Medtronics didn't want to be outdone by St. Judes (Abbott) so they copied this feature. They'll just monitor more closely

from the website TCTMD 

Three cases of premature battery depletion in Medtronic PMs including one death/ Five  products lines  were identified;Azure,Astra, Percepta, Serena and Solara.(I don't t understand how six product lines were implicated in 3 cases). Problem said to be due to a cracked capacitor and the premature battery failure occured within 7 months of implantation. 

Medscape may 7 2019 describes "two dozen pacemaker models" under 5  products lines (those mentioned above)The alert cover 132000 PMS and CRT-P units. 

These cases involved a fully drained PM because of a capacitor crack and occured  "without warning to the patient or healthcare provider"

The FDA alert was issued May 7 2019.

They all use the faulty capacitors. Not good - mine is a Percepta Quad (W4TR01).

I was actually surprised to see that FDA/Medtronic published an alert on this.   The published failure rate at 0.0028% is quite low and the guidance to patients with the devices to seek immediate medical care if you get out of breath, dizzy, pass out is exactly the same for any pacemaker or ICD patient.  This is what I was told when I got my device in 2015, so I'm not sure the alert is that helpful.  The rule is "if you start feeling bad, get help quickly" with these systems.

The alert did say that Medtronic had deployed a new manufacturing step to help catch these cracked ceramic capacitors on newly made units.  If anyone out there has some details on that, I would certainly be interested in how they do that.

You bet! But it sounds like the failure is very quick.  I don't believe Medtronics have audible alarms, so it might not be noticed until the pacemaker was non-functional.  That would be good for those of us who are dependent. Paranoia strikes deep. Into your life it will creep.

I believe the Medtronic PMs do not have audible alarms but the ICDs may.

Again call Medtronic patient services and ask ( 1 800 551 544) they h ave been helpful when I have called and they answered their phone, better than the voice mail I get when I call my hospital based PM center.

I am not planning on letting any of this shorten my life. I am planning on living a long happy battery operated life. You never know maybe it will keep me alive longer. I sure know one thing I would have been dead before starting school without it.
