22 Defender shuts off/stalls when idle due to faulty auto-stop/start

That's part of the battery monitoring system. Unplugging prevents battery data from being sent to the ECM which then will not engage start/stop as a fail-safe. Other systems are also involved.
Aside for the unknown (safety?) systems it would impact, it would seem like a bad idea simply because it's a glass matt battery and that may have something to do with charging. AGM's are temperamental.
@The Insider any info on this? We're clearly just wild-*** guessing.

Happened to me twice today. Seems like the “starter-motor-generator “ cant turn over the engine. The motor defaults to the other “primary?” starter when i restart.
LOL My service dept told me to sit down with their “technology specialist” when i described this issue. Maybe i shouldn’t but i find that kind of insulting

Said it before on the forum and I'll say it again. I only ever saw stuff like this when my Defender was new and/or had not been driven for a while and thus likely to have a depleted battery charge. Since then I've been topping up the battery from time to time if I'm not driving enough, and I've had no issues.

Yes, I do remember you mentioning this and agree it could be related. I monitor battery voltage via a dongle & when my Defender did not restart and put itself in park, in the middle of a busy intersection, voltage was 14.1.
One point on my Defender: It only started doing this after it was at the dealership for 2 weeks for repairs. I would bet the battery was indeed depleted with the updating/service they were doing. I could.
This is an extremely problematic safety issue and someone's going to have an actual accident.... Last incident with mine was pulling out of a Starbucks. I was in a turn lane / lane of traffic in the middle of the road in Lake Oswego OR ... Fedex truck barreling down on me from behind, changed lanes to avoid slowing down. I was worried someone might be following that truck closely.
