This car seems to have a higher fail rate a lot of stuff than other cars do. I applaud them for trying so many things in different ways, but obviously the research wasn't there. It's like driving around a beta version of some final car that was never built... and this is coming from a person that owned and replaced/fixed numerous problems on a 15 yr old Town Car which was 20 years old when I sold it in 2009.
And a lot of other cars have an even higher fail rate.
Was at the car wash and this guy who just bought a 2011 Audi A4 is having some major issues with oil consumption. How the hell does a low mileage 2.0 4 cylinder burn a quart of oil between oil changes??
Heat makes things fail plain and simple. Good thing with the LS is once you fix it, you can expect it to last a long time and the issues it has are common and not very expensive to fix. As cars get newer they get more advanced and have more features which means more things to fail.
