Luxury electric vehicle maker Tesla said its deliveries rose 4.5% in the third quarter from the same time last year.
But the company said "production bottlenecks" had left the company behind its planned ramp-up for the new Model 3 mass-market sedan.
Tesla said it delivered 26,150 vehicles in the third quarter, including 14,065 Model S vehicles and 11,865 Model X cars, up 17.7% from the second quarter of this year.
The California-based company delivered just 220 Model 3 sedans and produced 260 during the quarter.
In July, it began production of the Model 3, which starts at $35,000 - half the starting price of the Model S.
Tesla had said in its second-quarter financial report that it expects "to achieve a rate of 5,000 Model 3 vehicles per week by the end of 2017."
The car maker also said it expects at some point in 2018 to further ramp to a rate of "10,000 Model 3 vehicles per week," and an annual production rate in excess of 500,000 vehicles.
"It is important to emphasize that there are no fundamental issues with the Model 3 production or supply chain," Tesla said in a statement.
"We understand what needs to be fixed and we are confident of addressing the manufacturing bottleneck issues in the near term."
Tesla said it was on track to deliver around 100,000 S and X models this year.
