NHTSA Complaint #11545821 — 2013 HYUNDAI SONATA

What component or system failed or malfunctioned, and is it available for inspection upon request? The Car continues to have inconsistent acceleration, hesitation, and sometimes lurches forward. On two occasions, the car felt like it was just going to turn off while driving. I was driving about 75 mph on I295 and driving about 15 mph on a residential road during the second occurrence. How was your safety or the safety of others put at risk? I feel as though I am not in complete control of the acceleration but am mostly concerned with the car stopping on it's own. I am very scared I'm going to be hit by the car(s) behind me. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? I have an appointment in October for the car to be evaluated by a dealer. I hope it doesn't happen again before then. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? The only time a warning lamp came on was during the second episode when the car felt like it was going to turn off; the engine light came on and immediately off.
