The National Highway Traffic Safety Administration (NHTSA) has opened a probe into certain Stellantis vehicles over complaints of vehicles losing power, shifting into park, and engaging the emergency brake, reports The Associated Press.
A total of around 150,000 vehicles, comprised of model year 2022 Ram pickup trucks and Jeep Wagoneer SUVs, are covered in the probe. All of these vehicles contain Stellantis’ 5.7-liter Hemi e-Torque mild hybrid system, allowing them to power themselves.
NHTSA first announced the launch of its probe yesterday after receiving 80 complaints from vehicle owners alleging their engines shut down–typically while driving at low speeds. In some cases, the vehicle would not start again afterward.
A recall was issued by Stellantis for around 131,000 Ram pickups and Jeep Wagoneers with the same hybrid system last April.
With the launch of the probe, NHTSA will be seeing what all models are affected by the problem, what’s causing it, and the frequency of it. It may result in the agency issuing a recall.
