Usually one is a service vehicle soon and the other service engine soon. They are different. The service vehicle soon is telling you the body has an electrical issue and the service engine is telling you you have a powertrain issue. If you get the codes pulled from the engine at auto zone or another big box part store for free and post the codes we can help. This we do first. Then we can worry about the service vehicle soon.
