Three problems related to engine failure have been reported for the 2006 BMW 325. The most recently reported issues are listed below.
The contact owns a 2006 BMW 325i. The contact stated that while traveling 55 mph, the temperature warning lamp illuminated. The vehicle was taken to the dealer who diagnose that the aluminum bolts holding the engine melted and were sucked into the engine. As a result, the engine failed and needed to be replaced. The dealer mentioned that this was a known problem. The failure and current mileage was 144,300. . . Updated 01/30/13 updated 2/5/2013.
This vehicle has a magnesium engine block, and therefore uses aluminum bolts to fasten the head and the valve cover to the engine block. With normal driving, multiple cylinder head and valve cover bolts spontaneously snap off. This type of failure has the potential to disrupt the timing chain and loss of compression, leading to catastrophic engine failure.
Purchased new 2006 BMW 325xi on 9/27/2006 and auto had engine failure on 10/2/2006. Found to have defect in the spark plug which burned out the coil and damaged the valve. I am seeking advice on rejecting the vehicle. It is at the dealer.
