2008 BMW X6

Issue: 
On certain vehicles, long-term exposure to high absolute humidity and temperature, combined with high temperature cycling, may eventually degrade the propellant contained in the passenger-front airbag. This could cause the airbag to deploy with more force than normal. If the airbag inflator ruptures, fragments could be propelled toward vehicle occupants or cause damage to the airbag assembly, preventing its proper function. 
 
Safety Risk: 
If the vehicle is involved in a crash requiring an airbag deployment, the airbag inflator could rupture and create a risk of injury. 
 
Corrective Action: 
Owners will be notified by mail and instructed to take their vehicle to a dealer to have the passenger-front airbag module replaced. 
Note: The Canadian climate results in the propellant degrading slowly. This recall is being conducted as a precaution to address future risk. It is expected that all airbag inflators will be replaced before their function would be affected.

On certain vehicles, the auxiliary water pump (which cools the turbocharger after the engine is turned OFF) can overheat and fail. This could result in a vehicle fire causing injury and/or damage to property. Correction: Dealers will replace the auxiliary water pump. Note: Owners are advised to park the vehicle outdoors until the remedy is applied. Additional note: This is an expansion of recalls 2011-376 and 2012-008.

On certain vehicles, long-term exposure to high absolute humidity and temperature, combined with high temperature cycling, could eventually degrade the propellant contained in the passenger frontal airbag. This could cause the airbag to deploy with more force than normal. As a result, if the vehicle were involved in a collision that warrants airbag deployment, fragments could be propelled toward vehicle occupants, and the airbag assembly could be damaged, preventing proper function. These issues could increase the risk of injury. Correction: Dealers will replace the passenger frontal airbag module or inflator. Note: Canadian climate results in the propellant degrading slowly. The recall is being conducted as a precaution to address future risk, and is expected to replace airbag inflators before their function would be affected.

On certain vehicles, the wires going to the in-tank fuel pump may not have been crimped correctly.  An incorrect crimp could increase the resistance of the circuit which could cause the contact pin to heat and melt the surrounding plastic. This could potentially cause the fuel pump to stop working causing the vehicle to stall without warning, increasing the risk of a crash causing injury and/or damage to property.  Also, in a very rare case, a fuel leak combined with an external ignition source, could increase the risk of fire causing injury and/or damage to property. Correction: Dealers will replace the fuel delivery module.

On certain vehicles, the driver frontal airbag inflator could produce excessive internal pressure during airbag deployment. Increased pressure may cause the inflator to rupture, which could allow fragments to be propelled toward vehicle occupants, increasing the risk of injury. This could also damage the airbag module, which could prevent proper deployment. Failure of the airbag to fully deploy during a crash (where deployment is warranted) could increase the risk of personal injury to the seat occupant. Correction: Dealers will replace the front driver air bag inflator or air bag module, depending on the vehicle model.
