Escalade IQ - Service High Voltage System
Our new IQ is already in the shop after less than 300 miles with a Service High Voltage System message. After being in the shop for a week, we were told that it was related to a water pump/ radiator failure. Now we are being told that after replacing the part that vehicle now has communications issues with the battery. We have been told that the local service center has contacted GM on information how to repair it. There are other less serious issues but real problems also. The hood and truck randomly opens when you walk by it sometimes. We also get a interior alarm notification every night. I requested a new vehicle but ofcourse they said that is not an available option without GM approval. It's unfortunate that we traded our paid off family SUV on this IQ and now are stuck in limbo.

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!
