A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

NHTSA investigations into the 2007 Hyundai Sonata

An investigation is the step before a recall: the agency has seen enough complaints to look into a pattern itself. An open one means it thinks something may be wrong and nothing has been fixed yet.

Recalls on the 2007 Hyundai Sonata

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

13V354000

SUSPENSION:REAR

Hyundai is recalling certain model year 2006-2010 Sonata vehicles manufactured March 1, 2005, through January 21, 2010; and model year 2006-2011 Azera vehicles manufactured September 27, 2005, through November 22, 2010 originally sold in, or currently registered in, Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin and the District of Columbia. Road salt and water can enter portions of the rear crossmember, leading to corrosion of the crossmember steel. This may lead to detachment of one of the rear control arms.

Risk: Control arm separation may suddenly change the rear wheel alignment, affecting the handling of the vehicle, increasing the risk of a crash.

13V113000

EXTERIOR LIGHTING:BRAKE LIGHTS:SWITCH

Hyundai Motor Company (Hyundai) is recalling certain model year 2006-2009 Accent, model year 2007-2011 Azera, Sonata and Sante Fe,2006-2011 Tucson, 2009-2011 Elantra Touring, 2007-2010 Elantra, 2008-2011 Veracruz, 2009-2011 Genesis, 2010-2011 Genesis Coupe, 2007-2008 Entourage, and 2006-2008 Tiburon vehicles. Originally, in April 2013, Hyundai recalled 1,059,824 model year 2007-2009 Accent and Tucson, model year 2007-2010 Elantra, model year 2007-2011 Santa Fe, model year 2008-2009 Veracruz, model year 2010-2011 Genesis Coupe, and model year 2011 Sonata vehicles. In September 2013, Hyundai informed the agency that it was adding more vehicles to this campaign, representing an additional 652,512 units. The total number of vehicles being recalled is now 1,712,336. In the affected vehicles, the stop lamp switch may malfunction. A malfunctioning stop lamp switch may cause the brake lights to not illuminate when the brake pedal is depressed or may cause an inability to deactivate the cruise control by depressing the brake pedal. Additionally, a malfunctioning stop lamp switch may also result in intermittent operation of the push-button start feature, affect the operation of the brake tra

Risk: Failure to illuminate the stop lamps during braking or inability to disengage the cruise control could increase the risk of a crash. Additionally, when the ignition is in the 'ON' position, the transmission shifter may be able to be moved out of Park without first applying the brake. This may lead to unintentional movement of the car which may increase the risk of a crash.

EXTERIOR LIGHTING

HYUNDAI IS RECALLING 3,011 MODEL YEAR 2005-2007 ELANTRA, TUCSON, SONATA, AZERA AND ACCENT VEHICLES. A MALFUNCTIONING STOP LAMP SWITCH MAY CAUSE THE BRAKE LIGHTS TO FAIL TO ILLUMINATE WHEN THE BRAKE PEDAL IS DEPRESSED OR MAY CAUSE THE BRAKE LIGHTS TO REMAIN ILLUMINATED WHEN THE BRAKE PEDAL IS RELEASED. A DEFECTIVE STOP LAMP SWITCH MAY ALSO AFFECT THE OPERATION OF THE BRAKE-TRANSMISSION SHIFT INTERLOCK FEATURE SO THE TRANSMISSION WOULD NOT BE ABLE TO BE SHIFT OUT OF THE "PARK" POSITION. IT MAY ALSO CAUSE THE ELECTRONIC STABILITY CONTROL (ESC) MALFUNCTION LIGHT TO ILLUMINATE, AND IT MAY NOT DEACTIVATE THE CRUISE CONTROL WHEN THE BRAKE PEDAL IS DEPRESSED.

Risk: ANY OF THESE MALFUNCTIONS COULD LEAD TO A CRASH.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2013325 110,104 units in Canada

Electrical

On certain vehicles, the stop lamp switch may fail and cause intermittent operation of the brake lights. Failure of the brake lights to illuminate when the brake pedal is depressed could result in a crash causing property damage and/or personal injury. Correction: Dealers will replace the switch.

