I’m new to Prius and had our 05 Prius for 8 months with 170k miles. Vsc light and (!) came on before. Took to dealer. There was water getting In and they fixed it and then the lights came back on again after a week. What could be the problem. Dealership says everything is great on it obviously not but that’s what they say. Please help. Can’t afford thousands of dollars in repairs on our family car.
