2002 Grand Cherokee
98000 miles and have only had to turn the front rotors so far. No new pads (front or rear) have been needed. Only issus with the vehicle so far are: tires at 78k miles, power steering hose and rear shocks (did them myself in under 30 minutes. Pretty good vehicle so far :)
Not sure if it applies to this problem, but 'warped rotors' generally is a myth. It is ususally an uneven build up of brake pad binding resin on the rotor which causes the brakes to grab and let go. Of course machining or replacement fixes it, but so too will cleaning the rotor &/or switching to better quality brake pads. Mostly its poor quality brake material or excessive/erratic/undersized braking that causes it.
To warp a disc rotor it has to get glowing red hot and even then it's a maybe and it will not 'jerk the wheel' out of your hand.

You must not own a Jeep. The rotors do get hot and that is why they warp.
I own a 02 GC Limited V8. Bought it new in 5/02. No issues with brakes at 65000 miles. Just changed pads. The rotors still are within specification. Since Jeep used two suppliers for calipers and pads on the '02 GC, makes me wonder if the difference the owners are experiencing is due to the OEM equipment installed on their Jeep. Based on reading many reviews, I would recommend a caliper change if you are only getting 10k on a set of brakes/rotors, I do not believe the dealer explanation that some drivers are causing the short life with their driving habits.
Just came back from the Jeep dealer AGAIN! I'm so tired of my 02 GC I could scream! 67,000 miles:
Rotors replaced 3 times; only once under warranty.
Motors replaced in 3 windows ($400 each)... one more to go.
This is my second and LAST Jeep!
I own a 2002 Jeep GC Ltd. Brakes have "squeaked" since the time it reached about 20,000 miles. We purchased it new. Dealer initially said that it was "brake dust" causing the noise, so they cleaned the brakes and put on some kind of solution which is supposed to quiet the squeaking. So far, so good... for about a month. Squeaking returned. More trips to dealer. Same remedy. No one mentioned warped rotors or anything of that nature to us. We finally resigned ourselves to living with the squeaking, as no fix could apparently be found. No further brake issues, but the posts here concerning warped rotors has me concerned and I shall be vigilant, in the event this happens to my car also.
Next, came a heating problem. One side of the vents began to blow only cold air, when the heat was on. A major issue in Winter. We had to shell out for this fix (twice), ourselves. First it was the driver side and then later, passenger side. The Jeep is not used for daily commutes so only has about 47,000 miles on it. Unfortunately, the bumper to bumper warranty had expired when the heating issue initially happened and Chrysler refused to cover it, of course. I vote that it's all the inferior crap (in addition to rush jobs on design and engineering) which manufacturers use anymore, which leads too many of the recalls and many other issues not included in recalls. My heating issues were due to some cheap plastic parts falling apart on the heater system. In fairness to the people at Jeep, it's not just them... all cars seem to suffer the same ridiculous issues of poor quality parts falling apart, just about the time the full warranty expires. Either that or the driver's driving habits are called into question, as an escape route in denying responsibility.
We've had two recalls on the Jeep thus far. Was reading of others on-line, but we never received notices of them, so assuming that our particular Jeep wasn't included? No idea. Plan to ring the dealer this week to have them run a check of any recalls which may pertain to our Jeep, just to be safe. Otherwise I've enjoyed driving my Jeep, but likely will get a different make, when I trade it in the Spring.
Am hoping that you guys with the warped rotors find a solution soon. My thought is that it appears to be so very common that Chrysler should INDEED issue a recall to remedy the issue! Heat is one thing... squeaky brakes are another, but something contributing to potential brake failure or poor brake performance, is clearly a safety concern and should have been addressed some time ago! So shame on Chrysler that this is still happening!
Thanks for letting me put my 2 cents worth in here...

I think people commenting should state which motor is in their car. Perhaps that would help establish a thread. i.e. Hemi's or V8's with brake problems, etc. I own a 2005 Grand Cherokee with 41k and the 3.7L V6. Not a single issue with the brakes or anything else of significance. Only maintenance I have done is oil change every 5K. Had the computer reprogrammed because of sluggish shifting - under warranty and took 15 minutes. Car runs great; would buy another, but would like better overall gas mileage. Gets 16 MPG overall with 19-20 on the highway. Not really all that bad for a 4,000 lb vehicle.
I have a smell of anti freeze inside my 2002 Jeep Grand Cherokee (8 Cyl) and a film on the inside of the windows. I am pretty sure I have a leaky heater core and based on some research, believe it will cost about 1000 dollars to fix. It is also not a do-it-yourself type problem because of the difficulty in getting to the heater core. Anyone have similar problems? I also have the front brake rotor problem, but it is not severe enough to replace the rotors yet. I am hearing a few unusual sounds in the drive gear. I like the veh so far as long as I don't hear of common major problems, I plan to keep it and pass it onto my daughter this fall - she is about to get her license.
