Escalade IQ - Service High Voltage System

I have a brand new 2025 Lyric - same issue and the dealer says they cannot fix it. The car has completely stopped working leaving me stranded for hours each time. Sometimes the car goes into safe/low battery mode after the warning failure, even when it’s fully charged. When this happens, the vehicle will not accelerate beyond 60mph. In addition, when I got the warning, then next time I tried to charge, the vehicle wouldn’t accept a charge at all. I’m in a loaner vehicle - an Escalade IQ and it has 1500 miles and it it sending a “check transmission” warning. Once that happens the vehicle I will not shift into gear. So be prepared for that. 

Moreover, I’ve patiently tried to work with Cadillac EV Concierge - absolutely no help. They don’t return calls or emails in a timely manner. So I went to the Better Business Bureau for help, GM and cadillac are denying the car was in service - if not in service, why am I in a loaner? Then they said well, it only took 9 days to replace the HVAC (went out the day the car was delivered, 20 degrees outside). They lied and said I refused to pick up the vehicle, not true. I told them I’d take it, but under protest because I don’t feel safe in the vehicle, especially having been stranded in it, twice! luckily I have text message info from the General Manager and others where I began sending complaints day 1. I should have stayed with Lexus, but silly me, I was excited to have an EV with a greater range, little did I know Cadillac service centers are awful compared to Lexus and other luxury vehicle companies. My vehicle has been at the dealership over 72 total days!
