Several current and former Tesla employees say the electric vehicle (EV) car manufacturer is building a high ratio of flawed parts and vehicles that need rework and repairs.
According to sources, Tesla has had to ship some flawed parts to remanufacturing facilities to avoid scrapping them, rather than fixing them in-line, however Tesla is denying the claim.
A current Tesla engineer told CNBC news that around 40 per cent of the parts made or received at its Fremont factory require rework. The need for reviews of parts coming off the line, and rework, has contributed to Model 3 delays, the engineer said.
To deal with a build-up of flawed parts and vehicles, Tesla has brought in teams of technicians and engineers from its service centres and remanufacturing lines to help with rework and repairs on site in Fremont, according to the sources.
Tesla flatly denies that its remanufacturing teams engage in rework. “Our remanufacturing team does not ‘rework’ cars,” a spokesperson said. The company said the employees might be conflating rework and remanufacturing. It also said every vehicle is subjected to rigorous quality control involving more than 500 inspections and tests.
CEO Elon Musk has been under serious pressure to increase production of the Model 3 sedan, Tesla’s first mass-market EV. More than 400,000 customers have reserved the EV, paying US$1,000 refundable fees to do so.
Originally Musk said that Tesla would be making around 20,000 Model 3s per month by December. The company then later downgraded those expectations – Tesla is currently making around 2,500 Model 3s per week.
Tesla has acknowledged problems with production of batteries, but said it is still on track to meet its target of 2,500 Model 3s per week by the end of March, and 5,000 Model 3s per week by the end of the second quarter.
