“There is an electronic problem that continues to trip the warning for the Air Ride suspension system to fail leaving the vehicle stuck at its current ride height or it drops eithee the front or rear suspension to the ground while simultaneously raising the front or rear to its highest setting. It also causes the vehicle speed to drop immediately to 56 mph. Issue has been scanned by several dealers to determine air leaks, pinched wires, failing compressor and all were found to be in normal operation. This is a huge safety concern as well as a huge financial concern for the consumer.”

There was no warning at all and this is the first time it happens. …”
