2003 Hyundai Sonata Problems

What owners report

Owners of this model year most often write about the airbag warning light staying on and, less often, about airbags that did not deploy in a crash. Peeling chrome on the interior door handles that leaves a sharp edge is the second recurring theme, and rust on the front subframe shows up repeatedly on cars kept in states that use road salt. Trouble filling the fuel tank and electrical gremlins round out the picture, with most reports arriving between roughly 50,000 and 130,000 miles.

   Air bags

   Airbag warning light stays on

   • 25 complaints (13%)
   • median 55,000 mi at 7.2 yrs old (23 state mileage)
   • filed 2006–2019

   Owners describe the airbag warning light coming on and staying on, usually with no crash history and no visible damage to the seats or wiring. Dealers read a code for high resistance in the side airbag circuit and quoted replacement of the airbag wiring harness; others replaced a circuit board or the passenger airbag, and in several cases the light returned within weeks. Owners often note that the work was not covered once the car was outside its warranty. Reported from about 14,000 to over 120,000 miles, with most complaints falling between roughly 50,000 and 95,000 miles.

   What to check: Turn the key to the run position and confirm the airbag light goes out after the self-check, then watch it over a test drive. Ask whether the harness or clockspring has been replaced and whether any diagnostic codes were stored.

   “I am the one-owner of a 2003 Hyundai Sonata, 4 cyl., sedan. Two months after my warranty expired, the airbag light came on. I have yet to have it checked, but the vehicle has never been in an accident. I am hesitant to find out how much this indicator will cost to diagnose.”

   NHTSA complaint #10243346, filed 2008-09, 54,000 miles

   “For no specific reason my 2003 Hyundai Sonata 4 cylinder base model's airbag light came on. I had to get the passenger airbag replaced at a cost of $900 at the dealer. No explanation was given by the dealer as to why the bag went bad.”

   Latches, locks and linkages

   Sharp edges on interior door handle chrome

   • 26 complaints (13%)
   • median 80,403 mi at 8.8 yrs old (20 state mileage)
   • 14 mention a crash, fire or injury
   • filed 2006–2016

   Owners report the chrome plating on the interior door handles cracking, lifting, or peeling and leaving a sharp edge that has cut the fingers and hands of drivers and passengers, including children in the back seat. Some say the dealer replaced the handles under a recall and the replacement parts peeled again, while others were told their vehicle was not included in the campaign even though the handles looked the same. Several owners taped over the handles in the meantime. Reported from roughly 30,000 to over 150,000 miles, most often between about 55,000 and 130,000 miles.

   Recall 09V317000Recall 09V171000

   What to check: Run a finger along the top edge of each of the four interior door handles and look for lifting or split plating. Ask whether the handle campaign was completed and whether the handles have been replaced since.

   “Two of the inside door handles have a silver metallic foil that has split and come loose. My son cut his finger opening the door. Now the driver door inside handle also has the silver foil coming loose. We have had to put tape on it to prevent getting another cut finger.”

   NHTSA complaint #10238732, filed 2008-08, 55,000 miles

   “The interior door handles of my 2003 Hyundai Sonata went under a recall in july 2009 because the chrome plating was splitting open and cutting people. Three door handles were replaced and one was rewrapped to fix the problem. In september 2013 the same issue arose when my wife and brother-in-law cut their hands on the door handles, whose chrome plating has again begun to split. Hyundai has said that no repairs will be made, since the handles were treated and the 2009 recall has finished.”

   Body and structure

   Front subframe corrosion (rust-through)

   • 22 complaints (11%)
   • median 108,500 mi at 12.2 yrs old (16 state mileage)
   • filed 2008–2026

   Complaints describe rust developing on the front subframe and engine cradle, in some cases severe enough that the metal thins or perforates and the mounting area for the lower control arm is affected. Owners mention noises, tire misalignment and steering pull, and one report describes a rear upper control arm and frame found heavily corroded during strut replacement. Several owners link their experience to a suspension rust recall but were told their vehicle was not included, and some were told the recall repair could not be carried out because of how far the corrosion had progressed. Typically reported between about 60,000 and 180,000 miles on cars kept in states that use road salt, though a few appear below 70,000 miles.

   Recall 09V124000

   What to check: Have the car put on a lift and inspect the front subframe and control-arm mounting points for flaking metal or holes, especially if it has been registered in a salt-belt state. Ask whether the suspension rust campaign was ever performed.

