Business ProfileforMercedes Benz of Melbourne

We purchased a used 2018 C400 in October of 2020. The car comes with a four year 50k factory warranty. The finance person sold us a two year EXTENDED warranty, which I knowingly and happily purchased because I know the price to repair a Mercedes. A week ago, the car developed an oil leak. I took it to the dealership to have it repaired under my extended warranty. I was informed that my warranty had expired. Which was odd, because the two year extended warranty was purchased in October of 2020 and the factory warranty ran out in 2022. I was informed by the service technician, Adam, that the extended warranty start date was not AFTER the factory warranty ran out. It started the day we bought the extended warranty. So, the dealership knowingly sold me an extended warranty that was effective during the FACTORY WARRANTY. Who in their right mind would pay 3k for an extended warranty if they knew it would actually not "extend" the factory warranty but start and run concurrent to the factory warranty? Essentially, the two year extended warranty was good for about one year after the factory warranty ran out. I specifically asked the service person if he understood the dates the same way that I did and he in fact agreed. That the so called "extended" warranty actually was effective during the factory warranty. He said the sales manager and service manager both said there was nothing they could do about it.
