I don’t know if I’m just unlucky. Or are BMW cars poorly made? I’ve had one consistent problem ever since I have owned the car. My key is a remote access fob. Just by having it in your pocket, when you place your hand on the door handle, the car will automatically unlock. You can lock the car by touching the top of the handle. And you can start the car by pushing the On button. But the locking/unlocking part is unreliable. Sometimes I have to try multiple times. Other times, I just give up and use the button on the fob. Of course, the dealership never does anything about the problem. I doubt they seriously try to see what the problem is.
But I have had other problems. I have had the check engine light come on, had rough idling, erratic idling, and no power during acceleration at various times. Each time I brought it in and it was fixed.
On July 6th, 2010, BWM replaced all of the injectors, the coil, and the spark plug of an affected cylinder (unknown which one it was).
On September 23rd, 2010, BMW replaced the intake solenoid.
On December 20th, 2010, BMW exchanged the HDP. Which I think was the N54 high-pressure fuel pump because of the warranty recall number 10E-A02.
On January 14th, 2011, BMW replaced 3 piezo injectors. They also removed my aftermarket car computer software (which is fully warrantied and sold by BMW by the way). Apparently, there was a software bug that dealt with the torque sensing.
And on February 15th, 2011, they reinstalled the Dynan car computer software with an upgraded release.
The positive thing about these problems is that I get a new loaner car. And I have tried different models of BMWs. I really liked to drive the Z4.
This may not bode well for the future. I doubt I will keep this car when the five year warranty is up. I am guessing that this is an expensive car to fix.
