The 2006HYUNDAISONATA carries 1422 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 55 crashes, 13 fires, 58 injuries, and 2 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 2006 SONATA is air bags with 375 filings, followed by visibility (150) and seat belts (96). 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 11 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 2006 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.

I am filing this complaint regarding a serious engine issue with my 2006 Hyundai Sonata equipped with a 2.4L GDI engine. My vehicle experienced [engine knocking, stalling, and then seized up indicating complete Engine failure] without warning, posing a potential safety hazard while driving. The issue appears to be identical to the known manufacturing defects that Hyundai has acknowledged in its recall of 2013â2014 Sonata models with the same engine Class Type. Although my vehicle is not currently included in the official recall â SONATA ENGINE RECALL CAMPAIGN it contains the Theta II MPI Engine which constitutes and Further solidifies proof of the ongoing Manufacturing Defects of Theta Model Engine design and exhibits the same symptoms of sudden engine failure. This raises concerns that the defect may affect a broader range of model years than Hyundai has acknowledged. I urge NHTSA to investigate this issue and determine whether the scope of the current recall should be expanded
