Broken cylinder head bolts at the front timing cover. Symptom was oil leak at timing cover. Upon inspection, the heads of 4 bolts had sheared off and 3 bolt heads had dropped through the timing chain housing and ended up in the oil pan. First, head bolts should not fail. Second, the sheared bolt heads pass through the timing chain housing and could interfere with the timing chain and cause immediate engine failure.

My car started having a massive oil leak at around 79,000 miles. The motor seals started to fail once the car had about 70,000 miles on it. The general consensus is that the motor seals are very common to prematurely fail. The bolts that hold the motor together started to break at around 80,000 miles.

I was driving my vehicle on the highway in the left lane, trying to pass a car in the middle lane. After getting in front of the car in the middle lane, I tried to accelerate so I could re-enter the middle lane, but the car acted as if it slipped into neutral and would not accelerate. The engine growled as if it were in neutral. It kept driving, but would not accelerate, despite me stepping harder on the gas. This was potentially dangerous as there was a car immediately behind me, which could have rear ended me at over 60mph, and the car in the middle lane that I was trying to pass could have also hit me on the passenger side of my car. In researching this, many BMW owners have been complaining about this, and yet BMW has not issued an investigation or recall: www.consumeraffairs.com/automotive/bmw_trans.html there are 650 complaints regarding this problem at the above link. People should not be having transmission problems like this under 75K miles.

Car only has 63,000 miles. The aluminum bolts for the valve cover and the head bolts sheared off while driving. Stopped at a red light and car starts to shake, check engine sign lights, oil sign lights, once I gave it gas. Oil is leaking from car. Car is towed and mechanic shows me damage. Broken aluminum bolts fell inside of engine. Bolt is wedged between timing chain and gear. The engine is destroyed. Known defect for 2006 models, but BMW North America will not cover damage. Have called BMW North America three times now. BMW switched bolt type in following years. Others reporting same problem. Safety hazard. What if I was on a busy highway when my car stopped? car will never be the same. BMW needs to admit to their mistake and cover the damages. A recall should be put in place for the bolts. Just ridiculous that a company known for quality will do this to their customers. I hope the dot takes it upon themselves to hold BMW accountable. Others with the same problem, please email me at [xxx]. looking for a potential resolution. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Independent repair shop noted aluminum head bolts broken which could cause extensive damage to engine. Broken bolts caused oil leak and heads of bolts could have gone into the timing belt destroying the engine. Independent repair shop directed us to the dealership stating they had noted this issues on almost all of this year and model. Repair cost was very expensive.
