On affected vehicles it has been determined that drivers airbags with potentially faulty gas generator housing material may have been installed in vehicles of model series 156 176 246 205 238 & 253. If the material of the gas generator housing fails during airbag deployment in the event of a crash the airbag system would possibly no longer have a restraint effect. In addition separating parts could enter the passenger compartment. This could lead to an increased risk of injury.

Fix: On affected vehicles replace the driver�s airbag

Recalled models: GLA · 421 vehicles

The steering column clock spring may break. This will cause warning messages to illuminate in the instrument cluster but in extreme instances it may cause the driver's airbag to deploy.

Fix: Affected vehicles will be recalled to establish sufficient grounding of the steering components

Recalled models: GLA · 78,608 vehicles

It has been determined that the steering airbag electrical components are insufficiently grounded. Failure of the steering column module clock spring could result in an inadvertent deployment of the driver airbag which may cause risk of injury to the driver and an increased risk of a potential collision.

Fix: On affected vehicles the manufacturer will fit a contact bridge to the outer race of the steering column top bearing which will provide correct grounding.

Recalled models: GLA · 74,329 vehicles

The steering column clock spring may break. This will cause warning messages to illuminate in the instrument cluster but in extreme instances it may cause the driver's airbag to deploy.

Fix: Affected vehicles will be recalled to establish sufficient grounding of the steering components.

The connection fitting of the vacuum line to the brake booster is not to specification and my not be durable. If the connection fails the brake booster will no longer be supplied with vacuum. After a few brake applications the driver will have to apply additional pressure to the brake pedal to gain the appropriate braking effect.

Fix: Recall the vehicles that are likely to be affected and replace the vacuum line on the brake booster with a quality assured component.

Where the car incurs severe engine damage resulting in the engine failing to turn over (engine seizure) and if the driver repeatedly attempts to start the engine despite the engine not cranking the very high electrical current could lead to overheating of the starting current limiter and the potential for a fire.

Fix: Recall the vehicles that are likely to be affected and install an additional fuse in the electrical line to the starter.

A potentially faulty weld between the plate carrier and the hub of a clutch could be faulty/cracked and could fail. This can cause limp-home mode to be adopted or all drive to be lost. As a result the risk of a collision is heightened.

Fix: Recall the vehicles that are likely to be affected and replace the dual clutch of the transmission.

Recalled models: GLA · 38 vehicles

The high pressure fuel lines have not been manufactured to the correct specification which over time can lead to crack formation and fuel leaking. Fuel escaping in the presence of an ignition source could lead to fire.

Fix: Recall the vehicles that are likely to be affected and replace the high pressure fuel lines.

On certain petrol engines the camshafts may not have been correctly manufactured. They may fail causing engine damage and the engine to stall

Fix: On affected vehicles replace camshafts.

Recalled models: GLA · 4 vehicles

The camshaft could break and damage the engine due to it not being manufactured to the correct specification. If the condition occurs it will lead to a sudden loss of drive thereby increasing the risk of a collision.

Fix: Recall the vehicles that are likely to be affected and replace the intake camshaft.

Recalled models: GLA · 14 vehicles

The camshaft could break and damage the engine due to it not being manufactured to the correct specification. If the condition occurs it will lead to a sudden loss of drive thereby increasing the risk of a collision.

Certain fuses in the passenger's footwell may not have been fitted correctly. This may adversely affect the instrument cluster windscreen wipers and the passenger seat occupancy recognition system. In certain conditions this may cause the passenger's air bag not to deploy in an accident.

Fix: On affected vehicles check fuses and if necessary replace fuse box.

Recalled models: GLA · 1,028 vehicles

On certain diesel engines the 'O' ring may not have been produced to the correct specification. This may allow oil to leak and contaminate the environment. If excessive oil is lost engine damage may occur.

Fix: On affected vehicles replace the chain tensioner sealing ring.
