A baby car seat product that poses a risk of injuries to children because of a malfunctioning safety indicator has been recalled by its manufacturer.

Maxi-Cosi is recalling all of its FamilyFix Slide Pro bases from buyers, information on the Office for Product Safety and Standards (OPSS) website showed.

The baby car seat could detach from the base as a result of the malfunctioning indicator, and users are advised to “stop using the product immediately”, according to the recall alert.

“The product presents a risk of injuries because the indicator, which shows whether the seat is correctly fitted, may display ‘green’ even when the car seat is not fully attached to the base,” the alert said.

“As a result, a user may believe the seat is properly connected when it is not. This could cause the seat to move or detach, potentially injuring the occupant.”

The product does not meet the requirements of the General Product Safety Regulations 2005, according to the OPSS.

Maxi-Cosi is recalling products manufactured in China between 6 September 2025 and 24 March 2026.

A statement on the company’s website reads: “Your child’s safety drives every decision we make at Maxi-Cosi, and in keeping with our deep dedication to you and your family, we want to make you aware of a voluntary recall affecting your product.

“During a recent user test conducted as part of our continuous improvement efforts to enhance ease of use, we identified a potential misuse scenario involving a visual indicator on our new Maxi-Cosi FamilyFix base.

“We have initiated a voluntary product recall as part of our ongoing commitment to the highest possible standards of child safety, product quality, and ease of use.”

Users are urged to check their product by entering the product model reference and manufacturing date on the Maxi-Cosi website. This reference number should contain 10 digits.

The manufacturing date can be found on the white label on the underside of the base, the company said.

Sue Davies, Which? head of consumer protection policy, said: “It is incredibly concerning that Maxi-Cosi is recalling this car seat base due to a risk that it could cause the seat to move or detach during use.

“Anyone with a Maxi-Cosi car seat can use the brand’s online tool to check if their car seat is affected, and if so, they should stop using it immediately.

“Max-Cosi and its suppliers must urgently investigate how this has happened and ensure the necessary safeguards are in place to prevent potentially unsafe products from reaching consumers in future.”
