Is the e-Skyactiv D 3.3 reliable?

The e-Skyactiv D 3.3 is an inline-six diesel with mild-hybrid assistance that Mazda debuted in the CX-60. It is a very recent engine: there is no in-service reliability data, and what is documented are software recalls (stalling, restarting, clutch) fixed at the official dealer.[1][2][3]

Is the 2.0 BlueHDi reliable?

The 2.0 BlueHDi is mechanically one of the sturdiest PSA/Stellantis diesels: in the samples available for its 150 to 180 hp versions, the turbo, DPF, EGR and injectors fail noticeably less often than on earlier generations of the same engine from before 2013. Its documented weak point is the AdBlue tank, a fault so widespread that Stellantis compensates affected owners without a definitive fix.[4][5][6][7]
