Tesla's Infinite Mile Warranty
I think this is them just getting ahead of some possible long-term drive-train issues.http://www.mercurynews.com/60-second-business-break/ci_26323...http://www.motortrend.com/roadtests/oneyear/alternative/1404...http://insideevs.com/real-imagined-tesla-model-s-drivetrain-...Recently Edmunds sold their long-term Tesla Model S; but before they did so the car had four (yes, four) drivetrains replaced by Tesla Motors.  Motor Trend’s long term car is working on its 2nd.This does not make us ask the question “is drivetrain failure a common occurence in the Model S?”Because it  is.If you check out the latest numbers on a Tesla Motors Club poll, you will find that 75 (supposed) Model S owners have had a least 1 drive unit replaced - 12 of which have had it replaced more than once.(Fair disclaimer: There is always a couple jokers messing with the results of an uncontrolled poll like this. As a point of reference, TMC likely has somewhere around 5% of Model S owners as members)To their credit, Tesla service has been doing a yeoman’s job taking care of its clients.  Despite the many failure occurrences we have yet to hear of Tesla giving a Model S owner a difficult time in solving the problem (ie-replacing the drive unit entirely).The problem for customers will arise however when Tesla’s 4 year/50,000 mile warranty on the unit expires; that is when repairs reportedly greater than $10,000 a pop really start to hurt.Tesla has got to both get ahead of this issue for the upcoming models and instill consumer confidence in the vehicles while they're fixing it.
