Tesla Employees Claim Delays Are Due To The Huge Number Of Faulty Parts

A group of current and former Tesla employees claim that the electric automaker is having trouble assembling its vehicles on time because a large portion of the parts received from suppliers are sub-standard.

CNBC claims that, according to one current Tesla engineer, roughly 40 per cent of the parts made or received at Tesla’s Fremont factory require rework. The employee also states that the need to review and rework parts is a factor in Model 3 delays.

What’s more, another current employee asserts that Tesla is struggling to reach production targets because of the defective parts. Teams of technicians and engineers from its remanufacturing lines and service centers have also been brought in to aid in the rework and repairs, staff claim.

Moreover, Tesla is allegedly sending flawed and damaged parts from Fremont to its remanufacturing facility in California.

In response, Tesla released a strongly-worded statement denying quality issues with its parts and vehicles:

“Every Model S or Model X on the assembly line must pass through hundreds of inspection and test points. Towards the end of the line, every vehicle is then subjected to an additional quality control process involving more than 500 other inspections and tests. The majority of issues identified at the end of line inspection are extremely minor, and are resolved in a matter of minutes.”

It is common procedure for large automakers to evaluate and repair used vehicle parts in remanufacturing facilities to make them as good as new. These parts are typically used by certified pre-owned vehicles or those being repaired. Unlike most, Tesla doesn’t outsource remanufacturing, but instead does it in-house.

        True that.

      Ha Ha! So true. Tesla fanboiz working overtime to justify why the employees are wrong (the wheels on the bus go round and…).

      • Matthew Daraei

        Haha, exactly.


    Tsk……tsk…….tsk. It would be easy to dismiss such claims but I mean we live in a world where your airbag could kill you, engines catch on fire, cars roll away unexpectedly and your steering wheel can snap off. I wouldn’t be surprised if this was true especially given all the things we have seen.

  • UGH! Another Tesla Story

  • If Tesla can’t improve the build quality soon, I wonder how they will stand against assault from Big Three Germany and Jaguar.

    • BlackPegasus

      For most Tesla owners, it’s not about energy consumption or fuel savings [as the majority of Tesla owners never bought a Toyota Prius nor any other EV on the market]. It’s about image and perception. Tesla will be unaffected by the EV offerings of other manufacturers.

      • nastinupe

        I disagree. The image of Tesla is about green and exclusivity. Once there are superior cars on the market from higher pedigree companies, Mercedes, Porsche, Audi, BMW, Jaguar, Land Rover they will return to their normally scheduled program. Tesla is very 2010’s. Once the 20’s get here things will be entirely different.

        • BlackPegasus

          “Exclusivity” is the driving factor behind my comment, so essentially we agree more than disagree.

      • Unfortunately yes, it’s like iPhone. They used to be innovative but not just a slightly better version of the last one, but people will still buy them nevertheless. Which is shame since I believe that only customer will can make company change.

      Well Jaguar LR doesn’t have a great reliability track record… So we’ll see how the i-Pace will do.

      • Adilos Nave

        Hasn’t their reliability improved substantially since being purchased by TATA? Sure, I’d never have considered a Jaguar 10 years ago but I think things are far different today. I hope the i-Pace does well because it blows the doors off the Model X. It’s a real car made by a true car manufacturer and not a bunch of coders sitting behind their laptop screens.

        • Sébastien

          Even Velar isn’t very reliable when it comes to electronics, so I really hope iPace starts being an exception

        • And that true manufacturer just forgot that these cars need recharging, otherwise it will take 5 hours to make a 3 hours trip. Why? Because Jaguar forgot about the infrastructure (that the “bunch of coders” already have, hence why Tesla is not making profits), and the gov/privately owned rapid chargers are only 50kW (that means the i-Pace will take 2 hours to recharge). While the plenty and well located Tesla chargers are 150kW. i-Pace is great for posing (very good looking car), the Model X actually works. That’s a major difference.

      • JLR product is not on the top of reliability mark but they aren’t in bottom either. LR products is definitely reliable and one factor is that a lot of conservative buyers is attracted to name like JLR and Big Three of Germany compared to start up from US.

    • LeStori

      Seems like supplier quality problems . The supply chain is always a weak link.Jjust look at Jaguar in the 1970s and 80s. Went from desireable in the 1960s to best buy 2 Jaguars. One to drive whilst the other was being repaired.

