MotorTrend reported the same problem.. they've already had it replaced twice.

Also, engine replacements on new gasoline vehicles run around $10k.
It's an interesting question actually, are Tesla motors only really serviceable as a unit? That could be bad news. A new gasoline engine might be $10k, but 99% of the time you just replace a belt or a pulley or a seal, or take off the top and do some machining for a few thousand.
If I think about it, no example comes to mind where I would be okay with paying much much more for something because the relevant technician says "I'll be easier for me if you buy a new one instead of me fixing this."
As another example, amputating a limb is relatively easy as surgery goes, but it will cost you your limb and you would probably prefer that doctors not do it for their own convenience.
The sum total of amputation is much harder than fixing the limb, assuming it's possible. Yes, it's easy for the doctors, but it's hard for you.
If fixing mold in a house is cheaper than building a new house, that's telling you that it's easier overall. It might look harder, but that's because much of the difficulty of building a new house happens off-site, in the felling of trees, mining of gypsum, fabrication of pipes and wires, etc.
If Tesla is doing warranty replacements instead of repairs it's not because it's "easier" in the sense that the technicians do less work at the expense of the company, it's because it's "easier" in the sense that it's less effort and money in total.
Even the rather unreliable MultiJet engine I have in my car has had a total maintenance bill of around $2000 over 70k miles. This was for an EGR valve that got stuck and a timing chain.

