  • 49,742 miles
The contact owns a 2003 Jeep Grand Cherokee. The vehicle was included in the recalls associated with NHTSA campaign id numbers 06V197000, seats:front assembly:seat heater/cooler, and 09V117000, seats:front assembly:seat heater/cooler. The vehicle was repaired at an authorized dealer for both recalls. After being repaired he noticed that there was still a hole developing in the front drivers seat due to the heated seating feature. The vehicle was taken back to the authorized dealer where it was repaired a third time. The contact also stated that the vehicle would intermittently overheat. The vehicle was taken to an authorized dealer one time a year for five years consecutively where the engine fan relay and motor was replaced. The failure mileage was 49,742 and the current mileage was 150,000. The consumer also stated the driver's exterior mirror also had a problem with the heating element. Also, the vehicle had an evaporated emission leak which caused the vehicle to fail inspection. The fan relay was replaced five times, the air condition was inoperative, the check engine light illuminated. The dealer refused to cover the repair of a hole that developed in the driver's seat approximately the size of a baseball which he believed was related to the heated element problems. Updated evoq 01/27/11..updated 09-17-12 the consumer stated Chrysler has considered the case to be a goodwill case and opened up a reimbursement case in regards to this vehicle. Updated 09/24/2012

The heating/cooling system on my 2003 Grand Cherokee is an insult to the other qualities of this vehicle! the internal doors that direct air through the system is extremely cheaply made. Mostly plastic-a very poor grade! the dealer says it will cost close to a $1000 to repair and he wouldn't guarantee it would not happen again. I think Chrysler should be responsible for something this poorly made. It is no wonder they are in trouble and the government is giving them billions of dollars to make more inferior Jeep! I have not had the repairs made, I just don't have the money. So my wife has to ride to work in a luxury vehicle with no heater! there is no doubt this should be a recall!!!!! updated 10/23/09

I own a 2003 Jeep Grand Cherokee with the dual climate control and the blend doors of the heating system have failed causing cooled air out one side of the vehicle. The repair will cost anywhere from $300 (if I do it myself) up to $1500 for a dealer to fix it. This is such a huge undertaking that most if not all owners can not do it themselves. In my research I have found that around 90% of Jeep from 2000 to 2004 have this problem. This is not a small issue and the auto maker is fully aware of the failing equipment installed in these vehicles. There either needs to be a recall to correct the problem or a class action law suit against the dealer.

The contact owns a 2003 Jeep Grand Cherokee. The radiator fan has burned out twice within 17 months. The first time it occurred the contact was pulling out of a drive thru at 10 mph and the vehicle began to overheat. The following day, she took the vehicle to the dealer and was informed that the air conditioner fan relay switch failed, which caused the radiator fan not to work. The dealer replaced the fan and it worked properly. However, seventeen months later, the failure has recurred. The vehicle is currently at the dealer. The manufacturer stated that there was a recall for this failure and the contact believes it is due to a manufacturer defect. The NHTSA campaign id number was not found. The failure mileage was 56,000 and current mileage was 74,000.

Dual zone climate control in Jeep Grand Cherokee blows hot air on drivers side and cold on passenger side when ac is on lowest temperature. The car has been in several times for the same problem. The dealer just replaced everything in the dashboard to fix this problem and I am having the same issue. My major concern is that as the winter approaches the windows will fog more and ice up. The inproper heating and cooling will not defrost the windows causing a dangerous situation for driving. My wife uses this car to drive my child and I do not want to risk thier safety. There are websites all over listing people with the same problem for years.
