Couple questions on this. First can you get a video of how you are going through this reset process?
You need to be in the vehicle with the door closed, key in the on position but the engine off.
Press the menu three times or until you get to the oil life screen. Then you need to hold the set/clear button until it goes to 100%. This may take a few seconds but if it does not go to 100% then it is not reset, and you need to hold the button until it does.
If you are holding the button for an extended period and it is not resetting, then we may have an issue with the button.
Please see the steps from the manual below. Just make sure they are the same that was in your owner's manual.
If none of this works, then let's get a video just to see if that will help identify the issue.