With an average labor per hour cost of anywhere from
80 to 120 dollars, you're probably looking at anywhere
from 1280 to 1920 for just labor. It will probably
take two techs two days to perform the work. Plus
the cost of the parts needing for mods, if I had to
give you an educated guess I would say you're looking
at paying anywhere from 1500 to 3000.Obviously some cars a cheaper, but I wouldn't want to be swapping engines in a BMW or Merc (competitors for the Model S)
Of course, the engine in the Model S is clearly a high performance engine too.
It's worth noting a replacement stock 3.6 VVT engine for the Wrangler is exactly the same price.
I've had my Model S since December 2012 (one of the first production models in the state of Georgia) and have had no major issues with it. I've only ever had proactive maintenance (12v battery system replacement, coolant pump upgrade, and improved sealant on the sunroof), all of which I haven't paid a dime for. They even provided loaner vehicles while they worked on it. I've driven it up and down the East Coast and a 260 mile straight shot from Atlanta to Savannah.
I've heard similar stories from most other owners. It is a tremendously easy car to own, as you barely have to do any work on it. Yes, cases like this will happen. But no different from any other car out there.
- Voltage / Current differences.
- Abstraction, for safety, testing and debugging purposes.
It has a large, high voltage battery that could easily be stepped down (and in fact is, since it charges the 12V battery), and yet a separate 12V battery is required to power the electronics to start the car.
Since the 12V battery is only used to power the electronics (the high volatage battery powers the starter motor), it is very small and consequently, drains quickly (a few weeks) if the car is not in use. I don't drive much and regularly find it dead when I try to drive somewhere.
The upside of it only being required to power the electronics is that I can (and regularly do) jump start it with a NiMH remote control car battery.
I understand that if the high voltage battery goes flat in a Prius, you're somewhat screwed, which is perhaps why they don't allow it to power the electronics for starting, but it's still a pain.
Disclaimer: this is an older Prius, newer models may be different
Battery bulk current handling capacity is provided by bulk lead in the plates and copper wires. Its extremely cheap to build a lead acid battery that can momentarily squirt out a thousand (or so) amps to start an engine on a cold winter night. Maybe $100 or so.
Unfortunately power converters / supplies of all sorts scale at a higher than polynomial rate. So although a 20 amp smart battery charger might only be $50, a similar power converter capable of 1000 amps peak starting currents might be way over $2000. Thats about 10KW and thats about the right price for non-industrial non-automotive inverter hardware so its probably higher cost.
The total system cost to provide momentary 1000 amp starting currents is minimized by a $50 charger and a $100 battery rather than a $2000+ inverter.
My wife has one and I'm slightly jealous, I know ham radio guys who've spliced in inverters to run their entire house off the prius, using it as a stationary generator basically. There have been articles in QST magazine. Anyway one issue they and everyone else runs into is the primary battery is physically disconnected from the world until the boot up self tests pass. Leakage current to chassis, stuff like that. Until the tests pass, power is not connected by the giant relay. So its chicken and the egg time, where how do you get enough power to run the self tests of the electrical system if the primary battery isn't connected until after all the tests pass? So you need a secondary battery thats never physically disconnected, the 12V lead acid traditional batt.
Now an excellent firmware question is why not have the firmware self test and partial boot the car every 6 hours to top off the 12 volt battery for 5 minutes? Probably some mechanic who thinks the car is off will manage to set it on fire by not being careful while replacing the battery or something like that. "Oh of course the main power cables are powered down, the whole car is powered down... err... whoomph" and then you need a new car and mechanic.
A design change to connect the 12V to the primary battery would then mean routing even more junk thru the primary battery compartment. There really is no perfect solution.
(Have to reply to mikeash as an edit. Yes I researched this after your comment and you are correct and MG1 is powered from the HV not the 12V to start, I did not know that. I knew it charged the HV and helped out at full throttle, along with MG2 that does "most of the work".
Anyway the TLDR summary still stands, from a scaling perspective there is an economic crossover point at a surprisingly low current, at least around the 90s's to 00's when this was designed, where its much cheaper to use a battery/charger than a really beefy inverter above a certain (medium-ish) current level. Someday that'll probably change as semiconductors advance and that crossover point becomes 50 kiloamps or something.)
As for topping off the 12V battery every so often, I don't think there would be much point. Most people drive their cars at least once every couple of weeks. If they don't, a cheap trickle charger will keep the 12V system happy while it sits idle. No point in adding equipment to solve a 0.01% case that's easily solved by the people who need it.
http://irobin.org/prius/startup/startup.html
The required 12V startup current for a Prius turns out to be surprisingly low. The author measures it for a 2005 model directly at around 30 amp (with one test showing a brief spike to 60 amp).
Based on this, I bought a pack of 10 5Ah sub C NiMH batteries for jump starting (unfortunately there is no outlet in my car park for a trickle charger).
Edmunds also seems to have had a long history of writing negative Tesla articles, oftentimes ignoring any positive aspects of the car in favor of oddly nitpicky complaints. See http://cleantechnica.com/2014/03/22/hatin-tesla-model-s-seem... Some have speculated that they might have a hidden agenda when it comes to Tesla, though obviously that's very difficult to prove one way or the other...but it certainly seems odd that nobody in the Consumer Reports survey experienced a single drivetrain failure while Edmunds went through three in a row.
Let alone the fact that many early adopters, if not the majority, are far less likely to complain about issues because they don't want to question or be questioned about their choice.
I am still waiting for the their 35k/40k/etc car. It will be very interesting to see their quality control issues with a near mass production car. Right now they are still down in the uber luxury levels of production and costs.

Consumer reports has a reliability rating of "average" on the Model S, and according to the Tesla forums themselves, the Model S was on the list of "Used Cars to Avoid".

