New Ignition Coil at 31,000 miles?

I have a 2016 that was sputtering- I'm being told the spark plugs and ignition coil need to be replaced for $465. I thought they were supposed to last 100,000 miles. I'm also being told the coil is a maintenance item and not covered under warranty. Is that correct?

I did this at 50 Kms too! Me it was corrosion from our winter salty roads. I purchased a coil on AliExpress for $55USd ($75Cdn) ( https://www.aliexpress.com/item/3290...27424c4dgR06Ug ) and swapped it. The plugs were good and still are. Now at 51,000 miles ( 82,000 Kms )

Actually I purchased 2 in case this was going to be a problem, so I have a spare.

Here is a picture of what the contactors looked like and the bottom of the coil.




You can also get just the contactors if it's the only thing that went bad.

Hey Traxy does this sound like a common problem with all the trax years concerning the ignition coil and contactors? I have had an occasional sputter but it happens every once in awhile and i am at 88,000 miles.

Yes there was a bulletin out for earlier models, don't know if it's still in effect. The cure was to clean and add dielectric grease to the inside of the plug boot which I did when I changed my coil pack. I haven't pulled it out to check but everything is working well at this point. Maybe this would be a good preventative maintenance, just remember to lift straight up on the coil pack so you don't tear the spark plug boots.
