Tesla stopped a 'brake and roll' test as it pushed to hit Model 3 goals with further safety cover-ups

  • Tesla has decided to skip a "brake-and-roll" testing step in the manufacturing of its Model 3 vehicles.
  • Tesla says it tests the Model 3's brakes and alignment in other parts of the factory, so the tests were redundant.
  • Shares in the electric vehicle maker plunged by more than 6 percent on Tuesday in mid-day trading.

Tesla eliminated brake tests in final days of Model 3 production

Tesla eliminated brake tests in final days of Model 3 production  

As it pushed to hit its electric vehicle production targets for the quarter, Tesla decided to skip "brake-and-roll" testing for its Model 3 sedans in its Fremont factory.

The news was first reported by Business Insider.

The company managed to meet a self-imposed deadline to produce 5,000 Model 3 cars in a week after several quarters of missing its goals.

But Tesla's stock plunged by more than 7 percent on Tuesday. Like other auto makers, the company is facing tariffs that will take effect on Friday. And, yesterday CFRA downgraded the stock from hold to sell, saying the company's "burst" production rate for its Model 3s won't be sustainable.

Tesla characterizes the brake-and-roll tests it recently suspended as redundant. The company told CNBC:

“Every car we build goes through rigorous quality checks and must meet exacting specifications, including brake tests. To be extremely clear, we drive *every* Model 3 on our test track to verify braking, torque, squeal and rattle. There are no exceptions.”

It has not yet said whether or when the tests may be reinstated.

According to Tesla, workers at its Fremont, California factory also conduct alignment checks on the GA3 (or General Assembly 3) line using a system that was designed in-house.

All vehicles have their brakes and alignment tested on-site after they're fully assembled and before they leave the Fremont factory to go to a service or delivery center, the company confirmed.

Tesla has also changed other processes to speed up production. For instance, the New York Times reported, Tesla reduced the number of spot welds use in the Model 3's underbelly by 300, or about 6 percent.
