I have a 2011 Cadillac Escalade ESV Premium. When I bought it, the Service Suspension System error was on the dash display. I also learned that you cannot go over 80mph with that error code. It has some type of safety feature to limit it. I replaced the suspension system air compressor, which corrected the Service Suspension System error, but the vehicle still limits only to 80mph. There are currently no error codes or dash messages. How do I get past this 80mph limitation? You also cannot set the cruise control over 75 as part of the safety feature. I would really like to get that corrected. Any help is appreciated.
