|---|---|---|---|---|
| Sep 2023 | POWER TRAIN | Oil leak. Smoke from the engine. Inspected by the local body shop, we were told that the leakage would probably come from cylinder head. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: No | Unknown |
| Aug 2023 | ENGINE | Had an slow oil leak. The cylinder head was cracked in my engine | Crash: No Fire: No | Unknown |
| Jun 2023 | ENGINE | Engine oil started leaking after I noticed smoke coming from the hood of the car. No warning signs, no check engine light, nothing to indicate any issues until this occurred. Took the car to the dealership who confirmed it was a cracked cylinder head which is now being replaced. | Crash: No Fire: No | Unknown |
| May 2023 | ENGINE | Driving down the freeway smoke started coming out of the hood of the car and into the cabin, no warnings or warning lights of any kind, got the car to the Mazda dealer to be inspected. The dealer told me it was 5 months out of warranty and would not be covered its a cracked cylinder head and oil had dripped/leaked onto the manifold causing the smoke. No smoke was coming from the exhaust so the crack only leaked oil to the outside of the cylinder head. There is no oil in my driveway so it happened that day on the road. This is a manufacturing error that Mazda won't take responsibility for. | Crash: No Fire: No | Unknown |
| May 2023 | ENGINE | When driving I started to smell a burning oil or rubber smell inside the cabin of the car. When I stopped I could see smoke coming from under the hood. When I was able to park, I opened the hood and could see smoke coming from the engine. There were no warning lights displaying on the dash, no leaking fluid from under the car. I did not feel safe continuing to drive the car without having it seen, so I took it to the closest Mazda dealer service. After inspecting the issue I was told there is a cracked cylinder head that is leaking fluid into the engine and the exhaust and I would need a brand new engine. The service manager said this is a known issue with the 2018-2021 Mazda CX-5. Unfortunately, the warranty that would cover this expired in April 2023 (at the time of writing this, it's May 1, 2023). It should be noted that my CX-5 is only 5 years old with ~37,000 miles on it. I was told by the Mazda service manager that the car is not safe to be driven in this condition and would have to stay in their possession on their lot until I decide if I want to have it fixed. | Crash: No Fire: No | Unknown |
| Apr 2023 | ENGINE | Crack in cylinder head at 25k caused oil to leak and engine to smoke while driving. No warning lights came on. Dealership replaced the part but how do I know it won't happen again? Mazda knows about this but has not issued a recall or extended the powertrain warranty to cover this known manufacturing defect. | Crash: No Fire: No | Unknown |
