Workers employed by firms which deliver parts to Jaguar Land Rover sites including Halewood are to take industrial action in a row over pay and jobs.
Members of Unite will walk out for half an hour on August 28 and ban overtime at four firms.
The agencies supply staff who deliver parts to JLR plants in the West Midlands and Halewood.
A Unite spokesman said: "Negotiations are ongoing and Unite hopes to reach an agreed resolution.
"The union has a meeting with the employers this Thursday (August 22) where we will be continuing to push for a settlement which ends low pay and exploitation while delivering permanency for agency workers.
"Unite has given seven days' notice of industrial action to DHL and other agencies providing services to JLR plants. The law insists that the union must take industrial action within 28 days of a ballot.
"The union will therefore take minimum action to allow talks to continue while keeping our mandate for action alive so negotiations can continue."
Around 3,500 workers are involved in the dispute.
The employers where workers were balloted for industrial action are DHL, NAC, Staffline and Milestones.
The action will consist of a half hour stoppage at the start of the workers' shifts on August 28.
In addition, Unite members will ban overtime from August 28 to 0700 on August 29
Hundreds of Range Rover Evoques and Land Rover Freelanders are being recalled by the manufacturer.
Jaguar Land Rover, which makes the cars at its Merseyside factory in Halewood, says 1,400 of the cars need to come back to the plant for inspections.
About 800 Evoques may have a steering issue, while another 600 Evoques and Freelanders could have faulty brakes. There have been no reported accidents.
The problems affect 235 cars in the UK.
A JLR spokesman said: "Land Rover is voluntarily conducting a safety recall to inspect the power steering gear mounting fixings in certain Range Rover Evoque models and the brake callipers in certain Freelander and Evoque models.
"Customers with vehicles that are potentially affected by these issues will be contacted in the near future."
The Halewood plant had been celebrating one of its most successful years.
International demand for the Evoque had pushed production to go 24 hours-a-day for the first time. Hundreds of new staff have also been taken on.
JLR recently reported that sales of the Evoque were up by 39% in November, compared to the same month in 2011.
Car makers in the UK saw a spike in manufacturing last month, according to figures released today.
The Society of Motor Manufacturers and Traders say it was the busiest May since 2004.
UK factories, which include Vauxhall's Ellesmere Port plant in Cheshire and Jaguar Land Rover's base in Halewood on Merseyside, made 141,146 cars last month. That was a 42.2% hike, with year-to-date volumes up by 17.3%
