Events : vibration when braking. Consequences : begining of loss of control problems because of the vibration in the steering wheel and vehicle.. this is a new car with 6000 miles. Rotors replaced because of warpage at 6000 miles. Dealer said there is no cure for this problem except to put new rotors on every 6000 to 10000 miles. You only know of the problem when it too late and the vibration begins. There were also two other people at the dealer when I was there with the same problem. I have a friend that has replaced his rotors 4 times in 34,000 miles. This has been a problem since 1999-2004. Without control of your brakes you have no control. Please look into this. It is a widespread problems in Jeep grand cheorkee's.

Consumer complained about a braking problem, warped front/rear rotors. Consumer the problem fixed today. When applying the brakes the pedal pulsed and lost brake power with only 20,000 miles on vehicle. Consumer said vehicle did not pull trailers, make jack rabbit stops, or anything that would cause such a problem. Vehicle was serviced regularly by the dealer it was purchased. The rotors were turned instead of being replaced. O consumer expected this problem to recur, and felt that was a manufacturing defect.

Driving at 65 mph I came upon an accident and had to brake rapidly. When I applied the brake the car shook violently and went into an uncontroble spin and ended up facing oncomming trafic in the opposing lane. Took the car 2004 Jeep gc to the dealer to check out why this happened the dealer said the front rotors were warped and had be replaced and was not under warrentee he also statedthey get 40 or more jgc in for brake work a month.am I missing something here" ?"

The front and rear rotors, and brake pads need to be changed every 2 to 3,000 vehicle. Took vehicle to the dealers, they said it was because consumer rode the brakes. But this was fourth Jeep vehicle and driving pattern had not changed. Only 12,000 miles on the vehicle. Took vehicle to independent mechanic, who determined it was not normal.

Our 2003 model year Jeep Grand Cherokee has terrible brake rotors. The Jeep is used by my wife for a daily driver. We live in Ohio in a fairly flat area. The vehicle is driven in town 95% of the time. The vast majority of that time is on the same road with a speed limit of 35mph. It is not a congested area that requires significant and or sudden braking. The rotors began to warp around 5,000 miles. The next scheduled oil change was around 8000 miles, and we had them replaced at that point. The rotors warped severely again around 20,000 miles. At which point the dealer fooled my wife into paying them for replacement Chrysler rotors as the brake warranty was neither covered under the 3/36 bumper-to-bumper warranty nor the 7-70 powertrain warranty. If I had not thought them to be under warranty, I would have never had the dealership replace them with components of such shoddy quality that they will warp again inside of one calendar year. The service manager told my wife that rotors should only last 10,000 miles. I am an automotive mechanical engineer. I uinderstand that the factors that contribute to rotor warpage are only heat and installation. Given the use of this vehicle (we don't even have a tow package), excessive heat can be eliminated. The failure mode eliminates improper installation. Poor quality material, not enough material, and inadequate manufacturing processes could cause warpage with significnatly lower heat threashold. Since Chrysler and now DC has been having the problem for decades, and they have changed the calipers in the '02 model year, I suggest that NHTSA pressure DC to upgrade the quality of the rotors. All they have to do is shed heat and take the wear of the brake pads on their surface. It is one of the more simple components in a vehicle. I would suggest that they not only replace the rotors for all Grand Cherokee owners, but replace them with a reputable name (non DC oem) rotors. This would alleviate all issues.

Warped brake rotors at around 24,000 miles are causing a strong vechicle shudder on my 2004 Jeep Grand Cherokee when braking. This could lead to increased braking distance and a loss of vechicle control.

I have a 2004 Jeep Grand Cherokee with 15,000 miles. The front brake rotors had to be replaced at 7738 miles, and now again at 15,440 miles. The warping of the rotors makes the car unstable and I have almost been in a few serious accidents, and did have one collision due to this problem. These rotors are flimsy and should be replaced with a better quality part

Dt; front brake rotors have been replaced twice and redone once within 25,000 miles. When brake pressure is applied there is major vibration from the steering wheel. After current resurface no problems as of now.

Consumer states: Vehicle shakes only when braking. All 4 rotors are warped, at various speeds the vehicles shakes more so at 45 mph or more. Shakes more violently when braking from that speed. No indication of for warning until vehicle began to shake while braking. Diamler Chrysler will replace the front rotors, but not the back rotors, and refused to give information as one why they will only replace front, and not the back, and refuse to give information regarding deffect of rotors.

2004 Jeep Grand Cherokee on 3rd set of front rotors at 18,869 miles. Rear rotors identified with same problem and Jeep will not cover under warranty. Multiple communications with Jeep have failed to resolve issue. However, when we emailed Jeep to inquire about whether or not rotors were upgraded on 2005 model to fix brake rotor problems identified on 1999-2004 model we were informed that "yes we did update the rotors on the 2005 model Grand Cherokee and changed the vendor for the rotors." This, I believe, indicated that they identified a problem which required them to not only update the rotors but it was also severe enough to change vendors. I feel that Jeep should upgrade our front and rear rotors to either the 2005 model rotor (if appropriate) or upgrade to a different type of rotor which does not have a history of warping requiring replacement.

The front brakes pulsated because the front rotors were warped. The dealership re-surfaced the rotors and replaced the brake shoes, but the failure has recurred. This is a common failure with these vehicles, in which the dealership and manufacturer are aware of. The brake problem began initially at about 17,000 miles and became progressively worse. Resurfaced rotors at 20,000 miles and they began exhibiting problems at about 22,500 miles. Problem is continuing to worsen.

After only 11 months and approximately 7,200 miles car became difficult to control during braking at highway speeds. Brake pedal had severe pulsation, steering wheel shook harder, and car shook during all braking conditions. Dealer replaced front rotors. After 18 months and 12,000 miles, brake pedal began pulsating, and steering wheel started shaking during braking conditions. Dealer replaced front rotors again! the dealer informed me that the rotors are no longer covered by the manufacturer under warranty. I am very concerned about this problem and the lack of attention by the manufacturer towards resolving the problem. If the problem has not been resolved by the manufacturer, then am I expected to have the same problems again within 3,000 to 5,000 miles from now" and then who will be responsible for the cost" me...the consumer!!!!! the manufacturers of all vehicles have the responsibilty to provide a quality braking system in all vehicles that should work correctly and without problems.