It's a great car, I'm sure, but hyped to no end.
I'm not a fan of the Musk/Tony Stark schtick, or of SpaceX, or the hagiographic treatment he receives from the technical press, but I am a fan of Tesla as a carmaker.
Yes, there's a downside, which is out-of-warranty cost, and ultimately resale value. It's both a science experience we are funding here, and a public company. I would love to have seen some hard numbers from the stated financials about warranty costs, and expected future warranty costs.
I think it's a good question to ask -- is the longer term service cost of the car understood? Maybe we're just starting to get to that point, but I'm not sure the data is really out there. I do expect of any company that Tesla would be the best at predicting their long-term performance and costs.
It's one thing if the car isn't perfect, it's another if it becomes a maintenance nightmare. That could happen only outside of warranty, and not even directly impact their expenses, but it ultimately does impact sales. I would expect if there's an issue that Musk has discussed it at length already. This clearly isn't new.
I don't like the scaremongering about the cost of this repair. Did they even ask Tesla how much the repair would cost, and they refused to answer? It certainly doesn't say that they even asked the cost. I doubt it would matter, but I'm sure there's a law that they have to disclose the retail cost of the repair.
I know car reviews rarely quote the CEO, but for this specific issue of drive train, I think it's worth getting a quote from the company in the article.
Or it could be just growing pains, I suppose. But I've always been critical of Tesla's (and others') reckless attitude towards excessively long hours.
It's interesting - I bought a brand new Nissan Qashqai recently, and I HAVE to do an annual inspection to keep the warranty, regardless of the condition of the car. Basically after a year they will look at it, say "yep, it still works" and charge me $300 to stamp my warranty booklet.
I love how they (and most) rationalize skipping this service (aka maintenance is for suckers). The more time a trained mechanic spends under, in, on and thinking about your car the better. Especially when it's a techno-feast such as the Model S.
It's a grand experiment but I don't think the market for $70k assets that lose 90% of their value in 5 years is going to be too hot.
Remember that an asset is not the same thing as a store of value. A store of value can be an asset, of course.
The right to own a car for only 10 years has been bid up to about that. You can find cars with COE with less than 5 years remaining, that are still worth multiples of their non-Singaporean value. People will get into debt to drive a car.
Singapore has shown that restricting the supply of vehicles will drive the price higher. Yes, owning a vehicle is extremely expensive in Singapore and many in that economy are willing to pay the price (by definition since it's an auction based system).
I believe your parent was pointing out that the depreciation of the Tesla appears to compare very poorly with alternative vehicles, and potential buyers are unlikely to choose such an expensive option when there are far cheaper alternatives available. Singaporeans have no alternative.
Singaporeans have the alternative of not owning a car - both public transport and taxis are highly available, cheap and very pleasant to use. If you see a car as merely a means of transport in exchange for economic value, it makes no sense to own one at current market prices (it's cheaper to take a cab every day, for example - even if you live near the airport and work in CBD, a 15km commute, that's $40/day or $80,000/10 years). Why do some Singaporeans take out 30 year mortgages for the right to drive an average sedan for 10 years?
What the COE taught me is the value of intangibles like status boost and the pleasure of driving for its own sake. This is more relevant to Tesla's target demographic than the considerations of the average second hand Toyota Corolla buyer (closer to where I would fit in, and why I'll never own a car in Singapore, no matter my net worth).
I think $100k cars are already limited to rich people.
You can be outside the 18k miles but if the problems began inside the first 18k miles, you qualify. I have personally had a car bought back a couple of months ago. After rejecting the manufacturers' initial offer of monetary compensation and sending a letter to the company on attorney letterhead, the mfr immediately folded and offered to buy it back for the full amount required by the CA lemon law.

Tesla is a public company, so this cost must make its way into an annual report, right?
2: Troll factor - people who just want to see the company fail.
3: Tesla's own professional paranoia. It's cheaper and easier to replace a faulty unit now to inspect it and determine how to make a future unit more resilient than it is to deal with bad press in the future.
Then you have some people who baby their cars, and then you have the people who drive cars professionally who are looking for ways they can break things. 76 is not a signal when the company is making 700 cars a week, it's well below the noise threshold.
So there's enough points to counter. The simple truth is, anyone who's trying to come to a conclusion on this car this early is stupid. The fact that this test was called "Long-Term" should tell you something about the industry.
From this poll you can't even say you have a sample size of 76 cars as you only have a sample of 76 cars whose drive units have broken.
A different survey on the same website includes zero [1], and is more appropriate to answering the question of "How likely is it that a Model S will have its drive unit replaced?"

