Several current and former Tesla employees say that this company is facing difficulties in ensuring compliance with the production process, and the main reason for such inconveniences is the non-compliant parts of the suppliers.
As CNBC writes, based on currently available Tesla engineers' information, about 40% all parts made or received from Freemont at Tesla's factory must be redone. An unidentified employee further assured that the need to pay extra attention to these parts is a major cause for Model 3 delays, Carscoops writes.
Moreover, another currently employed by Tesla has ensured that his workplace was not able to achieve the production targets due to defective parts. According to him, technical and engineering teams are called upon to help repair and repair the wrong parts. It is also reported that Tesla sends inappropriate and damaged parts to a refinery in the state of Fremont, California, USA.
For its part, the official Tesla representatives have released a particularly secure statement denying the trouble of the quality of the vehicles and their parts.
"Each Model S or Model X in the assembly line must go through hundreds of inspections and tests. The vehicles at the end of the assembly line are waiting for an additional quality control process, covering more than 500 other inspections and tests. Most problems at the end of the production line are very insignificant and resolved in just a few minutes, "the report said.
It is common for car manufacturers to evaluate and repair used vehicle parts in dedicated factories to make them worse than new ones. These parts end up in used or repaired cars. Unlike most of the major car manufacturers, Tesla has not transferred these parts to repair and repairs to other companies and does so independently.
