2018 Chevrolet Tahoe Transmission and drivetrain Problems

“We just had to spend $1,000 to have the radiator replaced on our 2018 Chevrolet Tahoe because it was leaking which only has 32,050 miles on it. The Tahoe had a 3 year 36,000 mile bumper to bumper warranty, but we were two (2) days past the 3 year mark so they would not cover it. The Tahoe also has a 5 year 60,000 powertrain warranty, but the dealership said that the radiator is not considered to be part of the power train only the hoses going from the radiator to the engine were covered under the powertrain warranty. …”
