Dear Valued CYBEX Consumer:

CYBEX designs, engineers and tests its products with safety as its number-one priority.  When CYBEX believes that a recall is warranted, it voluntarily takes steps to do so. Based on a robust commitment to safety and continuous product improvement, CYBEX has decided to recall select US versions of infant car seats manufactured between June 6, 2017, and November 1, 2020. 


The webbing strap used in the central front seatbelt adjuster to snugly adjust the shoulder harness straps onto the infant may fray, which can reduce the strength of the seatbelt. An infant seat belt with insufficient strength may not properly restrain the occupant, increasing the risk of injury in a crash.

Affected Models:

Aton Aton 514XXXXXX


Aton 2

Aton 2 515XXXXXX 
Aton 2 SensorSafe 519XXXXXX 
Aton 2 SensorSafe 521XXXXXX 


Aton M

Aton M 518XXXXXX 
Aton M SensorSafe 518XXXXXX
Aton M 519XXXXXX
Aton Q Aton Q 515XXXXXX 
Aton Q 517XXXXXX


Cloud Q

Cloud Q 515XXXXXX
Cloud Q SensorSafe 519XXXXXX
Cloud Q SensorSafe 521XXXXXX 

Date of Manufacture:

Applies only to infant car seats manufactured between June 6, 2017, and November 1, 2020.

The model number and date of manufacture are printed on a label on the bottom of the seat (as shown blow):
