Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6) to whom it may concern: the 2008 BMW 335xi I have got engine over heated warming sigh pop out from car computer and the car lose the power right away while I was still driving on the fast lane on the free way which almost got me in accident front the car behind twice. I brought the car in to the dealer and they said there is error record showing my car engine been over heated but they cannot do anything about it that I need to contact Bmwna for solution. I did some research about my car does not come with the oil cooler which should original come install in the car since the car has sport package and Bmwna been doing retrofit to many other cars already. I mention that while Bmwna contact me but they said they cannot do anything about it even with the car did record engine over heated problem unless I over heated the car at the dealership then they will consider fixing the problem. Also since I am the second owner of the vehicle they are not going to od the oil cooler refrofit for me. I ask Bmwna they should take care this problem since the car is only 1 and half year old and the problem should be take car by warranty but they said they cannot do anything to fix it. This already have some serious safety issues since they know this car need to be putting oil cooler in order not to get it overheated and lose power while driving. Bmwna did the retrofit for first owner but I guess they do not consider the life of the second as important as the first owner too. Maybe they will state looking at the engine overheated problem like Toyota when serious problem start. Please look into this case for some second owner of BMW that Bmwna trying to ignore.
