25: Chevrolet Traverse
The corporate cousin of the Enclave, the Traverse, has its fair share of expensive repairs that owners will have to tend to. This SUV experiences a lot of overheating issues as time goes on, and this only tends to get worse as the vehicle ages (via Autolist).
There are also electrical issues that tend to relate to the interior of the car. The navigation system is also problematic. You will spend a pretty penny to keep the first-generation Traverse models on the road.
