2022 Cadillac Escalade — battery dies after the car sits for a weekend

BoxerHauler225Community StarterFeb 9, 20262022 Cadillac Escalade SportCleveland
2022 Cadillac Escalade Sport, about 65,500 miles. Battery passes a quick test and charging voltage looks normal, but after two or three days parked the car sometimes will not crank. What is the cleanest parasitic-draw test on a modern car that takes time to go to sleep?

Intermittent stuff lies if you only catch it once. If a shop can't duplicate it on the 2022 Cadillac Escalade, bring a video plus freeze-frame data, not just a story. Save the big job until that test fails. On “battery dies after the car sits for,” that was the fork that mattered for me. This is from a 2022 Cadillac Escalade in Cleveland with 65,500 miles. Keep sale price, fees, and rate as three different conversations. Video is ugly but it shows the hesitation.

I wouldn't throw parts yet. Swap the cheap/easy piece first on the 2022 Cadillac Escalade and see if the fault moves. Save the big job until that test fails. Learned this the expensive way on a previous car. I'll poke at it this weekend.

I'd want a measurement, not a hunch. Loaded-suspension checks on the 2022 Cadillac Escalade catch play that a wheels-hanging inspection misses. You'll know quickly if you're on the wrong tree. This is from a 2022 Cadillac Escalade in Cleveland with 65,500 miles. Verbal 'we'll take care of it' is not a plan. I'd rather be boring and correct. Doing the boring step first on purpose.

I went back under the 2022 Cadillac Escalade and it only happens after a heat soak, not on a cold start. Parking it somewhere I can hear it better next time.

Start with the test that can prove you wrong. Write temp, speed, and in-gear vs coast when the 2022 Cadillac Escalade does it — then decide on parts. That's the branch I'd chase this week. This is from a 2022 Cadillac Escalade in Cleveland with 65,500 miles. I'd want a dollar figure or a measured spec, not 'should be fine.' Cold start is when I can actually reproduce it.
