The shutdown follows a cyberattack on 31 August 2025 that has crippled JLR's IT systems and brought production to a halt. The incident, widely believed to be a ransomware assault, has disrupted operations not only in the UK but also at facilities in China, Slovakia, Brazil and India. Losses are estimated at 50 million pounds ($68 million) a week.

JLR, Britain's largest carmaker, operates three plants in the UK that together produce about 1,000 vehicles a day. With output stalled, reports said many of its 33,000 employees have been told to stay at home.

The ripple effects have also hit the supply chain, with nearly 200,000 jobs at risk across hundreds of supplier firms, according to media reports.

Tata Motors, part of the Tata Group, is a global automobile manufacturer of cars, utility vehicles, pickups, trucks, and buses.

Tata Motors reported a 62.7% decline in consolidated net profit to ₹ 3,924 crore in Q1 FY26 compared with ₹ 10,514 crore in Q1 FY25. Revenue from operations fell 2.5% YoY to ₹ 1,03,792 crore in Q1 FY26, with performance impacted by volume decline in all businesses and a drop in profitability primarily at JLR.
