A staggering 53.1 million vehicles were recalled in the US in 2016. According to Automotive News, citing a study by AlixPartners (PDF), this resulted in $22.1 billion in claims and warranty accruals by automakers and suppliers, a 26 percent increase over the previous year.
That 53.1 million number represents a 4.5 percent increase over the 50.8 million vehicles recalled in 2015, making 2016 the highest year on record. But remember, 2016 was also the year of Takata's massive airbag recall, as well as General Motors' infamous ignition switch fiasco, both of which accounted for around 23 million vehicles.
As in-car tech has become a bigger and bigger focus for automakers, those components have been the subject of more and more recalls in the past several years. Automotive News says recalls of electronics and electrical systems have risen 30 percent each year since 2013, whereas for a period of years before that, this annual increase rate was about 5 percent.
The big reason comes down to globalization of platforms and technologies. Without local variation in vehicle content, when something goes wrong, it can be a more widespread issue.
"As the number of vehicles using similar systems increases, so do the number of issues detected since the larger production volumes attract closer observation. As a result, recall notices are increasingly likely to involve not thousands but millions of vehicles," the AlixPartners study says.
The study, "The Auto Industry's Growing Recall Problem -- and How to Fix It" (PDF), suggests that automakers and suppliers have cut as much as 50 percent of quality control spending in recent years, directly leading to the larger number of recalls.
