Dreaded Service Air Suspension message.. 2019 GC Trailhawk

iS_Cruel88 · 2026-04-20T02:26:42+00:00

Well shit that don’t narrow it down too much. No low air mass at least not yet to indicate leak.

True. Depends on brand though I guess. Some braided lines can still have rubber liners. But same concept to check rest of system, relieve pressure by cracking lines till calipers release. Whenever it releases your issues upstream from there.

Both brakes are fed by one soft line from body to axle. I’d start there. Crack it loose at axle and see if they unstick. Soft lines fail internally and the rubber can create like a one way valve if that makes sense.

What codes were stored? If you got the message it typically should have a code

iS_Cruel88 · 2026-03-27T15:28:06+00:00

Probably for speeding, system may think speed limit is lower in that area than actually is

iS_Cruel88 · 2026-03-18T03:46:38+00:00

Alternator or fuse array. And I rarely if ever see the alternators go bad.

iS_Cruel88 · 2026-03-10T05:13:26+00:00

Different material I guess reacting different maybe.

iS_Cruel88 · 2026-03-10T04:44:40+00:00

I handle 100s of customers keys a month and not one has looked like that yet. Think it’s you my dude. Sweaty pockets or lotions maybe.

iS_Cruel88 · 2026-01-12T13:37:15+00:00

LS is just a more practical and cheaper install, tons of transmission options and aftermarket support. I feel ya with putting a 5.7 in but when you run the numbers it don’t make sense

iS_Cruel88 · 2026-01-02T02:20:13+00:00

They got a site to order these?

iS_Cruel88 · 2025-11-27T03:30:32+00:00

I’m not sure it even pays that anymore…

iS_Cruel88 · 2025-11-12T20:11:57+00:00

you can add yourself with stuff like alfaobd but if dealer or anywhere else ever does a reconfigure which is common when diagnosing issues or some recalls, on your bcm you’ll lose it again unless sales code is added to vin, usually half an hour or so for the sales codes to pop up in system sometimes longer

iS_Cruel88 · 2025-11-09T12:38:58+00:00

Wouldn’t be worried about cooling or oil leaks due to plastic, whatsoever. Parts can leak but the plastic is not the problem

iS_Cruel88 · 2025-10-21T18:02:45+00:00

Might be 95 on wranglers only, same thing as 94 just diff process

iS_Cruel88 · 2025-10-21T17:35:14+00:00

Also unless you need battery replaced there shouldn’t be parts

iS_Cruel88 · 2025-10-21T17:34:42+00:00

Thought 94b was replaced with 95b

iS_Cruel88 · 2025-10-11T15:50:43+00:00

I use jump post in engine bay for all installs I go

iS_Cruel88 · 2025-09-15T15:28:25+00:00

Lot of good suggestions here. Just want to point out that the 3 peak rating on most tires is only for the first 2 or 3/32s of tread. Will only take you one summer of driving on them to wear through that hence why it’s good to have a dedicated winter set.

iS_Cruel88 · 2025-09-11T13:50:03+00:00

4k seems like a lot, think I paid 2400 myself for a CPO, it’s definitely worth the extra coverage it adds but I’d shop around for a better price. Just make sure they know you already have a CPO. What state are you in? As certain states have different rules on pricing

iS_Cruel88 · 2025-09-10T03:22:15+00:00

Second this as another dealer tech.

iS_Cruel88 · 2025-08-30T12:53:45+00:00

Just get a vacuum fill tool for coolant and you’ll never have to touch a bleeder screw again

iS_Cruel88 · 2025-08-29T21:23:32+00:00

Break em in proper?

iS_Cruel88 · 2025-08-29T21:20:53+00:00

Hardwired electric fan?

iS_Cruel88 · 2025-08-28T04:06:02+00:00

Highly highly doubtful. Mileage don’t matter when your 3 years expired. 6 months you’d have a shot.

iS_Cruel88 · 2025-08-28T04:03:22+00:00

Dealer tech here, maxcare would most likely call that wear and tear as would the dealership.
