Timing chain in engine failed while the vehicle was going 70 MPH on a busy highway. Vehicle had 96,054 miles. -??Low oil pressure-?? warning came on and immediately the engine lost compression and car had to be pulled over to side of the highway. The spot the car stalled was in a dangerous curve of the highway making the towing process dangerous. Vehicle does not switch into neutral when the engine isn-??t on. Vehicle had to be dragged onto tow truck ruining the tires. Quoted the repairs at 6 different shops and they were all very familiar with this issue. All estimates for engine repair exceeded the value of the vehicle. Additional costs may have also been incurred as oil pump may have been damaged from timing chain failure. BMW never notified me of the timing chain issues and no dealership I had prior work at ever mentioned the issue.

BMW failed to inform customers about the class action lawsuit several years ago due to the premature failure of the primary and secondary timing chain assemblies for N20 & N26 engines. See SI B11 03 17. Owners of these vehicles were never notified of this documented and extremely hazardous problem. The government should make this a recall and not allowed it to just be an extended warranty that has since expired and was unknown to many owners. There are thousands of these vehicles on the road with this defective part that could suddenly cause the engine to cease working, resulting in an accident that could cause injury and death to many. If this chain fails while driving it is catastrophic to both the car and the people. A recall should be issued immediately.

The engine component caught fire spontaneously when car was pulled into a parking lot. There was no warning sign. It did not show any service required notice like it usually does on the dashboard for example if oil is low. There were no recalls pending on this vehicle. The fire was big enough that we had to call fire department to put out. It would have affected other vehicles if not put out. The vehicle was declared total loss after an inspection by insurance company. The car manufacturer (BMW) was contacted but not responded yet. It is available for detailed inquiry and inspection in a secure place.

Timing chain system failed. Inspection no longer possible due to being repaired in order to be used and not blow engine. Daughter driving on freeway to Phoenix, AZ in 115+ degree weather and left to sit on side of rode with no A/C until tow truck able to tow vehicle rest of way to Phoenix, AZ. Chandler BMW confirmed issue and repaired. Independent service provider in hometown informed me of every BMW owner having this issue a few months after repair. Discovered class action lawsuit from several years ago after research regarding this exact issue. Unknown of symptoms prior to failure, but vehicle has been very well maintained since purchase just about a year ago (2 trips to independent service provider in hometown and one trip to Chandler BMW mentioned above). Approximately 105,000 miles on vehicle at time of timing chain issue.

Timing chain tensioner failed clogging the oil pump with plastic which in turn starved the engine for oil. We got a low oil pressure light in the Interstate at 70MPH. 10 seconds later trying to pull across 3 lanes of traffic the engine seized. Luckily we were able to coast across the 3rd lane onto the side of the Interstate. With traffic flying by I had to get my family into an uber. I realize the class action suit ended but my car barely has 70k miles on it. I don't see how bmw could get away with this. There are many of their cars that are past the 10 year class action suit but under or at the 70k mile cut off like mine. The car is still at the dealership. It has been inspected and I have been informed that I'm not eligible for the repairs to be covered. The dealer wants 15 thousand dollars for a new engine to be installed on a 12 thousand dollar car. They have offered to sell me a USED engine with 135000 miles on it for 12,000 installed. Imagine the story this would be if one of my family members or myself had been hit on the Interstate trying to get into another vehicle.

Timing chain guides broke while driving, so timing chain jumped a tooth and now car will not start because incorrect timing Car has only 92,000 miles

I checked the car history report for this car, it said that it had all of the scheduled maintenance. I have not driven this car hard, I used the best gas I could. I had this car for only 4 months - I took it in to Carmax to get checked out about 2 weeks after I got it back in October. They ran tests, and told me everything was fine that "it could've been a loose fuel cap". 3 months later, well before even an oil change was required - my car gave me the same error message only now it would turn off everytime I put it in drive. If this happened on the road I definitely could've been killed. This car showed 0 signs of any type of malfunction and did not give me any indication that anything was wrong. Fast forward to taking it to the Mins Auto (BMW recommended) they informed me that this car did not in fact seem it had regular oil changes contrasting what was in the carafe report. the timing chain seems to be the culprit and now I'm stuck with a $10,000 bill on a car before it's first oil change, on top of the dealership (carmax) not being helpful at all - when I did everything right with this car. When MinsAuto ran tests they found so many errors - I don't understand, neither can they - understand how Carmax could miss any of these. I was also told by them that because this happens EXTREMELY frequently on these 3-series models, they are pretty familiar with the process and it takes exactly 24 hours to remove the engine, the pistons and take these things apart. so I think this should be investigated and taken seriously. Thank you

The timing chain went out. Warranty was extended to 70,000 miles or 7 years, but this is outside the range of many of the incidences, including mine. I'm getting multiple misfires and you can hear the timing belt when the engine starts, if it starts.

I recently had my car serviced and the oil changed over the summer, so there were no warning indicators or service issues prior to this incident. I left for work and had no indications of any problems. I drove for about 10-15 minutes when a warning notification popped up stating engine oil pressure low. A few seconds later, the check engine light came on with a notification there was a "drivetrain malfunction". The car started to decrease speed significantly and I pulled over as soon as I could. I turned the car off and waited a couple minutes, then tried to turn it on. The car power/battery was still working properly, but the engine did not start. I had the car towed to the dealership that I use. I was notified that the drivetrain malfunction is due to "timing chain components failure" and the cost is approximately $16,000. I have taken care of any previous recalls and there are no open recalls that exist currently. In 2014, the same situation occurred, in the same car, where I also received a "drivetrain malfunction" and check engine light. During this time my vehicle also stopped working while I was driving it. Both of these incidents happened very quickly, and I am EXTREMELY lucky that no one was injured in either situation. This issue is extremely unsafe and clearly has not been fixed by the required recalls so far. I urge you to look into this further.
