According to the National Highway Traffic Safety Administration (NHTSA) nearly 22 million vehicles were recalled in 2013, seven million of which were called because the agency initiated the investigation after consumer complaints. Approximately 24 percent of all vehicles recalled were Toyota models.

Approximately 632 recalls were announced for Toyota and Lexus brand cars and trucks. This is the second year in a row that Toyota has had the largest number of recalls out of all vehicle manufacturers.

Chrysler had the second highest amount of recalls with more than 4.5 million vehicles recalls including their Jeep Grand Cherokee and Liberty models after there was a risk of fires in rear-end accidents.

Honda, Acura, Hyundai, Ford, General Motors and Mercedes recalled more than 7 million vehicles in 2013. However, Mercedes-Benz had the best record and recalled less than 750 vehicles in 2013.

The number of vehicles recalled in 2013 increased by more than one-third compared to 2012. Additionally, in 2013 the largest number of vehicles were recalled for safety vehicles since 2004. In 1966, the federal government began requiring automakers to recalls vehicles for safety defects and since then more than 540 million cars and trucks have been recalled.

Although the NHTSA focuses on vehicle recalls, the agency also called for the recall of 36,000 child restraints last year and 1.4 million tires.
