2019 Honda CR-V · Heating & air conditioning
A/C compressor shaft seal leak
Warm air that worsens over time is one pattern Honda connects to a compressor shaft-seal leak on eligible 1.5T vehicles.
What the reviewed source says
Start with the documented condition, not a parts guess.
Honda published a warranty extension for the air conditioning compressor shaft seal on certain 2017 to 2022 CR-V 1.5T vehicles. Eligibility is checked by VIN. Refrigerant loss has several possible causes, so the official inspection procedure is needed before parts are replaced.

Manufacturer position
What the official procedure directs
The dealer inspects the system and replaces the compressor shaft seal when the bulletin procedure and VIN eligibility apply.
Honda's published extension describes time based coverage without a mileage limitation, but the individual VIN still needs to qualify.

Repair paths and safe checks
Separate the diagnosis from the action.
VIN check and seal inspection
Ask a Honda dealer to check VIN eligibility and inspect the compressor shaft seal under Service Bulletin 23-040 before authorizing broader A/C work.
The refrigerant circuit is pressurized and is not an appropriate DIY repair.

Separate poor airflow from warm air
Check whether airflow is weak or whether airflow is strong but warm. A blocked cabin filter can reduce airflow, while a refrigerant leak usually affects cooling temperature.

These guides explain the safety and evidence checks that apply to this problem file.
Bulletin, recall or warranty?
Three official looking documents can describe the same bad part while creating very different rights. The document number, VIN scope and remedy language matter more than what someone called it at the service counter.
Read guide ↗A/C blows warm
Warm vents do not identify the failed part. A few parked observations can stop a blind recharge and point the shop toward the correct circuit.
