New cars often get started and stopped MANY times before even being sold. It is quite common for a new car to get one or two sets of plugs BEFORE the owner takes delivery. All those short starts/stops take a toll on the plugs.
When I worked for a VW dealer way back when... VW did not believe its dealers when they were replacing so many spark plugs on low mileage cars (~30 miles on average).
So... VW put these analog counters(up under the dash - to be rmoved durrng PDI or the first service) wired to the engine. Every time you started the engine it recorded the start. When the PDI tech took these counters off... many times they were in the 300 to 400 range of start/stops. That was when VW shut up and approved new spark plugs when we told them a car needed them.
And Btw... often times too... these low mileage cars also needed a battery... bc they were always being moved and never charged by driving the car!
So... OP it is quite possible your car need plugs. Its the first thing you should check. Also check the coil pack cables where they snap down. You could have a loose one. Go look at the Cobb video on my Replacing Spark Plug DIY.
Dack.
