Default BMW X5 50i - N63 - Engine Failure - Any Advice? - 07-03-2020, 09:05 AM

I've got a 2012 BMW X5 50i with only 70,000 miles that just, out of the blue, got an error that said it was running at 50% power and to get serviced as soon as possible. Before I could get it home (less than 3 miles), it started knocking. Got it into service and the engine is blown. Apparently it's a common issue with this engine (4.4l v8 twin turbo) called hydro-lock, where at least one cylinder floods with liquid gas and eventually causes a rod to break. At any rate, local BMW service center said they thought BMW North America may help out with a replacement engine (nearly $40,000 to replace). So, I contacted them and, unfortunately, after 4-5 days, they say they're not going to offer any assistance at all. But, if I want, they'll give me $1,500 for the car as a trade-in on a new BMW. LOL. That $1,500 offer was insulting, to say the least. At any rate, does anyone know if there's any further recourse / action I may be able to take? This is a known problem with these engines and there have been several class action law suits filed against BMW, but they have all settled out of court. The local BMW dealer said they had hoped it was the timing chain that broke, as they would likely replace the engine if that were the case. But, since it was the hydro-lock issue, they're not going to help. Any advice from anyone would be greatly appreciated.192.168.0.1 routerlogin 192.168.l.l

Doesn't surprise me in the least that they won't pay anything. Its an 8 year old truck. They have no reason to. They pulled the same thing with me when my 750 started leaking, and that was barely out of warranty. The $1500 offer is actually pretty fair. The truck likely books for the mid $20's in good shape, and its gonna cost that to replace the motor, so paying more would be foolish. All I can suggest is getting a motor from a junk yard and putting that in, and then sell it before the "new" motor goes. The original N63s issues are well documented, so keeping a vehicle with it is always going to be a money pit.

Check the history of the car, when my engine blew after only 2-3 months of owning it, I found out that the previous owner didn’t respect the oil maintenance schedule. Long story short, BMW Canada paid for the engine, the installation, miscellaneous parts and whatnot... And I got brand new 530’s (every 5k miles) for the 6 months it took them to do the work since the motor was back order

Ive never heard of hydrolocking as an N63 "issue".

The only notable issues on the N63 is Valve Seals causing oil consumption, stretched timing chains, and in some instances crankshaft bearing failure.

There is a Class Action Suit 'Bang vs. BMW' that now allows any owner of any N63 non TU BMW to get the valve seals replaced up to 10 years or 120,000 miles. The Dealer will perform an oil consumption test and will replace the valve seals at no cost.

In some instances the dealer and BMW may determine that engine replacement is necessary, and this will be at no cost up to around 75K miles ,then prorated after that up to 120K.

Also to note, you can get a BMW Remanufactured N63 Long Block Engine (they call it a short block but it has heads fully installed and assembled) for $3,200.00.

Plus a $3000 core charge. Still dirt cheap. The N63TU is over $30k
