One problem related to radiator has been reported for the 2007 Chevrolet Tahoe. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2007 Chevrolet Tahoe based on all problems reported for the 2007 Tahoe.
The vehicle has a faulty throttle body and throttle position sensor that cause the vehicle to go into "engine power reduced" mode which basically means the vehicle doesn't move. The engine is still running, but the vehicle is inoperable. This has happened to me dozens of times, in intersections, and I have to roll off the side of the road. Additionally, the intake gaskets leak allowing fluid into the engine. The dash cracked. We have also replaced the air ride shocks (ltz model), the connector will wear a hole in the shock. We have also replaced broken motor mounts and tie rod ends. Additionally, the vehicle was constantly running hot and we replaced the thermostat and radiator. The vehicle leaks oil and our mechanic said that it's the rear main seal that needs to be replaced.
