Final rule.

This rule is being issued pursuant to the Fixing America's Surface Transportation (FAST) Act, which requires the Secretary of Transportation (Secretary) to extend the period of time manufacturers of motor vehicles, child restraint systems, and tires must retain records concerning malfunctions that may be related to motor vehicle safety under the National Traffic and Motor Vehicle Safety Act (Safety Act). Section 24403 of the FAST Act directs the Secretary to issue a rule increasing the record retention period to not less than 10 years, instead of 5 years, as presently required under the regulatory provisions. Pursuant to its delegated authority, NHTSA is updating its regulations in accordance with this mandate to extend the time that manufacturers are required to retain certain records that may be related to motor vehicle safety to 10 years.
