My battery failed after only 3K miles

It’s not even marketing. It’s ElonHuffers hearing what they want to hear from:
1) A comment made years ago about research into cell chemistries by Jeff Dahn that could pave the way toward a pack with that sort of longevity
2) A Tesla tweet in 2018 showing the internals of a drive unit that was tested on a bench to the equivalent of a million miles and stating this was an internal endurance “target”.
Tesla has never marketed a million mile drivetrain. People just hear what they want and think those two things mean “every Tesla battery and drive unit will last a million miles,” which is absurd.
That IS absurd. I'm expecting at least *THREE* million miles out of mine. If a car can't drive around the earth more than 100 times what good is it?
This "million mile drivetrain" nonsense has been going on further back than 2018. Back when Model S drive units were getting frequently replaced before making it even to 30K miles, the guy at Official Tesla Model S thread - Page 347 - My Nissan Leaf Forum in 2017 made this claim:
"It is also why Elon said that any Teslas made since May/June 2015 should have a 1,000,000 mile drivetrain."
Looks like he posted basically something like that here in 2015!
When will there be Zero drive-unit issues/replacements?
I live in the Bay Area and an employee told me that early Teslas had a spline issue relating to it being too small for the load and that they engineered a larger spline. Ive had one DU replaced (at about 5000 miles) and am having issues again and going in to discuss another replacement (now at...

Of course that guy never answered, so I did at Official Tesla Model S thread - Page 348 - My Nissan Leaf Forum. A few weeks later, I posted Official Tesla Model S thread - Page 348 - My Nissan Leaf Forum with links to some more BS.
Update: One my links in the posts I pointed to is dead, but here's a copy of it at Tesla Touts Million-Mile Powertrain - HybridCars.com, from 2015.

I will do that, Rich. My service appointment isn't for 10 more days. At this point I am just not driving the vehicle for fear of being stranded. I have asked for a loaner vehicle but so far just crickets.

Indeed. Here are two out of warranty 3s that didn’t even make it to 200K miles on their original packs.
Failed Model 3 HV Battery - Out of Warranty - DIY
I am currently facing an interesting problem that I thought might be worth sharing with the community. A few weeks ago, I bought a clean title Model 3 LRRWD with FSD and 143k miles for $23k. The main catch was a HV battery with significant imbalance (one brick was 3.50V with all others at...

Uber Driver's Tesla Model 3 Battery Dies After 120,000 Miles In 15 Months
An Uber driver covered more than 300 miles a day six days a week in his 2019 Model 3 SR+, making two Supercharging stops per day.

So, someone on a Bolt group a claimed "One Tesla owner has reportedly driven his Tesla Model S over a million miles, according to CleanTechnica..."
I found How Long Do Electric Cars Last? This Tesla Has Gone 1 Million Miles!. But from Tesla Model S to clock one million miles and Tesla Model S owner passes incredible one million mile mark, but may switch to Lucid, he's been through several packs and drive units. The former says:
"However, it’s understood the vehicle has been through three battery packs and eight electric motors since 2014 – with the first motor lasting nearly 800,000km, and each subsequent motor failing at around 200,000km."
Point me to any marketing by Tesla claiming a million mile battery life. I think Elon said that the Model 3 packs should last 300-500k miles, but there is no official marketing on the battery life.
That was a Model S. There are some known flaws that have been resolved since that vehicle was designed.
I'm not saying the Model 3 will last a million miles, but it'll be interesting to see in the next 5 or so years the longevity of early Model 3s.

To be fair though, both of these cars were sold used, so their history was "washed" and we don't know how they were treated. The second was then used for Uber and supercharged twice a day 6 days a week.
They still both lasted over 120k miles. Plenty of ICE vehicles need major repairs before hitting that mileage.
My 2019 M3LR battery failed in March around 40k miles and Tesla replaced it with a refurbished pack. It’s like any other car despite Tesla marketing it otherwise. It’s going to fail at some point.
Only pain point is that compared to an ICE vehicle I have limited options in terms of diagnostics or repairs and I’m completely dependent on Tesla. Ignore the marketing BS (it’s as true as Elon’s timelines).
Cross your fingers and hope Tesla will give you a decent replacement pack. Someday we might actually be able to get a new pack to replace it from someone more transparent than Tesla.

If you buy known reliable vehicles in Consumer Reports from automakers that have a pretty good track record across most models and model years (e.g. Toyota or Lexus), the chances aren't high that they'll need major repairs before 120K miles.
IDK where people get this BS from. Let's look at the facts. The current MY/M3 battery packs are basically warrantied for 1000 cycles at most. There's some evidence that the packs may last as long as 1500 cycles. A cycle is one complete charge cycle. Let's be generous and assume that means the rated 330 miles on a MY LR today (which isn't really true as we all know). That's 330x1000=330k miles. That's 1000 cycles. If we assume 1500 cycles then it's 330x1500=495k miles. That's not real world though. Figure 80% efficiency on average, so that 330 miles becomes 264 miles. So, real world 264x1000=264k miles. At 1500 cycles it's 264x1500=396k miles. Nowhere close to 1mm miles on average. Sure, there are always outlier cases - but those are exceptions not rules. These are the expected averages for how long the battery packs will last that are in use currently. The only exceptions to this would be the LFP battery packs in the M3 RWD - which will last a good bit longer since all LFP battery packs offer much higher cycles than comparable NCA/NCM packs. If you want any chance of having any pack last anywhere close to 1mm miles at present - buy a BEV with an LFP pack. LFP packs will typically last 3000-4000 cycles in comparison. Given LFP packs are less energy dense and therefore typically offer few miles per charge cycle - so the multipliers will be a bit less - but still - with 272 miles on a M3 RWD - that's 272*3000=816k miles or 272*4000=1,088k miles. Real world 80% efficiency would 652k miles with 3000 cycles or 870k miles with 4000 cycles. Getting closer to 1mm miles - but still not there - but the chemistry in LFP packs is likely to provide more durability than any NCA/NCM packs today at least.

to follow up with everyone, the service center did replace my battery. They had the car for 2 full days. I think it is a new battery but I’m not sure how to verify that.
Everything seems to be working correctly thus far.

I don't have a source, but I thought it was 500 cycles. I remembers hearing this multiple times over the past few years.