I own a 00 Grand Cherokee with an i-6, and had no problems with brakes until we changed the front rotors and pads due to squeaking. Still happened, so we changed the back rotors and pads. It ceased for a month, then we started feeling a shaking up front and through the steering wheel. I changed the front rotors again and noticed blueing sporadically around the rotor surfaces. It was also smelling hot at the front wheels and actually smoking! This current set (3rd) is showing the same symptoms in about a weeks time. It feels as if they are fine at first, then shortly into a drive they start swelling from continuous contact between the rotors and pads. I believe the calipers are not releasing fully and the continuous pressure(brakes always slightly applied)is heating then warping rotors. You can actually feel the drag increase and you can watch the overhead fuel economy mileage numbers go down to around 7 mpg! The dealership says my vehicle has no brake recalls on calipers or rotors.The undersized rotors theory sounds viable also. I have owned several Jeeps (89,90,00Cherokees, cj-5s, a Commando, J-20,and this 00Grand) and I find it sad from an enthusiast's point of view that Chrysler has let this obvious problem with their product go on for so many years!
I replaced the rotors 5 times in 6 years, I try to time it so I am only paying for every second one. if its within the year that the warranty covers the rotors unfortunatly I paid for the last 4 before I caught on. I had trouble with a Ford product once and never bought another one it looks like Jeep will suffer the same fate.
I bought my 2005 Jeep Grand Cherokee Limited V8 in February 2007 and still own it. I so far have not had any problems with the brakes. I do remember over the summer them squeaking some, but after having them checked it went away.
However, I am having a problem with what sounds like the rear-end. It "hums" when you give it gas and when you accelerate more it tends to get a little louder and then eventually stops. It used to be so loud it hurt my ears. They've checked the rear-end and say it has a new one and that sometimes when you put new ones in they hum?? It also grinds every now and then, I had it to the garage the day before yesterday because it sounded like the rear-end was coming out. They couldn't find anything and say it could be the transfer case. Has anyone else had any type of problems like this?
I own a '02 Grand Cherokee Laredo with an I6. It has been a nightmare since I bought it. Let's see. I lost my cooling fan relay, which caused my cooling fan to blow. $800 later I had that fixed. Then I had my rotors and pads replaced (front only). Then 13 months later my cooling fan blew again. Chrysler wanted me to pay. Needless to say that didn't happen (I snapped). Then just 6 months after the new brakes went in, the rotors are warped, and appear to be sticking. I feel like I'm towing something and the fuel economy has gone completely downhill! Needless to say I'm going Japanese from here on in!
I also own a 2002 Jeep Cherokee limited V8 with VERY bad brake problems. So we took it to the dealership only to find out to fix the problem would cost us a lot more than what we can afford. The dealership did tell us that this is an on going problem with Jeeps and that we needed to update the front calipers along with new rotors. Chrysler is very aware of this problem, they are just choosing to do nothing about it.
FYI To those who are not having break problems, there is no way the same problems could be happening to so many different jeep owners and all due to "bad" driving habits. This is a WELL known problem with Jeeps.
I have a 2002 Grand Cherokee Limited,4.7L H. O V8 with 93000 miles. I like the car. It has maintained a good appearance, is a comfortable ride, gets 23mpg on the road. I have had three significant problems.
The Front Brakes, vibration when braking at 60+. About 18000 miles between the need to resurface or replace front rotors. There is/was a class action suit that covered repairs for 36000 miles but my problem still persists.
Have replaced Multifunction switch 56042302AG three times. Problem draws down the battery, car won't start etc.
Last evening I walked out of a restaurant to find the drivers side front window down. It would not move up. The front passenger and driver rear windows have had the same problem, all within the last four months.55363286AD Regulator has had to be replaced. Has this been a problem elsewhere?
I intend to keep the car, any other problems I should anticipate?
I purchased my 02 GC Special Edition in Nov. of 02. Had to have the rotors turned twice so far. Need to have them turn/replaced again, it has started the very bad vibration again. First time was just outside my 36k warranty and now I have 64k miles on it. Plus, my Jeep has always seaked and made loud noises evertime I go over any type of bump.
Today my Jeep is at a local repair shop getting the third electric window fixed. The regulator/motor is not working. Only one more window to go. All three within a 2 month period at $348.00 a pop! Plus I have noticed a small motor oil spot on my garage floor. My local repair shop says I need to replace my valve cover gasket. Again I only have 64,000 miles. Seems very strange. Well look into this. I have always maintained all of my cars and normally keep them for 8-10 years (to get the most $ out of them) I am very thankful that I did not pay any interest on this SUV back when I purchased it new! My other car is a 11 year Honda which I have not had any problems with except for one A/C issue. I not buy another Jeep and will be looking at Honda again.
