When you're sitting at a long stoplight, with the engine off, the AC is not working.
If it's 110* or more (as it frequently is where I live) this is a problem.
It's the Bilsteins they're garbage.
I had the same thing happen on my Hellcat with the same type of reservoir Bilsteins.
After only a few thousand miles all four shocks on my Bronco showed signs of leaking.
They aren't worth replacing.
Just use this as an opportunity to get some quality shocks.
I have Xpel on the whole vehicle. I have azure grey and if you have tricoat paint I would recommend it. You're not going to get a quality paint job for less than the cost of PPF.
I also take mine through the carwash (gasp) weekly, sometimes biweekly. It's holding up but I don't care if it...
Sorry man it's a terrible sounding V6 (I'm talking about ALL of them yours, mine, everyone's)
Here I found a three hour video of all the aftermarket and oem exhaust sound clips.
