NHTSA complaint #11746651

Owner complaint summary

Recurring incident after completion of Jeep recall software update 68C intended to address fire hazard associated with the vehicle's hybrid battery. Since that update, when driving in standard Electric mode, the vehicle experiences a sudden loss of power, hesitation, and a physical 'bogging down'. Following this, the vehicle abruptly surges into combustion engine mode, causing a sudden and unpredictable acceleration lurch just after the vehicle has hesitated to accelerate. It poses a hazard for rear-end collision, attempting to pick up speed (e.g., to pass or move from a vulnerable position) and overall maneuvering and operation of the vehicle.
