Light comes on saying service hybrid system

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. So sorry to hear you're having trouble with your vehicle. When your Tahoe shows a "Service Hybrid System" light, it alerts you to an issue within the hybrid components. This issue could involve the battery, inverter, or other related systems. A failing component in another vehicle system that interacts with the hybrid components could also be present. Ignoring it could lead to more serious problems, and with hybrid systems, it's always best to be cautious. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
