Open the full vehicle complaint log (all categories)When coming to a full stop at a red light (or any need to idle at a stop), the car frequently begins to hesitate as if it is about to cut off. I assume it has something to do with the ‘fuel saving feature’ which comes on in the form of a green symbol in the lower left of the odometer display (the engine is still running the AC) . When you start to drive again the car always jerks before moving , on at least 3 occasions it has actually cut off completely and must be restarted (everything goes off) - it is big problem, especially in heavy traffic (horns blaring & angry drivers are encountered) I almost had a car hit me from behind; my car had jerked slightly when I began to accelerate and then shut off completely. It is definitely a dangerous defect. The Dealership emphasizes 93 Octane gas or higher to help with this issue- but I Always use the highest Octane gas I can find ! It has happened VERY often - I dread stopping at red lights and stop signs, one day it will cause an accident.
