Toyota has recalled 3.37 million cars worldwide due to possible defects involving airbags and emissions control units.
The automaker initially said it was recalling 2.87 million cars over a possible fault in emissions control units, but this was soon followed by an announcement late on Tuesday that 1.43 million cars needed repairs over a separate issue involving air bag inflators.
Some of the automaker's gasoline-electric hybrid Prius models contain both of the potential defects, taking the total number of vehicles affected by the recalls to 3.37 million.
Despite the announcement, no injuries have been linked to either issue so far.
Yet the inflator, which was not supplied by troubled maker Takata, could partially inflate and enter the vehicle interior, increasing the risk of injury, Toyota said.
Takata has been embroiled in its own ongoing scandal regarding its airbags which has led to the possibility that 100 million vehicles worldwide may need to be recalled.
It was discovered that the inflators could explode with excessive force and spray metal shrapnel into the vehicle. They have so far been suspected in causing 13 deaths worldwide and more than 100 injuries.
Although some of the vehicles featuring Takata’s faulty airbags are also made by Toyota, the issue is separate from this latest round of recalls.
Toyota also said evaporative fuel emissions control units in models produced from 2006 to 2015 including the Prius, Auris compact hatchback and its popular Corolla models were prone to cracks, which could expand over time and lead to fuel leaks.
Late on Tuesday it recalled Prius models and Lexus CT200h cars made from 2010 to 2012 over airbag inflators that could have a small crack in a weld, which could lead to the separation of the inflator chambers.
