I have 3 recalls on my vehicle. Two of them involve air bags and the the heat valve malfunction that could be very dangerous. I contacted BMW dealership and they mentioned they don't have any parts from BMW to fix two of them and have me on a waiting list for the third and will contact me, no time frame was given. I contact BMW North America and they direct me back to the dealership. So I'm driving a vehicle with 3 recalls and no time frame on when these will be fixed. I don't want anything happening while I'm in the vehicle since it is a 2007.

Right front motor mount bracket bolts sheared off. 3 of the 4 bolts were sheared off, and if the 4th had sheared before we got it to the repair shop this would have caused significant damage. If it had happened while driving this would have absolutely caused an accident.

- Lakewood, CO, USA

My 2007 BMW X3 (E83) front passenger side, "engine mount bracket bolts" snapped while driving vehicle. At least 3 of the 4 aluminum bolts snapped during normal vehicle operation which resulted in my engine resting on the vehicles water pump and eventually causing the water pump to fail. My mechanic noticed the snapped bolts when he attempted to install a new water pump. This is a major safety issue to have half your engine not properly mounted down and should be a factory recall. Just think of the damage a front end collision can cost with that part of the engine able to move freely. On the micro side it cost me a water pump. However it could have done more damage. Please recall this!!! numerous people online are reporting the same failure. It's a very dangerous and life threatening malfunction that could be avoided by BMW. The problem is galvanized corrosion between the different metals over time. The bolts are aluminum, and the engine mounts are magnesium-aluminum mix. I believe it is the magnesium that is causing the failure. There are a couple of fixes. 1-easy fix would be to take steel bolts and coat them with aluminum (the aluminum will slow corrosion and the steel will strengthen the bolt without giving way to galvanized corrosion). 2-other fix would be to make the bolts of the exact same mixture as the engine block (magnesium and aluminum) not just aluminum. The bolts still wont be as strong as the steel (aluminum) coated bolts.

When I pulled the cover plate off leading to the engine mount on the bottom right side of the engine, a sheared bolt fell out. As I search to where it came from I noticed it was one of the four bolts holding the engine mount to the engine. One thing to mention about the bolt is that is made of aluminum. It seems completely inadequate for a high stress area like an engine mount. I cannot tell you when exactly the bolt failed, likely in motion at some point between 70K and 80K miles.

Driving with 85000 miles on it and it just jumps when you push the gas. Hops like a bunny. Then it takes off like a race car...which is dangerous if a car is in front of my and I slam into them. This problem has came and went over weeks now. Had codes checked. There are no vaccum leaks or anything. I am not the only one having issues with this. Its dangerous and unacceptable of BMW.

While driving on interstate 72 in Illinois, we noted a low coolant level light. Checked the owner's manual, and it stated that this was not a major issue, but we should check it at the next opportunity. Coincidentally, the other party we were traveling with asked if we wanted to stop for coffee at a location 1.5 miles off the interstate. When we stopped, the low coolant light went off. Before getting back on the road, noticed that coolant was dripping from the front right side of the engine. A repair facility was nearby, and they investigated the leak and determined that it was emanating from a crack in the water pump. Also determined that the cause of the crack was the engine sagging. Further investigation determined that a lower engine mounting bolt was missing entirely. This was replaced along with the water pump, when the engine was jacked back into proper position. At this point it was discovered that the upper mounting bolts had sheared off inside the engine. This is a serious issue. We were one mounting bolt away from the engine sagging excessively, likely causing drive train seizure.

4 motor mount bolts were sheered. Took to dealership due to coolant leak and found that engine had become unmounted and was sitting on water pump that was cracked and causing the leak. I had noticed vibration but was not sure what it was. Over $2000 repair bill. This seems to be a common problem with this model BMW.

Engine mount bolts sheared off at the head causing engine to fall onto subframe.

I was driving on the interstate, exiting an off ramp, decelerating in speed when the engine died, the car stalled and I lost power steering. This very same thing happened 5 weeks prior while I was on the interstate traveling 60 mph.

2007 X3 3.0si 76000 miles. While performing an oil change, user noticed oil drain plug not aligned with opening in stiffening plate. Removed plate and M12 bolt fell out. Upon inspection, all passenger side engine mount bolts have been sheared off or fallen out. This vehicle has never been in an accident and is driven conservatively. Researched on-line and found that this is not an isolated incident. Prolonged vehicle use with sheared engine mounting bolts could cause drive-line failures potentially resulting in accident, injury, and/or death.

- Frederick, CO, USA

6 out of 8 of my motor mount bolts were sheared or broken in half. This is a common BMW problem with the N52B series BMW engines and BMW does not take any ownership of this obvious design or manufacturing flaw. This causes a very unsafe driving dynamic in that the engine is no longer held securely in place.
