Consumer Description

Started 2018 Mazda CX-5 and the engine was extremely loud and a ticking noise was heard. Brought it to my local garage (Charlies Garage) and it was determined that the lifters needed replacement. Garage told me that Mazda issued a Service Alert on November 22, 2019 (Alert # SA-012/19) and did not notify customers of the Valve Tapping or knocking noise from cylinder head. The Garage then told me that Mazda issued a Technical Service Bulletin on April 23, 2020 (Bulletin No. 01-006/20). Again, customers were not notified of the Tapping Noise from Engine Bulletin that was issued. There were no alerts on the dashboard of the car, no warning lights, or other indicators. If Mazda had notified customers, the car would have been fixed UNDER WARRANTY. I do have a video of the noise and if you let me know how to send that, I will.
