Since we got the van it was a new vehicle and the engine light has consistently come on. the dealer tryed to tell us we were not tightening the gas cap. then it was we needed a new gas cap. you have to take it to the shop every time the light comes on. one mechanic stated it was an 02 sensor that was supposed to have been replaced after much hassle. now 10 days later the engine light is back on. the warranty is about to run out. *ak
