The U.S. National Highway Traffic Safety Administration said on Monday it opened a recall query covering about 1.2 million Stellantis' Ram trucks over concerns related to the transmission.

The U.S. National Highway Traffic Safety Administration (NHTSA) has opened a recall query into approximately 1.2 million Stellantis (NYSE:STLA) Ram trucks due to concerns related to the brake transmission shift interlock system.

U.S. auto safety regulator National Highway Traffic Safety Administration (NHTSA) said on Monday that it is opening a recall query covering nearly 1.2 million Stellantis NV’s (STLA) Ram trucks. The probe covers Ram 1500,

These Ram trucks were recalled once already, though the NHTSA is concerned that the remedy may have failed after receiving more than a dozen owner reports.

Ranging from the 1500 to the 5500, the issue potentially affecting nearly 1.2 million trucks traces back to two previous recalls by NHTSA.
