The Altima sedans are from the from the 2012 and 2013 model years and were made at the Nissan plant in Canton, Miss., from May 10 to July 26, Nissan North America told the National Highway Traffic Safety Administration.
"Some of the subject vehicles may have been manufactured with four transverse link bolts and two power steering rack bolts that were not torqued to the proper specification," Nissan told regulators in a letter NHTSA showed on its website.
As a result, the bolts may shake loose during driving, the letter states, and drivers may notice rattling noise.
There was no mention of any injuries or crashes as a result of this issue on the NHTSA website.
Through September, in the U.S. market, 27 percent of the vehicles Nissan sold were Altima sedans.
Altima sales through September were up 17 percent from last year, at 234,040.
Altima owners will be asked to bring their cars into Nissan dealerships, where the bolts will be torqued to the proper specification, NHTSA said. The cars are under warranty protection.
"Based on engineering judgment, it was determined that if a loose bolt falls out completely, the driver may experience difficulty in controlling the direction of the vehicle," Nissan told NHTSA.
Nissan said that on July 26, the last day the vehicles involved in the recall were produced with the potential problem at the Canton plant, workers noticed the issue during a routine test.
On September 21, Nissan confirmed that some of the subject vehicles were at its dealers. On October 3, it decided a safety defect existed and a recall would be conducted.
Owners will begin to be notified on October 29, Nissan told NHTSA.
