There is a serious problem with the Sonata! I am not the only one experiencing the engine cutting out while driving. Someone is going to be killed.
I had my engine cut out 2 separate times while driving. The second time I was almost rear-ended. My daughter also leased a 2015 Sonata. She experienced the same problem. I read reviews online, and it has happened to other drivers. I have had acceleration problems with the car since day 1. I had to bring my car back to the Isip location within the first week of the lease for a second key, so I asked them to run a diagnostic. I was told no "code" came up and nothing was wrong with the car. I go to the Hyundai service center in Valley Stream. They could not come up with a "code" either, but the mechanic knew I was terrified and the problem was real. At only 19 months old, I had the fuel pump in the gas tank replaced. It seems to have fixed the problem, Hyundai needs initiate a recall before someone gets killed!
