What is the cost to repair a fuel injector, and shouldn't the dealership replace all of them because if one is bad aren't the others likely to go bad soon after? I haven't even had the vehicle for 30 days. Ugh! So frustrated.

What is your question?

The vehicle ran great for the first 29 days, then on the 30th day my check engine light came on (started to flash) and it would start shaking and not accelerate. Dealer said it was a fuel injector, which would cost $485 to replace. Does this sound right, or should I make them replace all of them? Wondering if I should give the vehicle back to the dealer and buy something else because the extended warranty doesn't cover this issue?
