Good news first: an original motor strap on a high-mileage 2019 Comp isn't a warning sign — it's a sign the drive unit's been left alone and hasn't needed pulling. On the 2019 Levo Comp you've got the Brose-based Specialized 2.1 (90Nm, ~560W peak, 410% assist, belt drive). The belt is the thing to keep an eye on as the miles climb, not the strap.

What actually wears on a 2.1 at high mileage
The drive belt — the internal Gates-style belt is the known consumable on the 2.1/2.2 units. Belt slap, a rattly graunch on load, or inconsistent power delivery usually points here.
Sprag clutch / bearings — 2.2 brought bearing and sprag upgrades over the 2.1 exactly because the earlier unit could get notchy or noisy with age. If yours is still smooth and quiet, brilliant — that's a well-treated motor.
Overrun feel — a bit of surge or lag after you stop pedalling is a common 2.x trait; @DylanJM noted inconsistent overrun on the later 2.2, so a touch of it isn't automatically a failure.

The one genuine Achilles' heel on your Gen 2
The battery-to-motor cable connection. @Just gan flagged that Gen 2 Levos could throw a fault a day or two after a hose wash, needing the crank pulled to dry the cable out. So go easy with the pressure washer near the motor — that catches out more high-mileage Gen 2 owners than actual motor death does.

If it does eventually let go
A full-power upgrade path exists: the 2.2 is backwards-compatible with the 2.1 mounting, so a swap is feasible rather than a whole-bike write-off. @Bearing Man's outfit and other eBike Motor Centre partners can recalibrate the torque sensor on Brose units too, which is worth doing if the power delivery ever starts feeling off before you assume the worst.

Practical take: keep riding it. Watch the belt, keep the wash gentle around the motor cable, and don't touch the strap unless you're actually pulling the unit. A 2.1 that's this far into its life on original internals is doing exactly what you'd hope.

How many miles/hours is it actually on, and are you noticing any specific noise or power drop-off — or just doing due diligence?
