Faulty connection of the inerting system’s gas pipes could impair the intended distribution of argon shielding gas to the points where there could be contact between the leaking refrigerant R1234yf and hot engine components in the event of an accident. This would reduce the cooling effect of the inerting gas, leading to an increased risk of fire.
The Mercedes-Benz GLC models affected by this recall were manufactured between 5 February 2016 and 3 November 2020.
