Air compressors and air suspension fail
When the strut fails or a leak is present, it can cause the air compressors to never shut off as they try to compensate for the leak which causes them to fail prematurely. A qualified technician, such as one from YourMechanic, will be able to inspect your suspension system and make a proper diagnosis on the issue.

Sometimes, it`ll even overwork in the event of a leak. Either way, this causes your car`s compressor to stop working. Or, sometimes, the factory-installed air compressor is faulty from the start. The end-result is a failed air suspension system.
While air compressors do not have a specific lifetime, most VIAIR compressors are going to carry a one-year warranty. Looking at reviews and first-hand accounts, most VIAIR compressors are going to last between 3-5 years depending on use and abuse.
In the event that the amount of refrigerant in the system is not perfect, it could create too much pressure or strain and lead to compressor failure. Too little refrigerant is most likely caused by an insufficient charge from the last technician, or from a refrigerant leak.
A defective suspension system can be poorly aligned, comprised of inadequate materials, or experience fluid leakage. Parts of a vehicle`s suspension that can be defective include the springs, dampers, struts, torsion bars, shock absorbers, bushings, and control arms.
A possible sign you need to replace your air compressor is that you find yourself with little to no air pressure coming from your AC unit. Low pressure may come from displaced belts, but a lack of air pressure might also come from damaged controls.
