Recall – What You Need to Know
If you own a 2018 WRX, it's important to be aware of the AC compressor recall that has recently been announced. In this article, we will discuss the recall, signs of a bad AC compressor, and steps you can take to address the issue.
Understanding the AC Compressor Recall
The National Highway Traffic Safety Administration (NHTSA) has issued a product campaign bulletin regarding the AC compressor on the 2018 WRX. This bulletin announces a design change to the A/C condenser receiver-dryer assembly, involving the addition of a rubber end cap. The purpose of this design change is to address potential issues with the compressor.
It's important to note that Subaru does not manufacture the AC compressor itself. It is sourced from a third-party supplier. While the compressor is not subject to a recall, there have been reports of related issues that may require repair. Therefore, it is crucial to stay informed and take necessary actions in case of any problem.
What the Recall Covers
The recall specifically addresses the A/C condenser receiver‑dryer assembly. Subaru dealers will install a rubber end cap to prevent moisture intrusion that can degrade compressor performance. The repair is performed at no cost to the owner and typically takes less than an hour. As of 2026, the recall campaign has been completed, but owners should still verify status because some vehicles may have missed the original notification window. For the official recall details, see the NHTSA recall database here.
In practice, a common mistake is assuming the compressor itself is replaced; the fix is limited to the receiver‑dryer assembly. If you experience warm‑air symptoms after the repair, you may want to diagnose warm‑air symptoms to rule out other causes.

Signs of a Bad AC Compressor
If you suspect that your WRX's AC compressor is going bad, there are several signs you can look out for:
Odd Sounds: Strange noises when you turn on your vehicle's air conditioner may indicate a faulty compressor.
Hot Air: If cold air is not coming through the vents when you activate the AC, it could be a sign that the compressor is malfunctioning.
Fluid Leaks: Any leakage of refrigerant fluid is a clear indication of a compressor issue.
Stuck Clutch: If the AC compressor clutch remains engaged or disengaged when it shouldn't, it may signify a faulty compressor.
If you observe any of these signs, it is recommended to have your AC system inspected by a qualified technician to determine the exact problem.
Common Misdiagnoses and Next Steps
A refrigerant leak can mimic compressor failure, and a clogged condenser can produce the same hot‑air symptom. Before authorizing a compressor replacement, ask the technician to check condenser performance and verify system pressures. This step often saves unnecessary parts expense.

Owner Reports and Real‑World Experience
Many 2018 WRX owners on enthusiast forums report that the rubber end‑cap installation eliminated the intermittent “click‑click” noise from the compressor clutch. A few noted that after the fix, the AC still blew warm air until they also cleaned the condenser fins — a reminder that the recall addresses only one failure path. If you hear a new noise after the repair, ask the dealer to compare system types to ensure no unrelated HVAC issue is present.
