| Investigations Summary: | The office of defects investigation (odi) has received 40 complaints alleging incidents of stall/loss of motive power, potentially due to transmission malfunction, in certain model year (my) 2019 through 2021 Chrysler pacifica plug-in hybrid electric vehicles (phevs). An odi review of received complaints noted that most stall/loss of motive power incident allegations occurred at speeds greater than 25 mph and resulted in disablement of the vehicle. Beginning in late 2021, odi noted a significant increase in reports alleging loss of motive power involving newer model year Chrysler pacifica phevs. The received reports indicated a loss of motive power could occur at highway speeds and require the vehicle to be towed. Notably, the loss of motive power was often accompanied by a dashboard screen message indicating a charging fault. A review of related vehicle data showed that the malfunction was correlated with a specific internal transmission fault. Odi is opening this investigation to further assess the scope, frequency, root cause, and potential safety-related consequences of the alleged defect leading to stall/loss of motive power on 2019-2021my Chrysler pacifica phevs. The odi reports cited above can be viewed on NHTSA.
