Audi’s first electric SUV will arrive in the showrooms four weeks late, pertaining to an unprecedented software issue, spokesman of the brand told Automotive News on Sunday.

The automaker justified the delay with new regulatory clearance for the piece of software that was modified during the development process.

Audi has introduced the fully-electric mid-size SUV last month in San Fransisco and raised the curtain for a new electrified act in its line-up. The new SUV was brought in by the German giant to put up a tough competition and lock horns with California based Tesla, who has been garnering attention in the EV segment since its inception in 2003.

Reports suggest that the news was first reported by German newspaper Bild am Sonntag which cited sources close to the company. Adding to this, the report also stated that the delivery of the new SUV could be delayed by several months.

Apart from that, Audi is also reportedly locked in price negotiations with South Korean battery supplier LG Chem which has demanded a price of 10 per cent due to high demand. LG Chem is responsible to supply electric vehicle batteries for Audi, its parent company Volkswagen as well as Daimler.

Earlier this month, Audi announced that it had ramped up the production of e-Tron at its Belgium plant by the end of this year. Managing Director of Audi Brussels, Patrick Danau stated that retooling the plant for the production of EVs was initially a challenging task. As it was first used for the manufacture of the company’s small hatchback A1 which only featured a combustion engine.
