what i did is take your provision for warranty line and divide by delivered units. the provisioning changes as they expect more or less expenses, or as the reserve gets too high (low). i thought using the provision is better as it incorporates their expectations for the future vs. what they have already accrued.
you'll see the provision per vehicle stable for 4 quarters 17q2-18q1 and suddenly jump 18q2. do a little math assuming s/x provisioning was stable and you'll see the ~6% provision for each model 3.

Here's what Tesla said about their warranty expenses in the Q2 financial report:
"Warranty expense is recorded as a component of cost of revenues. Accrued warranty activity consisted of the following (in thousands):
For the three and six months ended June 30, 2018, warranty costs incurred for vehicles accounted for as operating leases or collateralized debt arrangements were $7.0 million and $12.8 million, respectively, and for the three and six months ended June 30, 2017, such costs were $7.4 million and $13.5 million, respectively."[TD2] 2018/Q2 [/TD2][TD2] 2017/Q2 [/TD2][TD2] 2018/H1 [/TD2][TD2] 2017/H1 [/TD2] [TD2] $465,866 [/TD2][TD2] $306,951 [/TD2][TD2] $401,790 [/TD2][TD2] $266,655[/TD2] [TD2] -$49,604 [/TD2][TD2] -$25,384 [/TD2][TD2] -$94,285 [/TD2][TD2] -$48,400[/TD2] [TD2] -$10,917 [/TD2][TD2] +$8,915 [/TD2][TD2] -$10,416 [/TD2][TD2] +$2,653[/TD2] [TD2] — [/TD2][TD2] — [/TD2][TD2] $37,139 [/TD2][TD2] —[/TD2] [TD2] $118,664 [/TD2][TD2] $52,797 [/TD2][TD2] $189,781 [/TD2][TD2] $122,371[/TD2] [TD2] $524,009 [/TD2][TD2] $343,279 [/TD2][TD2] $524,009 [/TD2][TD2] $343,279 [/TD2]

I believe the most important disclosure for our purposes here is the "Warranty costs incurred" line, which must include all warranty expenses, including labor, material and any directly billed services utilized, regardless of where they end up being assigned to in the end: automotive, services or SG&A.
Here's the history of "warranty costs incurred" for the last six quarters and the last 3 years looks like this, with a column for Model 3 deliveries:
[TD2] Warranty costs incurred [/TD2][TD2] Model S+X delivered [/TD2][TD2] Model 3 delivered [/TD2] [TD2] -$52,760 [/TD2][TD2] — [/TD2][TD2] — [/TD2] [TD2] -$79,147 [/TD2][TD2] — [/TD2][TD2] — [/TD2] [TD2] -$122,510 [/TD2][TD2] — [/TD2][TD2] — [/TD2] [TD2] — [/TD2][TD2] — [/TD2][TD2] — [/TD2] [TD2] -$23,016 [/TD2][TD2] 25,000 [/TD2][TD2] — [/TD2] [TD2] -$25,384 [/TD2][TD2] 22,000 [/TD2][TD2] — [/TD2] [TD2] -$39,481 [/TD2][TD2] 25,930 [/TD2][TD2] 220 [/TD2] [TD2] -$34,629 [/TD2][TD2] 28,320 [/TD2][TD2] 1,550 [/TD2] [TD2] -$44,681 [/TD2][TD2] 21,800 [/TD2][TD2] 8,180 [/TD2] [TD2] -$49,604 [/TD2][TD2] 22,300 [/TD2][TD2] 18,440 [/TD2]
Quarter 2015/all 2016/all 2017/all — 2017/Q1 2017/Q2 2017/Q3 2017/Q4 2018/Q1 2018/Q2
So firstly, while Model S/X deliveries were pretty flat over 2017 (except a bit of a glut early summer and then an end of year burst), there was a spike of warranty costs at Q3 - a big recall perhaps?
Secondly, beyond recalls, most warranty repairs happen in the first couple of months of a vehicle - a typical front-loaded distribution of component faults and assembly quality faults.
