How do I know if my air suspension is bad?
Air suspension systems are a modern marvel in automotive technology, providing a smoother ride and improved handling. However, like any component in your vehicle, they can wear out over time. At Kevin's Autos, with years of experience in car maintenance and repair, we’ve seen our fair share of air suspension issues. In this article, we’ll guide you through the signs of a failing air suspension system and what you can do about it.
What Is an Air Suspension System?
An air suspension system replaces traditional coil springs with air springs, which are rubber and plastic bags inflated to a specific pressure to support the vehicle. These systems are often found in luxury vehicles and trucks, offering adjustable ride height and enhanced comfort. However, they are more complex than traditional suspensions, making it crucial to recognize when something is wrong.
Signs Your Air Suspension May Be Failing
Here are some common symptoms that indicate your air suspension system might be in trouble:
- Uneven Ride Height: If one side of your vehicle sits lower than the other, it could mean an air spring has failed or there’s a leak in the system.
- Excessive Bouncing: A properly functioning air suspension absorbs shocks effectively. If your ride feels unusually bouncy, it’s a sign the system isn’t working as it should.
- Warning Light on Dashboard: Many vehicles with air suspension systems have sensors that monitor their performance. If a warning light appears, it’s time to investigate.
- Hissing Sounds: A hissing noise while the vehicle is parked or in motion could indicate an air leak in the suspension system.
- Compressor Issues: If the air compressor runs constantly or fails to turn on, it could mean the compressor is overworked due to a leak or has failed entirely.
What Causes Air Suspension Problems?
Several factors can lead to air suspension issues, including:
- Wear and Tear: Over time, the rubber components in air springs can crack or degrade, leading to leaks.
- Corrosion: Moisture can cause metal components in the system to rust, affecting performance.
- Compressor Failure: The air compressor can wear out from overuse, especially if there’s a leak in the system.
- Electrical Issues: Faulty sensors or wiring can disrupt the system’s operation.
What Should You Do If You Suspect a Problem?
If you notice any of the symptoms above, it’s essential to address the issue promptly to avoid further damage. Here’s what you can do:
- Inspect for Visible Damage: Look for cracks, leaks, or other visible signs of wear on the air springs and hoses.
- Listen for Unusual Noises: Pay attention to any hissing sounds or unusual compressor activity.
- Consult a Professional: Air suspension systems are complex, and diagnosing the issue often requires specialized tools and expertise. At Kevin’s Autos, we’re equipped to handle air suspension repairs efficiently and affordably.

Frequently Asked Questions
What does blown suspension feel like?
If your car is bouncing significantly at the slightest dip in the road or rattling on seemingly smooth roads, your vehicle is likely in need of repair.
What are the symptoms of air suspension failure?
These signs can include unusual vehicle behavior, poor ride quality, noises, warning lights, changes in ride height, slow response, and increased fuel consumption. Other signs can include vibrations, a decrease in ride quality, or visible damage to the suspension components.
How do you diagnose suspension failure?
How can I tell if my car has suspension problems?
- Pulling to one side when driving.
- Bumpy rides are more common.
- One corner sits lower than others.
- Diving, rolling or squatting.
- Difficulty with steering.
- Oily shock absorbers.
How do I check if my suspension is bad?
Signs of suspension problems include: clunking sounds when hitting holes or speed bumps; the vehicle bouncing after hitting bumps or hole; the vehicle pulling to one side; the vehicle sitting unevenly to the ground, uneven tire wear; the vehicle leaning out when turning; hard or loose steering; and/or a rough ride ...
Is air suspension expensive to fix?
The average price of a complete air suspension kit can cost anywhere between about $2,000 up to $7,000, depending on your specific kit.
What happens if your air suspension goes out?
Driving a car with a broken or damaged suspension system is like walking with a broken leg. It will feel unbalanced and unstable, which can cause you to lose control of your car or worse.
How long does air suspension usually last?
80,000 to 100,000 miles
Air springs normally last 80,000 to 100,000 miles. Over this time, the rubber bladder dries out, and cracks appear around the bottom piston. Compressors usually wear out because of leaky air springs.
Can you drive with bad air suspension?
No. It is not recommended. A damaged or collapsed spring can cause sagging and noise and affect alignment angles. While you can still drive, the ride will be rough and the car will be difficult to control in an emergency.
How do you test air suspension?
An air suspension compressor test starts by listening for the part to turn on to see if it still works. If the air suspension compressor doesn't make noise, test the inoperative part with a digital multimeter to determine the exact issue and appropriate solution.
How do you know if you need new air suspension?
Increased Noise And Vibration
Your vehicle's air ride suspension needs repair once you notice an increase in the volume of noise and vibration emanating from the friction of the wheel against the body of your car.
