Are there any statistics out there that can make a comparison like this? I know there’s a comparison like this for vehicle fires and EVs came out way ahead
If these stats are hidden they shouldn’t be, all statistics should be able to be known
Here is a dependability study in the US

Doesn’t really answer your cute question, but it’s still info.
That kinda study sounds like it’s ripe for some serious variability. Idk if you’d ever see a study like that unless the automakers themselves released it.
The problem is similar. Engines can have a bad seal, a crankshaft not right. These get replaced.
Batteries as a hole don’t just fail. A cell goes bad. We don’t have easy methods to replace the one.
At this early stage of EV, this needs a little regulation I think. Currently batteries are made as cheap as possible to make the car as cheap as possible, but this also means they’re a monolith by design. Batteries need to be designed to make them modular and more easily replaceable. With some kind of size/weight/harness regulation, all the car designers could start to look into designs that allow swapping them out.
The rate of Lemon law returns is public abs know. Toyota is all time king 1 lemon 🍋 per 2029 cars sold. Tesla is at 1:1553. GM 1:78 cars. lemon index
Ahh, but the fires! My second cousin knows a guy who’s girlfriend has a sister who saw an EV catch fire.
/sarcasm
I’ve also seen a gas tank blow up. It’s scary as hell.
Well you have the Audi 2.0T with the damaged piston rings, BMW motor N47 damaged distribution chain, VW and the DSG dry oil crankcase, Renault and the disastrous electronic problems with their 2.2 diesel… This is just a short example of disastrous models that were a nightmare for their owners.
https://www.truedelta.com/car-reliability has car reliability ratings, though not specifically about engine failures. Good luck
Important distinctions from new that might make the comparison less relevant.
ICE cars typically have relatively short warranty periods after which repairs are all on your dime.
EVs more typically have 8 year 100k+ mile warranties on battery and drivetrain so battery failures at cost haven’t been very prevalent yet. At the same time, the battery reconditioning business hasn’t really needed to expand because most cars haven’t timed out of battery warranties.
Other important distinction is that the ICE engine reliability is at steady state more or less. EV battery technology has already drastically evolved over the last 5 or 10 year period and should be trending even more reliable every year.
A typical drivetrain warranty for an ICEV is 5 years. Some are 6, some are 10 years.
But what does that have to do with the comparison? A failure is a failure, no matter who pays.
It depends on the brand. A Toyota engine lasts longer than a Tesla battery without major repairs, but not necessarily longer than a BMW or VW battery.
this is underrated comment. A lot of times I read something like bmw, Kia, non-Toyota has engine failure at 70kmiles . When comparing reliability to ICE/hybrid: Toyota should be the benchmark. Time will tell; but I think a Toyota Corolla, Hilux, etc… will outlast most EV .
A Toyota engine lasts longer than a Tesla battery without major repairs, but not necessarily longer than a BMW or VW battery.
It would be lovely if you could back any of that up with data. Like seriously, even one of those claims.
So we’re comparing an engine in one vehicle to the “fuel tank” in another…
ADAC statistic (2023) for how often cars need roadside assistance (in german, but you can probably make out what the various graphics/tables mean or run it through google translate)
https://www.adac.de/rund-ums-fahrzeug/unfall-schaden-panne/adac-pannenstatistik/
Key numbers:
Cars with need for roadside assistance (per 1000):
ICE: 6.9 total (of which: 2.5 due to 12V battery; 1.6 tires; 0.5 starter/lights/ignition; 0.6 keys/locks: 1.3 motor/motor management/high voltage system…and then various positions at 0.1 each for chassis, drive related systems, brakes and ‘other’)
EV: 4.9 total (of which: 2.5 due to 12V battery; 1.1 tires; 0.6 starter/lights/ignition; 0.2 keys/locks: 0.2 motor/motor management/high voltage system…and then various positions at 0.1 for chassis, other drive systems, brakes and 0 for ‘other’)
(I highlighted the block “motor/motor management/High voltage system” whicc is probably what you’re intersted in. Effectively ICEs break down 6-7 times as often due to issues in that area)
I bought an EV, and I have to hear questions, jokes etc at first. THey died down as all of those people have car repair issues, or engine failures (new truck), etc.
Then I’m bombarded with commericals on tv for car repair. Ads in the mail for fluid changes, etc.
It’s so clear and blunt that it’s like asking for stats to show that the summer is hotter than the winter.
Complete engine failure is quite uncommon. The question is about complete battery failure, I hope would be the same uncommon, but no actual stats or observations
