Bought this vehicle from bank owned, it was 3 years old when bought, it had 70,000 miles. In one year of usage/service time, with 3 oil changes/2 with extreme oil burning. No signs of smoke, overheat, but within the 4th year of ownership it began to make engine noises. A rattling which as it turn out, and unbeknown to us vehicle was known to have problems with, and I took it to the dealer, they told us that the vehicle coverage was at 100,000 miles/a cut off for coverage on a class action suit. They took our car, stored it, because it had gone 120 miles over the cut off, and we're still waiting to see if they will honor their promise of coverage being that it's not an old vehicle.
