If you look at the YouTube videos where they breakdown the drive units, you will find out that claim EV's are much more reliable than ICE cars because they only have 1 moving part for the motor versus hundreds for an ICE is a lie.
The drive unit consists of a very big electric motor, a single speed transmission with a differential, and an inverter to make the AC power from the DC batteries.
You will see in those breakdowns, there's a lot of familiar things to break that you will see in an ICE. There's crazy amount of gaskets and seals to go bad, there's an electric oil pump to fail or leak, there's a water pump with coolant flowing in all sorts of scary places through and around delicate electronics, there are little heat exchangers/radiators to fail, plenty of bearings and gears to fail, and that darn inverter is a huge liability. The electronics to power electric motors are no where near as reliable as the electronics to run your PC, and PC's fail too, which most people don't believe is the case.
I seriously don't think a drive unit is any more reliable than an ICE, especially after my 2023 MS rear inverter just blew at 5K easy miles and bricked the entire car on the side of the road. In terms of repairs, they don't seem any easier to repair, especially since you have drop the DU for every little thing. With an ICE, you pop the hood, remove a few things in the way, and replace the failed part. And now the SC seems to be struggling to repair my car by messaging me they are taking longer than expected as they "address concerns related to the inverter replacement." Whatever that means!
