Thousands more Zafiras are now thought to pose a fire-risk with latest action following two previous recalls of 235,000 cars.
Vauxhall is recalling a further 47,000 Zafira ‘B’ models over fears faulty heating systems could cause a fire.
The second-generation Zafira, which was built between 2005 and 2014, was originally recalled in 2015 over a similar issue.
Some 235,000 cars were called back in two separate actions, with Vauxhall originally considering only models with older air-conditioning systems to be affected.
The fault has previously caused 168 Zafiras to catch fire.
Now, the carmaker has identified that Zafira B models with electronic climate control systems may also pose a potential fire risk.
The fault relates to the system’s heater blower and regulator, and is similar to the problem afflicting Zafiras with air-conditioning.
In a statement, Vauxhall said: “Vauxhall Motors considers the safety of its customers very seriously.
“Through continual testing, we are launching a recall of some Vauxhall Zafira models to replace the heater blower motor and regulator.
“These are the second generation models – Zafira B – built between 2005 and 2014 that were fitted with electronic climate control (ECC).
“There are 47,000 such cars in the UK.
“In agreement with the DVSA, we will write to owners using the keeper address data from the DVLA (Driver and Vehicle Licensing Agency) advising them to contact a Vauxhall Retailer to arrange to have the work carried out free of charge.
“Letters will start to be sent out from the end of this week.”
Earlier this year the DVSA confirmed it was launching a criminal investigation against Vauxhall.
MPs previously slammed Vauxhall for attributing the fault to “improper and unauthorised repairs”.
The Transport Select Committee also said the manufacturer showed “reckless disregard for safety” by being too slow to react to the number of vehicles catching fire.
More than 230,000 Zafira model Bs were sold between 2005 and 2014 that were at risk of catching fire.
The first fire was reported in 2009, with a further 161 incidents reportedly taking place since.
