Starting from a traffic light at woodlands parkway and gosling road in the woodlands, TX - vehicle accelerated normally during shifting from 1st to 2nd gear. When shifting from 2nd to 3rd - engine rpm went to zero and vehicle suddenly lost all power and died. There was a large Ford f150 behind the car. Thankfully, I was watching the tachometer and coasted to the shoulder before attempting to shift back to 2 and try a rolling start at which point vehicle came to an abrupt and sudden stop. Car was towed to an approved mechanic and was diagnosed as "another seized s65" engine. Opinion of expert engine builders and bearing manufacturers is that the original BMW s65 bearing dimensions result in inadequate journal clearance and has been thoroughly documented. This, coupled with any potential "tolerance stacking" (- clearance) can result in a final bearing clearance which is significantly tighter than ideal and is the reason why we have seen engines fail after only a few thousand miles. This was half a second or less from being a fatal accident.
Two weeks ago, when the car was driving normally, it suddenly shut down and could no longer start. When automotive engineers took the engine apart, they found that the crankshaft and rod bearing bush were over-worn and burnt out. The engineer told me that the oil I used was too sticky to lubricate the rod bearing. I changed the engine oil 8,000 miles ago, using the 10w-60 oil supplied by BMW.
While shifting into 3rd gear, my engine threw a rod through the block, car has not been modified, has 43,300 original miles, original owner.
O2 sensors constantly go out replaced 3 times, throttle body acutators constantly go bad putting car in limp mode very dangerous my car cut off at 65mph on the freeway. I was with my family!!! something bad could of happened. Please look into this BMW M3 2008-2013 please look into this. Rod bearings go bad aswell.