   “I took my 2003 Hyundai Sonata in for a routine inspection and found out that the engine cradle had rusted through and was no longer drivable. The engine cradle had to be replaced, which is no small feat on this vehicle. I have read several other complaints of this and know it's under investigation, but wanted to log my complaint as well.”

   NHTSA complaint #10236807, filed 2008-08, 68,500 miles

   “Nhtsa action # ea08016 my 2003 Sonata which was purchased in ny operated there until 06/2008 was not recalled under the above action #. I feel this is a mistake as this car is showing symptoms described in the recall # 09v124000. I called Hyundai america with negative results.”

   Air bags

   Airbags not deploying in a crash

   • 17 complaints (9%)
   • median 88,647 mi at 8.8 yrs old (12 state mileage)
   • 13 mention a crash, fire or injury
   • filed 2004–2019

   Owners describe frontal and side impacts in which none of the airbags deployed, including a guard-rail head-on impact and a rear-end collision at about 45 mph. Some of these reports note that the airbag warning light had been coming on beforehand, while others say the system had shown no prior sign of trouble. A few owners say the manufacturer reviewed the crash and concluded the sensors had worked as designed. Described in crashes at mileages from roughly 38,000 to 107,000.

   What to check: Check that the airbag light proves out and then goes off, and ask for any history of airbag or sensor repairs. A pre-purchase inspection that pulls stored airbag codes is worth the cost on this generation.

   “In 2005 while driving my girl friends 2003 Hyundai Sonata, I went to make a left turn of a main street in oakland, ca. And was hit by a 2006 mercedes benz own the passenger side. No air bags where deployed at all. $8.000 dollars in damage was done. Hyundai corporation never came out to look at the car, but ruled that the sensors acted properly. The car wa equipped I believe with front and side air bags.”

   NHTSA complaint #10149454, filed 2006-02, 46,800 miles

   “Two days after my grandmother purchased a 2003 Hyundai Sonata, she was involved in a minor accident. The car was traveling at 45 MPH when it rear ended another vehicle. The airbag never deployed and as a result, she broke her breast bone and as of today, is still hospitalized from the accident.”

   Fuel system

   Fuel filler backs up and spills while refueling

   • 13 complaints (7%)
   • median 143,000 mi at 10.2 yrs old (10 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2004–2020

   Owners report the tank will not accept fuel normally: the pump nozzle clicks off repeatedly, gasoline backs up or spills out of the filler neck, and filling the tank can take many minutes. Some describe a strong fuel smell in or around the car, and a few connect the problem to tank valve or canister work that did not resolve it. Dealers quoted several hundred dollars for the repair, and one owner reported the fuel tank being damaged during that service. Mostly reported above 90,000 miles, with several owners past 140,000 miles.

   Recall 04V369000Recall 04V178000

   What to check: Try a full fill-up during the test drive and note whether the nozzle keeps shutting off or fuel spits back. Ask whether the tank valve or canister was replaced and whether any fuel smell has been investigated.

   “I was having great difficulty getting fuel into the vehicle. I took it to the Hyundai dealership in annapolis, md. They replaced the valve-canister cl, canister assy., and valve-purge contr. When I picked up the vehicle, the issue had not been resolved. I took it back and I'm not sure what other parts they may have replaced because I never again received any paper work. When I picked it up again, I was able to put gas in it, but it was leaking fuel all over the road afterwards. They had punctured a hole in my gas tank while working on it. …”

   NHTSA complaint #10629368, filed 2014-08, 138,000 miles

   “I was informed this model has a safety valve in the gas filler neck that will prevent the gas from leaking out should the vehicle overturn. My valve must be stuck in the partially open position since I can only fill the gas tank every one-third of a gallon before the gas dispenser shuts off. Then I have to wait 10 seconds for it to seep into the tank before I can continue to pump. Filling my 17 gal tank takes about 10-12 minutes with most of the time just waiting for the gas to seep into the tank. Hyundai wants over $600 to repair. Unacceptable since it appears to be a design flaw.”

   NHTSA complaint #10546258, filed 2013-09, 148,000 miles

Buying note. Ask for the recall history on the door handles, fuel tank valve and suspension, and confirm the airbag warning light behaves correctly on a test drive. Given the age of these cars, a lift inspection of the subframe for rust is the single most useful pre-purchase step, particularly if the car has spent its life in a state that salts its roads.
