2007 Hyundai Sonata Problems

What owners report

Owners of the 2007 Sonata most often report airbag warning lights, especially a passenger-seat occupant classification issue many link to a past airbag campaign, along with sun visors that drop into the driver's view and brake concerns. Reports span a wide mileage range, from very low-mileage cars to well past 150,000 miles, and several airbag complaints mention that the vehicle's VIN was not covered by the related recall.

1. 1
   Air bags

   Airbag warning light / passenger seat sensor (OCS)

   • 245 complaints (35%)
   • median 75,000 mi at 6.8 yrs old (200 state mileage)
   • 9 mention a crash, fire or injury
   • owner-quoted repair $500 (median of 38 quotes)
   • filed 2007–2026

   Owners describe the air bag warning light staying on, and in many cases a passenger airbag indicator that flashes or reads off while the seat is empty or occupied by an adult. Several say a scan showed occupant classification system (OCS) codes, or that a dealer diagnosed the passenger seat cushion or sensor assembly. Complaints frequently mention that NHTSA campaign 08V161000 was referenced but the VIN was not included, and some state dealers declined to repair or that parts were unavailable. Reported across a wide range, from cars with under 20,000 miles to ones above 170,000 miles.

   What to check: With the engine on, watch whether the air bag light stays lit and whether the passenger airbag indicator behaves correctly with an adult in the seat and again with it empty. Ask whether any airbag-related campaign work was performed and request a scan for stored SRS codes.

   2 excerpts from owner complaints in NHTSA records

   “Hyundai Sonata 2007 air bag light came on. They say it is the pretensioner in the passenger seat. I feel this is a safety issue since the air bags will not deploy with this problem. The code was b1706. It is going to cost me $500 to fix. Cannot pass inspection without it.”

   NHTSA complaint #10650676, filed 2014-10, 104,000 miles

   “Air bag warning light is on since 2013 and I believe this means in case of an unfortunate accident air bag will not kick off. Searching on google I came to know that it is a common problem.....”

2. 2
   Visibility (wipers, defrost, mirrors)

   Sun visors drop down and won't stay up

   • 129 complaints (19%)
   • median 60,000 mi at 4.5 yrs old (100 state mileage)
   • filed 2008–2019

   Owners report the driver or passenger sun visor falling out of its stowed position and hanging into the line of sight, sometimes while driving. Complaints describe the pivot or tensioner mechanism giving way, with some owners replacing a visor more than once; several mention that the dealer replaced one under warranty while others paid out of pocket for the part. Mostly reported between roughly 35,000 and 100,000 miles, with some at lower mileage.

   What to check: Fold each visor down and back up a few times and check whether it holds firmly in the stowed position without sagging; a loose or floppy pivot is the usual early sign.

   “While traveling at night on the ohio turnpike at posted speed limit, the drivers side sun visor suddenly dropped down from its normal stowed position against the headliner directly into my line of vision. This caused a brief loss of vision of the road ahead and a momentary loss of vehicle control. Sun visor would no longer stay in stowed position and had to be forcibly removed in order to safely continue my trip.”

   NHTSA complaint #10276817, filed 2009-07, 89,000 miles

   “My sunvisor on the drivers side dropped down and will not go back to the upright position. This is the third time my sunvisor has broken. One on the passenger side and twice on the drivers side. I have spent 100 dollars replacing the other side. I do not have any children in my car, it is just myself and my husband. This is ridiculous that it broke for no apparent reason. I have a 2004 Hyundai elantra and have never had problems with the visors.”

   Electronic stability control

   ESC off light comes on intermittently

   • 49 complaints (7%)
   • median 93,412 mi at 8.7 yrs old (39 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2008–2023

   Owners report the ESC off warning light illuminating at random, sometimes right after startup and sometimes while driving, and that pressing the ESC button does nothing. Some say the light clears after restarting the car; one complaint mentions the dealer recommending a hydraulic control unit replacement, and another describes the brakes locking up along with the light. Reported from around 60,000 to 150,000 miles, often during normal or wet-weather driving.

   What to check: Start the car and confirm the ESC light goes out after the self-check, then take a short drive; ask whether any ABS/ESC codes have been stored or cleared.