Another case of "just because its possible doesn't mean you should". It will be fixed with 3 lines of code (to create a gear friendly torque curve) and a whole lot of PR to explain it.
Static friction is the same in equivalent spec'd ICEs, so if the Tesla is overtorquing, wouldn't they be able to back off on wattage for a few ms when starting out, and retain virtually the same accelerations?
Obviously, torque availability at 0 rpm with a flat curve is the notable difference, but remember that launch control in the BMW will also occur at peak power RPMs with a clutch or torque converter taking up the difference in road "RPMs", so it's not that dissimilar a comparison at least in regard to the strength of gearboxes, half-shafts, differentials, axles, CV joints, et cetera. (Consider too that the BMW has changeable gears, not a fixed ratio; the complexity should give Tesla a nod for transmission strength)
BMW 550i (base) vs Tesla Model S P85
Cost: $63,900 vs $87,070
Curb Weight: 4277 vs 4647 lbs
Peak Power: 445 vs 416
Peak Torque: 480 vs 443 lb-ft
0-60 mph: 4.5 vs 4.2 seconds
Top Speed: 130 mph for both
So I think my point stands; I suspect a software update in the Tesla could likely alleviate strain to the gearbox, without much tangible sacrifice in specs.I'm curious what "to the wheel" power looks like after the final differential ratio, but have to leave :)

That is why it should be inspected, to catch problems before they become serious.
What is magic about annual maintenance? In my gasoline car, I change the oil around every 7500 miles (when the car tells me) and rotate the tires at the same time. Total cost about $50 a year. Brakes when they need it for around $200, and when I need it four tires for a little under $1000. Throw in a yearly emissions and safety inspection for $37.
Most gasoline cars will have a 5/60, or 10/100 powertrain warranty. But even outside of warranty, I know I am not going to have to pay $15,000 to fix it. I'm also not stuck going to the manufacturer, price shopping is possible and I'm sure would save money over a dealership.
How would a gas car do with that kind of non-stop driving?
Or a 4-hour each way commute for a Mon-Fri work week. Or 3 hours each way for seven days a week at 110km. That'd be soul destroying.
I complain about my 6km (4 mile) commute which takes about 10-15 minutes. Cannot fathom driving hours daily to do work. Even with ridesharing or podcasts or whatever else, that strikes me as a huge waste of life time.
One thing I've noticed about many of my colleagues in California - when they get a new job, they don't move. Indeed, I've actually had colleagues who've changed the company they work at to reduce their commute, rather than just moving.
When moving you're not just leaving a home behind, but (often) a social environment. Once there's family, you have to coordinate the move with their job/school/etc situation as well.
Switching jobs is the option with the least friction in those scenarios.
I think the Prop13 issue explains why most home owners can no longer sell their homes.
We moved after my dad and my mom got jobs, but he basically got laid off due to a restructuring on his first day. Due to some complications with pension/benefits, it was very expensive for him to go somewhere else, so he ended up going back to his old job.
I did know a few people who had extreme driving conditions. Our neighbor was an RFD postal carrier who had to drive a personal vehicle for delivery. His mileage wasn't extreme, but he replaced his brake pads monthly.
It is actually more miles than you can get on one tank of gas in an Escort.
I owned one, decent car but it needs a lot of maintenance.
8x oil change
4x inspect brakes & rotate tires (tesla would need this, too)
2x inspect axle boots and axle shaft joints, inspect clutch operation, inspect steering and suspension (tesla, too)
and 1x (right at 30k):
inspect drive belts
inspect timing belt
replace automatic transmission fluid
replace brake fluid (tesla, too)
replace engine air filter
replace engine coolant (tesla, although different)
replace front/rear diff fluid
replace manual transmission fluid
what? Are you changing your oil every 3.5k miles?
edit: I thought you were replying to the guy that said he did 150k per year. Tons of people do 30k per year with basic maintenance.
A modern, reliable car is virtually good as new at 30,000 miles with routine maintenance. Doing it all in one year wouldn't change that.
