US safety regulator NHTSA criticised over GM ignition switch failures
A Department of Transportation investigation has found the NHTSA failed to spot and act on fatal ignition switch defects in GM vehicles, citing poor management and under-resourcing.
A US Department of Transportation investigation has sharply criticised the National Highway Traffic Safety Administration (NHTSA) for failing to identify and act on General Motors’ defective ignition switches, which have been linked to at least 100 deaths. The report, seen by Reuters, points to ineffective management, inadequate investigation practices and insufficiently trained staff as key reasons the safety regulator missed warning signs for years.
The Department of Transportation’s Office of Inspector General found that NHTSA lacked the ability to collect and interpret critical safety data, struggled to screen the information it did have, and repeatedly failed to hold manufacturers accountable. The agency’s shortcomings were exposed by the GM ignition switch crisis, which led to a massive recall and widespread criticism of both the carmaker and the regulator.
Management and staffing failures
Investigators identified several internal failings at NHTSA. The report described a lack of technical expertise among staff responsible for analysing increasingly complex vehicle electronics. Management was found to be slow to respond to warning signs and reluctant to use regulatory powers, even as complaints mounted. The last significant budget increase for the defect investigations unit was nearly a decade ago, leaving the agency under-resourced as vehicle technology advanced.
Transportation Secretary Anthony Foxx and NHTSA Administrator Mark Rosekind responded by urging Congress to boost the agency’s funding and enforcement powers. Rosekind, who took over the NHTSA less than six months before the report, has since promised stronger oversight and more aggressive use of regulatory tools, including in the ongoing Takata airbag recall.
Implications for safety oversight
The findings have raised questions about the NHTSA’s ability to keep pace with modern vehicle technology and protect public safety. The agency’s handling of the GM ignition switch defect has been cited as a case study in regulatory failure, while the ongoing Takata airbag crisis has further highlighted the need for reform. Calls for increased funding and technical expertise are likely to continue as Congress reviews the agency’s future role.
The GM ignition switch recall remains one of the largest and most controversial in US automotive history. For further detail on the scale of the recall and its impact on GM’s reputation, seeGM Faces Reputation Risk as Ignition Switch Recall Widens.
