Vehicle stalls from time to time. Very disconcerting when entering a line of traffic. Dealership could not repeat the problem as it's intermittent. There is a vague feeling of impending trouble based on this defect. It was looked for at the first oil change & not found. I have another appt. set up after the second oil change. I'm not holding my breath but at least if I get in a smash up, I'll have it in writing at two different dates.
