New 2017 Tahoe purchased 3 weeks ago. 1000 miles on it. Been to service three times now for check engine lights and reduced power. Though not legally lemon classification yet, Seems like I got a lemon on my hands. Previously owned a Mitsubishi Outlander. 75k miles and not one issue. Salesman Jeff Moe was great. This is the reason I haven't bought American in 20 years.
