I have a 2005 Escalade currently with 37,000 and was told 2 months ago my car was out out warranty with a front end totally enclosed gear grinding problem. The latest commercial the CEO says, " we stand by out cars As Always 5 years or 100,000 miles". I have driven 8 highway trips of 800 miles and rarely use my vehicle during the week. This problem is unreal as to the quality of a $65,000 truck.
