Customers started complaining about grining noises coming from the rear under spirited cornering.
COnfused mechanics directly approached Anhultz with the issue after declaring nothing wrong with the respective vehicles.
In looks of maximum customer satisfaction and thus customer loyalty, they launched an investigation, thoroughly testing the Superkroon under the conditions as described by the customers.
They discovered that part of the rear floor structure may strike the pavement under hard cornering, for example when swerving to avoid collision with wildlife crossing the road.
While they determined the issue to be of no concern for stability or vehicle safety, they did alter the floor structure to include hard rubber skid blocks to avoid metal-to-pavement contact and thus elimiate the associated noise and/ or damage to vehicle or pavement.
A letter was subsequently sent to each existing Anhultz Superkroon owner, stating that they were advised, but not mandated to visit their local Anhultz repair centre to have the blocks installed at no charge to the customer (apart from having to drive to the shop).
The repair shops were tasked with installing the blocks and altering the service history leaflets to include replacement of those blocks (quoted at 15 minutes of additional work) together with every oil-change.
