New Car Assessment Program

The 2011KIAOPTIMA carries 766 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 38 crashes, 46 fires, 29 injuries, and 2 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 5/5 rating, with 5/5 front crash, 5/5 side crash, and 5/5 rollover scores derived from standardized barrier and dynamic tests.

Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2011 OPTIMA is engine with 251 filings, followed by steering (99) and exterior lighting (81). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 5 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.

NHTSA currently has 38 investigation files overlapping the 2011 OPTIMA, and 1 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

While driving the Kia on the highway (in the passing lane on Route 93, Boston, MA), the hood of the car flew open and shattered the windshield. Prior to getting into the vehicle, there was no notification, warning light/display, that alerted to the hood or anything else not being 'closed', no rattling of the hood either. The hood blocked my entire vision with the exception of a small area below, where I miraculous got over to the breakdown lane without causing any accident. When I got out of the car, the hood was bent and the second latch was loose. It did not hold its shape. Called the police and the insurance company, the car was deemed a total loss. This incident occurred on January 31, 2026 at 10:05AM. The conditions were dry and sunny. The state trooper said that this incident could have had serious safety consequences to the driver and others since no one expects a hood to fly open, block visibility...this highway is a busy road and could have impacted several other vehic

I was driving in the highway doing about 80mph passing a semi truck when all of a sudden my vehicle went from 80 down to 50 mph and I was jerked forward. I thought I was rear ended but when I looked in my rear view mirror no cars were behind me. I looked down and noticed my engine light, battery light and oil light were on and turned down my music and could hear my engine was no longer running. Thankfully there wasn't much traffic and I was able to coast to the side of the highway and turn the car off. If someone would have been behind me I am confident I would have been hit. The problem has since been confirmed by a dealership and info has been sent to Kia. The dealership was unable to provide me with a loaner car as "they had none available" so I contacted Kia corporate and they are telling me my only option is that I have to come out of pocket for a rental and they will reimburse 40$ per day. I don't think especially since I had to pay for 2 nights in a hotel as I was stranded, a fe

After getting HECU recall done , it has caused issues with the HECU module to where the brake lights no longer work and the ESC light comes on the cluster panel. Up on reading the code C2130, it says Brake lamp relay error. Mind you that my car was in working order before this recall was even done. This a huge safety issue not having your brake lights work. I can get rear-ended and i have kids in the car. This has been a issue since July when i got the recall done and KIA has yet to find a fix for this matter.
