Volkswagen is conducting a recall for a few vehicles in the United States which may have been assembled without the bolts securing the front seat tracks.

There are 56 units of the 2021 Tiguan LWB affected by this safety recall, made between October 20 and 27, 2020, and only one Jetta, which was put together on October 21 last year, according to the National Highway Traffic Safety Administration (NHTSA).

The estimated defect rate is one percent, as some of them are missing the front seat track bolts. This allows the seats to move forwards and backwards without any restrictions, which would increase the risk of an injury in the event of a crash. Owners might also hear noises coming from the seats on bumpy roads.

In the ‘Description of the Cause’, the safety agency explains that the “Horizontal Displacement Movement bolts were removed in the re-work station, and the correct re-installment had not been verified before the next production step”.

VW became aware of the issue last October, during a test drive at the Mexico Test Track, when noise and vibration coming from the driver’s seat were detected. They started investigating the issue, and two months later, they discussed it in a Safety Committee meeting. The decision to announce a recall was decided on January 27.

As the bolts are not available in service centers yet, owners will have to wait a while until they will be contacted by the car manufacturer. The recall is expected to begin on April 2, with technicians inspecting the front seat tracks for missing bolts and installing them if necessary. All work will be carried out free of charge, but in the NHTSA report it is stated that VW will not offer a reimbursement plan.
