In owners' own words
Takata recall. I was told that the electrical module is defective by autozone,. We were driving down the highway when all of a sudden the engine light came on.
While driving down the street, the car started slowing down with jerking and shaking like motions which was very distracting and caused me to become afraid in the moving traffic.
Taking my car for the first oil change since I bought it and the car stalled while in neutral waiting for an oil change.

Recalls for the 2009 Hyundai Sonata: 2
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. Control arm separation may suddenly change the rear wheel alignment, affecting the handling of the vehicle, increasing the risk of a crash.
In September 2013, Hyundai informed the agency that it was adding more vehicles to this campaign, representing an additional 652,512 units. In the affected vehicles, the stop lamp switch may malfunction. Failure to illuminate the stop lamps during braking or inability to disengage the cruise control could increase the risk of a crash.
A recall may cover only some cars of a model year; the campaign size counts every model and year it lists. Enter your VIN at nhtsa.gov/recalls: dealers fix open recalls free.
