Hi, I bought a Mazda CX-5 -2019 with 55 thousand miles at 19,0000 last month from a Nissan dealership out of warranty. I have always heard a little chirping noise, but it is slowly getting louder. Someone shared what they thought was occurring is a CX-5 2019 car issue that is a costly fundamental flaw of this brand. Its related to particles that wear away prematurely and due to frictin and create a slippage in 3-4gear. As mentioned its costly and permanent. I am heartbroken to say the least, that I put so much money into buying the care and I love the vehicle but feel it is so unfair that the care was traded and a dea;er felt good selling it (most liey hearing and understanding the problem. I essance the care was cleared by there mechanics knowing it woult coast another $3000-5000 to repair. The Carfax data notes that this is an accident-free car that was maintained consistently. Itcame with new breaks and tires, has regular oil changes and one owner. Long story short...I was told to check into the Good Will Mazda program for support and/or the DYI fix to avoid the labor intensive costly repair of a full transmission. I am wondering if anyone has had to navigate this problem and am interested to know if the DYI fix works. Donna
