Replacing ignition coil on Toyota Corolla on 2009 Toyota Corolla

Code came up as P0353 - ignition coil fail on #1 cylinder. Car is 2009 corolla, 39,254 miles. For those that have had this issue and have needed you know if this is typically a covered item on extended warranty? If not, what is the going rate for parts/labor. Can OEM parts be used or must they be Toyota parts only? Toyota is telling me this doesn't fall under their platinum extra care warranty nor the 7yr/100,000 certified pre-owned, but a few private mechanics are telling me they cannot believe this is not covered under either of these two warranties. Any input/advice is much appreciated.

Hello jacquel,
I am facing the exact issue as you posted. I am Wondering what did you find out after the appointment with Toyota. Is it covered? Do you had any loose gas cap to cause this? Please let me know.
READ the EMISSIONS warranty coverage.
its an electrical item and should not be under warranty. if coil is easy to get to try an aftermarket part and save a few bucks,if it hard to get to use orig factory part
Read your warranty! You paid for an extended warranty right? Bird dropping removal should be covered!
