Water Pump May Develop Coolant Leak on BMW X5

Problem Description and Possible Solution

The low coolant light may illuminate and/or the engine may overheat as a result of a coolant leak from the water pump. The leaking pump will require replacement and the entire cooling system should be inspected for leaks as it is not uncommon to find multiple leaks on higher mileage vehicles.

Overheating can cause severe engine damage. If the engine begins to overheat it is recommended to stop at the first available location and have your vehicle towed to a repair shop.

While stuck in traffic on a cool evening, I heard a loud pop and then while smoke or steam poured out of the engine. There was no warning from the temperature gauge. The cause of the problem was the reservoir canister which cracked and spilled out the remaining coolant and water.

Before this event, the dashboard only sent out one or two warnings regarding "check coolant level". I replaced the coolant and water. The engine has had two episode in which it started to sputter and run sluggish. It sent out a "Service Engine Soon" light. The X5 couldn't drive faster than 60 MPH and had a loss of power. Once the light shut off, the car returned back to normal.

Currently, I have to replace the coolant/water daily. It requires less than previously, but this must be checked daily. I already went through 2 gallons of coolant/water in two weeks. The light has indicated the coolant level is low.

Any suggestions what is going on with the engine. There is also a slight puddle of fluid underneath the vehicle. It seems to have a small leak somewhere. Hopefully, this leak is not the water pump. I'm not sure where to start as cost is a major issue right now.
The 2008 X5 3.0L started to sound like a jet engine with the super loud fan noise.

I thought the car was going to blow up.

Took the car in for repair, and luckily the engine hadn't overheated yet.

They found that the water pump was faulty, which caused the wiring to burn out, and caused damage to the fuse box.

If I had driven the car any more, it would have caused significant damage to the engine of the vehicle.

After the $1400 repair for water pump, thermostat, and the fuse box wiring, I found out there is a recall for only the V8 - V12 engines for this car???? (just type in "2008 BMW X5 water pump recall" on google)

I find it very strange that they would only recall the other engines that are not as popular when the 6 cylinder has more cars on the road.

Also, I just found out there is another recall "DMTL Pump" which causes the engine light to turn on and cause system failures. (This prevented me from getting my emissions passed)

After speaking to several BMW reps, they informed me the recalls only occur when a sufficient number of people complain about it. 1-800-525-7417

Hopefully, we can get enough people with the problems to raise this issue with BMW.
My 2009 (year not listed in the box above, so I had to pick that 2008) X5 just had the water pump replaced yesterday (Nov 31, 2013) as it started all of a sudden to produce loud noise from the fan blowing at the top speed the day before. I looked at the coolant and it was well below the min level; the car just had had a brake service a couple of weeks ago and I would assume they would have topped off the coolant. The cost of the replacement was over $1200. I wonder if the low coolant level cause the pump to fail. I was told there was no leaking of coolant. Haveing read many reports on the web about the X5 water pump problem, I think it's a shame that BMW's product should have this persistent quality problem. Is there any way we can bring the complaint to the BMW management?
water pump and thermostat had to be replaced- car overheated
replaced water pump and thermostat and hoses but coolant is currently leaking
Cooling fan started running at top speedn, high temp warning came on, car went into safe mode and reduced speed, got home and parked it. My mechanic picked up today and let me know we had low coolant, water pump is bad. Part is made out of plastic
My car only has 33000 miles and already has this problem.It cost me too much money to have it replaced.
My x5 bmw 4.8i leak green liquid
Check engine light came on and I took it in to get checked. They noticed that the water pump was about to come off and had to replace water pump. Seems a very common problem. Just glad engine didn't overheat and cost me more money. Should be a recall on this as if engine seizes while on highway it can be very dangerous.
waterpump bearing making noise coolent from sensor or expansiontank possibly a hose. needs a tune up
Same thing
water pump failure caused overheated engine and stranded on freeway!
Engine overheated was told water pump and circuit board to include thermostat a $1400 dollar repair
Engine light on warning and then big loud fan
2009 X5 for me. Was leaking coolant and light kept coming on. Water pump needed replacing. $900
2011 X5 3.5L twin booster 6 cylinder - 30,000 miles - engine overheated out of nowhere, reduced speed/prevented acceleration and immediately after stopped completely.

Needed new water pump, thermostat, hoses, screen, bolts, antifreeze system.... $1,700! Sounds much more expensive than the rest of you here, maybe because of location or year of service (April 2015).
Replaced water pump and thermostat on my 2009 X5 with only 41k miles. No coolant leaks, just overheated and shut down. Total cost including the tow was $1423.00.
The water pump failed on my 2008 BMW X5@ 47000 miles. There is a recall for 2010 and for those with other engines but unfortunately not mine. I have put in a complaint with NHTSA.gov. Maybe other readers can add their complaints too and force BMW to fix the problem. It costs approximately $1300 to fix
Coolant light came on and after filling coolant, noticed low idling engine. Turned out to need coolant pump replacement as well as some other tangential parts needing replacement.
X5 with 54,000 miles. Water pump broke....took to BMW....$1973!
