Problems With the Traction Control on a 2006 Yukonby Horacio Garcia
The 2006 GMC or Cadillac Yukon Denali has a recall, technical service bulletins (TSB) and safety reports about the stability control on the SUV. The stability control on the Yukon assists the driver in controlling the vehicle during skids or unstable steering conditions. The problems with the stability control in the Yukon prevents the operator from having this assistance.
Hub and Wheel Assembly
A recall on the 2006 Yukon is published by the manufacturer on a hub and wheel assembly problem which is affecting the stability control of the GMC. The internal retention bolt of the hub assembly on the Yukon loosens because of improper installation and torque specifications. This loosening of the retention bolt causes the hub and wheel assembly to separate from the Yukon creating a stability control problem. Once this hub problem develops, the stability control attempts to compensate for the steering problem and causes the Yukon to become difficult to steer. The hub and wheel assembly needs to be replaced in order to correct this stability control problem.
Electrical System TSB
A TSB is published on the 2006 Yukon because of an electrical system problem which affects the stability control of the GMC. The electrical system on the Yukon develops a intermittent control problem with the systems such as stability control and other fault messages. This intermittent electrical system problem causes the stability control to engage when it is unnecessary. Once the stability control attempts to correct steering difficulties when the Yukon operator is not experiencing steering difficulties, the Yukon becomes difficult to steer. This problem can create accident situations during normal driving conditions. Corrosion in the wiring harness and electrical components is being attributed to this electrical system problem and the Yukon owner must replace the electronic controls or have them cleaned by the dealership.
Tire Pressure Problems
Another TSB is published on the 2006 Yukon because the tire pressure regulating system may create a stability control problem. The tire pressure regulating system may fail and cause the monitoring system to engage the stability control when the tire pressure is correct. There may be over compensation of the steering control by the stability control because the tire pressure regulating system is informing the electronic monitoring system that the tire pressure is low or high on one or more tires. Once this incorrect information is sent to the Yukon's computer and the stability control attempts to correct the steering control of the SUV, the Yukon driver will find the GMC hard to steer. The tire pressure regulator must be replaced in order to correct this stability control problem.
