Ever hear of spacer fabric? Want to know why you should care about it? Because the spacer fabric in your Escalade may stop your airbags from deploying.

GM said it discovered the problem when the instrument panel covers started wrinkling and blistering. Spacer fabric sounds silly but this is an important fix, get it done as soon as possible.
