NHTSA Complaint #11448428 — 2011 HYUNDAI SONATA

Everything worked good until I had to take my car to the dealer for knock sensor, air bag check, software update, and my engine was also part of the affected engine recall... well ever since then I have had to replace my car battery a few times and now I just invested in a battery charger because now my cars battery gets drained whether or not I use it? I asked the dealer on a couple of occasions to check out why my dash and lights flicker and shut off and come back on seconds later when I turn my lights on at night? also told the service writer that I noticed this happening when I used my turn signal, because I could notice the dash lights and head beams behave erratic and most dangerously? I know I was told more than once that they could not find nothing wrong and there were no codes either? I have to disconnect my battery now because of this dangerous issue and just gets very frustrating that now I have a car that sits there in my car port more than its driven nowadays but because car prices are high I really need my car repaired so that it could work safely like it used to before. I'm afraid that my car will catch on fire because of this and just wished that Hyundai Motor Corporation would look into this matter more seriously and more importantly find a solution for this big safety mater. I just finally got tired of all this that I have to go through and still probably wont ever hear of a safety recall for this big problem...
