NHTSA Complaint #11488253 — 2017 CHRYSLER PACIFICA

At low speed, the vehicle will suddenly loose power to the wheels, the engine will then race (causing one to back of the accelerator) and then there is a sudden jerk forward as the powertrain appears to re-engage and normal driving returns. The jerk almost feels like the vehicle has been hit as the driver and passengers' bodies are flung forward. Over the last three years, this problem has occurred at least monthly. When reported to the dealer no diagnostic fault information was found. We are aware of a law suit involving this model vehicle and its crankcase sensor. To our knowledge, our crankcase sensor has not been replaced. Our concern is that the sudden loss of power (and the driver's automatic backing off of the acceleration) could case a vehicle behind us to run into us as the vehicle slows without braking. The power loss often occurs as the vehicle is being accelerated on an entrance ramp or through a corner, but has also occurred during straight line acceleration. The last occurrence was 10/05/2022. The contact has stated that the failure has caused multiple occurrences and almost a rear-ending accident.
