EU Safety GateThe electrical connector of the transmission wiring harness may not have been correctly processed.This can lead to water entering the connector, which could cause short circuit and can create a thermal overload of the connector when the vehicle is parked, causing the risk of fire.
Measures: Type of economic operator taking notified measure(s): Manufacturer; Category of measure(s): Recall of the product from end users; Date of entry into force: Unknown
EU Safety GateThe 48V ground cable bolt in the engine compartment may be incorrectly secured.This could increase electrical transition resistance at the point of connection. As a result, the high electrical currents that can flow through this connection could increase the temperature, increasing the risk of fire. Furthermore, the 48V electrical power supply failure may increase exhaust emissions. This could have a negative impact on the environment.
Measures: Type of economic operator taking notified measure(s): Manufacturer; Category of measure(s): Recall of the product from end users; Date of entry into force: Unknown
EU Safety GateThe seal for the special plug-in contact of the gearbox designed to protect against contact with moisture and splashing water is…The seal for the special plug-in contact of the gearbox designed to protect against contact with moisture and splashing water is improperly installed. Thus splashed water can enter the socket contact when driving in wet conditions and can lead to a short circuit, increasing the risk of a fire.
Measures: Type of economic operator taking notified measure(s): Manufacturer; Category of measure(s): Recall of the product from end users; Date of entry into force: Unknown
EU Safety GateThe length of the wiring harness of the front wheel speed sensors might be inadequate.As a result, in certain driving manoeuvres such as full steering wheel angle or full compression/rebound of the suspension, damage to the wiring harness due to tensile load might occur. This could lead to impairment of vehicle's dynamics control systems increasing the risk of an accident.
Measures: Type of economic operator taking notified measure(s): Manufacturer; Category of measure(s): Recall of the product from end users; Date of entry into force: Unknown
EU Safety GateA trapped particle may damage the sealing between the fuel rail and fuel injector, which could cause fuel to leak into the engine…A trapped particle may damage the sealing between the fuel rail and fuel injector, which could cause fuel to leak into the engine compartment. Consequently, leaking fuel may come into contact with hot parts of the engine, increasing the risk of fire.
Measures: Type of economic operator taking notified measure(s): Manufacturer; Category of measure(s): Recall of the product from end users; Date of entry into force: Unknown
EU Safety GateThe electrical connector of the side-impact sensors might not be correctly latched and could become detached.This would lead to delayed activation of the restraint systems in the event of a side impact, reducing their restraining effect and increasing the risk of injury to the vehicle occupants.
Measures: Type of economic operator taking notified measure(s): Manufacturer; Category of measure(s): Recall of the product from end users; Date of entry into force: Unknown
EU Safety GateDue to a defective screw connection, the starter motor positive cable may become damaged by the relative movements of the starter.Consequently, the cable could come into contact with the housing of the starter and cause a short circuit, which could lead to an engine stall and increased risk of fire.
