2007 Kia Optima Problems

What owners report

Owners of this model year most often describe two long-running frustrations: a passenger airbag indicator that stays on with an adult in the seat, and sun visors that lose tension and hang down in the driver's line of sight. A smaller but consistent group describes low-beam headlights too dim to light the road, with many having replaced bulbs and assemblies without lasting improvement. Reports arrive across a wide mileage span, from near-new cars to well past 100,000 miles.

1. 1
   Air bags

   Passenger airbag "off" light with an adult seated

   • 56 complaints (34%)
   • median 67,000 mi at 5.5 yrs old (41 state mileage)
   • 2 mention a crash, fire or injury
   • owner-quoted repair $1,600 (median of 9 quotes)
   • filed 2007–2026

   Owners describe the passenger airbag indicator staying lit, or reading off, while an adult is properly seated, sometimes intermittently and sometimes most of the time. Several say the dealer checked the system and found it within specification, advised on how passengers should sit or what weight the seat needs, or reset the indicator only for it to come back shortly after. Others report the airbag warning light coming on steadily and being told the passenger seat sensor mat needed replacement. Reported from very low mileage up to about 105,000 miles, in many cases within the first year of ownership.

   Recall 12V0140005 related service bulletins

   What to check: With the engine running, sit in the front passenger seat and confirm the indicator shows the airbag as active; ask whether the occupant classification sensor mat was replaced under the extended warranty coverage described in the service bulletins.

   2 excerpts from owner complaints in NHTSA records

   “In 2007 I purchased a new Kia Optima from coleman Kia in trenton, nj. Soon after, I discovered that the passenger airbag indicator light would sometimes remain illuminated even though there was an adult passenger in the seat, meaning that the airbag was not activated. The dealer performed a system check and determined that the system was performing to specifications. Shortly thereafter, the problem recurred. …”

   NHTSA complaint #10279816, filed 2009-08, 6,750 miles

   “I was driving to work and my drivers side airbag came on. A few months prior, we had to replace the o2 sensor because the check engine light was on. Now on the second day with the airbag light on, the check engine light came back on! Is it bad wiring, will my airbag not work?”

   Visibility (wipers, defrost, mirrors)

   Sun visors will not stay up

   • 30 complaints (18%)
   • median 62,000 mi at 6.0 yrs old (25 state mileage)
   • filed 2010–2019

   Owners describe one or both sun visors losing their tension or breaking internally, so they droop into the driver's line of sight or flop down while driving. Some hold the visor up by hand or with tape. Complaints say dealers quoted replacement costs and that the repair was not covered once the vehicle was out of warranty, with the visors recurring as the fix in most cases. Mostly reported between roughly 30,000 and 85,000 miles, with some at higher mileage.

   What to check: Fold each visor up and let go; it should stay against the headliner without sagging. Check the pivot and the clip on both sides.

   2 excerpts from owner complaints in NHTSA records

   “Driver side sun visor broke and will not stay in the stored position, therefore it hangs in my view when driving. I have tried to secure with velco for the time being, but it does not hold. The passanger sun visor has also broke and will not stay in the stored position and therefore blocks my view at stop signs and while looking in the passanger mirror when changing lanes”

   NHTSA complaint #10416208, filed 2011-07, 84,250 miles

   “Driver side visor ceased to remain upright when flipped up out of the way. Only way to keep from blocking my view was to flip it over to the left side. A few months later, same thing happened with the passenger side sun visor. Kia never recalled this item, but it has failed on thousands of their vehicles. Dealer wanted over $500 to repair. Instead, I searched online and found new replacement parts for $206.50. …”

   Exterior lighting

   Low-beam headlights too dim to see the road

   • 26 complaints (16%)
   • median 114,500 mi at 7.9 yrs old (18 state mileage)
   • filed 2010–2024

   Owners describe low beams that give very little light at night, forcing them to drive on high beams, and repeated bulb or headlight assembly replacements that did not restore usable low-beam output. Some report that dealers checked the circuits or replaced bulbs without resolving it; one independent mechanic recommended replacing the headlight assembly. Frequent bulb failures on either side are also mentioned. Often described from around 45,000 miles upward, and most commonly on higher-mileage vehicles past 90,000 miles.

   What to check: Check low-beam brightness at night on a dark road, and ask whether the headlight assemblies or bulbs have already been replaced; a TSB covers moisture and condensation inside the lamp housings.

   2 excerpts from owner complaints in NHTSA records

   “Low beam headlights, keep replacing bulbs, exact bulbs required by Kia. Alternating either the driver's side or the passenger. Beside this problem, the headlights are so low that at night I have been running with high beams on for over a year now; on-coming cars don't seem to be bothered by the high beams. Usually high beams cause on coming vehicles to flash their high beams, but this is not the case, we've discussed with firestone, they tested the bulbs and believe it is electrical. …”

   NHTSA complaint #10701885, filed 2015-03, 250,000 miles

   “Frequent low beam and high beam headlight failures over last 4 years..last month I had to replace the whole passenger side headlight assembly..my left headlight assembly is currently out on the low settings..”

   Electrical system

   Vehicle will not start or shift out of park

   • 21 complaints (13%)
   • median 60,500 mi at 3.9 yrs old (16 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2009–2025

   Owners describe the ignition key failing to turn, at times with the steering wheel locked, and being told the wheels must be left straight when parked or the car will not start. Others report being unable to move the selector into drive or reverse, and a case where the car rolled after being left in park; one owner said the dealer stated the VIN was not covered under the recall for the shift cable. Reported from a few thousand miles up to about 82,000 miles.

   Recall 11V1530002 related service bulletins

   What to check: Check that the key turns freely and the wheel unlocks, and test selecting drive and reverse repeatedly; ask whether the shift cable recall work was performed on this vehicle.

   2 excerpts from owner complaints in NHTSA records

   “On two occasions (to date) my Kia Optima has become inoperable - unable to put the car in drive or reverse. The first occurred during the winter in february 2010. After one of many snowstorms this season I was driving on a plowed road then encountered an area where there was only room enough for one car to pass. When I pulled over to allow an approaching vehicle to pass my car was in about 8-inches of snow. …”

   NHTSA complaint #10342445, filed 2010-07, 25,000 miles

   “The contact owns a 2007 Kia Optima. The contact stated that the key would not turn when placed in the ignition switch and the steering wheel unexpectedly seized. After numerous attempts, the ignition key began to turn and the steering wheel unlocked. The failure recurred intermittently. The vehicle had not been diagnosed or repaired. The manufacturer was notified of the problem. The approximate failure mileage was 82,000.”

Buying note. Inspect the passenger airbag indicator with someone seated in the front passenger seat, check both sun visors and the low beams at night, and confirm which open recalls have been completed. A pre-purchase inspection that includes engine condition is worthwhile given the reports of stalling and engine damage.
