UPDATE:
I own a 2005 Jeep Liberty CRD. I have been having issues with the front brakes seizing up since 2007 and of course the dealer couldn't figure out what was causing the issue and they were never open when I was having the problem (I had found that letting the Jeep sit for 30 minutes would release the brakes). Yesterday I was half a mile from the dealer and the brakes started seizing. I continued to the dealer at a whopping 25 mph to have them determine that the master cylinder and brake booster were the cause of my issues(Which still needs to be fixed, but Chrysler of course wants no part of it). This morning on my way to the office I noticed that the acceleration was extremely slow and on the highway 75 mph was my max speed (Brakes don't seem to be seizing). So I have 2 questions.

1. Does anyone know where I should start looking for the cause of my acceleration problems?
Well the dealer has tracked the power issue to the 55037730AD Charge Air Cooler Hose.

2. Do people agree with me that Chrysler/Jeep should be responsible for a pre-existing issue when it comes to the brakes?
And for Jeep Honoring a pre-existing condition on warranty, HA. Actually had one of the rudest experiences with Jeep customer service. In the end it cost over $650.

Thanks to everyone that had some input.

IF you have reciepts where you've taken it in under warrnaty and got the tradritinal "No Trouble Found" when it was under warranty then you MIGHT stand a chanch sitting down with the sales manager and working your way down.

No documentation then your on your own.
I seem to recall there's been cases of the front calipers sticking but don't recall the solution.
Of course the dealer is going to recommend the most expensive parts first

X2 Joe's comment on documented visits for brake seizing with no problem found and no repair done should get you coverage. Visits to a Jeep dealer should show on a standard repair history search by VIN. I won't comment on the brain capacity of an shop, dealer or otherwise, that cannot figure out sticking brakes in 4 years. Brakes only stick because the pad/shoe does not retract enough to clear the disc/drum why is not exactly rocket sience. See pg 5-4 of the "e" copy of the 2005 from Sir Sam's NOOB guide for a discussion of causes.

Causes include 1) the rubber boots on slider pins on the front calipers are known to stick, see viewtopic.php?f=5&t=58230&p=647066&hilit=brake+rubber#p647066; 2) I'm pretty sure the Jeeps, like most of today's vehicles, have synthetic (not stainless steel) piston in the caliper assemblies which can stick from time to time (this was the cause of some very entertaining intermittent front brake sticking on my 1993 Dodge D250 Cummins complete with wheel hop due to warped rotors); 3) I'll defer to others but I've never seen or heard of intermittant sticking being due to the master cylinder or brake booster (FSM says this may be the cause for all 4 brakes sticking not just front). My bet in on cheap first especially since it's common. Pull the pins and rubber seals; grease per forum discussion; reinstall and I bet that problem goes away. The wait 30 minutes and the brakes release suggests that once stuck they have to cool off to release.

On you acceleration check your turbo to intercooler and intercooler to engine hoses for splits (remove from vehicle to check as splits tend to be on the bottom and hard to find). Samco is the best fix but 2n gen OEMs are supposed to be ok. Don't know if that would impact top end but guess that it could.
