1999 Jeep Grand Cherokee: engine overheating

Filed Apr 5, 2017 · Brakes · OR

Both front brake calipers and left rear caliper seized causing overheating to the entire braking system. It also caused rotor damage,disc damage and brake pad damage. This is not the first time this has happened. I am not sure if it happens when I am driving or stationary. I have had to replace my pads once a yea since I have owned the vehicle and I have replaced the hubs discs and rotaterstwice. I am preparing to replace all of these components for the third time and will also replace the rubber brake lines. I have been researching this vehicle and have come to the conclusion that there is a severe problem with the braking system. In my opinion it is only a matter of time before someone loses their life from this defect.

One day I was on my way to work and the heater on the passenger side was blowing cold air. The drivers side was warm air blowing. I took it to the shop to be fixed and it cost me $796.00. Once I started telling people what had happened it seemed like any one that had a jeep had been through this expensive problem just to have heat in your vehicle in the middle of winter and no extra money to fix it right away. I think this should be a recall on jeeps for the actuator and blend doors. I think I should be refunded for the cost of this bad/poor design on jeep's. Also the electric door locks. I was leaving work one day and went to unlock my door and it would not unlock. I had to call a lock smith to get it unlocked, only to find out the electric door switch went bad in it. That cost another$185.00. I also hear this problem happens to alot of jeep's. Now my heated mirror on the drivers side is all messed up and you can not see out of it clearly and it will not defrost. So now it looks like about another $100 or so to get that fixed. When I first bought this jeep about 1 1/2 years ago the fan that cools the motor went bad and was causing the motor to overheat. That cost another $200 to have that fixed. I think some of these items need recalled and give these people with jeeps some of there money back because of all of the problems that we have had with them and all these things seem to start around 100,000 miles. Something needs done.

Front left and right calipers seized causing caliper, pad and rotor overheating and brake rotor cracked and failed causing me to scrape a guard rail while attempting to stop. This is the third brake caliper related failure I have had in the last 24 months. The previous 2 resulted in my replacing calipers rotors and pads. Jeep is aware that the calipers are defective and would replace them with an upgraded different type but only while vehicle was under warranty. There are dozens of reports on line at various forums of this exact same problem. I have ordered the upgraded caliper (now that I know about them) and will replace this but jeep should notify all owners of this known issue so that we do not continue to replace a known bad part with the same known bad parts. As I consider this dangerous a recall would not be out of the question either.

On a recent day-long trip, the electric seat heater on driver's side overheated, causing a 4" diameter badly blistered burn on the back of my leg. A recall for this defect was issued on 4/7/2009 for 2001-2004 models (the federal safety agency campaign number: 09v117000 ), but I was not able to find one for the 1999 grand cherokee limited. The local dealer (lithia in grants pass, or) requested I submit this so he can make the proper repairs free of charge as specified for the 2001-2004 models.

The "blower control module" is the electronic component responsible for adjusting the fan speed for the HVAC on vehicles equipped with the automatic climate control. It is a well known problem that these units fail. It has failed on my vehicle. My own independent mechanic has replaced quite a few of them. The wiring harness and plug that supplies power is not heavy duty enough and it overheats and melts and could cause a fire. It can be further exaggerated if the blower collects debris and draws more current. Once it fails the blower will no longer operate. This makes the defroster unavailable, which could create very unsafe driving conditions should the windows fog up. Chrysler has a redesigned unit with a new harness so it is obviously a problem they are already aware of. I'm in the process of having the new parts installed and the old parts will be available. Here's a write up of how to fix it yourself. Http://www.wjjeeps.com/blower_motor.htm

Dt*: the contact stated the vehicle transfer case in the engine shifted from 4 to 2 wheel drive. This has been a problem since the contact acquired the vehicle. The contact also expressed the vehicle overheated, but the vehicle has not been to a service dealer to evaluate or determine the problems.

My 1999 jeep grand cherokee's radiator fan failed to work, causing the vehicle to overheat. This was diagnosed as an inoperative fan relay by a jeep dealer. This issue is one of many intermittent mechanical problems plaguing this vehicle since purchasing it new, however this complaint is being filed for 4 specific reasons: 1) this type of problem resulting in total failure should not occur in such a new vehicle, 2) a breakdown of this type (overheat) may cause collateral damage to the vehicle which will not be known about until a future event occurs, 3) I am a women who travels alone often and any breakdown puts my personal safety at risk, 4) to help prevent others from experiencing this if this report assists in determining that this issue is a systemic problem with this vehicle. I understand that proactive resolution of this problem was not likely, however I have attempted to find out information on systemic problems with 1999 jeep grand cherokees in order to be an informed consumer and be proactive in my maintenance checks of my vehicle to avoid breakdown. This information is not readily available from the dealerships, therefore it puts the consumer at more risk than necessary. Daimler chrysler should take more responsibility and improve communication on these issues. This model year vehicle has been plagued with known problems, two of which cost me the loss of my vehicle over 2 different weekends, 2 different breakdown events while I was driving alone, in addition to at least 12 other service events.

The vehicle exhibits a sag/hesitation following a partial cool down restart, possibly an oxygen sensor problem. While making hard left turns at slow speeds (such as a u-turn), the airbag warning light illuminates and a audible chime is activated. The right side brake light assembly is burnt (internally) due to some kind of electrical overheating. The vehicle shifts hard, misses shifts, shifts repeatedly at constant speed and on a level grade. The rear differantial "bumps" very hard within 3-20 seconds of coming to a complete stop. An immovable "fog" has developed on the lenses of the composite headlight assemblies.

While driving, could step on the brake pedal and feel the brakes pulsating. Also, had noticed rotors overheating and got out of round. After every eight thousand miles, rotors had to be replaced. *ak consumer feels the brakes are underdesigned and needs to utilize a splash shield to aid in the cooling of the brakes.

Brake assembly overheats causing warpage of rotors and subsequent steering shudder . Rotors are warping every 10,000 miles. Dealer has tried to correct problem with one replacement and three machining applications, two concurrent. Dealer has admitted this has been a constant problem in grand cherokees and has refunded money for last two brake refacings, but cannot guarantee the problem will not persist. Chrysler has not been helpful or sent technical representative to investigate. I believe this is beyond the ability of the service department to solve. I feel this is a safety issue because the shudder becomes violent at highway speeds when braking and vehicle could loose directional stability . This is only one of many faults with this vehicle (others the dealer has corrected, to their credit).
