| Jan 2018115000 mi | car had oil consumption problem when we purchased it, previous owner did not disclose and it was 2k miles out of warranty. Audi would not extend or honor warranty outside of 80k. Seperate issue- car lost power going up hill. Mechanic said it was the timing chain (supposed to be lifetime). He said they are repairing at least one timing chain a week because they "stretch out" and then fail. When they fail you have to replace the entire engine. Parts and labor quoted by several shops 10k-12k depending on if purchase a used or new engine. We are going to walk away from the car. It was a pleasure to drive, beautiful, and we absolutely loved it. But we have a hard time with a company and/or product that has major defects and consumers are not told about it or have to pay for major design flaws. The car was a ticking time bomb. | ||
