2002 Jeep Grand Cherokee Problems

What owners report

Owners of this model year report most often about the air bag warning light and air bag control module recalls, usually on high-mileage vehicles, and about the dual-zone climate system losing heat or defrost on one side. Cooling fan failures that damage the radiator and heated seat elements that get too hot are also recurring themes. Many complaints describe symptoms appearing gradually or in cold weather rather than suddenly.

1. 1
   Air bags

   Air bag warning light on / air bag control module

   • 406 complaints (28%)
   • median 125,000 mi at 12.4 yrs old (173 state mileage)
   • 41 mention a crash, fire or injury
   • owner-quoted repair $500 (median of 9 quotes)
   • filed 2002–2025

   Owners describe the air bag warning light coming on at startup or staying lit intermittently while driving, sometimes with a chime. Several complaints say the vehicle was covered by a recall for the air bag control module but the dealer could not perform the repair because parts were unavailable, and some say the light remained lit even after the recall work was done. A few complaints describe air bags deploying without an impact, or not deploying in a collision. Mostly reported between about 70,000 and 210,000 miles, with many owners noting the light appeared on a vehicle they had owned for years.

   What to check: Ask whether the air bag control module recalls were completed and get the paperwork; watch that the air bag warning light goes out after the bulb check on a test drive. If the light stays on, have the module codes read before buying.

   2 excerpts from owner complaints in NHTSA records

   “On april 14, both of my front airbags deployed without reason while the car was idling stationary in drive with my foot on the brake. I was in the drivers seat and my two young boys were in the backseat. Fortunately, nobody was significantly injured. I suffered a bruised knuckle, and something flew in the back seat and hit my son in the head, but no injuries were significant enough to warrant a doctors visit. The damage to the interior of my car is significant. …”

   NHTSA complaint #10980230, filed 2017-04, 182,000 miles

   “I own a 2002 Jeep Grand Cherokee and both of the side curtain air bags deployed while I was driving. There was no impact or collision. I was making a right hand turn when the air bag light came on. Immediately after that passenger side curtain air bag deployed. Then a couple of seconds later the driver side curtain air bag deployed. I pulled into the store parking lot and had the car towed to a service shop. Insurance investigator determined it was mechanical failure.”

2. 2
   Visibility (wipers, defrost, mirrors)

   No heat or defrost on one side (blend door failure)

   • 305 complaints (21%)
   • median 70,000 mi at 5.5 yrs old (256 state mileage)
   • 17 mention a crash, fire or injury
   • owner-quoted repair $1,100 (median of 89 quotes)
   • filed 2002–2018

   Complaints describe the dual-zone climate system blowing cold on the passenger side or losing heat entirely, so the defroster clears only part of the windshield. Owners say the repair involves the blend door actuators and often requires removing the dashboard, with quoted costs of roughly $1,000 or more. Some owners report the problem returning after a repair. Typically reported between about 60,000 and 120,000 miles, most often noticed in cold weather when defrost is needed.

   What to check: On a cold start, set the blower to defrost and check that both sides of the windshield clear and that both zones respond to temperature changes. Ask whether the blend door actuators or climate control head have been replaced.

   “No heat on passenger side in january 2007, september 2007 no air both sides, then november 2007 no heat at all from both sides. The Jeep has been in and out of the dealer all year with many issues, as employee of chrysler , I love my Jeep that I purchased new, just not happy with the repair work needed all the time .”

   NHTSA complaint #10254032, filed 2009-01, 67,000 miles

   “I have been having troubles with the blender doors closing all the time on my 2002 Jeep Grand Cherokee limited. I have had the SUV for not even 3 years and the doors have closed 4 times already. 2 months ago they closed and it cost $1,200 to fix it, now 2 months later the doors closed again today 5/27/10. This is getting out of hand. These blender doors have a defect and chrysler is not doing anything about it.”

   Engine cooling

   Cooling fan blades break and damage the radiator

   Mentioned in 10 of 60 sampled complaints

   Owners describe a loud bang or pop followed by coolant loss, with pieces of the plastic cooling fan found under the hood and the fan shroud or radiator cracked. Several say the fan, shroud and radiator all had to be replaced, and some report overheating afterward. Complaints mention an existing recall for the cooling fan and that their vehicle was not covered by it or that the failure recurred after the repair. Reported from roughly 27,000 to 115,000 miles, often during normal driving without warning.

