2003 Jeep Grand Cherokee Problems

What owners report

Owners of this model year report two dominant themes: air bag warning lights and unexpected air bag deployments, and a heating/ventilation system that stops delivering hot air or defrost. Air bag complaints appear across a very wide mileage range, from around 30,000 to over 200,000 miles, while blend-door and heater complaints cluster at lower odometer readings, often within the first 50,000 miles.

1. 1
   Air bags

   Air bag warning light and unexpected deployment

   • 234 complaints (31%)
   • median 110,000 mi at 11.5 yrs old (89 state mileage)
   • 28 mention a crash, fire or injury
   • filed 2003–2026

   Complaints describe the air bag warning light coming on and staying on, and in a number of cases front or side air bags deploying with no impact, sometimes while stopped or at low speed and sometimes while driving. Several owners say the vehicle was covered by a recall but that the part was unavailable for an extended period, and some report the light returned after a module was replaced or reset. Owners also describe being told the vehicle could not be worked on until an inspection was arranged. Reported from roughly 30,000 to over 200,000 miles, with deployment reports at both low and high mileage.

   What to check: Ask whether the air bag recalls were completed and get documentation, since a warning light or an unrepaired recall comes up repeatedly in these complaints. Have the air bag system scanned for stored codes before purchase.

   “I was the only person in my vehicle at the time of the accident. I was pulling a trailer & going up a bridge at approximately 50 MPH when I lost control & hit the guardrail. My entire driver side and front end on the driver side was smashed. It bent my frame as well, however, the air bags never deployed. I called chrysler customer service # just to let them know that it happened, just so they would have a record of it. …”

   NHTSA complaint #10116559, filed 2005-04, 30,000 miles

   “While at a stop sign, both side air bags exploded with a large bang and covered all side windows of this vehicle. We were fortunate that the vehicle was stopped rather driving and possibly causing a serious injury to both my wife and myself”

   Visibility (wipers, defrost, mirrors)

   Heater blows cold, defroster stops working (blend door)

   • 176 complaints (23%)
   • median 62,000 mi at 5.1 yrs old (133 state mileage)
   • 14 mention a crash, fire or injury
   • owner-quoted repair $1,000 (median of 53 quotes)
   • filed 2003–2023

   Owners describe the heater blowing cold on one or both sides of the dash, sometimes intermittently, and a defroster that stops clearing the windshield in cold or snowy conditions. Several complaints attribute it to the blend door inside the dash and mention dealer quotes in the range of about 1,000 to 1,800 dollars for the repair. Others report the blower motor or blower resistor failing, with one owner noting melted wiring and plastic at the resistor connector. Often reported between roughly 30,000 and 110,000 miles, and most noticeable in cold weather or when defrost is needed.

   What to check: Test the heat on both sides of the dash and confirm the defroster clears the windshield; ask whether the blend doors or blower resistor have been replaced. Look at the blower resistor connector for signs of heat or melting.

   “One day I turned on the heat and cold air was blowing from one side of the dash even when I had the heat turned on. I took it to the dealer, and now I have to pay about 1000 dollars to fix it. My car only has 40000 miles Jeep Grand Cherokee 2003.”

   Seats

   Driver seat frame bracket breaks, seat rocks or detaches

   • 62 complaints (8%)
   • median 100,303 mi at 7.5 yrs old (53 state mileage)
   • 9 mention a crash, fire or injury
   • owner-quoted repair $500 (median of 5 quotes)
   • filed 2003–2020

   Owners report the front driver seat frame or bracket breaking, leaving the seat rocking side to side, leaning back, or separating from the floor mounts. Several describe welding or replacing the frame and having it break again, and some mention the heated-seat element wearing a hole in the seat cover even after recall work. Complaints say the movement is most noticeable in curves and that a used replacement frame is the usual path. Mostly reported between roughly 95,000 and 175,000 miles, on original-owner vehicles as well as later owners.

   Recall 09V117000Recall 06V197000

   What to check: Push and rock the driver seat by hand and look at the frame brackets under the seat for cracks or fresh welds. Ask whether the heated-seat recalls were performed and whether the seat frame has been repaired before.

