One problem related to other fuel type engine turbo-charger has been reported for the 2011 BMW X5. The most recently reported issues are listed below.
Only after about 10 minutes of driving in the neighborhood, we got a warning "engine hot, drive moderately" then a few minutes later, it said to engine hot, and to stop the car immediately. We had to pull the car over and after engine cooled a bit, take our 2011 X5 to the nearest shop in an emergency. The shop mechanic had to replace the water pump and said that it is a common problem with BMW X5, even though we only had 71,000 miles. I looked online and there is a recall affecting water pumps for BMW X5 2011 (engine and engine cooling:engine:other fuel types:turbo-charger recall number: 11v521000) but when I called BMW, it said that my particular engine is not recalled. The mechanic says this is unusual for such a new car to have engine overheating due to water pump failure, this should be investigated for safety issue.
