> Tesla fell six spots from last year and now ranks third-worst (27 out of 29). The Model S dropped to “Below Average” this year, and its Overall Score is no longer high enough to be “Recommended” by CR. Owners reported suspension problems and other issues that included the extending door handle. (Please see chart below.) The Model X SUV remained “Much-Worse-Than-Average” for reliability, with ongoing problems including the falcon-wing doors and center display screen. On the flip side, the Model 3 sedan has “Average” predicted reliability based on owner feedback
Note that none of those issues appear to be related to the electric battery and drivetrain. They are design and manufacturing issues with systems that are present on ICE cars also. It's a demonstration that the goalposts of "reliability" are themselves shifting away from focus on the propulsion system.
Admittedly, ICEs have become incredibly reliable themselves over the last few decades. But there is an order of magnitude more complexity required to achieve that reliability in an ICE vs an EV.
