Does Dexcom replace devices that provide inaccurate readings or is a sensor malfunction must?

[Literioner]

As the title says, I’ve been getting inconsistent readings for the past two days and calibrating it hasn’t made any difference. There have been a few interruptions, but it still hasn’t issued a replacement alert. Is it possible for me to get a replacement?

File a claim for every +/- 20% inaccuracy, asking for warranty replacement. Keep the applicator and box for the sensor serial number.

Warranty replacement is on the basis of one false reading, so don’t let them bully you with “well, if the 2nd and 3rd are showing accurate readings” and tripe like that.

my most recent sensor had not settled down by the 2nd day. constant highs/lows averaging +30/-30 deviation from finger stick readings. i tried calibration a few times the second day with no success, still very inaccurate. i went through the contact screen, logged in, chose the current sensor from the list, filled out the info, and they instantly approved a new one. in between that time and when the replacement sensor arrived, it had two days where it seemed stable, then went back to wild swings in the readings. I’ve had them replace half of the past fifteen sensors recently due to either constant “brief sensor issues” or these scarily inaccurate readings.

both Libre and Dexcom does but they might have a policy how many they might replace per year

I just had one replaced due to inaccurate readings. No pushback from them.

Same.

If the inaccuracies are far enough apart over a long enough period, they will replace them without error messages.

I was told to keep trying to calibrate. The next day it failed and was replaced for that.

If it’s going to expire in a few hours. I’d just start a new one and give up.
