We purchased a used qx56 with under a 100k miles on it. I did not notice during the test drive any issues with it. After about 4 days I had it on the highway running about 70-75ish and I notice a jerking with it. It does not jerk under a pull or a full coast, but just in between. I had it serviced, changed the engine oil and transmission fluid, it drove better for a day then started doing it again. Has anyone else had this issue and what is the solution? I am about to take it to a transmission shop (we purchased a warranty with it) to have it looked at. It is also supercharged with a stillen stage 2 supercharger, I don't think that has anything to do with the transmission tho. Any help is appreciated!!
