I was turning on to a highway, as I accelerated to match the speed of oncoming traffic and merge, the engine power abruptly degraded. I had to swerve out of the lane to avoid an accident. The vehicle had a flashing service engine light and was not producing any power. I had the vehicle towed to park ave. Bmw in nj. The dealer diagnosed my vehicle with a failed dme (engine management computer or ecu) at less than 60k. After doing some research I found many others bmw n54 engine owners online who had encountered the same dme failure. It turns out an electrical component that costs a couple of cents was prematurely failing. This was known to bmw in 2007 when the vehicle was being sold. The bmw service builtin si b 12 18 07 clearly indicates that this is an unexpected failure and is caused by a defective diode. Further more the issue can damage coils and fuel injectors costing thousands of dollars. Replacing coils, injectors, and the dme can exceed $5000. Further more bmw chose no to be proactive and replace the component, instead they put peoples lives at risk, at best their benefiting from their own lack of quality.

There is a serious defect with the engine and fuel pump. It takes a long time to accelerate when driving especially on the highway, the car will shake, jolt and the engine will start to make a weird noise. There is oil leaking constantly and the check engine light is constantly coming on even after just being repaired. The car goes into limp mode and has shut down on me numerous times while driving. I've had the fuel pump replaced numerous times and yet it needs to be replaced against. The car will overheat at times and and just shut down. I was driving on a busy city street when the car just shut down, I couldn't steer or brake it just died in the middle of a busy street. It was extremely unsafe and put my life in danger as well as the other drivers on the road, especially since they were driving at fast speeds.

While driving on the hov lane of the freeway during rush hour about 5:15 pm my car suddenly started to rattle when pushing the gas peddle. I took my foot from the gas peddle while still driving with about 60 MPH. I tried the gas peddle some seconds later again and experienced still rattling and no acceleration of the car. I took my foot again from the gas peddle. In the meantime I was down to 40mph. About 20-30 sec later from the first rattle the engine light came on and 1 sec later the engine stalled on the highway. At that time when the engine stalled I was still driving about 35 MPH. Luckily the freeway had a left shoulder and I turned over to the left with the last remaining speed and slowly stopped the car. I'm so glad that the left shoulder was available. The freeway was very busy and I assume I would have been involved in an accident, if the left shoulder wouldn't have been available. The loss of power was too sudden and entirely unexpected. The stalled engine created a very dangerous moment while driving on a freeway. The bmw shop came back to me today and explained that the high pressure fuel pump failed. A know issue with the car make, model and year.

My car might have turbo charger issue that was settle under class action in 2010 . I'm being charged for repairs that will able bmw to make diagnosis for that problem at first for vacuum turbo lines almost for 1000 dollars and today for some other issue another 500. I'm being pressured by bmw to fix it or quit. The extended warranty is only till 82 thousand miles. So either I pay or end up not knowing if my car has this issue. When I was driving and trying to speed to pass another vehicle my engine light came on saying that engine is not working in full capacity and to slow down or stop... Pls help me to resolve that issue. Thank you. I called bmw or northern america and spoke with sky and was told that it is what it is and I have to pay since the mechanics know better what needs to be done. When I asked for somebody that is in direct relations with bmw of germany I was told that he is the top of the line person and entity in his self. I feel that anything related to this issue should be cover by bmw not me.

The thermostat was failing to cool the vehicle under extreme heat conditions (over 100 degree days), took vehicle in to check the thermostat, but it was only a 90 degree day when they looked at the car, and were "unable to reproduce problem", so they returned the vehicle. About 6 months later, I took vehicle in to check the thermostat when the vehicle was unable to warm up under extreme cold conditions (under 30 degree mornings). Again, "unable to reproduce problem" because when the mechanics got to work in the morning, the temperatures were over 40 degrees. Other than extreme conditions, the thermostat seemed to work fine. But the following year, on a cold morning, not only did the vehicle fail to warm up, but the "check engine" light came on. By the time I was able to make an appointment and bring the car in, the light had gone out, and again, the service dept. Was unable to determine what made the "check engine" light come on. They said it must be an "intermittent problem". Yes, it was!! And the light came on another time, but I was out of town, so that by the time I got back, again it had gone out. The problem finally got bad enough for the light to come on again, and this time I drove the vehicle directly to the dealership w/o turning it off, so they could determine the problem. They finally confirmed there was indeed a problem with the thermostat, like I had told them all along, and they replaced the thermostat. When I got home and checked the internet, I found many complaints about this same problem with my engine in this model bmw. And bmw has not made a recall to repair the item. This is a known and frequently recurring problem that bmw should be made to pay for &/or reimburse customers for expenses they incurred in fixing the problem, just like the fuel pump and battery problems for this same model vehicle that were fixed under recalls!!
