As a result, NHTSA has determined that the current evidence does not justify further regulatory action at this time. However, the agency emphasized that this decision does not indicate an absence of a safety-related defect. NHTSA will continue to monitor the situation closely and remains prepared to revisit the issue if new safety trends emerge.
