Best bet is to take your car for 3S, for EFI new car just don't take risk with roadside mechanics. Plus as I have mentioned earlier too that there are more things for car maintenance rather than just oil and filter change.
At 5k service i was hearing some noise when i apply brakes from front left side tire, it sound like some plastic movement, after service it is gone no noise or sound, I have asked the person at dealership, he said some screws are lose so they tighten them as a regular maintenance check, now there should not be any noise and he was right.
