Telsa issues are resolved and the minor issues were early and any few larger ones were isolated and hyped. LEAF issues seem to remain for a long time and any software issues are permanent and never get updated until a new model. But clearly people seem to vote their choices in numbers.
Uh huh...
Edmunds got their drive unit replaced 3 times along w/battery pack + other stuff in their long term (30K miles in 17 months) S : https://www.edmunds.com/tesla/model-s/2013/long-term-road-test/wrap-up.html under Maintenance & Repairs. Their 1st replacement outright failed while accelerating on the the highway. HV battery pack got replaced along the way.
Took Tesla years to seem to resolve the DU noise issues:

Numerous other folks have gone thru multiple DU replacements in the first few years of S. From https://teslamotorsclub.com/tmc/threads/two-thirds-of-early-model-s-drivetrains-may-fail-by-60-000miles.58763/page-2#post-1279598 in Dec 2015
Of the vehicles that have been reported to the Plug In America Model S owner survey, 32% of the 2012 model year cars have had their drive unit replaced at least once, 27% of 2013's, and 18% of 2014's and so far none of the very few 2015's reported.
Although not apples to oranges, for context, the table at the bottom lists average problem rates for systems in cars in CR surveys during a 12 month window of time (shorter for latest model year): https://www.consumerreports.org/car-reliability-owner-satisfaction/car-reliability-histories/. I don't buy cars with below average reliability ratings unless there's a really good reason to.
The noise problems seem to have gone away with the -Q revision DUs, except some of them still fail (to deliver propulsion).
Now that folks are past their 4 year basic warranty, MCU and door handle problems are rearing their heads besides half shaft-issues: https://teslamotorsclub.com/tmc/threads/clunking-sound-is-costing-me-a-bundle-to-fix-out-of-warranty.93857/
https://www.edmunds.com/tesla/model-x/2016/long-term-road-test/wrap-up.html under Maintenance & Repairs sure had lots of problems. I can post about another 6-10 threads easily on various FWD and front door related issues. Here are a few for starters

Well, here you go. I am OFFICIALLY DONE - I have not had a single week with the car back without issues with the FWD. What I have noticed is that if the car is facing the sun even on a relatively cool day of 70-75 degrees, the door just doesn't operate properly. Here is a video (I've recorded several others on separate days, but have not had time to upload to youtube):

A whole bunch of Model X folks had been getting half-shafts replaced, sometimes multiple times: https://teslamotorsclub.com/tmc/threads/acceleration-shudder.74184/.
Model X ended up being dead last at https://www.consumerreports.org/car-reliability/10-least-reliable-cars/ vs. being middle of pack of bottom 10 the year before: https://web.archive.org/web/20170101002409/https://www.consumerreports.org/car-reliability/10-least-reliable-cars/.
I've seen some Model 3 DU replacements already besides other issues that have required a trip on a flatbed truck.
Examples of Model 3 DUs requiring replacement:

How many Leaf motor/gearbox replacements have we seen here before any reason despite now over 300K Leafs on the road since Dec 2010? I don't know the # off the top of my head, but I can safely say that here on MNL + the Leaf FB groups I"m on, it's in the single digits.
