We purchased a new 2021 Chevrolet 2500 Disel on Dec. 2,2021. Driving it home the engine light came on . Took it back the next day and they had to replace the fan . Was given a loaner . They took a fan off another truck supposedly, well today the 19th of Dec. The light came back on . Will be taking it back to dealer Monday . We have purchased a lemon !! Only has 935 miles on it . Should not be like this ,especially a brand new truck .
