Dealer repaired bank 1, fuel injector 5 and 6 were not working and ignition coil 5 was out. after 400 miles of driving, check engine light popped up and dealer identified that fuel injector for cylinder 2 & 3 are not working causing misfire. Dealer wanted to drop the tank @ my cost of $1500, and after that any parts required, will be extra. On top of that the injector for 2 & 3 will not be covered, which was another $1750. Plus god knows what other issues they identify and slap the bill on me. So, I personally purchased fuel injectors from the dealer and replaced it, to find the care running smoothly as ever.