Recall 2013280 52,317 units in Canada

Structure

On certain vehicles, road salt can corrode the rear crossmember assembly, which may ultimately lead to separation of the control arm at the mounting point. This would allow the wheel to rotate off its designed axis, and could result in a loss of vehicle control and a crash causing property damage and/or personal injury. Correction: Dealers will repair or replace the rear crossmember assembly.

Recall 2009120 67,976 units in Canada

Lights And Instruments

On certain vehicles, the stop lamp switch may have been incorrectly installed during vehicle assembly. This could prevent proper brake lamp operation. Failure of the brake lamps to illuminate when the brakes are applied may result in the following road users being unaware of the driver's intentions, increasing the risk of a crash causing injury or death. A malfunction of the switch may also cause the brake lamps to remain illuminated when the brake pedal is released. Additionally, a faulty switch may affect the operation of the brake-transmission shift interlock on automatic transmission-equipped vehicles so that the transmission shifter would not be able to be shifted out of PARK position. It may also cause the Electronic Stability Control (ESC) light to illuminate, and it may not deactivate the cruise control when the brake pedal is depressed. Correction: Dealers will replace the stop lamp switch assembly.

Recall 2008140 31,542 units in Canada

Airbag

On certain vehicles equipped with an advanced airbag system, the Occupant Classification System (OCS), installed in the right front seat of the vehicle, may misclassify a small stature adult as a child and deactivate the passenger airbag. This would cause the right front airbag to not inflate in a crash that merits airbag deployment, and may result in injury to the right front seat occupant. Correction: Dealers will verify that the OCS does not recognize a properly seated adult occupant. After verification, the right front seat cushion assembly will be removed and reprogrammed.

ELECTRICAL SYSTEM

I have a 2007 Hyundai Sonata SE v6 3.3L and on January 9th, 2026 I had an incident where on the road my charging system light on signifying alternator failure. I made it home, but the battery was dead which was recently purchased. After recharging the battery I conducted tests with a multimeter and have determined the alternator has failed. The alternator has accrued a coating of oil overtime that was unknown until my research into the matter of root cause. Hyundai manufactures a V6 engine family called Lamba in which a version called Lambda MPi G6DB was introduced in 2007–2009 Hyundai Santa Fe (CM) and 2005–2009 Hyundai Sonata (NF) models. In 2023 Hyundai issued a recall for the 2007-2009 Santa Fe for a Cylinder Head Cover Oil Leak Repair where oil drips from the valve cover directly onto the alternator causing it to fail. I have a 2007 Hyundai Sonata 3.3L V6 engine where the very same issue has occurred with photo evidence that has caused my alternator to fail and have tested the issue. This vehicle model was not included in the recall despite the engine being exactly the same as the recalled model, the year being the exact same as the Santa Fe, and the alternator in the exact placement where the oil drips into the alternator causing failure just like the Santa Fe recall. The Santa Fe recall with the same issue is documented with National Highway Traffic Safety Administration below: [XXX] Hyundai has yet to issue the same recall for the Hyundai Sonata brand of vehicles, despite the same issue occurring and a known issue with the Lambda MPi G6DB engine design effecting multiple models in the same way documented across multiple owners of these vehicles with various fixes suggested on Youtube, Reddit, and enthusiast forums for this engineering failure that causes considerable risk if the alternator fails in operation on roadways.

Red “airbag” light on dash illuminated while driving. Code read as B1706: passenger buckle pretensioner. May have been covered under Hyundai’s 15yr/250k warranty but owners never notified since not official recall. Although, this defect may not affect airbags themselves it causes “airbag” light to remain illuminated until addressed. Driving with the “airbag” light continuously illuminated may pose risk to unsafe conditions due to unknown new airbag codes since “airbag” light already illuminated with buckle pretensioner code B1706.
