Catastrophic engine failure... not exactly what you want to hear no matter what you're driving, but especially so when you've just purchased a brand-new 2013 BMW M5 or M6.

According to the National Highway Traffic Safety Administration, "a manufacturing process error" could cause the oil pump's driveshaft to separate from its rotor, leading "to a sudden loss of oil pressure causing the possibility of complete engine failure, resulting in an engine stall-like condition, increasing the risk of a vehicle crash."

As is always the case with such recalls, BMW will be contacting owners and dealerships with plans to fix the problem free of charge. On the plus side, we'd imagine some owners already know of the problem, considering the brand issued a stop sale notice on the M5 and M6 on September 21.

In kinda-sorta related news (hey, Mini is owned by BMW after all), a recall notice has also been issued for certain 2011 Mini Clubman and Clubman S models regarding a glitch that may cause owners to miss an in-dash warning for malfunctioning ABS brakes. Not exactly catastrophic engine failure, and it only affects 75 cars, says NHTSA, but you can find both recalls in their entirety below.

 

I wonder how they discovered this one, and better this early than after a few casualties down the road.

lol that was fast

 

that was on people on a forum having oil pump issues. This is a real deal recall that BMW has recognized.

 

I wonder why this is happening in the M5 and M6, but not the X5 M or X6 M, which essentially use the same engine.

 

werent some of the AMG motors having issues??

 

That is true, but within that post was this link posted by STIG:

Same issue, not a big deal either way.

This is an interesting development. It appears that the oil pump's drive shaft is in threat or has been separating from the rotor! The loss of pressure causes a massive engine failure. Do you think they adequately track tested the new engines?

It has to be a serious issue to issue a stop sales notice...and they did.

Go with the F.

 

it is never the same engine, thats why :-).

 

IMHO, that would be possible IF AND ONLY IF:
-Lexus releases a GS-F (for real)
-and that it must have at least 500 hp.

Remember, that the BMW M5 and M6 are not the only cars in this segment. You still have:
-E63 AMG wagon (Mercedes Benz)
-Audi RS6 wagon next-gen (in a few years time I believe)
-Jaguar XFR

So, Lexus needs to achieve those two things first before those buyers start looking at what Lexus has to offer in this segment.

 

Actually both are the same engine (S63B44).

Which is strange because they're both the exact same engine..........with the only differences being that the 'technical update (TU)' version that is used in the M5 and M6 has:
-higher compression ratio
-higher boost pressure
