BMW 135 owners have reported 1 problem related to radiator (under the engine and engine cooling category). The most recently reported issues are listed below.
I have a well maintained 2009 BMW 135i with 65000 miles. Yesterday, 1/21/15, while traveling at 75mph in 6th gear in the left lane of ga400, the car abruptly and without any warning overheated and lost all power. The car had been driving 100% normal, oil temps were normal, and had been in for a recent oil change and inspection two weeks prior with no significant findings. Fortunately, I was able to coast across cross 4 lanes of high speed traffic to make it to the shoulder. When I called two different BMW service centers from the side of the road, they said they could not see the car until February 3rd (two weeks) and were backed up on loaners and rentals as well. I called braxton automotive ((404) 367-4767), an experienced repair shop, and they, from my brief over-the-phone description, instantly identified the issue as a water pump failure, a very common problem in this n54 engine. When they received the car, they confirmed a catastrophic water pump failure and a consequently cracked radiator. I called BMW USA the night of the incident and learned that there is no recall or service bulletin in place. They were apologetic but refused to look into the issue unless I brought my car to a dealer service center. This was unreasonable because of the time lag and because I had already towed the car to braxton, who had had already identified and begun repair on the problem. I had swore off Bmws when I had my high pressure fuel pump replaced 3 times in the first year of owning this 2009 car. Now I am going to sell this dangerous piece of crap. Too bad, I love the way it looks and drives, when its not in the shop or shutting down at high speeds.
