What 2001 BMW 525i owners say
Engine & cooling
I had taken a longer road trip, and was on my way back, about a quarter of the way when we stopped for dinner. I parked, and everything was usual. A couple minutes later, I went to move the car, and while I was waiting in a drive-thru line, I see smoke billowing out from under the hood and I smell a burning smell. I parked the car back where it had been, and, thinking it was a coolant issue, opened the hood to let the engine cool down, and left my passengers with the car and walked across the street to buy some coolant. When I returned, my passengers told me that they had noticed a flame at the extreme front of the engine and had to douse it with water. I checked, and I saw that the wires leading to the auxiliary cooling fan in front of the radiator had melted and caught on fire and burned the plastic near them (as seen in the picture). …

Electrical system
We arrived at church, and I remained behind finishing my makeup. My husband locked the car with the fob out of habit, and my foot was holding the passenger door open. Forgetting the door had been locked with the fob, I accidentally allowed the passenger door to close. I had no keys. Services began, not a soul in site outside. I began to panic when I could not get the door or any other to open. The alarm would not trigger, and the sunroof was cracked accidentally about an inch. It was July. I could not get anyone to hear me, and could not get any door or window ajar. Eventually I was able to get the attention of an elder, who went and retrieved the keys and got me out. I was soaked in sweat, using an inhaler about every 20 minutes, extremely scary. The other time this happened, my son was sitting in the car but the alarm went off and would not let him out until I came with the fob. …

Air bags

BMW is using the recall to force people back into their service center. Even when a repair isn't required. Then, they tell you that there are 100 other things that are needed on your vehicle. Attached are the samples of the documents. This behavior is fraudulent and deceptive. Even though they know my vehicle does not need this airbag, they continue to send annoying letters.
