abs/brake lights come on intermittently and nothing wrong with brakes

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your Suburban. The ABS and brake lights turning on intermittently, despite no issues with braking, could be due to a few different things. The most common causes are a malfunction in the ABS, a faulty wheel speed sensor, or possibly even mismatched tire sizes. Sometimes, a problem with the ABS control module or wiring can cause the lights to flicker on and off. Even if the brakes seem fine, a diagnostic scan can help pinpoint any hidden issues with the ABS that might not be immediately obvious when driving. 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.
