Disadvantages of the EHD engine
The most common complaints regarding the phase shifters’ quick failure;
Regular oil cooler leaks rank second in terms of owner complaints;
The electric vacuum pump motor is the weak point of the internal combustion engine’s start-stop system;
The thermostat, pump, and oil pump are not the best resources; using the incorrect oil frequently causes wear on the camshaft lobes.
