Common Cadillac XTS Air Suspension Problems and Their Potential Fix
As far as we have seen in NHTSA complaints and forums, Cadillac XTS owners define air suspension issues in this vehicle as the complete suspension failure. It’s normal indeed, as the air suspension system seems completely inactive.
However, the actual issues or the causes of such occurrences vary. So, before your mind becomes horrified hearing about a complete air suspension replacement, learn what are the common issues behind people’s complaints about the air suspension failure in Cadillac XTS.
Failing To Raise Or Low Ride Height
As we mentioned earlier, the Cadillac XTS has this fancy adaptive air ride suspension thingy that’s supposed to automatically adjust the ride height depending on how you’re driving. But here’s the thing, some people are saying it doesn’t work at all. No matter how hard they try, they just can’t raise or lower their car using this system.
There are a bunch of complaints about it on this NHTSA website. Especially from drivers who ride 2013–2017 models of Cadillacs XTSs. Now, Cadillac says maybe it’s because of too much weight in the car that the leveling system can’t raise the vehicle or obstacles underneath the vehicle prevent it from lowering the ride height.
But honestly? Owners aren’t buying it. They think something else is going on here. And you know what? It might be a problem with the Ride Height Position Sensor that’s attached to some part inside the wheel well.
To troubleshoot and resolve this problem, we recommend following a series of steps carefully.
- Firstly, ensure that there are no obstructions present underneath the vehicle that could impede the functioning of the ride height adjustment system.
- Additionally, verify that excessive weight is not being placed on any specific areas of the car, which could potentially affect its ability to adjust ride height smoothly.
- If these initial checks yield no tangible results, owners should then inspect and test for any faults or malfunctions in the Ride Height Position Sensor itself. This can be achieved by conducting a diagnostic scan using specialized equipment suitable for identifying sensor-related issues.
- In some cases, thorough cleaning of the sensor may also be required, as dust, dirt, or debris accumulation can impede its proper functioning.
- Next, reset the electronic systems by disconnecting and reconnecting the vehicle’s battery. This can often rectify minor glitches within the system. After reconnection, attempt to adjust the ride height once again to see if any improvement has been made.
- If these initial troubleshooting steps do not solve the issue, it might be necessary to bring your Cadillac to an authorized service center or mechanic specializing in Cadillac vehicles for a more comprehensive diagnosis.
Air Compressor Failure
Numerous Cadillac XTS owners have raised alarm about a potentially life-threatening issue, which stems from the failure of the air suspension system.
