Now that would be embarrassing.
Having parts on Mercedes vehicle just falling off to be left lying in the road is not easy to imagine, but that's why Mercedes is recalling 4,765 Mercedes-Benz E450 4Matic Wagons built between the production dates of October 6, 2016, and January 9, 2019. According to Mercedes, the spoiler could detach from the vehicle completely at higher speeds, increasing the risk of a crash or injury to other road users. According to the recall notice, Mercedes owners should get some prior warning before the spoiler flutters away behind them and in the form of something they may not have heard before: A rattling noise.
If this sounds familiar, a report was filed on October 2018 and recall for 16 vehicles was issued in December the same year. Mercedes blamed the improperly mounted spoiler on "an employee temporarily assigned to the position." According to the recall document, "DAG (Daimler AG) continued to improve upon its production processes. In November 2018, DAG added an additional worker to the station."
The problem has persisted though, and according to the report: "It was determined that the production concern was not limited to the single worker. Based on this finding, investigations were performed to determine which vehicles could potentially be affected."
Mercedes actually expects a small number of the recalled vehicles will have the problem. The recall is expected to start in the US in early November 2019. The majority of the vehicles are in the US, but a little over 500 of the affected vehicle are in Canada. The fix is for Mercedes to check the mounting points on each vehicle, and if the spoiler is not mounted to specification then they will correct it. According to DAG, owners of E450 4MATIC Wagons built after January 9 this year can be assured that a change in production procedure at the plant has ensured the issue "can no longer occur."
