Tesla Stops Critical Brake and Roll Test to Meet Production Goals

Tesla likes to cut corners. Following news it eliminated 300 welds, comes news it stopped a brake and roll test.

There are several Tesla stories today, none of them any good.

Brake and Roll

Elon Musk ordered Tesla engineers to stop doing a critical brake and roll test on Model 3s cars.

Tesla CEO Elon Musk ordered his employees to stop putting nearly finished Model 3s through a critical test before leaving the company's factory in Fremont, California, according to an internal document viewed by Business Insider.

Ron Harbour, a consultant at Oliver Wyman who founded and writes "The Harbour Report," a worldwide guide to manufacturing, told Business Insider that after everything is installed in a car during the manufacturing process, a manufacturer would have to be very lucky for everything on a car to be in alignment.

"If you just abandon [the test], you could potentially have a lot of quality issues with your customers," he said. "Every plant does that ... It's part of finishing the build of the car."

Harbour told Business Insider he was unaware of any test that could adequately replace the brake-and-roll test on a manufacturing line.

Reservations and Deliveries Decline

  • Goldman Sachs is not impressed with Tesla's production announcement and reiterates its sell rating for the company's shares, noting net Model 3 reservations declined to 420,000 from 455,000 last year.
  • Tesla said Monday it reached its one-week production goal of 5,000 Model 3 cars for the last week of the June quarter. But the company fell short on its second-quarter deliveries by posting 40,740 vehicles delivered versus the Wall Street consensus expectation of approximately 51,000.

Shouting Elon Musk Changes Rules on the Fly

A tense and short-tempered Chief Executive Elon Musk barked at engineers on the Fremont, California assembly line. Tesla pulled workers from other departments to keep pumping out the Model 3 electric sedans, disrupting production of the Model S and X lines. And weekend shifts were mandatory.

Leading up to Sunday morning's production milestone, Musk paced the Model 3 line, snapping at his engineers when the around-the-clock production slowed or stopped due to problems with robots, one worker said. Tesla built a new line in just two weeks in a huge tent outside the main factory, an unprecedented move in an industry that takes years to plan out its assembly lines, and said the tented production area accounted for 20 percent of the Model 3s produced last week.

"They were borrowing people from our line all day to cover their (Model 3) breaks so the line would continue to move," said a Model S worker on Sunday.

Because of the focus on the Model 3, the S line is about 800 cars behind, the worker said.

"They've been throwing Model 3s ahead of the S to get painted to try to assure that they make their goal of 5,000," the worker said. "The paint department can't handle the volume."

"He (Musk) is gonna go through an awful lot of people because people are gonna start getting hurt left and right," by the fast-moving assembly line, a worker said.

Crap Quality

The quality of these rushed vehicles is guaranteed to be crap, just to make a self-imposed production number.

Mike "Mish" Shedlock

The short directed media campaign against Tesla is well clarified by the following description (

Predatory short sellers target financial/insurance companies, because they depend on capital markets. Because Tesla is investing so much cash in future prospects — more than it can replenish from sales of Models S and X — it has become like a financial company, and is vulnerable to short sellers and market sentiment (and market sentiment caused by short sellers). In Jesse’s view, the greatest threat to Tesla is not the legacy automakers or delays in Model 3 production. “It is the massive capital betting against him steered by bad actors with malicious intent and an incriminating history.”<<

Mish, how long is wait for you to retract the debunked claim that Tesla does not test Model 3 brakes? Don't want your readers mislead do we?

Predatory short sellers? What a F'ng joke.
