Toyota is recalling 1.7 million vehicles worldwide over potential fuel leakage problems.
Over 3,000 Lexus cars are being recalled in the UK and a total of 15,500 Avensis.
Toyota wasΒ hit by a series of recalls in 2010 that have battered its long held reputation for reliability and quality. Last year it was fined over its handling of recalls.
The Avensis 2.0-litre and 2.4-litre petrol engine models, produced between July 2000 and September 2008, have two potential concerns.
The first relates to the fuel pipe, where small cracks can potentially develop after a long period of time.
The second relates to potential insufficient tightening of the fuel pump check valve. In the worst case, said Toyota, this may cause fuel to leak.
The issue affecting certain Lexus IS 250 petrol engine models, produced between August 2007 and February 2009, is related to the fuel pressure sensor.
Due to possible insufficient tightening, the fuel pressure sensor could loosen and in very rare cases fuel could leak.
There have been no reports of accidents.
