The battery yes. Also, an electric motor is simple mechanically, but it is more complex than it looks on the outside. There's a lot going on in their design, and the manufacturing process is complex as well, especially if you need it to be efficient.
ICE engines have larger complex elements that can fail for more reasons, but the most complex part is just this big block that they pour into a mold. After that's done you just have to mount all the little components onto it that the suppliers have refined the tolerances on for at least 20 years.
But the ICE and the electric engine are just peanuts compared to the material cost of producing these huge batteries.
