I am really bummed out. I own a low mileage 2011 335is coupe, which I loved - until now. Several months ago the car abruptly stopped on the road and displayed the yellow, then red thermometer. I had to have it flat bedded to the nearest dealer. Cost to replace the pump: $1600! In addition, the tech told me my valve cover was cracked. Cost to repair: $2000! I understand these two components are poorly designed and prone to fail but typically they fail at around 70,000 miles. Has anyone else experienced either (or both) of these premature failures? As I planned on keeping the car for at least 10 years and have tried to maintain it above and beyond the BMW maintenance schedule. I use Redline oil in the engine, transmission and differential. I also changed the oil at 1000 miles. I tried to contact BMW USA to see if I could get them to do a good faith repair or a partial rebate on the cost but received no response to my letter. Any advice on how I should deal with BMW? Or do I just suck it up and accept the fact that these cars are unreliable and very expensive to maintain?
