New gen dodge dart anyone having issues?

I have a 2015, with 2.0 and 6 speed manual, that has "blipped" on me 6 times in as many weeks. Blipped = dash flash, and slightest engine flutter. I wouldn't even call it a stutter. They just replaced the thermostat under warranty, but could not account or replicate the blip. It is on record, and I might have to get a dash cam to record if it becomes any more pronounced. The indepth scanners at dealer should be able to look at recent data, to see what is dropping (fuel, ignition, etc)
