Volkswagen has decided that a defect relating to vehicle safety exists in certain 2017-2019 Audi Q7 and 2019 Audi Q8 vehicles.
According to the defect report, as the result of a manual rework process, the bolt connecting the steering shaft to the steering gear may not have been properly torqued. The bolt could loosen over time, causing the connection between the steering shaft and steering gear to loosen and detach. If this happens, the driver could experience limited steering and possibly complete loss of steering control. If the condition is present in a vehicle, the driver may notice higher than normal play in the steering wheel.
Those receiving notices will be asked to return to their Audi dealers to have the st5eering shaft bolt inspected and replaced as necessary. Volkswagen's number for this recall is 36A1 and the NHTSA campaign number is 20V-149.
Volkswagen will also be recalling certain 2019-2020 Audi A6 vehicles equipped with mild-hybrid technology and 2.0 TFSI engines.
According to the defect report, the coating on the inverter inside the belt starter generator could develop cracks and allow moisture into the inverter. The moisture could short circuit the starter generator and could result in smoldering and a potential fire.
Owners will be asked to return to their dealership to have the starter generator replaced. Volkswagen's number for this recall is 27H2 and the NHTSA campaign number is 20V-153.
