First I got the tighten fuel cap message, I tightened fuel cap and after driving a few miles the notification disappeared. I noticed my “Miles range” would jump from 350 to 309 after only driving 2 miles or so, I expected it to go back to normal after driving my car again but it didn’t. when I left for work the next day, I got the “check emissions system“ message. then when leaving work I noticed my miles jumped back from 298 to 309 and then when arriving home it said I had about 250 miles until empty. My drive to work is only 23 miles. The gas gauge however was not jumping, just the miles until empty message on my dash. I’m taking the car to the dealership tomorrow and they’re going to put a scanner into it and check what the problem is but I figured I’d ask on here first to maybe help alleviate some stress
