CSP08 - NOTIFICATION OF CUSTOMER SATISFACTION PROGRAM CSP (08) – 2019 MAZDA CX-5 DIESEL ZERO COST MAINTENANCE PROGRAM: As a way to show our commitment to customer satisfaction and loyalty and to differentiate the launch of the 2019 Mazda CX-5 Signature SKYACTIV-D, Mazda designed the "2019 CX-5 Signature SKYACTIV-D Zero Cost Maintenance Program". This program was announced to all dealers prior to the sale of the 2019 CX-5 Diesel. Unfortunately, some customers were charged by Mazda dealerships for their scheduled maintenance services. This CSP08 was created as a reminder for dealers to easily track the Zero Cost Maintenance Program. Affected VINs will now display CSP08 Zero Cost Maintenance Program when running a Warranty Vehicle Inquiry. This program provides: Four (4) factory scheduled services which are required during the first two 2 years or 30,000 miles, whichever comes first, at zero cost to the customer for all 2019 CX-5 Signature SKYACTIV-D vehicles (excluding fleet rental vehicles). Allows the Mazda dealer to provide a premium service experience to our CX-5 Signature SKYACTIV-D owners, and builds a positive, lasting customer experience. Please refer to the Warranty Information as well as the Sales and Service Checklists that will be posted on MGSS by December 21, 2020. Owner Notification: Customers will be emailed in late January 2021 reminding them of their Zero Cost Maintenance Program. As a reminder, CSP programs are not subject to the Missed Recall Report but should always be reviewed to see if they apply to the customer concern if a vehicle is at a Mazda dealer.

This may be caused by the rear brake pads not having the capability to remove the rust from the rear brake discs. The red rust accumulated on the discs is exposed to high temperatures during braking, and consequently the rust turns black. As the black rust is too hard to be removed by the brake pads, the rust progress is accelerated, resulting in the grinding noise.
