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.
