Mazda Mazda6

Issue: 
On certain vehicles, the fuel pump could fail. If this happens, the engine may run rough or may not start and the check engine light may turn on. This could also result in a sudden loss of engine power while driving. 

Safety Risk: 
A sudden loss of engine power while driving could increase the risk of a crash. 

Corrective Actions: 
Mazda will notify owners by mail and instruct you to take your vehicle to a dealer to replace the fuel pump.

Issue: 
On certain vehicles, a software error in the Powertrain Control Module (PCM) could cause the valve clearance adjuster not to work properly. This could result in internal engine damage. If this happens, the engine may misfire and lose power. In the worst case, the engine may stall while driving without the ability to restart it. The malfunction indicator light (MIL) may also turn on in the instrument cluster. 

Safety Risk: 
A sudden loss of engine power could increase the risk of a crash. 
 
Corrective Actions: 
Mazda will notify owners by mail and instruct them to take their vehicle to a dealer to update the PCM software.

Issue: 
The front cross-member may rust due to a manufacturing defect. This could affect handling and cause reduced steering control. 
Note: This problem only affects cars registered and operated in areas of heavy road salt usage during winter months (Ontario, Quebec, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland & Labrador), 
 
Safety Risk: 
Reduced handling and steering control could increase the risk of a crash.
 
Corrective Actions: 
Mazda will notify owners by mail and instruct them to take their car to a dealership to inspect the front cross-member and install a drain hose. Depending on its condition, the dealer will install a reinforcement and a wax coating, or replace the front cross-member. 
Note: This is an expansion of Recall 2018-504.

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 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. Additional Note: This is an expansion of recall 2018-040.

On certain vehicles, the passenger 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 passenger airbag to fully deploy during a crash (where deployment is warranted) could increase the risk of injury to the seat occupant. Correction: Dealers will replace the passenger frontal airbag inflator. Note: This recall supersedes recalls 2013-112 (Mazda Recall 6913D), 2014-245 (Mazda Recall 7714F), 2015-624 (Mazda Recall 9015L), 2016-259 (Mazda Recall 9416E) and 2017-011 (Mazda Recall 0617A).
