Nissan has warned that it would "reconsider" its future in the UK if it left the European Union.
The head of Nissan Carlos Ghosn, told the BBC it would re-evaluate its position if the UK was to leave the EU.
Speaking at the launch of Nissan's new Qashqai model, he said: "If anything has to change we (would) need to reconsider our strategy and our investments for the future."
But he added that he considered such an exit unlikely.
Over time, the nut that holds on the steering wheel can become loose.
Drivers could start notice some wobbling of the wheel and if this is ignored there is the possibility that it could come completely off.
There have been a few incidents of steering wheels becoming loose, but there have been no accidents.
Nissan is recalling thousands of cars in the UK due to a potential steering wheel problem.
The recall affects 133,869 Nissan Micras made between December 2002 and May 2006 and is part of a worldwide recall of 841,000 Micras.
More than one million Honda vehicles are being recalled following concern over the airbags received from Japanese parts maker Takata Corp.
The firm confirmed 1.14 million cars will be called back globally.
Nissan has also been affected, with the company confirming 137,000 cars in Japan will be recalled.
David Cameron came face-to-face with an old Japanese tradition today, completing a ceremony started by former Prime Minister Margaret Thatcher in 1986. The 'Daruma Doll' is used to motivate people and help them complete goals.
When the goal is set, one eye is coloured in. When the goal is complete, the remaining eye is coloured in. Margaret Thatcher filled in the first eye during the official opening of Nissan's car plant in Tyne and Wear in 1986.
Today, David Cameron filled in the other eye to mark the production launch of Nissan's electric LEAF car.
Today's news is a strong endorsement of the quality of Britain's car industry which is creating jobs, taking on apprentices and contributing to building a stronger economy.
The auto sector is living up to being one of the great success stories of our industrial strategy and a testimony to government and private sector working together in close partnership.
This investment is excellent news for the North East and another vote of confidence for UK manufacturing.
The continued success of Nissan in the UK demonstrates the strength of the car industry here, and its importance as we rebalance and grow the economy.
This announcement shows how the car industry in partnership with the Government continues to win important long term investment projects in a tough competitive sector, helping the UK to get ahead in the global race.
- Production started at Nissan Sunderland Plant in September 1986.
- Total investment made and announced since then is over £3.5bn and total plant volume stands at more than 6.9 million units.
- 80 per cent of production is exported to 97 international markets.
- Its current model line-up is Qashqai, Qashqai+2, Juke and Note.
- Forthcoming production at the plant includes the 100% electric Nissan LEAF, the new Nissan Note and the next-generation Nissan Qashqai.
This milestone, our first premium product to be manufactured at Sunderland, reconfirms our commitment to UK manufacturing and the ongoing success of the plant which is moving up the value chain.
Just as important, the new Infiniti, which will be exported around the world, is being developed with help from our London design centre and our European Technical Centre.
Nissan's £250m investment will create a further 720 jobs in the UK supply chain, raising the new jobs total to 1,000.
The new model will be developed with help from Nissan's design centre in London and technical centre in Cranfield and then exported around the world, the firm said.
Around 280 of the new jobs will be in Sunderland, with the rest in other sites across the country.
The North East plant will build more than half a million cars this year, the first UK manufacturer to achieve this milestone.
