problem #4

525 6-cyl

  • 71,400 miles


Returning home from a trip to the grocery, car running fine, turned into my driveway, heard a noise, engine stopped running. Had the car pulled to my garage, , I am a diesel engine rebuilder so I do know engines. I looked the engine over with the hood up, didn't really notice anything. Got back in the car and tried to re start the engine, it rolled over fine but no start. I again looked in the engine area for any problems. Then I saw it. The front pulley and crankshaft was crooked, , very visible crooked. I reached down and grabbed the end of the crankshaft and it is broken. Never ever seen anything like this. The car only has like $71400 miles on it. This could have been a very serious condition if I had been on the highway. BMW has many problems with their engines. This is clearly a material flaw for a crankshaft to break. I have been reading lots of stories about their engines failing over bad materials used in building BMW engines. I think BMW should fix my car under a factory recall at no cost to me. This car has cost me tons of money to keep up, and I baby this thing. Engine failed going no more than 5mph in my driveway. And yes it was full of oil and all fluids. The car looks brand new. Thank you for any help on this. [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I was traveling approximately 40 mph on a city causeway. I went to apply the brakes for a red light and had none. The pedal was very stiff and had no hydraulic assist. I pushed the pedal as hard as I could and downshifted, finally stopping about 8 feet into the intersection. The car acted fine all morning up to that point. I had no warning light or anything to alert me to the failure. I have since found out that BMW issued a recall for this very issue on the V8 engine but not for the I6 engine which I have.

Clicking noise on car often. After researching there were more complaints of the same problem happening with other BMW's. was told by the BMW service center that the lifters need replacing. There are faulty lifters on the car could eventually ruin the engine head.

Reported engine leaking transmission fluids (less than 40,000 miles at the time reported) and was advised by BMW dealership that this is a common problem, repairs exceed $1000. BMW of North America, llc's advice that if transmission goes unrepaired, risk transmission locking up and no longer drivable. BMW is aware of latent defect and potential damage, should make repairs free of charge. BMW should also be concerned with environmental impact. Transmission fluid releases toxins that when leached into groundwater, realseases contaminates into soil and water, and potentially harmful to ecosystem.