   Recall 06V1990001 related service bulletin

   What to check: Inspect the plastic fan blades for cracks or missing tips and check the shroud and radiator for damage; ask whether the fan assembly was replaced and whether the fan recall was completed for this VIN.

   “I own a 2002 Jeep Grand Cherokee. About a week ago while driving I heard a loud pop come from the engine. When I stopped to examine the problem, I saw a large leak coming from the bottom of my car. After looking under the hood, I saw that the plastic cooling fan in my engine had shattered and the pieces punctured my radiator. The shroud covering my cooling fan had also been shattered. I immediately took the Jeep to my local chrysler dealer (whom I bought the car from). …”

   NHTSA complaint #10137521, filed 2005-09, 65,271 miles

   “When I put my car in drive, there was a loud bang - sounded like the car was shot, so I pulled over. Coolant was leaking out and there were pieces of black plastic all over the ground. When I lifted the hood, I found that only half my fan was attached. The other half apparently broke off and blew threw my radiator. I had to replace the fan, motor, radiator, the fan shroud and coolant. The garage said they had never seen anything like it. This was an expensive repair with no warning signs. The car is pampered and maintained well.”

   Engine cooling

   Engine misfire, rough running and stalling

   • 64 complaints (4%)
   • median 64,000 mi at 4.9 yrs old (45 state mileage)
   • 4 mention a crash, fire or injury
   • owner-quoted repair $850 (median of 5 quotes)
   • filed 2002–2024

   Complaints describe rough idle after refueling, smoke, and valvetrain damage such as a rocker arm pushed through the valve cover. Others report the engine failing to start with the check engine light on, or the vehicle hesitating and then lurching when the accelerator is pressed, with a catalytic converter replacement suggested in one case without resolving it. One complaint describes a ticking noise attributed by the dealer to the purge solenoid. Reported from very low mileage up to about 200,000 miles, often during normal driving or shortly after refueling.

   Recall 02V1040002 related service bulletins

   What to check: Listen for ticking or rough idle on a cold and warm start, check for smoke at the tailpipe, and scan stored engine codes; ask about any history of ignition, valve cover or intake manifold work.

   “We were driving Jeep on highway and all was normal. We stopped for fuel and when we started the car it idled very rough and started smoking. Shut car off and upon inspection the rocker arm had been pushed through the valve cover. Appears to be damage to valve but do not know extent of damage yet. Engine had approx. 108,000 miles on it.”

   NHTSA complaint #10462917, filed 2012-06, 108,000 miles

   “Engine light keeps coming on. Dealer, car max, stated it was a chip which cost $350 to repair. They stated it was not life threatening and will not repair it at their cost. I need to know when the light came on if the engine was in trouble or not, and I felt it should be repaired at their expense.”

   Seats

   Heated seat element overheats

   • 87 complaints (6%)
   • median 97,205 mi at 8.2 yrs old (76 state mileage)
   • 16 mention a crash, fire or injury
   • owner-quoted repair $750 (median of 8 quotes)
   • filed 2002–2019

   Owners report the driver-side heated seat becoming uncomfortably hot, in some cases burning or marking the occupant's legs, and they stop using the heater. Complaints say the dealer quoted a replacement seat heater assembly and that the vehicle was not covered by the heated seat recall. Other seat complaints describe the seat track or seat back giving way, which is a separate concern from the heater. Reported from about 60,000 to 130,000 miles, whenever the seat heater is in use.

   Recall 09V117000

   What to check: Test the heated seats on both settings and stop if either gets excessively hot; ask whether the seat heater elements were replaced under the recall or a prior service, and check the seat track for wobble.

   NHTSA complaint #10523783, filed 2013-07, 100,000 miles

   “The heated seat on my 2002 Jeep Grand Cherokee overland overheated and burned my legs. I now leave the heated seat turned off. I took the car to the Jeep dealer and they stated it needs a new seat heater assembly and will cost $800.00. I cannot afford to pay that much so I did not have it replaced. I saw a recall notice on the NHTSA web site and discussed this with the Jeep dealer. The Jeep dealer stated that my Jeep is not covered in the recall.”

Buying note. A 2002 Grand Cherokee can be a workable older SUV, but confirm in writing that the air bag control module recalls were completed and that the climate system heats and defrosts on both sides before you buy. Have a mechanic check the cooling fan and radiator, the heated seats, and pull engine codes, since these are the repairs owners most often describe paying for.
