Is the 1.8 TCe reliable?

The 1.8 TCe (M5P) in the Alpine A110 and the Mégane R.S. IV has no documented endemic faults. What has been published are recalls for the A110: the oil pressure solenoid valve (2019) and the fuel pump (2021 and 2023). We have found no recalls or complaints about this engine in the Mégane R.S.[1][2][3][4]
