August 9, we were driving home when the vehicle jerked 2-3 times then the engine shut off (while in motion). This happened on a windy backroad with no way to pull over. We were able to restart the vehicle and make it home safely. Contacted Jeep on the 10, they said it was due to a spark plug recall. When driving to the dealership that morning service AWD light turned on, Jeep replaced the spark plugs and stared that fixed the problem. Driving home once picked up and service AWD light turned on again. Dealership is now stating it is the Drivetrain control module.

Sparl Plug recall on Jeep Grand Cherokee 2026 L Laredo 4x4. While driving my 2026 Jeep Grand Cherokee L Laredo 4x4, the vehicle occasionally jerks/shudders when I shift into Drive and begin moving. The vehicle feels sluggish and does not respond smoothly when accelerating. This has happened even after the vehicle has been running for several minutes. The vehicle is new, and I am concerned that this may be related to a powertrain or transmission problem.

Vehicle is very jerky while transmission is downshifting. With no pressure applied to gas pedal vehicle lurches forward on own forcing me to step on brakes to correct lunging forward. At parking lot speeds and while in reverse vehicle is very sluggish and feels like stalling will occur if pressure is not applied to gas pedal. Vehicle is also sluggish and does not respond right away while entering highway , there is a delay with acceleration , this also could cause an accident as the vehicle is not speeding up correctly.

Vehicle: 2026 Jeep Grand Cherokee L Limited Location: [XXX] Safety Issue Description: When using the remote auto‑start with the key fob, the engine starts briefly and then shuts off. When the vehicle is manually started, the check‑engine light immediately illuminates and begins flashing, and the vehicle jerks violently even while in park. The flashing check‑engine light indicates an active engine misfire, which poses a significant safety risk due to potential engine stalling, sudden loss of power, and potential catalytic‑converter damage.

Two issues- 1. When pulling out into traffic the engine/gas did not catch and we slowly creeped out across lanes before the gas took. This almost caused us to become t-boned by a passing car. When the gas took the car lurched forward fast which could have been another accident. 2. When driving with adaptive cruise control the forward collision warning fault light and service adaptive cruise control light kept turning on and off with a service needed message on the heads up display. This flashed on and off repeatedly causing driver distraction and also limiting vehicle safety. This vehicle has been taken to the dealership multiple times since purchase with various resets done (Transmission control module, powertrain control module) and still numerous panel error lights turn on (engine malfunction light, traffic signal recognition fault light) and issues occur (ac stops blowing cold air, inside screens freeze) but can never be replicated or fault code founds. The biggest safety issue is the lagging engine/gas that randomly occurs from a stop as you can’t predict when it’s going to happen and it will cause an accident at some point.