   2 excerpts from owner complaints in NHTSA records

   “I was just driving to work and the ESC off light came on, the only way I have been able to get it to go off is to restart the car. One of the times I had trouble getting the car in to park but after playing around with the brake pedal it final allowed me to shift. It has been happening randomly, I had it check for error codes and nothing could be found.”

   NHTSA complaint #10605750, filed 2014-06, 60,188 miles

   “I bought my car about a week ago, this morning I turned the car on and the ESC off light came on. I looked online for what the light meant and I saw that there may have been a recall on my model and year. I filled my gas tank half way and the light went off. I started it again a little bit ago and the light is back again.”

   Brakes

   Brake noise, corrosion and brake line rust

   • 77 complaints (11%)
   • median 35,000 mi at 3.5 yrs old (71 state mileage)
   • 7 mention a crash, fire or injury
   • owner-quoted repair $475 (median of 8 quotes)
   • filed 2007–2023

   Owners describe grinding from the rear brakes, corroded rotors needing replacement at relatively low mileage, and in some cases corroded brake lines leaking fluid and reducing stopping ability. Complaints mention dealers calling the wear normal, and one owner links a rear crossmember corrosion recall to rusted parts found around the brake work. Reported from about 17,000 miles up to over 160,000 miles, with several in higher-mileage, rust-prone cars.

   Recall 13V3540002 related service bulletins

   What to check: Have the brake lines and rear subframe area inspected for rust, especially on cars from salt-belt states, and ask when the rotors and pads were last replaced.

   2 excerpts from owner complaints in NHTSA records

   “My brakes failed in january, and my car hit the garage door. I spent $800 to get them fixed, only to have them fail after five months. Because of this it came to my attention that there was a rear cross member recall for corrosion on my car. To complete the recall, the dealership wants to charge me for all of the rusted parts that will break once they dig to reach the recall. …”

   NHTSA complaint #11354053, filed 2020-09, 129,802 miles

   “I want to create a safety recall on this vehicle if not other makes and models from this manufacturer. This vehicle is a fire hazard due to chronic corrosion on the fuel lines. It is also a safety hazard due to loss of brakes and steering due to chronic corrosion of the brake and power steering lines. Our 2007 Hyundai Sonata needed power steering fluid and brake fluid on a regular basis. Most recently we lost brakes and had the car inspected. …”

   Seat belts

   Airbag light tied to seat belt buckle / pretensioner codes

   • 98 complaints (14%)
   • median 91,082 mi at 7.8 yrs old (85 state mileage)
   • 5 mention a crash, fire or injury
   • owner-quoted repair $450 (median of 29 quotes)
   • filed 2008–2026

   Owners describe the air bag warning light coming on and a dealer diagnosis pointing to the front seat belt buckle or pretensioner, with codes such as B1706 or B1448. Complaints mention quoted repair costs for the buckle or SRS module, and some note that replacing the buckle did not permanently clear the light. Reported from about 60,000 to 155,000 miles, often on higher-mileage cars.

   1 related service bulletin

   What to check: Ask for any stored SRS codes to be read before purchase, and check whether the seat belts latch and retract smoothly; a persistent airbag light after a buckle replacement is worth noting.

   2 excerpts from owner complaints in NHTSA records

   “Two weeks ago my air bag light came on. Brought the vehicle into the dealer this morning and they tell me that I need a new passenger seatbelt buckle. Failure to replace this incredibly expensive part would result in the failure of the airbags to deploy in the event of a crash. Also, the state I live in would not allow the vehicle to pass inspection with this light being on. So I can not wait for a recall, I have to replace this part now. …”

   NHTSA complaint #10620656, filed 2014-08, 123,000 miles

   “Dealer found codes b1706 and b1102 present. Dealer tech stated driver seat belt buckle needs replacing, with an estimated cost of $344.56. The srs module is not allowing codes to be reset, needs replacing also, with an estimated cost of $1,004.00. I see NHTSA has just started investigating the b1706 code -- my understanding from reading the other complaints is that a short circuit is causing the error code, and replacing the seat belt assembly is not permanently fixing the problem for most owners. …”

   NHTSA complaint #10629893, filed 2014-09, 154,977 miles

Buying note. Check the airbag and ESC warning lights carefully on a test drive and ask for a scan of stored codes, since several owners report warning lights that dealers could not or would not resolve under a campaign. Also confirm whether the rear suspension corrosion recall applies to the car's registration state and inspect the brake lines for rust.
