While the latest tundra does offer it, it's a very recent development. Sequoia did not sell much and idk how much it sold the most expensive version with air suspension.
Hopefully you are still in warranty. My suspension failed at 69k miles -- out of warranty. It was not a cheap repair, costing me $6k. To me, this feels like a design flaw.So I have noticed for a few months now the front suspension often has to raise up usually at the first stop I make when driving after it's been sitting a while, like overnight or when leaving work. I didn't think much of it but we went on vacation for about 9 days around New Year's and the truck sat in my garage plugged in the entire time. My first drive back the front passenger tire was rubbing on the wheel well when turning until it raised back up.
So while it was in for the rear suspension recall this week I asked them to take a look at the front suspension. The report says they verified there was a "low leak" on the front right damper but it was an "acceptable" level and no repair was made. The SC has been great at fixing minor issues for me the last time I had it in but this is a bit odd to me. How can a suspension component have an acceptable level of leaking?
I’d definitely keep bringing it up and seeing if you can get a replacement. For perspective, assuming the airbag drops six inches over ten days it’s only a loss of .025”/hour which is quite small. For a daily driver the loss of less than half an inch per night wouldn’t be much of an inconvenience.
I read that someone here bled it without special service equipment, but I don't know how. I think it must be done with a vacuum pump and software.
It's true that the hydraulic and air systems don't "mix" but the airbag/damper is one assembly. Sometimes an air leak is somewhere other than the airbag itself though.
