Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2004 Jeep Grand Cherokee Owner Comments

problem #5

Grand Cherokee

  • 54,000 miles


I first noticed the problem nine months ago during a long drive with the A/C running, that the condensation under the front passenger area was enough to cause a very small and slow drip of water. I have taken the car to a couple auto shops and both mechanics suspected that the drain plug was defective, yet the condensation did drain towards the outside of the car and they could not find the source of the water leak. The carpet would become soaked in the front passenger area after long drives with the A/C running. The dealer has told me it will cost roughly $1700 to get this repaired and this is too costly for me. A mechanic friend has advised that this sounds like a manufacturer defect as the car only has 54,000 miles and I've never had any other issues. This occasional drip has grown progressively worse and last week, during a 3 hour road trip, I ended up with a pool of water in the front passenger area - enough water to have to scoop it out several cups of water! that is ridiculous. I stopped at yet another auto repair shop and was again advised that this is a manufacturer defect.

The heating/cooling system is dysfunctional and has not worked correctly since purchase in 2004, but is worse now than previously. Unable to set at one temperature and have uniform heat/cooling (depending on season). It will blow really hot, then cool, then not at all on one side and the other side is totally not insync with the driver's side (there are dual controls). Today, driving in 50F weather, control set to 71F and the air conditioner came on driver's side, nothing on the passenger side. The blend doors have been replaced in January and the water pump with thermostat have been replaced in March, and it still does not work properly. At times it becomes very hot and smells hot. At other times it is freezing cold--there doesn't seem to be any in between.. at the time of the initial service the mileage was 52000, the second time it was 55000 and now am at 59000+. have contacted Chrysler customer service center with little satisfaction.

HVAC blend door: The blend door for the passenger side has failed. I found numerous websites dedicated to similar failures for other Jeep Grand Cherokee owners. It is very apparent that this is a design problem.

Grand Cherokee 4WD 8-cyl

  • Automatic transmission
  • 37,500 miles
The contact owns a 2004 Jeep Grand Cherokee. The contact stated that she is experiencing failure with her vehicle's power windows. She stated that her power windows fail to roll up. She has not contacted the manufacturer or the dealer. The heat shut off while the heat button was still activated. As a result, the air conditioner is not working either. The dealer stated that the cause of failure was the heating system and would cost $2,000 to be repaired. The dealer also recommended that she notify NHTSA to determine if there were any recalls on her vehicle. There were none that applied to her vehicle. The engine size was unknown. The current mileage is 38,830 and failure mileage was 37,500.
