Infiniti QX50

Issue: 
On certain vehicles, the engine may not have been manufactured properly. As a result, the engine could make abnormal noises and a warning light may turn on. If you continue to drive the vehicle with these symptoms, the engine could fail. 
Note: This recall only affects certain vehicles equipped with 1.5 L or 2.0 L variable compression engines. 
 
Safety Risk: 
An engine failure could cause a sudden loss of power to the wheels and/or increase the risk of a vehicle fire. Both issues could increase the risk of a crash or injury.  
 
Corrective actions: 
The company will notify owners by mail and advise you to take your vehicle to a dealership to inspect and, if necessary, replace the engine. On certain vehicles, the dealer will also update the engine control module.

Issue: 
On certain vehicles, the wrong door latch may have been installed in the front passenger door. As a result, the automatic locking function won't work on that door. An unlocked door could open in a crash. 

Safety Risk: 
A door that opens in a crash could increase the risk of injury. 

Corrective Actions: 
Infiniti will notify owners by mail and instruct you to take your vehicle to a dealership to replace the right-front door lock assembly.

Issue: 
On certain vehicles, the front steering knuckles may not have been properly heat-treated. As a result, a strong impact (such as hitting a curb) could cause a steering knuckle to bend or break. If this happens, the steering wheel may become off-center or there could be a loss of steering control and a wheel could separate. 

Safety Risk: 
A loss of steering control and/or a wheel separation could increase the risk of a crash. A wheel that separates could also hit another person or vehicle. 

Corrective Actions: 
Nissan will notify owners by mail and instruct you to take your vehicle to a dealer to inspect the production date on the casting stamp of the front steering knuckles. Parts that are affected by this problem will be replaced.

Issue: 
On certain vehicles, the rear axle housings may not have been properly heat-treated. As a result, a strong impact (such as hitting a curb) could cause a rear axle housing to bend or break. If this happens, a wheel could be mis-aligned or there could be a loss of control and a wheel could separate. 

Safety Risk: 
A loss of control and/or a wheel separation could increase the risk of a crash. A wheel that separates could also hit another person or vehicle. 

Corrective Actions: 
Nissan will notify owners by mail and instruct you to take your vehicle to a dealer to inspect the production date on the casting stamp of the rear axle housings. Parts that are affected by this problem will be replaced.

Issue: 
On certain vehicles, the tire and loading information label may have printing errors. As a result, information on the label may be difficult or impossible to read. This could be confusing and lead to overloading of the tires, which can cause poor handling and/or a tire failure. Canadian regulations require this information to be printed clearly on the label. 
 
Safety Risk: 
Poor handling or a tire failure could cause a loss of control and increase the risk of a crash. 
 
Corrective Actions: 
Nissan will notify owners by mail and instruct you to take your vehicle to a dealer to inspect the tire and loading information label. If there are printing errors, the label will be replaced.
