Subject: 2018 Mazda3 Exhaust Valve Spring Concern Safety Recall 1717K


On November 22, 2017, Mazda Motor Corporation decided to conduct a Safety Recall Campaign to address a concern with 2018 Mexico Built Mazda3 vehicles equipped with a 2.0L engine.

Concern Outline:

Certain subject vehicles may be equipped with cylinder head exhaust valve spring(s) with an incorrect specification.  The incorrect spring is smaller than specified part.  If the vehicle is used with the wrong valve spring(s), the valve spring(s) may break, and in the worst case could result in an engine stall.

There are a total of 144 vehicles involved in this campaign, and the number of affected exhaust valve springs is only 6.


Affected Vehicles:

Model Subject VIN range Subject build date range
2018 MY Mazda3 equipped with a 2.0L engine 3MZ BN**** JM 178705 – 181283 From October 6, 2017 through October 13, 2017


Action Required:

Beginning today, some 2018 Mazda3 vehicles equipped with a 2.0L engine must not be delivered to customers until the recall inspection and/or repair is completed. The inspection procedure will be posted on MGSS today. It is expected that almost all vehicles will only require an inspection. There are only 144 vehicles affected by this recall.


Use MGSS to pull your affected vehicle list.  eMDCS should display this recall by on or before Monday 11/27/2017.  Any affected vehicle will display 1717K in “Not Launched” status. “Not Launched” means that customer notification has not gone out, but the inspection and repair can still be performed and the recall closed. Once the inspection/repair is completed, the vehicle can be delivered.


Customer Notification:

All Mazda owners of affected vehicles will be notified by January 20, 2018.

Important Safety Notice: The National Traffic and Motor Vehicle Safety Act prohibits the delivery of any subject vehicle without performing the necessary repair for defects or failures. Failure to perform applicable recalls before delivery can result in extensive dealer fines and penalties from the Federal Government. Therefore, you must complete this recall for all affected vehicles in your inventory prior to delivery.

Additional details, including customer notification, parts and warranty information, and repair instructions, will be provided as soon as they are available on MGSS for your reference.

We apologize for any inconvenience this recall may cause your dealership and your customers.

Your understanding and support in carrying out this safety recall are greatly appreciated.

Because Driving Matters, Safety Matters. Your safety is important to Mazda.
