The 2009HYUNDAISONATA carries 610 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 29 crashes, 16 fires, 40 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2009 SONATA is service brakes with 64 filings, followed by electrical system (57) and engine (56). 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 2 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 37 investigation files overlapping the 2009 SONATA, 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.

Engine leaking oil from the front cylinder bankâs valve cover or leaking from the valve coverâs gasket onto the alternator. A sufficient amount of oil could damage the alternator resulting in illumination of the charging system warning lamp and disablement of the charging system. If the vehicle is continually driven with a disabled charging system, the engine can shut off, increasing the risk of a crash.

Brake Calipers are getting stuck often damaging the rotors and pads. This happens even for new calipers and rotors that won't last more than one year after replacement. The parts were original from manufacturer. The rear and front brakes were randomly getting stuck on one wheel after a period of using brakes. This put the vehicle in danger of getting fire from overheating rotors or increasing the risk of a crash because of an unusable brake system. This incident has repeated over time from 2017 till 2025 inducing big spendings for fixing brakes

Excessively cracked dashboard. The entire dash in my 2009 Hyundai Sonata is cracked and a replacement has been denied by Hyundai USA. A cracked dashboard could cause reduced structural integrity. The dashboard is a structural component designed to help absorb and distribute some of the forces in a collision. Cracks can compromise this ability to perform this function potentially increasing the force experienced by the occupants and the and other parts of the vehicle. It can also cause increased risk of debris and shrapnel. During a collision the cracked dashboard may break apart more easily causing sharp or jagged pieces to become projectiles inside of the cabin these fragments can pose a serious injury risk to occupants. It can also result in an impaired airbag deployment. Many vehicles have airbags in the dashboard a severely cracked dashboard could obstruct or improperly deploy airbags for example the air bag may not fully deploy reducing its effectiveness and the dashboard may pun
