Tesla said it will delay the release of its Autopilots software update on Tuesday, two weeks ahead of the planned release.
The update, scheduled for Thursday, is expected to introduce a new mode for the autopilot that is intended to increase safety and reduce accidents in its first public test.
The delay is a blow to Tesla, which is expected on Wednesday to launch its first commercial car in the United States, a Model S that will be sold at dealerships nationwide.
Tesla announced its plans to release the software update to the public on Thursday.
It is the first of two major software updates that Tesla is expected next week, including one for its Autosteer software that is designed to make driving safer.
The Model S is Tesla’s most expensive electric vehicle and its popularity is expected be a key selling point in the Model 3, which will have a range of up to 300 miles.
The company’s first major software update, the autopilots update, was expected to release on Tuesday.
The software update will provide “enhanced and safer safety features” that allow drivers to take over when an autopilot system detects a car in motion, Tesla said in a blog post.
In addition to the safety feature, the new mode will “help to reduce accidents,” according to the post.
Tesla said in an interview with The Wall Street Journal that it would not be ready to release a full version of the software until late May or early June.
The Palo Alto, California-based automaker had said it expects to begin selling the Model S on the United Kingdom’s Autobahn starting in June.
