Remind customers that cycling the ignition or starting the vehicle will bring the trim height back to normal levels.
Some owners of 2013-2019 Cadillac XTS vehicles may comment that their vehicle is sitting low after being parked for several days or more.
Technicians may complete normal diagnostics for Air Suspension air leaks or low/uneven trim height with no trouble found.
It’s important to note that under normal conditions, it is typical and acceptable for the air suspension system to drop slightly over time. Changes in air temperature can affect trim height as well. The trim height can be expected to drop as much as 2.6mm for every 10-degree Fahrenheit drop in ambient temperature.
If a customer states that their vehicle loses trim height when parked and unused for several days but achieves and maintains normal trim height when cycling the ignition and using the vehicle regularly, this should be considered normal operations and no repairs are necessary.
Remind customers that cycling the ignition or starting the vehicle will bring the trim height back to normal levels.