   “We are the original owner's of our Jeep Grand Cherokee (2003) and the front driver's seat started wobbling from side to side, which makes driving disorienting particular when going around curves. When taken in to the shop we were told that the brackets attaching the seat frame have failed and are broken and need to be welded or need a replacement seat. …”

   NHTSA complaint #10482667, filed 2012-10, 145,000 miles

   “The drivers side seat has a broken bracket that allows the assembly to rock back and forth. It was perfectly fine until last week. I have owned this vehicle since 2002 and the seat was never a problem. I have found numerous complaints about seat breakage on the Jeep Grand Cherokee laredo and many other Jeep models. This is a safety issue when all attachment points break and the seat is no longer attached to the mounts.”

   Brakes

   Front brake pulsation and shaking

   • 74 complaints (10%)
   • median 24,000 mi at 2.5 yrs old (61 state mileage)
   • 10 mention a crash, fire or injury
   • owner-quoted repair $550 (median of 5 quotes)
   • filed 2003–2018

   Owners describe the steering wheel and front end shaking or pulsing when the brakes are applied, often at higher speeds and often shortly after the vehicle was new. Complaints mention rotors being resurfaced or replaced, and some say the dealer attributed it to pad heat or the owner's driving. In some cases the shaking returned after the repair. Frequently reported at low mileage, in several cases under 20,000 miles and as early as a few hundred miles.

   What to check: Brake firmly from highway speed on the test drive and feel for pulsation through the wheel. Ask when the rotors and pads were last replaced and whether the rotors were resurfaced.

   “I pulled into my driveway (which has a small incline) and put the car in park. As soon as I took my foot off of the brake the vehicle started rolling down my drive way, until pushed the brake pedal and put on the emergency brake. This has happened several times and different places, I.e work, gas station, home, school. This has not cause an accident yet since I've been in the drivers seat every time so far.”

   NHTSA complaint #10544408, filed 2013-09, 135,257 miles

   “I have made 4 trips to the service department for a problem with my brakes. The car shakes when pressure is gently applied to the brakes. The dealer has done nothing except replacing the rotors and the gear box. The problem has not been solved. Also, the car makes a loud klunking noise when the car is put into reverse or taken out of reverse. Once again, the dealer says it is normally, depsite the fact any normal person could tell something is definetly wrong with the transmission.”

   Engine cooling

   Engine stalls or shuts off while driving

   • 53 complaints (7%)
   • median 79,000 mi at 6.7 yrs old (49 state mileage)
   • 5 mention a crash, fire or injury
   • filed 2004–2020

   Owners report the engine stalling at low speed, on the highway, or while pulling away, sometimes with the check engine light on and sometimes with an electrical shutdown of the whole vehicle. Complaints mention the crankshaft position sensor being replaced, in one case with the stall returning the same day, and restarting sometimes taking several attempts. A related group describes the engine speed rising on its own while stopped with the brake applied. Reported from roughly 32,000 to 130,000 miles, at both city and highway speeds.

   “Car stalls while running. This happens mostly on low gear but also has happened while on the highway. This is a serious hazard to the extent I do not want my children in this vehicle. Do not know what to do as I see on the web many complaints of this nature.”

   NHTSA complaint #10239265, filed 2008-08, 66,000 miles

   “While stopped at a traffic light my Jeep started to accelerate and, even with the brake pedal fully depressed, surged forward. This has happened numerous times in the past week both at traffic lights and at stop signs, always while stopped. The rpms have increased to between 1,500 and 4,500. The Jeep dealer attempted to fix it on tuesday, however the problem re-occurred on my way home and again with a mechanic in the vehicle when I brought it back. To date, the car is still at the dealer and has not been fixed.”

   NHTSA complaint #10445566, filed 2012-01, 114,000 miles

Buying note. Check recall completion paperwork for the air bag and heated-seat campaigns first, since parts availability and repeat air bag warning lights are recurring themes. Then verify the heater and defroster work on both sides, rock the driver seat, and brake hard from speed on the test drive.
