Toyota is set to up its communications activity as it faces a recall of millions of cars.

The recall is in relation to faulty accelerator pedal mechanisms, which – according to Toyota – may stick in a partially depressed position when worn down. The vehicle-maker may recall up to two million cars across Europe and is also recalling in the US and China.

As the models and exact number of affected vehicles is still under investigation, the brand intends to hold back on above-the-line communications and use digital channels until the investigation is finalised.

The company’s shares have dropped 16% in a week.
