One problem related to transmission not go into gear has been reported for the 2004 BMW 325. The most recently reported issues are listed below.
I owned the car for a year before it started giving me problems. It first gave me a problem changing from reverse to drive. It slips and wont go into gear. The most dangerous is when im turning a corner and the car puts itself into nuetral. At this time it is not driveable and I've researched it and it is common for this vehicle but I don't understand why there isn't a recall. Its dangerous! ive taken it to a mechanic and for a second opinion at BMW. The cost to repair my car is over $5,000, if I would have known that I would have bought the newer BMW. Now im without a car waiting to get approved for another loan just to pay for repairs.
