Maintenance at 1521 Miles Plus Some Other Questions

[TurboWarp]

Hi All,

Still loving and learning my 2026 CT5 V BW. I was considering an oil change as a safety measure. I dont see a concensus on this. Thoughts about any maintenance for this new car?

Other Questions:

-On the headlights stalk at the end of it there is a round spring loaded button that pushes into the stalk. Dont see this in the manual. Anyone know what this does?
-If I put the exhaust note in stealth mode does it impact performance?
- At idle after full warm up, engine runs a little rough most of the time; is this normal?

Thanks....

I don't care what anybody says. I have ALWAYS done a break in oil change on my new cars at about 1000-1500 miles. I used my free 1st oil change to do it. Its cheap insurance. Every engine builder that I have ever known does it too.
My 2022 5BW/auto has only 6800 miles on her in just over 3 years of ownership and its had 4 oil changes.

The button is the auto high beams.

FLYARMY and rubberduck. Thanks for the replies. I think I will do the oil and filter change. I the "good old days" I changed my oil every 3K to 5K.​

My 2024 has run slightly rough at idle from new also(hot or cold)… anyone else?

I have 1,875 miles and first oil change was at 917 miles.

Not only did I change my oil at 1k, I also changed the rear-diff fluid at 1.5k (right after diff break-in).

If you like your car a lot, then I would definitely be a step ahead on taking care of all the maintenance while being proactive - just like you are right now.
