Did Tesla Skip a Crucial Quality Step on the Model 3 Home Stretch?

did tesla skip a crucial quality step on the model 3 home stretch

A report in Reuters Tuesday sheds light on the frenzied final weeks of Tesla’s all-out push to reach a production target of 5,000 Model 3s per week by the end of June.

Workers claim CEO Elon Musk became agitated whenever the company’s Fremont, California production lines slowed or stopped due to robot issues, employees were pulled off the Model S line to cover Model 3 workers’ breaks, and longer hours with little advance notice became the norm.

Ultimately, Tesla was able to boast of building 5,031 Model 3s in the last seven days of June. But another report raises the question of whether Tesla skipped an important step in the production process in order to reach its goal.

A source familiar with the goings-ons within Fremont told Business Insider that Tesla abruptly ended brake and roll testing of near-completed vehicles. The test was cancelled at 3 a.m. on Tuesday, June 26th, the source claims. Documents sent to the publication show the range of tests involved in this step — tests no longer listed as “critical.”

Brake and roll testing ensures that vehicles leaving the factory display even braking force at each wheel, proper wheel balance, coasting drag, and speed sensor calibration. It isn’t known why this step was cancelled when it was, or who ordered it.

“To be extremely clear, we drive *every* Model 3 on our test track to verify braking, torque, squeal and rattle. There are no exceptions,” said Tesla spokesperson Dave Arnold in a statement to Business Insider. Arnold wouldn’t comment further on the test, including the question of whether Musk ordered it removed.

The same source also questions whether Tesla’s Model 3 production figure is accurate. Tesla’s claim that it “factory gated” 5,000 vehicles could hide the possibility that an unknown number of vehicles were actually built a week prior, but were held back for rework. Once the work wrapped up, those vehicles could have been added to the final week’s factory gating tally. Arnold claims this is irrelevant.

In a message sent to the publication, Arnold said “a small number of cars are built during a week, but factory-gated the following week, just as a small number of cars built the prior week may not be factory-gated until the following week. Both of those points are true for this last week of production, just as it is true every week. We are reporting our production numbers the same way as we always have.”

Both reports again raise the question of whether Tesla can sustain this level of production without burning out employees and machines. The company says it expects to reach 6,000 Model 3s per week by the end of August.

Even if it does manage to build that many Model 3s, one worker told Reuters that a traffic jam going into the plant’s paint shop (where Model 3s had apparently been given priority), as well as the need to pull workers off the Model S line, resulted in Model S output falling 800 vehicles short.

    Slightly off topic, but when did Business Insider become a credible source for news?

    Did TTAC Skip Crucial Fact-Checking Step Before Regurgitating Unsubstantiated Blog Post? Maybe I'm just cranky today, but I'm losing patience with blogs that reblog other blogs that print rumors. If this is The Truth About Cars, maybe do some journalism and find out the truth. Were braking tests dropped and on whose order, and what is the consequence? Find out, then tell us. If your headline requires a question mark, you're not ready to publish. The Internet has way too many speculative hot takes already.

  • ToolGuy Meanwhile in Germany...
  • Donald More stuff to break god I love having a nanny in my truck... find a good tuner and you can remove most of the stupid stuff they add like this and auto park when the doors open stupid stuff like that
  • John Williams Sounds like a Burnout Special you can put together on any 5.0 F150. Whoever said this was Cars and Coffee bait is right on the money.
  • ToolGuy Question: F-150 FP700 (  Bronze or  Black) supercharger kit is legal in 50 states, while the  Mustang supercharger kit is banned in California -- why??
  • Scott "It may not be the ideal hauler to take the clan cross-country to Wally World considering range anxiety "Range Anxiety is a chosen term that conceals as much as it discloses. You don't care about range that much if you can recharge quickly and current BV's (battery vehicles) can't, no matter how good the chargers are. From what I've been reading it is likely that within 5 years there will be batteries in cars, most likely Tesla's, that can charge fast enough with no harm to the batteries to satisfy all of us with no need to increase range beyond a real world 300-ish miles.And that's when I buy one.
