I’d classify a fuel injector as part of the powertrain. But the folks who wrote the warranty language might not agree. p0266 does suggest a fuel system problem. Suggest to tell us more about your car. Is it a hybrid, plug in hybrid? If conventional engine, which engine do you have? Ask your shop if a fuel system gasoline treatment, product you add to the gas tank, might be a good place to start.
To determine if it’s covered, you need to have the dealer determine what the problem is. Then they will discuss it with Hyundai corporate and they will determine if it’s covered. If it’s covered, you will not be charged a diagnostic fee. If you delay, it will go out of warrant an it definitely won’t be covered.
Fuel injectors are covered by the emissions warranty for 5 years/60,000 miles. A warranty booklet should have been included with your owner’s manual.
For PZEV certified vehicles registered in California and other select states, the fuel injectors are covered for 15 years/150,000 miles.
Why ask google when the dealer is a phone call away, just have your VIN ready… Or maybe even take a drive down there…
Nevada also posted it for you…

Some of their responses are now written by A.I., and they might not be valid. I read recently that a teenager asked Google what he should do if he is being abused by his parents, and–supposedly–Google’s A.I. response suggested killing them.
We also had a new poster say that the responses given by experts here were wrong because his AI source didn’t agree with them. He wondered why he should return if we can’t give him a simple answer that agrees with his AI source. I did not post a response to him, but I wondered why he came here in the first place if he had an AI response that he trusted above all others.
