NHTSA investigations into the 2010 KIA Optima

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.

Loss of Motive Power

The National Highway Traffic Safety Administration (NHTSA) received a letter dated July 13, 2022, petitioning the Agency to initiate a safety defect investigation into loss of motive power allegations attributed to oil drain pan assembly failures on certain Hyundai Motor America, Inc. and Kia America, Inc. vehicles spanning Model Years (MY) 2005-2021. The Petitioners cited examples of complaints indicating that the subject vehicles were experiencing rapid loss of engine oil due to oil drain plug back outs, resulting in loss of motive power and/or catastrophic engine damage.

The Office of Defects Investigation (ODI) of the National Highway Traffic Safety Administration (NHTSA) received a petition letter dated October 10, 2021, requesting an investigation of possible defects in the electronic throttle control (ETC) system on certain Kia vehicles resulting in the opening of DP21-003. Accordingly, Model Year (MY) 2005-2016 Kia Optima/K5, MY 2006-2015 Kia Sorento, MY 2007-2016 Hyundai Elantra, MY 2007-2016 Hyundai Santa Fe, MY 2006-2015 Hyundai Sonatas are all part of the subject population.

Recalls on the 2010 KIA Optima

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.

EXTERIOR LIGHTING:BRAKE LIGHTS:SWITCH

Kia Motors Corporation (Kia) is recalling certain model year 2007-2010 Rondo, model year 2007-2011 Sedona, Sorento and Sportage, model year 2010-2011 Soul, model year 2008-2011 Optima, model year 2010 Forte, model year 2007-2009 Amanti, and model year 2009 Borrego vehicles. Originally, in April 2013, Kia recalled 623,658 model year 2007-2010 Rondo and Sportage, model year 2007-2011 Sorento, model year 2007 Sedona, model year 2010-2011 Soul, and model year 2011 Optima vehicles. In September 2013, Kia informed the agency that it was adding an additional 356,719 vehicles to this campaign. The total number of vehicles being recalled is now 980,377. 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-transmission shift interlock feature preventing the shifter from being moved out of the PARK position and cause the Electr

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.

Recalls cover specific build ranges, so check your own vehicle by VIN at nhtsa.gov/recalls or, in Canada, Transport Canada.

Merced, CA

ENGINE

The engine on my 2010 Kia Optima suddenly seized without warning around 150,000 miles. The vehicle had no knocking sounds or warning signs prior to failure. A mechanic diagnosed the vehicle with a seized engine. This created a sudden loss of vehicle operation. I am concerned this may be related to the known engine failure issues reported in Kia vehicles.

Car would not engage into “Park” while attempting to park car in driveway. Shifter would not engage in any gear. Tried to reset button in center console. Contacted mechanic, he towed to garage. Plastic clip connected to cable broke. Earlier Kia’s had a recall due to this issue, why not all Kias due to it is still happening. I was very fortunate that this happened to me in my driveway and not on the highway. I understand there is the same part at the other end of the cable, connects to transmission and shifter, if it also breaks it is going to be very expensive to repair due to placement of the part. I had to rent a vehicle for work while part had to be ordered and replaced.

ENGINE

Rod bearing knocking noise. Vehicle stopped running when slowing down. Car is available for inspection. No warning lights come on. The rod bearing can pierce the engine and cause oil to leak and then a fire. Problem first identified by Monroe and then another independent when the car died in front of his shop- both confirmed this is a known issue with kias- but since ours is a 2010 it is not covered under the current recall for the same issue in years 2011 to 2013. I spoke with cooper Kia in Utica as I was looking for support with this issue and was told by Mike Digiovanni to call a lawyer. On a later call to Pat Stacey he said they don’t work for Kia and he stated that the salesman said I came in threatening to call a lawyer- not true- I was advised to call one. I had gone in explaining that I was upset as I thought this was a safe car for my 17 year old to travel in between college and work and it’s the same issue as the 2011-2013 recall
