2003 Lincoln Aviator Problems

What owners report

Owners of the 2003 Lincoln Aviator most often describe transmission trouble: rough or delayed shifting, slipping out of gear, and a shift cable that comes loose or a shifter knob/lever that breaks and leaves the vehicle stuck in one gear. A second recurring theme is cosmetic and body hardware trouble around the rear liftgate and its glass, with cracks near the Lincoln emblem. Reports are spread across the mileage range, from low-mileage early complaints to vehicles well past 100,000 miles.

1. 1
   Transmission and drivetrain

   Shift cable dislodges or shifter sticks in gear

   • 31 complaints (28%)
   • median 99,000 mi at 9.4 yrs old (28 state mileage)
   • owner-quoted repair $1,200 (median of 8 quotes)
   • filed 2005–2020

   Owners describe the transmission shift cable coming loose from its bracket, so the gear indicator no longer matches the gear the vehicle is actually in, or the shifter will not move out of Park. Some report the vehicle moving in a direction other than the one selected, and several say the fix at the dealer was cable or shifter assembly replacement, sometimes with the problem returning. Others describe a broken plastic piece inside the shifter knob or lever that locks the shifter in the current gear, with dealer quotes in the range of roughly $900 to $1,300 for the whole assembly. Complaints also note that the indicator on some vehicles was not covered by the shift cable campaign. Reported from very low mileage (under 10,000 miles) up through vehicles past 130,000 miles, with several reports in the 60,000-100,000 mile range.

   Recall 02V313000

   What to check: With the engine off, move the shifter through all positions and confirm the dash indicator matches each gear; then check that the cable is seated in its bracket under the vehicle. Ask whether the shift cable or shifter assembly has been replaced, and whether the vehicle was covered by campaign 02V313000.

   “Our 2003 Lincoln Aviator continues to experience the same problem - once in park, you cannot move the gear shift to any other gear - it's stuck. Occasionally, my husband can wiggle a wire underneath the brake and gas pedals so we can shift into reverse or drive but this continues to happen. I have been stuck, alone and with our small children. Is there a permanent correction for this issue?”

   NHTSA complaint #10549749, filed 2013-10, 120,000 miles

   “I was backing out of my driveway into the street. Once I was in the street, I put the car into drive and stepped on the gas. The car went the opposite direction- reverse. I double checked the gear shift ( in the center of the vehicle), it was d for drive. I made sure it was in the d, and stepped slowly on the gas, and it went into reverse. I tried to apply the brakes, but they didn't engage. I quickly stepped on the emergency brake, and that stopped the car. …”

   Body and structure

   Rear liftgate and glass cracking near emblem

   • 11 complaints (10%)
   • median 63,052 mi at 8.7 yrs old (10 state mileage)
   • filed 2007–2017

   Owners report a crack in the rear liftgate panel near the Lincoln emblem, in some cases without any impact, and cracks along the base of the liftgate glass. Some say the liftgate or its hinges no longer hold the glass properly and that the glass can open while driving. According to the complaints, dealers often declined to cover the repair and described it as structural damage or as outside warranty. Reported from around 50,000 miles to past 100,000 miles, and often described as appearing without an event.

   What to check: Inspect the liftgate panel on both sides of the emblem and the bottom edge of the liftgate glass for hairline cracks, and open and close the glass to confirm the latches hold. Ask whether the liftgate or glass has been replaced.

   “The back lift component has a crack on each side of the Lincoln emblem. The body shop near where I work told me that this is very common with the aviators, and that he has replaced many of them. It is a manufacturing error and should be replaced by ford/Lincoln. I have purposely looked at other aviators and found that they have the same cracks in the same place by the emblem. I was told by the ford dealership here that the company would not fix it. My vehicle is no longer in warranty. …”

   NHTSA complaint #10260953, filed 2009-03, 50,000 miles

   “Shifter knob on 03 Aviator broke off. The shifter was locked in drive, had to shut off vehicle and brace the tires from rolling on an incline. With my child in the car with me. Scary!!!!!! The problem is a plastic piece broke in the shifter column. Has yet to be fixed. Quoted $900 to fix. Also the liftgate cracked at the Lincoln emblem witch I was told that it holds the glass in place and it sound like a gunshot when it cracked, shook me up. This is a ford/Lincoln failure on a manufacturer defect. …”

   Transmission and drivetrain

   Transmission slips, hesitates or shifts harshly

   • 18 complaints (16%)
   • median 66,000 mi at 7.3 yrs old (17 state mileage)
   • filed 2005–2017

   Complaints describe the transmission slipping out of gear at steady speed or when accelerating from a stop, with engine rpm rising while the vehicle does not move, then engaging abruptly. Owners also report slow or harsh shifts between gears, warning lights for transmission and overdrive coming on, and difficulty getting the vehicle to move at all. Several say dealers could not duplicate or resolve the problem, and some mention internal ratio and solenoid diagnosis with repair estimates in the thousands of dollars. Reported across a wide range, from under 20,000 miles to over 150,000 miles, with many reports around 45,000-100,000 miles.

