Inesperado problema con el chasisde aluminioPara tratar de mantener el peso lo más contenido posible, Tesla ha optado por el aluminiopara fabricar el cuerpo del Model S . Una opción que permite que incluso montando unabatería de 85 kWh, la cifra en la báscula no penalice demasiado sus prestaciones.

Pero este bajo peso tiene un costo en forma de reparaciones. Son muchos los usuarios queestán descubriendo que cualquier paso por el taller para reparar un pequeño daño en lachapa del coche supone una factura de proporciones astronómicas.

Por ejemplo reparar una simple abolladura, que en un Mercedes sale por unos 1.600 euros,puede llegar a los 6.000 euros en un Model S . En caso de que el choque haya sido másimportante, tanto como para por ejemplo dañar ligeramente el frontal, la factura puede subirhasta nada menos que los 39.000 euros.

También hay que tener en cuenta que la reparación del cuerpo de aluminio requiere unamaquinaria y una mano de obra especializada . Para lograr un equipamiento homologadopor Tesla para este modelo, el taller debe afrontar una inversión de unos 86.000 euros . Unacifra que dada la pequeña cantidad de unidades en el mercado, hace que muchos usuariosno tengan acceso a una de estas instalaciones en su zona de residencia.

Los componentes tampoco son precisamente económicos. Un simple remache puede costarmás de 20 euros y un tubo de sellado para las juntas cuesta 86 euros, mano de obra aparte.Tesla incluso cobra hasta 130 euros por conceptos tan extraños como “asegurarse de que labatería permanece cargada durante la reparación”.

Esto significa que si dejamos aparcado el coche en la calle, y tenemos la mala suerte de queaparezca uno de los muchos energúmenos que disfrutan dañando coches estacionados, lafactura puede llegar a ser realmente escalofriant e incluso si lo comparamos con otroscoches de su segmento.

Tesla Model S Aluminum Body: WhyRepair Costs Are HigherBy: David Noland

As more and more Tesla Model S electric sport sedans hit the road—50,000-plus at lastcount—some of their drivers are naturally starting to have accidents.They are bumping into other cars, colliding with deer, scraping telephone poles, andbacking up into poles and trees.Their cars are suffering all the other dents, scratches, and dings that are an almost inevitablepart of a car's life.Fortunately, I have done none of those things in my 85-kilowatt-hour 2013 Tesla Model S.But I have to admit I’m starting to dread the day it happens.

NHTSA Tesla Model S crash test (Image: crashnet1 Youtube screen grab)The reason: a growing stream of owner reports of downright shocking Tesla repair bills andestimates for scratches, dents, and minor collisions.“Cost of repair crazy high” is how one Model S owner puts it in a thread on the TeslaMotor Club online owners forum.He describes a minor front-end collision, from which he was able to drive away, that costhim $20,327 to repair.Visible damage was limited to the front left fender, lights, and the corner of the hood. Butthe bill listed 92 hours of labor and almost $8,000 in parts, including a single self-piercingrivet billed at $35.

Other owners report a litany of outlandish repair costs or estimates. Among them:• A $10,000 estimate to repair a “minor but long” scratch• A $45,000 estimate for “minor front-end damage"• A $7,000 estimate for repair of a small dent and scratch that required no replacement of

parts• A $30,000 estimate for “minor fender and door damage"• An $11,000 estimate for a minor scrape on the rear panel, including a $155 charge to

“ensure battery remains charged” during the repair.

Based on these reports, and many other similar ones, it appears that a small child with abaseball bat could total a $100,000 Model S in about 30 seconds with a few well-placedwhacks.

Aluminum is tricky

There are a number of legitimate reasons that a Tesla Model S is more expensive to repairthan a standard car.First of all, the structure and body panels are made almost entirely of aluminum.Although it has many advantages over steel—lighter weight, better absorption of crashenergy, better corrosion resistance—aluminum is more difficult to work with than steel.“Aluminum has no memory,” explains Larry Peotter of Peotter’s Auto Body, a Tesla-authorized shop in Summit, New Jersey.

“Unlike steel, you can’t pull the frame or structural parts back into place. And it’s muchharder to repair a dent.""You try and work it, like a steel car, and it ends up losing strength," he explained. "It popsin and out like a soda can.”Aluminum structure and body panels make far greater use of rivets and bonding agents,which are time-consuming and expensive ($100 per tube for the sealant recommended byTesla).Factory training Like other high-end aluminum car manufacturers—Audi, Jaguar, and Range Rover amongthem—Tesla requires substantial factory training and specialized equipment for itsauthorized body shops.Peotter says he was required to buy about $100,000 in additional equipment and tools tobecome a Tesla-authorized shop—in addition to equipment he already had in the shop towork on aluminum Jaguars.He had to buy a special cradle to drop out the half-ton Tesla battery, for instance, in casestructural repairs required its removal.The Tesla factory training class lasts fully three weeks; according to Peotter, it is more in-depth and more intensive than Jaguar’s. It’s also more expensive for the shop.As a result of these higher training and equipment costs, Peotter’s shop rate for Teslas ishigher than its Jaguar aluminum rates--and nearly double the rate of a standard car. (Peotterwon’t say exactly what the rates are.)
