The lacrosse leaks oil in the left front corner.

It may be caused by poor engine seal and excessive crankcase pressure. Because you can't see the real car, you can't accurately judge the fault. I suggest you contact the local 4S shop for inspection and maintenance. If the original parts are not used in the maintenance of the 4S shop, you can make a complaint on the car quality network.

In-cylinder direct injection technology is mainly used in luxury cars all over the world. To some extent, this new technology has become a technical barrier that luxury cars are proud of. BMW's top 760Li adopts V 12 aluminum alloy 6-liter in-cylinder direct injection engine, and Ferrari is also introducing V 10 and V 12 in-cylinder direct injection engines. And luxury commercial vehicles have also begun to move towards high efficiency. Audi A6 and LaCrosse, led by them, both adopted V6 in-cylinder direct injection engine, while LaCrosse was equipped with V6 in-cylinder direct injection engine, becoming a mid-to high-end car.
