This car belonged to my brother until a few weeks ago. He had shops try to fix this issue. He is a multimillionaire and spared no expense trying to get the shaking and shuddering stopped as you brake. It was a car for one of his salesmen. The car has about 90,000 miles on it but it is not considered safe to drive as it it very scary when the brakes are applied. I do not know how the guy put up with it for all those miles. The problem has never been solved. The car is worthless because of this.

I notice that there are many references to this. What can be done to correct it. Another one of GM's under the rug issues I presume. We may have to change that with legal action.
