One problem related to coolant leaking has been reported for the 2012 BMW 328. The most recently reported issues are listed below.
April 2013, a warning signal on my vehicle notified me there was a need for coolant. I scheduled maintenance for 4/18/13. I informed them of the coolant warning and also inquired about recall notices. On 4/19/13, I called weber BMW myself to check the status, louie informed me there were 3 recall notices on my car that were apparent and needed to be repaired, and that they would need to hold my car until Monday 4/22/13. I picked up my car on 4/23/13 and louie informed me all the recalls were fixed and my car was good to take home. On 4/24/13, the coolant warning signaled again. That evening, my car began to exert even more issues than before! first the coolant warning, then warning telling me to drive moderately, then pull over immediately engine overheating. I pulled the car over, stopped the engine allowing it to cool down, and starting it back up, the car would not go over 17 mph. I contacted weber BMW for another service scheduled for 4/30/13. A representative from weber BMW contacted me on 4/29/13 and informed me louie advised I casually stop by to top off my coolant,â� and that should resolve my problems. I found this resolution skeptical, lazy, and knew it would not be adequate to resolve the issues with my car. I stopped by weber on 4/29/13 and the service adviser attempted to top off my coolant, when we both noticed the coolant spilling out of the other side of the engine (I emphasize spilling and not leaking). I was advised not to drive the vehicle. Louie called me on 4/30/13 to reported a hole in the part that was replaced per the recall causing the coolant to spill out. He let me know that the car would be ready next day 5/1/13 for pick up. I do not feel safe driving this vehicle any longer. I purchased this car 4/10/12, and it began showing issues of poor manufacturing just shy of a year, I only have 14,000miles on the vehicle.
