I have a 2019 Blazer RS since the end of April. This blazer has the 5 trans setting AWD, sport awd, hill, trailer and 2wd. it has 4,000 miles on the car and all of the sudden the service all wheel drive light comes on. This warning light came on when we were in 2wd. The blazer is at the dealership right now. Cannot expect them to last forever. Has anyone had this issue yet?
