The National Highway Traffic Safety Administration (NHTSA), the federal agency within the Department of Transportation responsible for automotive safety, has opened a new investigation looking into a Ram defect that may not have been remedied by a previous recall.

NHTSA has launched a probe into nearly 1.2 million Ram trucks for safety concerns. The models were previously recalled over a brake transmission shift interlock issue. Officials have linked seven reported injuries to multiple post-recall incident reports.
