Re: Tahoe/Yukon Hybrid Problems: Brake Loss, Service Traction Control,Service Stabili
Dealers were not ready for many of the new systems in hybrids. Some still are not. The 08 has many more pressure sensors in the main brake module ( under the driver's seat ) under floor that later models don't have. If that system has been opened and or improperly adjusted, the system can and usually does act up. There are very fussy procedures for the bleeding of hydraulics and calibration of the sensors. If either had been done in the past, a re-do by an experienced dealer may be in order. Either way getting the technical line folks to help should minimize just Easter Egg hunting for the problem. Before swapping expensive parts, have more than a guess on your side.
