Worst dealership ever visited. Told me that they gonna charge me 100 bucks for each problem diagnosis. Are you really serious. How i would know whats wrong with my car engine and stuff. Its ridiculous. Wasted my 100 bucks and then they told me that the sensor is bad. Really!!. But what's wrong with the engine then. Emmmm. Get ready for another 100 bucks to know. Ridiculous.
