The car maker recalled 2767 Corsas running with a 1.4-litre turbocharged engine to address another fire-related issue earlier this year, but reports by The Sun suggested significantly more models could be affected by a more widely spread problem in the car’s heating and ventilation system.
The paper said all models built since 2006 could be involved. The Corsa is the UK’s second best selling car after the Ford Fiesta, so the claims would mean up to 1.1 million cars are affected, with a potential recall bill to fix the problem totalling around £200 million for the brand.
The wiring fault that has allegedly caused dozens of fires is caused by metal contacts that can corrode over time and get hot as the connection loosens. This heat causes surrounding plastic parts to catch fire.
