Any vehicle owner has been there. You drove through a rural area on a summer night and the front fascia of your vehicle is now peppered with little black specks, also known as mayflies. Well, General Motors is feeling this pain heavily with some of its most important new vehicles. 

GM has issued a bulletin to dealerships advising them to inspect 2021 Chevrolet Tahoe and GMC Yukon units for black specks in the paint and clean them accordingly. Apparently the vehicles are stored near a lake after assembly and this lake is a social hotspot for mayflies. 

In at least one instance a dealership has had to repaint the hood of a 2021 Tahoe due to the residue lest from the mayfly infestation. Though GM’s bulletin notes that pressure-washing and polishing should remove the mayfly problem in nearly all cases. 

According to an Automotive News report, only 100 impacted units made their way to dealership lots. There’s still 2,600 SUVs in Arlington that need inspected prior to shipping to dealerships, meaning inventory of GM’s latest and greatest SUVs are going to remain low until GM can finish their inspection. 

The Arlington plant also produces the Chevrolet Suburban, GMC Yukon XL and Cadillac Escalade. GM has not disclosed if these models have also been impacted by the mayfly situation. 

While a relatively minor problem for a new vehicle launch, it is worth mentioning this problem seems very on-brand with the rest of 2020.
