I charge my hot spot Wi-Fi in my 05 Tahoe that drains the battery at times although the vehicle does not start up once I’ve recharged the battery. It would start up then immediately shutoff. The shop has had replaced a sensor, BCM, and reprogrammed the vehicle anti theft which is becoming an expensive rabbit hole situation. I should also mention it starts backup after each repair although back to the same issue once the battery died. Any thoughts?

anti theft is reprogrammed but has the key or the key sensor been replaced? dealt with an envoy with that problem.
Thank you. It has not but it started after the reprogram so not sure if that would be it. It’s also a standard key not the electronic ones with lock/unlock feature. I’m not sure if you’re thinking that.

This doesn't sound right at all. Seems like the original problem was not fixed. The BCM is a major component, a computer and not a sensor.
Computer appears to be working right according to the shop but seems like they’re missing something

They ought to have performed a parasitic draw test and checked the entire system for trouble codes already.
