The recall effects Mazda 6 sedan and wagon models sold between 21 November 2013 and 2 October 2014. Mazda Australia has confirmed that 1298 vehicles will need to be returned to dealerships as a result of the issue.
According to the official recalls notice posted on the Australian Competition and Consumer Commission's product safety website recalls.gov.au, the problem stems from a programming error with the car's powertrain control module. According to the notice, the programming error "may fail to provide an adequate supply of electric power to the fuel pump following i-Stop operation".
"This may cause the fuel pump to stop operating, preventing the engine restarting or stalling after initial take off. If this occurs, the Malfunction Indicator Light (MIL) on the instrument panel will illuminate," the notice states.
The fault means the car may fail to restart or stall, and a traffic hazard may be the end result.
Mazda Australia senior manager of public relations Steve Maciver told CarAdvice, the recall only affects 2.5-litre Mazda 6 models, despite the same engine being fitted to the popular CX-5 SUV. Maciver said there have been no reported cases of the fault in Australia.
"We’ll be contacting owners of affected vehicles and asking them to present their car to their nearest Mazda dealer for a simple reprogram of the Powertrain Control Module (PCM)," Maciver said.
The latest Mazda 6 recall is the third electrics-related issue with the current-generation car. In 2013, more than 1500 Mazda 6s were recalled over a potential fire risk due to a faulty DC/DC converter, while earlier this year 9000 Mazda 6 models were recalled due to an electrical fault that could potentially see the car lose battery charge and stall.
