Sorry, newbie questions. Can you please share your experience about replacing the shocks? What were the symptoms that indicated the air suspension was going bad? Were all four replaced at the same time or at different times over 45-55000 miles? Were all air suspension components covered by the warranty, i.e., nothing was considered to be a wear/tear item?

 

All of my air shocks were replaced under original warranty by the previous owner before I bought the car. The Right Rear shock was replaced at 41,363 miles, the Left Rear shock was replaced at 47,037 miles, and both front shocks were replaced (along with the upper control arms) at 57,999 miles. Here are the complete details from the MyLexus web site service history:

My RF air strut died at 48k and was replaced under warranty. Nobody makes a truly reliable air suspension, but Lexus is the best from that perspective.

I was just thinking about the advantages of air suspension while driving the 2011 Sport to work this morning. 4-corner auto-level, self-lowering at highway speeds for better aerodynamics, HEIGHT HIGH setting for steep driveway entrances and bumpy dirt roads, adjustable shock damping, and a softer ride vs. the standard coils. But on small ridges and broken pavement, the 19" tires cancel out some of the advantages of the air suspension vs. the 18s with their taller, more compliant sidewalls. I was thinking the ultimate for ride quality would be a 460L with air suspension and the 18" wheels (and probably Michelin tires). The only way to get a softer ride would be to somehow put 75-series tires on it. Speaking of that, I test-drove a Town Car way back in 1990 and that was the softest-riding car I've ever driven - it had air suspension, soft shock tuning, and 75-series tires.

 

I have been intrigued by the same thought: 18 inch wheels on my 2014 460L for an even cushier ride. Are there any out there? I would love to see pics

 

I had a 2004 LS with air suspension and only changed the right rear strut once in 12 years.

 

Is there any warning before the air shocks go bad? Can they totally deflate unexpectedly?

 

When my LR air shock I can't say it totally deflated but I noticed a thumping/bumping noise coming from the rear. I would hear this noise going over speed bumps and even small potholes. I though my spare tire or something in the trunk was loose but noting was. I had this problem on another vehicle that I owned and somewhat knew what the problem might be. It was covered under my extended warranty.

 

The 430 was especially reliable with the air struts. I went to 148k on my UL without any issues. I also have air struts on the A8 which just hit 60k miles. On the Audi I am told they are pretty reliable and should expect 100k+ miles out of them. We shall see.

 

I have about 82,000mi on my 460L and was concerned about when I should expect to replace the Air Struts. But so far so good. And I can still feel a difference between the "Comfort" & "Sport" settings.

 

Mine are holding at 85K as well, but I certainly have a rainy day fund for if/when they decide to quit on me. If they hold out long enough I may just apply those funds to a real air setup.

 

I have encountered the check air suspension light on mine it is a 2015 LS 460 FSport. I took it into the dealer and they said there seems to be water in the Height Control Sensor. Has anyone on here encountered that? I just got off the phone with Lexus Corporate as the dealership is saying this is not covered.

 

well it’s a cheap part if you have another reliable place to fix it bring it there to have it fixed. I only bring car to dealer for warranty recalls and diagnosis. Anything that is out of warranty I don’t let them touch.

But it you don’t have a reliable place that you can hold liable for f ups then I would just try and negotiate a lower price or press harder...

i just got lexus to pay for all my direct injectors when I sent the car in for all the 3 recalls, where I am at that costs 4800 usd lol for a 2007 car so you know, the art of the squeeze you either know how to do it or you don’t.

 

Per them the part alone is over $2000 so i am not sure if he named the wrong part. Also the car is under warranty they are saying that part isn't covered as there is water in it, it didn't fail on it's own. That car is under factory warranty still then 2 years of cpo then 5 more years after that.

I am awaiting a call from corporate and i will go from there. I am just trying to find out if anyone else has encountered this issue. In my opinion there has to be something that was not put back right at some point on the car that is causing a leak because my car has never been driven through water or sitting anywhere where water could rise to that level since i have had it.

 

has that area been worked on before? By them? If so you can make that argument with corporate

 

At 106K miles on 2013 LS. I think I hear a metallic clunk once or twice while slowly going over a speed bump. Wondering if mine is starting to show symptoms. Yes, torrential rainy day fund set aside.

I wasn't aware there is such a sensor and indicator for the air suspension.
