Here’s a look at some of the latest recalls and product safety announcements.

Nissan recalls more than 54,000 cars, cites air bag problem

Nissan is recalling more than 54,000 cars because of curtain and seat-mounted air bags that may unexpectedly deploy when the door is slammed.

Nissan North America says the recall affects the 2012 Nissan Versa vehicles. It says the problem may be caused by the degradation of the side impact sensor connector pins. The unexpected deployment of the air bags can increase the risk of injury.

Nissan says dealers will install a new jumper harness and replace the side impact sensors free of charge. Car owners can contact Nissan customer service at 1-800-647-7261 or the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 or visit www.safecar.gov.

Hyundai recalls 978,000 cars; seat belts can come loose

Hyundai is recalling nearly 978,000 cars in the U.S. because the front seat belts could detach in a crash and fail to hold people.

The recall covers Sonata midsize sedans from the 2011 through 2014 model years, and the Sonata hybrid from 2011 through 2015.

Hyundai says in government documents that a fastener for a seat belt anchor may not have been fully latched during assembly. If that happens the belts can detach.

The company says it knows of one minor injury caused by the problem.

The trouble was discovered in September when an owner reported that the front passenger belt in a 2013 Sonata came loose in a collision.

Owners will be notified starting April 7. Dealers will inspect the seat belt anchor system and repair it if needed.

Baby gear injuries surging, often due to falls

Every eight minutes in the U.S., a child under three has an accident related to baby products like strollers, carriers, cribs and walkers, a study suggests.

That adds up to more than 66,000 injuries a year on average, and it only counts infants and toddlers who visit the emergency room. Injuries are on the rise, and roughly four in five are due to falls, researchers report in Pediatrics.

“What’s surprising is how many children are still experiencing nursery product-related injuries serious enough to result in a trip to the emergency department – one every eight minutes,” said senior study author Dr. Gary Smith, director of the Center for Injury Research and Policy at Nationwide Children’s Hospital in Columbus, Ohio.

Concussions and other head injures appear to be driving the surge in emergency room visits, Smith added by email.

2nd child dies in fire linked to exploding hoverboard

Authorities say a second child has died from a fire in Pennsylvania that fire officials blamed on an exploding hoverboard.

The deaths — if definitively linked to the two-wheeled, battery-powered scooter — would be the first in the U.S. caused by a hoverboard fire.

A county coroner told Pennlive.com that 10-year-old Savannah Dominick died Thursday morning from severe burns. Another child died Saturday from the fire that broke out March 10 at a home in Harrisburg, the state capital.

The U.S. Consumer Product Safety Commission says it is working with the fire department to confirm the cause.

It’s also trying to figure out if the make and model is one of the hundreds of thousands the agency has recalled due to fire hazard.

The agency has investigated more than 60 hoverboard-related fires.
