Is your Cadillac XTS suspension warning light on? Even if it’s not, you may still have noticeable problems with your air suspension.

If your XTS is sagging in the rear or leaning to one side, you are probably experiencing air suspension issues. This is also true if you have noticed a noisy compressor under the hood or a small “nose dive” when coming to a stop.

Whatever the issue, air suspension problems are worrisome. That’s mainly because they are expensive to fix and the repairs are endless once they begin.

Why does my Cadillac XTS have suspension problems?

Air suspensions are a marvel of modern automotive technology in some ways. They are complex systems of mechanical and electronic components that work together to create a smooth, balanced ride.

When they are working well, they offer great comfort and handling for the driver. Active suspensions in general have many advantages.

However, they also have an expiration date.

In order to function properly, your air suspension relies on a mechanical compressor, electronic and mechanical ride-height sensors, air bags, pneumatic air tubes and several small computers.

If that sounds like a lot, it’s because it is.

As with any system, any increase in complexity means an increase in the probability of failure at one point or another.

With these systems being interdependent, one component not working properly throws the entire system out of whack. Other components will overcompensate to try and right the situation. This will cause early failure of other components.

So air suspension problems in your Cadillac XTS aren’t a matter of if, but when.

Why are Cadillac XTS air suspensions so expensive to fix?



Knowing that the Cadillac XTS air suspension is so complicated, you can expect that it is very expensive to fix.

For starters, the components themselves are quite expensive. Each air spring will run you just shy of $200. That doesn’t sound like much at first.

But wait, knowing that soon after you replace the first air spring you’ll need to replace the other three, you’re already signing up for $800 worth of parts. Then you’ve got to pay someone to install them.

But say you decide it’s worth it to replace all of your air springs. Your ride height sensors and compressors are all moving parts and they will wear out eventually. You’re looking at several hundred to a thousand dollars’ worth of parts there.

You’ve also got a suspension control module and all the tubes and wires that connect everything to worry about.

And once again, you are working with a very complex system with a lot of little nuances. That means increased labor time.

All-in-all, there are a lot of reasons why these systems are so expensive to fix.
