RE:RE:Who makes the most reliable new cars?
i doubt your read the 2020 study, likely you just read the conclusion.
There are marked difference between the CR study of 2020 and the Nov 29, 2023 study
Here is my interpretation:
CR 2020 report only studied only 2019 ICE and EV variety model year
- the 2020 study only looked at the day to day running cost, hence, the studied cars have no out of warranty cost nor include non billiable cost like naggy small issues that required owners to take their car back to dealer for no-cost fix. IE, cost of owner time
The 2023 CR study is a newer study and cover over +330,000 vehicles and a wider spectrum of car issues from naggy to big out of warranty battery replacement
Every year CR asks its members about problems they’ve had with their vehicles in the previous 12 months. This year we gathered data on over 330,000 vehicles, from the 2000 to 2023 model years, with a few early-introduced 2024 model years.
We study 20 trouble areas, from nuisances—such as squeaky brakes and broken interior trim—to major bummers, such as potentially expensive out-of-warranty engine, transmission, EV battery, and EV charging problems. We use that information to give reliability ratings for every major mainstream model.
Since it is difficult to have cost data relating to owner's naggy problem to their major out of warranty cost, the CR 2023 study instead reported problem count without associated cost statistics. However, it is a common sense to correlate the size of car problem count to the size of cost to fix those problems
i have already posted a case where the ioniq EV owner was quoted a out of warranty battery replacement cost of 50k CAD while a brand new ioniq EV only cost 50-55k. I have also posted many situation where the city idled their out of warranty EV buses because it would cost too much to fix them. Yes, cost of owning a EV is sweet when it's within warranty.
The studies also excluded comparison with used cars. There are lots of good used ICE can be had for under 15k CAD. A mechanical astute person could even find a very good used ICE for <5k. A 5k used car or a 20-30k CAD used EV and it won't be a tesla, you do the math. No astute home mechanic can diagnose the condition of an used EV unless a buyer willing to chalk out > $5000 for a pre sale inspection.
