If this was the case you'd expect a noticeable difference between ICE cars and EVs in the statistics. According to the statistics, EVs are a mixed bag. For instance the Mini Cooper SE and Audi Q4 E-tron have very low defect rates (3.5-4%). Overall defect rates for 2-3 year old EVs seem to be close to that of ICE cars.

Since Tesla have very high failure rates they may be dragging the overall EV numbers down. So the sensible thing to do would probably be to look at reliability of EVs with the Teslas taken out of the dataset and look at what it does to the overall reliability numbers for EVs. I have a feeling it might nudge EVs ahead of ICE cars more clearly.
