[Scarlet 258 FTNT]

I assume the RS would have the top trim, in all areas, but, having bought it new in '21, I have, not once, seen a rear seatbelt alarm...the majority of the time (95%+) the belts are unbuckled. (Rare that I have back seat passengers.) Same with '18 SS.

That being said...

When the inside of the car is cleaned (in for Zactec treatment or just 'regular', when allowed by me, after service), I have noticed that all back seatbelts are buckled....same with '18 SS. 100% of the time. I just figured it was to 'look tidy.'

So with one, some, or all, but never mine - buckled or unbuckled, but not occupied - I think we may have landed on, yet another, Infinity manufacturing inconsistency.
