Final NHTSA complaint vehicle information * year: 2026 * make: Jeep * model: Grand Cherokee * trim: limited reserve * engine: hurricane four-cylinder * VIN: [xxx] * current mileage: 1,199 miles * incident mileage: 1,181 miles * incident location: parking lot in [xxx] * manufacturer case number: xxx * dealerships involved: sarasota Jeep and venice Jeep complaint title bucking, jerking, rough running, unexpected forward movement, and stalling in reverse complaint description I am reporting a possible safety defect involving my 2026 Jeep Grand Cherokee limited reserve equipped with the hurricane four-cylinder engine, VIN [xxx]. The vehicle repeatedly bucks and jerks during acceleration, including at approximately 5 mph in parking lots. It also runs roughly and has demonstrated unexpected forward movement. These problems affect the vehicle’s ability to accelerate and operate smoothly and may create a safety risk near pedestrians, parked vehicles, other objects, and surrounding traffic. On xxx, at approximately 4:49 p. M. , in a parking lot in [xxx], and with the vehicle at approximately 1,181 miles, I shifted the vehicle into reverse. The Jeep shook severely and stalled. After I restarted the Jeep, it ran very roughly, continued bucking, and jumped forward unexpectedly. This created a potential risk of striking another vehicle, pedestrian, or object in the parking lot. The vehicle also continues to buck and jerk at approximately 5 mph in parking lots, creating an additional risk of unexpected movement near pedestrians, parked vehicles, and other obstacles. On xxx, at approximately 6:22 p. M. , I contacted Jeep customer care and reported that the vehicle had stalled when I shifted into reverse and that it ran very roughly after restarting. The manufacturer case number is xxx. I previously reported the bucking and jerking condition to Jeep dealerships. A service advisor at sarasota Jeep stated information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
I purchased a new 2026 Jeep Grand Cherokee summit equipped with the new 2. 0l hurricane 4 turbo. The vehicle has a repeatable and potentially dangerous accelerator-response problem. From a complete stop, I can apply substantial/full accelerator input and the vehicle initially provides little or no expected acceleration. The vehicle may begin creeping forward and the tachometer may begin moving, but there is little corresponding engine sound or vehicle acceleration. After approximately two seconds, the vehicle begins responding and accelerating however it is still extremely sluggish and dangerous. The condition has been repeatedly reproduced in both normal and sport modes. I have also experienced delayed rpm increase and delayed transmission response/downshift while already moving. The condition has occurred when attempting to enter traffic and creates a safety concern because the vehicle does not immediately respond as expected to accelerator input. The dealership initially told me the vehicle was operating normally based on diagnostic readings amd that because of the computers and software there is no direct throttle response on these drive by wire vehicles anymore. That is simply intrue. The dealership subsequently had the shop foreman test drive with me in the vehicle. The foreman experienced the condition and agreed there was an issue with the lack of throttle response. I repeated the issue multiple times from stop, ehile turning, and at speed. The dealership is now involving a technical advisor. The dealer has told me that a stellantis service bulletin concerning similar drivability symptoms does not apply to my VIN. I am not alleging that the bulletin applies to my vehicle. I am reporting the actual safety-related behavior because I believe it warrants investigation regardless of whether my VIN is currently included in that service action.
Heavy vibration of entire vehicle when in reverse. Occasional lack of power when accelerating. Issues with the transmission occasionally failing to shift gears.
