Two problems related to engine noise have been reported for the 2013 BMW X3. The most recently reported issues are listed below.
When at stop light the car stalls or when I'm at a stop sign stalls engine very dangerous and developed anxiety driving it, gust week oil can out back and odd engin sound making noise, it had to get towed but ira Toyota suckered me. They can't get in the engine to inspect it. I can't drive it on highways at all scared it will engine stop.
We experienced a complete engine failure while driving the vehicle at approximately 40 miles per hour on a city street. We received a "drivetrain malfunction" warning, something that we have received intermittently over the past year, which was previously diagnosed as a minor issue. We noticed a change in engine noise and performance, which was unusual. While attempting to bring the car to a BMW dealership for service, a "low oil pressure" warning came on and the engine quit approximately 10 seconds later. I was able to coast the vehicle into a parking lot, where we had it towed to the dealership. The dealership diagnosed it as a failure of the timing chain guides and advised us that the engine needed to be replaced. Thankfully, we were operating under the favorable conditions to safely stop the vehicle; however, the failure is sudden and potentially dangerous. Through research, we now know that this is a common problem with the engine for this particular year and model. We attempted to resolve the issue with BMW north America. They are aware that this is a common problem and were unwilling to provide any assistance.
