The Center for Auto Safety has identified at least 50 complaints alleging stalling while underway.

The Center for Auto Safety has called on Fiat Chrysler Automobiles to recall the Chrysler Pacifica over complaints of engine stalling.

"More than 50 individuals have reported to NHTSA that their 2017 Chrysler Pacifica has lost all motive power without warning," the group wrote in a petition to the National Highway Traffic Safety Administration. "This has left drivers unable to accelerate, decelerate, or utilize power steering."

The complaints suggest the minivans are stalling unexpectedly in a range of conditions, at idle or while underway at speeds from 40-60 mph. Some owners have reported multiple failures within the first few hundred miles, while others claim to have experienced the first shutdown after putting a few thousand miles on the odometer.

"All NHTSA complainants report that neither their local Chrysler service department nor any Fiat Chrysler Automobiles (FCA) engineers have been able to replicate this critical malfunction," the petition adds.

If the NHTSA does consider an investigation, the potential vehicle population is expected to be around 150,000 units.
