Most vehicle recalls used to happen only after long, drawn-out government inquiries had identified safety defects and required the car companies to fix them. But in the wake of Toyota's extensive recalls, automakers are initiating more themselves rather than waiting for government regulators to step in. The new mind-set has produced a flood of recalls, some occurring in reaction to just a few complaints from car owners, or maybe only one. The numbers underscore the sudden shift. Two times as many cars and trucks have been recalled in the last 12 months than have been sold, although many of the recalled cars were from previous years. More than 22.4 million recall notices were sent to consumers in that period, including 10 million from Toyota and 428 from the luxury sports car-maker Lamborghini. By comparison, the industry has sold a little more than 11 million new cars and trucks in that time. Industry analysts say that automakers in general are less insistent on disputing the need for a recall and more aware of the harmful publicity that results from not addressing a safety problem quickly. 'Now they're erring on the side of doing a recall, versus not doing a recall,' said Clarence Ditlow, executive director of the Center for Auto Safety, a nonprofit consumer advocacy group. 'All the manufacturers want to clean up their act and get defects and recalls behind them so the public doesn't question the safety of their vehicles.' Federal regulators have also stepped up their oversight efforts since Toyota's sudden-acceleration recalls. Overall, the auto industry is on pace to recall more vehicles in 2010 than in any year since 2004, when a record 30.8 million vehicles were found to have defects. The 2010 numbers do not include most of the vehicles covered by Toyota's two big recalls because the first began in late 2009. In addition, Ford expanded the largest recall in its history late last year, adding 4.5 million vehicles to an already long list of older models with faulty cruise-control deactivation switches. From November through January, Toyota recalled more than 8 million vehicles worldwide -- 6 million of which are in the United States and included in the government data -- in connection with reports of sudden acceleration. In some cases, Toyota said floor mats could interfere with the accelerator pedal, while in others the pedal itself was found to be defective. Some vehicles are covered by both recalls, and as a result are counted twice. In April, the National Highway Traffic Safety Administration fined Toyota an unprecedented $16.4 million, the maximum allowed by law, for waiting too long to initiate a recall for the flawed pedals.
