Production issues at Jaguar Land Rover's Halewood plant, caused by a targeted cyber hack earlier this week, will last until at least Tuesday, it has been reported.

Workers have been told not to return to work until 9 September, the Liverpool Echo reports. Production at the site is understood to have been halted since 1 September.

It follows a cyber attack in which hackers claimed to have exploited a flaw in the British car maker’s IT system.

A notice sent to Halewood workers on 4 September stated: "Friday September 5 and Monday September 8: the leadership team has agreed that production associates will be stood down and will have hours banked in line with the corridor agreement.

"All colleagues are required to attend work as normal on Tuesday September 9 unless informed otherwise.”

Autocar understands the Solihull plant, where the Range Rover and Range Rover Sport are built, is also affected. JLR wouldn’t comment on the claims.

In an effort to combat the hack, JLR said it began “shutting down our systems” on Tuesday and is now in the process of rebuilding them. JLR was unable to confirm a timescale for the fix.

The issues are also affecting dealers, who are unable to order parts, can't code parts they do have to cars, and are unable – in some instances – to complete customer handovers.

In addition, they are having to manually register vehicles. This involves phoning the DVLA in each instance.

Autocar first reported the issues affecting JLR on 1 September, when dealers couldn't register new cars on 'new plate day' , traditionally one of the year's busiest for registrations.

JLR's public-facing website appears to be fully operational, including the car configurator.

Who has claimed responsibility?

On 3 September, Scattered Spider – the group that hacked Marks & Spencer in May, causing seven weeks of disruption and costing £300 million in lost operating profit – claimed responsibility for the attack on JLR.

Along with fellow hacking group Shiny Hunters, it claims to have obtained customer data after exploiting a similar flaw in JLR’s IT system, The Telegraph reports.

The claim was made on a Telegram messenger group, where a user linked to the hackers posted a screenshot of what appeared to show JLR's internal system.

A member of the group told The Telegraph that a well-known flaw in SAP Netweaver - third-party software used by JLR - was exploited to access the data.

US cyber agency CISA warned about the flaw earlier this year. An update for the software was released, but whether JLR applied it is unknown.

It's also not known what data was taken or if a ransom demand has been made. 

JLR told Autocar in a statement on 3 September that “there is no evidence any customer data has been stolen”.

​According to The Telegraph, the hacking groups are believed to be made up of teenagers from English-speaking countries.

The Porsche 911 was name-checked as one of the models helping fuel Volkswagen Group’s growing order bank in western Europe at its recent half-year financial results.

A sports car now costing in excess of £100,000 even for a base rear-wheeldrive Carrera (just four years ago, it was a smidge over £80,000) may seem an odd model to call out for driving growth at the world’s second largest car maker, yet, 61 years after its introduction, the 911 is as crucial for Porsche as ever.

Almost one in six sold is still a 911, some 25,000 having found homes in the first half of 2025. That’s actually a small drop year-on-year but explained by a model changeover, and the order bank remains strong.

The 911 has outsold the combustion-engined Macan, Panamera, 718 Boxster/Cayman and Taycan, and only the Cayenne and electric Macan sit above it. In the UK, it’s only second to the Macan. Remarkable.

Necessary too, for the 911’s robustness is a rare bright spot for Porsche.

Oliver Blume, CEO of both the VW Group and Porsche (and you thought you were busy…) took questions on a pretty bleak present for Porsche ahead of its own results being published. There have been year-on-year declines in sales volumes, sales revenues, profi ts and operating margins, with the latter the scariest: Porsche’s margin is just 5.5%, down 65% year-on-year and akin to that of a moderately successful volume car maker. Given its price hike, you would expect the 911 to be doing plenty of heavy lifting within that overall margin too.

Blume, calm and measured, told me three things that are making the brand suffer: the collapse of the luxury market in China, import tariffs to the US and the slower than expected demand for EVs. The result has “put the business model of Porsche under pressure”.

Porsche has been hit more than most by tariffs in the US (all of its cars are imported to the US from Europe) and the Chinese market dynamic changes as “the US and China are by far the biggest markets for Porsche”.

In the case of China, Blume quoted a luxury market decline of 34% in 2024 and another 50% in the first half of this year. “Porsche lost a lot of volume,” he said – 28% so far in 2025, to be precise.

Porsche’s recovery plan includes investment in a major new model that extends beyond EVs and back towards combustion-engined cars in response to the EV slowdown. Alongside this is a huge cost saving programme that will save hundreds of millions of euros in costs and cut around 15% of its workforce by 2029.

Yet one thing won’t change: the 911. With such a strong order bank, expect the 911 to remain the shining light as Porsche looks to escape a turbulent period.
