I was driving on the interstate and my 2015 BMW 428i suddenly went into neutral and almost got us killed. Mileage at 88k, no check engine light, rattling, or leaking of fluids and car had just been to my local shop for an oil change the week before. Towed to BWW dealership, as car was inoperable, and told the engine had seized.

BMW N20 engine deteriorates itself by a faulty timing chain system setup. BMW has extended the limited warranty to 7 years 70K miles, but that is simply just not enough. My car, a 2015 428I, has symptoms of of the timing chain falling apart. Knocking sound, and very loud high pitch wine when driving. I have brought my car to the dealer and they say it's normal. When you look under the hood you can see the timing chain, it should not move at all. Mine moves up, down, left, and right, as well as the guide. BMW needs to make this a recall. My car is currently at 68,000 miles, and the warranty ends at 70,000. These engines are known for breaking after the 70K mile mark. This issue really needs to be a recall, and just have all N20, engines from 2012-2015's timing chains replaced, or extend the warranty to 10 years and 150,000 miles. As my car has all of the symptoms of a bad timing chain, I'm just waiting for the day my car breaks after 70K, and I'm stuck to deal with a 20K engine replacement bill. I know people with the BMW N20, engine who have had to deal with their broken cars due to the timing chain. This is just ridiculous, and BMW really just needs to recall this part. They like to call themselves the 'ultimate driving machine', but their cars can't even last past 70 thousand miles without having a complete engine replacement. This is ridiculous, and they need to make this issue a recall.

I smelled a funny smell, and then the entire dash went black. A "engine malfunction" warning came on. I stopped right away, got out of the car just as it burst into flames. The entire incident happened in a matter of seconds.
