BMW M3 knocking problems

Filed Apr 29, 2020 · Brakes, Engine · 73,800 miles · AE

While driving my vehicle, the engine suddenly shut off, and the transmission went into neutral. I immediately turned the car back on, and pulled to a stop sign. I gave my car a few revs just to make sure everything was fine. Everything seemed to check out, so I continue driving. While driving about 40mph and straight, the car shuts off again, and this time I have a complete loss of steering and brakes. Thankfully I manage to avoid hitting the car in front of me by using my emergency brake slowly. This time the vehicle did not turn back on. After researching this issue it's become apparent this vehicle is actually known to do this. Rod bearings and main bearings have caused these motors to seize while driving, and bmw refuses to acknowledge this issue. I could have killed someone from this issue, but it's sad all they care about is dollars and cents.

The crankhub on these cars are ticking time bombs and is likely to fail just outside of warranty forcing huge repair bills. In some cases, a "lucky" few just need to be retimed and only require 18 hours of labor. However, others have not been so lucky and have required an all-new engine. This is an issue bmw is fully aware of but has not taken responsbility for their insufficient engineering.

I was driving casually when the motor suddenly shut off. No noise indicating engine failure ever happened. I coasted off the road and tried to restart. Nothing but a click. Eventually tried replacing starter motor but that didn't work. No engine lights or codes ever popped up. Turns out engine seized due to failed rod bearings.

Approximately 5 miles after receiving the vehicle the rod bearings and crank suffered complete failure. I was in motion around 60mph on a rural highway when the engine suddenly lost power. After avoiding an accident I safely pulled over and shut the car off. The engine would not start. The seized engine was diagnosed based on an immobile crank and oil contamination by the manufacturer's dealership. I then had the oil pan completely removed at an independent shop to confirm the manufacturer's diagnosis, it was confirmed. All previous oil changes were done at the manufacturer's dealership by their technicians more often than the manufacturer recommends. The most alarming part is the vehicle has less than 23000 miles. I've reached out to the manufacturer, mentioning this very well-known issue and the fact that there are class- action lawsuits pending about this very issue, only for them to tell me they are not liable. Their product failed before 23000 miles, they know about the issue however they are doing nothing for me. The public should know about this failure because it can cause a sudden loss of power at any moment.

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.

Keep hearing a knocking sound on driver side when going over bumps. Feeling vibration under car under accelerating and breaking. Carbon fiber roof laminate peeling off.

While driving my low milage 2011 bmw m3 (42k miles) on the highway, out of no where, I noticed the car driving a little differently and slightly shaking. This happened moments before I reached my exit. I pulled over at a gas station right off the exit and opened the hood, the engine was making a tinging/scraping noise with each revolution. I closed it up, and drove to my home which was a couple minutes away. While driving, the noise was happening more in lower gears. When I got home, I looked under the car and saw it was leaking oil, and still making the noise. After some investigation, I learned the rod bearings in the engine had failed, resulting in complete engine failure. I purchased the car from an authorized bmw store at 38k miles in may of 2017, I always serviced it at my local bmw store - this occurred february 3rd, 2018. After reading up, I am learning that this is an issue with the s65 engines that are in this model of m3's. Bmw has yet to make a recall, but they are aware of the issue. No action has been taken, but something needs to be done. I can't afford a new engine (it costs 30 something thousand dollars, which is almost as much as I paid for the car), and the engine cannot be repaired. I feel wronged by bmw, and advise the federal safety agency to urge bmw to recall this engine to save future customers from catastrophic engine failure.

I've been driving bmw for over 12 years. My absolute favorite car to drive. I've had my m3 for a year. My dream car. I took the upmost care of her. Coming home from work late monday driving around 65-70 miles per hour. I heard a loud noise from my car and an engine malfunction notification on my car. Almost hit an 18 wheeler as my car lost control before I swerved into a ditch. Had it towed to my mechanic where he confirmed a piece of a rod poking out the lower part of my block. I never thought the rod bearing failure would ever happen to me! It happened. I currently have no car and I still make payments. I have to get a ride to work which I hate. Bmw should be held responsible for all s65 motors that have these no clearance rod bearings. This was my baby. Now she'll never be the same again.

Connecting rod bearing failure while driving. Starting making a loud ticking sound from the bottom end of the motor.
