Symptoms

The drill stops early or gives far less runtime than expected without unusual heat.
The motor can be heard, but the front output remains still in both directions with the bit removed.
The chuck still rotates, but a new mechanical grind, knock, scrape, tight spot, or severe vibration remains with the bit removed and is not ordinary motor or brake sound.
With the chuck stopped and battery removed, the top selector cannot be moved fully into range 1 or range 2, even after the chuck is turned by hand to align the gears.
With the battery removed, the clutch collar is physically stuck, cracked, excessively loose, or unable to align a numbered setting or drill mode with the index mark.
The battery stays physically latched, but the motor, LED, or both cut out and return when the tool or battery is moved through ordinary working orientation.
With the battery removed and the chuck empty, turning the sleeve rotates the spindle and motor freely instead of providing enough lock to tighten or loosen the chuck by hand.
The trigger returns normally and power drops, but the anvil repeatedly coasts instead of stopping promptly.
The motor can be heard running, but the chuck remains still, pauses independently, or free-spins without transmitting normal drive in either fully selected speed range.
THE BATTERY WILL NOT SEAT, LATCH, RELEASE, OR STAY SECURE
The chuck jaws open and close normally, but a straight compatible bit rotates or pulls out during moderate drilling or driving.
The direction selector is centered, but the trigger still depresses enough to start the motor or the center position cannot reliably prevent activation.
A compatible V20 battery starts onto the tool rails but binds before reaching the normal seated and latched position.
THE DRILL/DRIVER WILL NOT START WITH A VERIFIED BATTERY
The collar moves and holds a low numbered setting, but the clutch does not ratchet before a test fastener is overdriven in suitable scrap material.
With no fastener load, the bare or correctly fitted output sounds harsh, binds, knocks, or shakes abnormally.
The direction lever will not reach forward, reverse, or center lock, or the selected position does not hold.
The direction selector moves and holds normal detents, but the chuck fails to run in one direction or rotates opposite the selected arrow.
A sound V20 battery is fully seated, the direction button is fully forward or reverse, and the tool gives no motor sound, LED response, or chuck motion. The dead state persists when the tool is held still.
The drill sounds and rotates normally with no load, does not stall, overheat, slip, or vibrate abnormally, yet a corrected drilling or fastening task progresses much more slowly than expected.
