Took vehicle in for oil change around 30k miles, tech called me back to show me oil leak. Further investigation found oil leaking from head gasket and crank shaft caps. Everything replaced under warranty. 10k-15k miles later same issue happens again. Everything fixed under warranty again. Few thousand miles later my wife backs out of driveway and there is a puddle of oil under the car again. I got rid of the car before failure again and warranty is expired. Car always handled well, great gas mileage. Terrible acceleration and quirky transmission.
Took car in to dealership for oil change, tire rotation, etc. And was told it had an oil leak and that they wouldn't fix it (it's still under warranty) until the leak became worse!.