   3 related service bulletins

   What to check: Test drive from a cold start, including a stop-and-go acceleration and a highway merge, and note any delay, flare in rpm or harsh engagement. Ask for transmission service records and whether the powertrain control module has been reprogrammed.

   “I own a 2003 Lincoln Aviator, still under warranty. Since around november of 2004 I have been having transmission problems. The problem is the transmission will slip out of gear while driving at a steady speed, accelerating from a stop or slowing down and then accelerating. This is very hazardous when trying to merge onto a highway or turn into traffic and the vehicle will not accelerate. The problem exists in all gears, however, it does not do it all the time. It has continued to get worse. …”

   NHTSA complaint #10121909, filed 2005-05, 35,000 miles

   “My Aviator was shifting rough for less than 24 hours when the transfer case went out. Luckily, I had only pulled out of my driveway when it happened. The vehicle made an awful whinning and screeching noise and became impossible to drive forward. I was able to wrestle it into reverse to get it in my driveway. I live on a busy country road, this could have been dangerous for me and my 3 kids. I had it towed to the dealer and they quoted me near $1000 with no promise that the problem could be fixed. …”

   Engine cooling

   Engine misfire and ignition coil failures

   • 10 complaints (9%)
   • median 69,500 mi at 4.7 yrs old (10 state mileage)
   • filed 2006–2012

   Owners describe hesitation on acceleration, rough idle, shaking and a flashing or steady check engine light, with dealers identifying failed ignition coils on individual cylinders. Some report the same coil failure returning shortly after replacement, and others describe cylinder head or valve damage found after repeated misfires. Complaints also mention spark plug replacement as a first attempted fix. Mostly reported between roughly 55,000 and 95,000 miles.

   3 related service bulletins

   What to check: Scan for stored misfire codes and ask whether coils and plugs have been replaced and how recently. On a test drive, watch for hesitation or shaking under acceleration, and ask for a compression check if misfire codes have been present.

   NHTSA complaint #10343493, filed 2010-07, 82,000 miles

   “My 2003 Lincoln Aviator had a rough idle and was a little sluggish. With only 92,000 miles on a $45,000 car, this surprised me. This is a high performance engine. Upon accelerating to enter I-20 the vehicle almost died. Luckily ,there were no vehicles coming - had this been during rush hour it might not have been so lucky. I took the vehicle to city garage to have it checked out, and was told it had a major engine problem. The #8 cylinder had on 70 lbs of pressure, and the vehicle needed a valve job. …”

   Airbag deploys without a crash

   • 6 complaints (5%)
   • median 126,150 mi at 9.2 yrs old (6 state mileage, few)
   • 3 mention a crash, fire or injury
   • filed 2010–2015

   Complaints describe airbags deploying while the vehicle was parked or driving normally, including side curtain airbags and the driver's airbag, in some cases with the airbag light on beforehand. One owner reports the dealer attributing the deployment to a wiring issue. Others describe airbags not deploying as expected in a collision. Reported from about 60,000 miles to past 140,000 miles.

   What to check: Confirm the airbag warning light comes on at start-up and then goes out, and have any stored airbag codes read before purchase. Ask whether the airbags or related wiring have been serviced.

   “While driving down the freeway in our 2003 Lincoln Aviator, the two side curtain airbags deployed. The vehicle was brought to the nearest dealer and there was no visible damage to the front, sides, or rear of the vehicle that would explain the airbag deploying for no reason.”

   NHTSA complaint #10346735, filed 2010-08, 62,000 miles

   “The contact owns a 2003 Lincoln Aviator. The contact stated that the air bag deployed independently while the vehicle was sitting idle in park. The contact stated that the air bag struck him in the rear of the head and caused severe headaches. The manufacturer was contacted and advised the contact that their attorney would contact him at a later date. The vehicle was not repaired. The failure and current mileage was 125,000.”

Buying note. A pre-purchase inspection focused on the transmission, including a cold test drive and a check of the shift cable and shifter, is worthwhile on this model year, along with a close look at the liftgate for cracks. Service records showing transmission and ignition coil work can help set expectations for maintenance.
