What's wrong?
The refrigerant in the 2022-2023 Mercedes-Benz G 550 and AMG G63 is the fluid the air-conditioning system uses to move heat. In normal operation, the HVAC system circulates that refrigerant through sealed lines so the cabin can be cooled and the defroster or defogger can clear glass when needed.
On affected SUVs, the production process filled the air-conditioning system with the wrong refrigerant for that vehicle. The HVAC system is designed, certified, and documented for a specific refrigerant type. When the filled refrigerant does not match that specification, the system is no longer operating with the fluid Mercedes-Benz intended for its cooling and visibility functions.
The driver will not get a dashboard warning or other clear signal tied to this mismatch. There is no warning sign before failure, so the VIN check is what confirms whether a specific G 550 or AMG G63 is included.
Who's affected?
Spans the G 550 and AMG G63 across the 2022 and 2023 model years, with the same refrigerant component tied to the defroster, defogger, and HVAC system.

A matching year and model does not confirm inclusion. Check your VIN to confirm whether your specific SUV is included.
What's the safety risk?
In a crash, the incorrect refrigerant can leak and increase the risk of a fire. There is no warning sign before this happens, so confirm the recall by VIN and schedule the refrigerant replacement promptly. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2022-2023 Mercedes-Benz AMG G63 or 2023 Mercedes-Benz G 550 is included in this recall.
- Contact your nearest franchised Mercedes-Benz dealer to schedule the free air-conditioning refrigerant replacement.
- Bring the recall notice if Mercedes-Benz mailed one. If not, reference recall number 24V170 and Mercedes-Benz recall 2024030016 when you call.
- Ask the dealer to confirm the refrigerant repair is complete before regular use, since the wrong refrigerant is tied to leak and fire risk in a crash.
- Keep the appointment even if the air conditioning feels normal; the recall is about the refrigerant in the system, not a warning light.
What happens at the repair
At the dealer, a Mercedes-Benz technician removes the incorrect air-conditioning refrigerant and refills the system with the correct refrigerant covered by the recall. The replacement refrigerant and labor are free under the recall. Mercedes-Benz has a reimbursement plan on file for owners who already paid out-of-pocket for the same refrigerant correction before the recall notice. Ask MBUSA customer service or the service desk how to submit repair documentation.
