The VSC warning light and the check engine light on my used Camry 2009 XLE turned on just after I drove it for few miles after purchasing it from the dealer. I took it back to the service and after checking it, they said that the sensors needed to be calibrated and promised to replace them soon since it is still under warranty. They informed me that the VSC warning sign and light will not turn on, but the check engine will be on until the sensors are replaced. However, the VSC warning and light kept going on and off again. My question, is it safe to drive the car as is at this moment?
