The Volkswagen plant in Pamplona in northern Spain has suspended production due to truck drivers protesting against high diesel prices.
"There is a shortage of supplier parts. The action is for one day but means that 1,438 vehicles cannot be produced," a VW spokesperson said on Monday.
The Polo, T-Cross and Taigo vehicle models are produced at the plant in the province of Navarra.
According to media reports, other industries in Spain have also been forced to reduce their activities due to a lack of supplies, with the supply of fresh food partially affected.
The protests, which started a week ago, are led by a grouping of goods transporters who represent only a small part of the Spanish transport sector.
Roads and distribution centres have been blocked.
The umbrella organization of Spanish trucking companies, CNCT, to which the protest platform does not belong, has spoken out against the protests.
However, the association warned ahead of a meeting with government representatives on Monday that this position would change if the state did not take "immediate measures" to alleviate the effects of high fuel prices on businesses.
