    Dealership suggests new engine. Your take?

    My husband and I bought a used 2018 Chevy Tahoe with the 5.3 engine that everyone seems to hate a year ago. It now has 109,000 miles on it. In the spring we got a check engine light that suggested the oil sensor was the problem so we got a new one put in. A few months later, same thing, got...
