Air Brake Disc Rotor problems of the 2004 Jeep Grand Cherokee

13 months and a little over 13,000 miles after leasing my brand new 2004 Grand Cherokee, the steering wheel was shaking uncontrollably every time I'd I hit the brakes. I took the truck to the dealer and they said the rotors were defective, after a long discussion and many back and forth the svce. Manager at the dealer decided to replace the front rotors at no cost to me. Now 10 months later the problem returned. Went back to the dealer, but this time they tell me the rotors are damaged again, but I'll have to pay for the repair, which total cost is over $300. Now at 26,624 miles, they need to be replaced again, what's going on? after a friend of mine search the web, she found out that this is the same problem many 2004 Grand Cherokee owners have encountered. Is this a factory defect? even though Chrysler doesn't acknowledge it. Can rotors get damaged in such a short period of time, this is the second time I leased a Jeep, I never had this problem with my 2000 Jeep. Is anything being done about this?.

2004 Jeep Grand Cherokee - all four brake rotors warped at 20,000 miles of normal driving (no trailer, etc. ). Dealer machined the rotors. Suspect warping will occur again in less than 20,000 miles as less metal on rotors now. Dealer measured brake pads at 60% rear and 50% front, so those components seem ok. There is something in the design and/or manufacture of the brakes that causes warping. Fortunately, no accident.

Brakes developed vibration at highway speeds when trying to slow down. I am suspecting warped rotors which should not happen at 34000 miles.
