Tesla Air Suspension Repair Costs: Why the Same Symptom Bills $425 or $5,612

“What is the damage going to be (cost) when it’s time to replace them?”

That question, or some version of it, shows up every few weeks in the Model X forums, usually from someone who has just noticed one corner sitting lower in the driveway. The answers they get back range from a few hundred dollars to five figures, which is not much help.

Both answers are true. That is the actual problem.

Your Model X Air Suspension Leaks by Design — Here's What Healthy Looks Like

The most expensive lesson in my ownership-cost writeup was a single line: $5,612 for both front air struts. Both were leaking. And the part that stuck with me wasn’t the number — it was the timeline. By the time a corner visibly sagged in the driveway, the springs had been losing pressure for weeks. The failure was slow, invisible, and completely knowable in advance. I just wasn’t watching.

So after that bill I did the obvious engineer thing: I started logging the suspension pressure off the CAN bus. The first thing I learned surprised me — a healthy air spring leaks all day, every day. Detecting “a leak” is trivial and useless; the whole car is leaking right now. The real problem is telling a normal leak from a failing one.
