NHTSA investigating suspension part failures in 2013 Nissan Altimas

U.S. safety regulators are investigating complaints that a suspension part on Nissan Altimas can come loose from the frame due to corrosion.

The probe by the National Highway Traffic Safety Administration covers about 374,000 cars from 2013. The agency says it has four complaints that rear lower control arm assemblies failed. One owner in Seneca Falls, New York, wrote that the problem caused a crash, but didn’t give details. Three complaints allege the part failed while cars were moving.