      • Well the workforce also play in part. Many of them are in strikes or perform their job badly during the British Leyland mess in 70s and 80s. It affect every single of the vehicles, sure bad suppliers also came in hand but another factor is workforce and lack of testing.

  • Six_Tymes

    But WHY are there so many faultily parts? No one knows WHY if this is true? Are suppliers trying to sabotage Tesla?

    • Adilos Nave

      That’s part of being a car manufacturer. Quality Control ends with them, not the suppliers. At the end of the day, it’s the car manufacturer that gets a check from the consumer so it’s on them to make sure the suppliers are giving them good parts. Tesla can blame the suppliers all they want but this is what REAL car manufacturers deal with. And somehow, they manage to make it work.

      • Six_Tymes

        you pointed out the obvious and not any information that I don’t already know, AND you missed the point.

        • Dr Strangefinger

          Woe woe woe… I’ve seen where you’ve missed the point 4, 5, even 6 Times in other articles. So, ease up a bit Sparky and stop pointing your finger at others before your own affairs are in order.

          Oh, and SELF-UPVOTE!

          • Six_Tymes

            never self up voted, and if it shows that way I have no idea how. you come in gangs here? take a chill yourself, no ones angry, except you maybe. why not read what I wrote, its easy to understand, I even capitalized so its easy for you both. oh wait, you wont read it, so ill type it again. WHY are suppliers giving them 40% rework parts, that’s an abnormally high rate. research it

          • Dr Strangefinger

            Spent most of the night going back and self upvoting my old comments. I know that you’d like that I did. I’m so exhausted…

            I’ll probably upvote this comment as well. You’re welcome.

      • LeStori

        Largely by chosing reliable suppliers and setting specifications that can be met. All part of the learning curve when you move into the mass production business. New for Tesla who are trying to move from a boutique to a mass producer without a historical supplier base.
        NB even large manufacturers occasionally get suppliers who are out of their depth. Either because of incompitence of supplier or supplier is trying to hide information from their suppliers because of a conflict of interest. Seen it happen first hand.

    • James Morgan

      It could be the labor force is red flagging things to disrupt production. I knew a mechanic for a major airline. He once gleefully explained to me how during labor negotiations they would red tag items they would have otherwise let pass (at least until the plane could be serviced overnight). Technically, they going strictly by the book. But by removing planes from service they created disruptions that pressured management.

    • LeStori

      Suppliers who cannot manufacture to desired tolerances and/or poorly set specifications. It would be unlikely for a supplier to sabotage the product deliberately unless they wanted to go out of bussiness. The word would get around.

      All part of the problem is becoming a mass producer.

  • TheBelltower

    Tesla is also having problems getting parts to repair existing owners’ cars. They are going to need to fix this quickly.

  • SteersUright

    Its so hard to launch an all-new model, even for the established players but they don’t get as much press as they are nowhere near as under-the-microscope as Tesla is with its Model 3. Every all-new MB, Audi, GM, or any car all have tons of teething problems their first model year. Alfa Giulia was nearly crucified, the C7 Vette was grenading engines, the e92 M3 was tearing through engine bearings, a simple GTi will likely see water or fuel pump issues, and on…
    If they can get this mostly sorted by year 2 they’ll be fine.

  • Axiom Ethos

    Rushing the car 2 years earlier to market than originally planned and this is what happens when you’re Tesla. Rushed supplier sourcing, rushed tooling by skipping the beta phase, over-promising and under-delivering. Not to mention people who need the ev credit the most waiting for the base model lose out over those who can afford the higher end one. Tesla is skating on thin ice and needs to make some big corrections before the competition shows up.

  • LeStori

    If the parts are out of specification the suppliers chosen are second rate companies. Alternatively the specifications set by Tesla are too lenient and the wide variation in tolerance results in the requirement for rework.

  • Jason Panamera

    There is a reason why big automotive companies are still big and still in the game. Years of iteration of techonology, experience and knowledge makes the difference. Technological startup can grow inconceivably fast if it’s based on software/services or smaller devices. If you want to produce a car where lot’s of parts are provided by subcontractors, you need big assembly lines and distribution networks then you face real problems of this industry. And don’t think that older companies are innovative because you don’t see innovations implemented immediately. In word “car” there is 4th hidden letter s, which means safety, realiable, tested solutions.
