Default 2018 Cx5 GT lack of power very weird issue!

Today when I went onto the highway to go uptown about a 15 min drive. I went to floor it to pass someone and the car bearly accelerated it felt like it was down about 100 hp it just seemed to rev up so slow also no check engine lite on either. When I got to a stop sign I floored it again to see and it went so slow and when it shifted it jerked ahead pretty hard. Just seemed to labour bad. Went to my appointment and same thing on the way home.
When I went out about half hour later to go shopping it was perfect again thing pushed me back into the seat like normal. Anyone had this problem or if there is any tsbs? I’ll tell the dealer when I go in next week also to get my new motor mount replaced from freezing up and see if they find anything.
Thanks

Did this happen right after filling with gas? There have been a lot of reports on the MX5 that overfilling can cause this type of reaction. It usually clears itself after a couple of shutoffs and restarts.

Ya it felt like it was running at half power. Didn’t use the park break either.
