This past winter ('07-'08), the rear driver and front passenger automatic door locks on my 2000 Jeep Grand Cherokee Laredo began to make a loud quacking noise upon locking and unlocking. Also I recently discovered that these two doors must be manually locked as they no longer lock upon automatic locking with the remote or with the master control on the driver door.

Left passenger door lock is inoperable. Makes loud sound when locks automatically activate while driving as well as when I lock or unlock the doors using either of the lock buttons on the front doors.

I have a 2000 Jeep gc Laredo, and along with many, many other people I have numerous problems. The warped rotors are very dangerous when you have to use your brakes, especially when you have children in the car as I do, also the taillight/brake light issue, that has gotten me pulled over more than once, even though I put a new bulb in it every time. The door lock actuator that is very annoying not to mention my transmission has a shifting problem that I can't do anything about and now my radiator fan will not work so my car will overheat if I am stopped for too long.

Door lock actuator on both driver and passenger(front) side failed. Unable to open with key alone. Must press keyless entry and also turn key. Actuator make grinding/quacking noise when keyless entry used. No repairs attempted as yet. Dealer cost is approx $ 250 per door. Front rotors wear excessively and quickly. Results in violent and dangerous shaking of vehicle when braking from mid-range speeds (40-45 mph). Have had rotors polished twice within 8 months.

To whom it may concern, I am writing to you about a two serious safety issues with my 2000 Jeep Grand Cherokee. First, the door locks are all starting to fail. Without warning they fail to operate and you can not unlock them. This is a serious safety issue if a rescue worker can not get into my vehicle to rescue my children. Second the rear brake lights continue to fail intermediately. This could cause a grave accident killing me or my children in my vehicle. I have talk to twenty to thirty Jeep owners of this same model and approximate year and they all have the same problems. You have to go to this web site; P://www.carsurvey.org/viewmorecomments_review_33943_4.html. this site lists over 700 complaints, most of them with the door locks and brake light. These parts are obviously defective to have such a nationwide outcry. Please investigate these problems and Chrysler recall all affected vehicles. Thank you for your attention.

Blend doors on the 2000 Jeep Grand Cherokee climate system were broken at the time of purchase, dealer would not warranty items, claiming it was an isolated problem and not an ongoing problem with Grand Cherokee, and quoted me $1200 to repair them, and to expect them to go roughly every 2-3 years. It seeemed to me like a manufacturing issue and customer's should not be liable for covering it. Apparently it affected 1999-2004 models, so it was a recent model.

I have a 2000 Jeep Grand Cherokee. Since July 2004, there has been problems with the power door lock solenoids, one after the other. As of this reporting, I have had to have all the power lock solenoids replaced, including the back hatch which was replaced the Monday prior to this writing. The problems started with the rear door solenoids, left door first, then the right. Problems were significant enough with the rear doors that they could not be opened from the outside after they failed - only from the inside by manually unlocking the door (the outside does not have a key slot). I have incurred almost $2,000 in repair costs over the last 30 months replacing the mechanisms. The same repair shop replaced all five units, and all five replacements are currently functioning. They furnished me this website to contact due to the trouble that I have seen.

The passenger side front door lock of my 2000 Jeep Grand Cherokee failed in such a manner that the door could not be opened from the inside or the outside. This turned out to be only a inconvenience for me, however if this happens during an emergency someone could be trapped inside the car.

No one was killed, potential lock out of vehicle.

: the contact stated that the door actuators on the vehicle would not move the locking mechanism to lock or unlock all four doors. This defect caused the door locks not to unlock when locked and vice versa. The vehicle was not taken to a mechanic for inspection.

Driving with my daughters to the beach when suddenly my steering wheel froze as I was along a winding road. Towed truck to a mechanic who diagnosed that the gear box was broken at that point he repaired the gear box. Approximately 1 week later the same exact thing except that the truck caught fire, again towed the truck back to mechanic who replaced the gear box. I thought I was going to die when I experienced my steering wheel freeze and the fire was extinguished quickly so minimal damage was suffered. In 1 year that I own this vehicle the radiator has also needed to be repaired, the locks on my driver door stopped working, the fan in the cooling system has stopped working, I have been told that the muffler was improperly installed. I never expected so many faults or so much money spent in repairs on a so called certified used vehicle.

: the contact stated the door locks have failed multiple times. There is a buzzing noise prior to the locks completely failing and there is no manual lock. The dealership has replaced the actuator three times and the consumer is currently having problems with the locks. Updated 5/22/2006 -

1. normal day activities such and using the lock or unlock button on the door panel or remote control to unlock or lock the doors. 2. the door fails to lock or unlock the door and it makes a loud buzzing noise. Sounds similar to a duck quack, it is very loud. This can interfere with the child safety lock functioning properly. 3. the driver's rear door lock actuator has failed and needs to be replaced.

Purchased the 2000 Jeep Grand Cherokee in May 2003. I was filling up my car with gas when someone else asked if I ever had problems with my brakes. At that point I didn't. in April 2004, I was driving on the highway and noticed that the car would shake uncontrollably when applying the brakes. Didn't shake as bad in city driving. I went to my local car repair shop and they told me the rotors were warped. Paid to have the rotors spun. Now it's a year later and the car is shaking uncontrollably on the highway. Didn't think I was going to be able to stop from hitting the car in front of me. Now I have done research on the internet and see that this is a known problem and that it is listed in the technical service bulletin from Jeep in 2002. This is my family car! I too have had to replace the 2 of my door motors and 1 of my window motors. I can't believe that there are this many complaints and no one is forcing Jeep to put a recall on the rotors.

Power door locks on our 2000 Jeep Grand Cherokee Laredo are not working correctly. Not only is it annoying, but often when someone is in the car the door locks will lock you in and you can not get out. You can't even manually unlock the doors. What if there is a fire?

- Concord, NC, USA

The vehicle was equipped with automatic door locks. The rear passenger doors will not allow entrance from the outside. Owner took the vehicle to the dealer, and had the passenger side rear door repaired. Currently, the driver's side rear door was defective.

I have already replaced 3 door lock "actuators" on my Jeep and on my way to replace an already replaced one (driver door) to make the total 4. after looking on your website it looks like this is a very common problem. The response I got from Jeep is that my vehicle was out of warranty. This is very frustrating since I have had a multitude of problems from this vehicle. The date of incident is only my most recent. I hope that something gets done and Jeep does not get away with faulty equipment in their vehicles.

1.)the door lock actuators on our 2000 Jeep Grand Cherokee are all failing. There are plastic grinding noises that ultimately lead to complete automation failure..)the consequences of this failure is that it is not possible to lock the vehicle doors, or unlock the effected doors. The consequences are also that the auto door locks are not operational. If the vehicle were in a crash the doors might either be locked closed, or the doors might fly open because they cannot be locked. The auto door lock feature that the Grand Cherokee has when the vehicle is moving would be rendered useless. 3.)the driver door actuator has been replaced with no help from daimler Chrysler. The rear driver side has failed, the rear passenger is about to fail. They have not been replaced yet due to the high cost associated with this repair.