Based on that I think we can say that the Model S+X "baseline" warranty costs for 25k deliveries are around $1,000-$1,500/vehicle, or about 1.0-1.5% of ASP - with the real number probably closer to 1%.
We can also say that the about 9,950 early Model 3's, all delivered by March 31, probably already had most of their warranty work done by end of Q2 (June 30).
So if we conservatively estimate early Model 3 warranty overhead by including the Q2 increases in warranty costs but not include any Model 3 delivered in Q2 in the unit count, and take the very lowest of the Model S+X warranty baseline cost ($25m), then we get a per early Model 3 absolute maximum warranty cost of:
((39m+34m+44m+49m)-4*25m)/9,950 = $6,600 (11% of ASP)Note that this is close to the most pessimistic way to read these numbers and includes very early production batches that are not representative of Q3 production at all - and still it's not that bad for early production batches.
If we use the higher $35m estimate for the S+X warranty baseline (1.5% of ASP), then we get:
((39m+34m+44m+49m)-4*35m)/9,950 = $2,600 (4.3% of ASP)
Also, if we assume that half of the 18,440 Model 3's delivered in Q2 already had much of their warranty work done and expensed by end of Q2 (there was an end of Q1 peak that was delivered in early Q2), then the unit count increases from 9,950 to 19,170 and per unit warranty costs decrease further:
((39m+34m+44m+49m)-4*35m)/19,170 = $1,350 (2.2% of ASP)
Furthermore, if we consider that the first two quarters of Model 3 production went to employees, who wouldn't request 'paint speck' and other light defect warranty repairs, then we get the following for the about 19,170 Model 3's delivered in Q1 and the first half of Q2:
((44m+49m)-2*35m)/19,170 = $1,200 (2.0% of ASP)Note that the $1,200 estimate still includes Q1 vehicles with ~40% higher panel gap defects, which are pretty expensive to repair.
So if we only look at the Q2 increase in warranty costs of +$5m (note that Model S+X deliveries were flat at 22k in Q1 and Q2, there was no big recall, so their warranty costt baseline should be similar), and attribute that $5m cost increase to the about 9,950 Model 3's delivered in the second half of Q1 and first half of Q2 (about 10,000 vehicles), then we get this cost estimate for the 'newest' Model 3's:
5m/10,000 = $500Conclusion: the newer Model 3's we consider, the lower the warranty costs are expected to be, and the estimates seem to support this. I believe the current per unit incremental warranty costs for newly produced Model 3's, barring an expensive fleet-wide recalls, should be below $1,000 already in Q3 - maybe even lower than that. I.e. below 2% of ASP, closing in on the Model S/X levels.
This might sound surprising for a ramp-up that is only 12 months old and skipped the 'soft tooling' step, but it's not necessarily unexpected:
In any case your 6% estimate of Model 3 ASP looks conservative, so I wouldn't expect a negative surprise from that.
- The Model 3 was designed for mass manufacturing, the component count is much lower and the technologies are more automated, which reduces production quality noise once the lines are fine-tuned.
- The components are also much cheaper due to higher unit count sourcing, which reduces warranty material costs.
- Warranty labor costs might also be lower due to serviceability related re-design of certain aspects of the Model 3 that I assume they performed based on experience with the Model S/X.
- There's an incredible amount of scrutiny on early deliveries, due to the 'panel gap' and other Model 3 quality complaints publicity, there's a very detailed, very rigorous "Model 3 delivery check list" that other carmakers generally don't have to deal with. This too will fade out: later buyers won't complain as much about every paint speck or slight panel misalignment, plus the earlier scrutiny has put pressure on Tesla to improve quality to or beyond the quality levels of the competition. I.e. those who used early production quality complaints (which complaints were justified) as a FUD vehicle against Tesla (which is not justified) kind of did them a favor, by forcing improvements that improved Tesla's competitive position. The law of unintended consequences.
