2015 Hyundai Sonata SE - engine vibrations/rattles/droning when in overdrive at low RPM acceleration. At times the engine has been unresponsive. Was told by Hyundai it was normal, but did not start until the car had around 600 miles - now at 7400 miles, still doing it and sounds horrid. Also, popping sound from steering/brakes when backing up and turning/using brakes at only 1200 miles. That was fixed by dealer, said I had overheated the brakes, which wasn't true, only drove on freeway and wasn't using the brakes.

The steering wheel on this car will lock or get stuck as I am operating the vehicle. It has happened at slow speeds as well as highway speeds and even happened in reverse once. It is intermittent and random but the frequency is increasing. On my first dealer visit 12/10/15 there was a code for the electronic steering which the dealer cleared and returned the car to me without making any repairs. The problem continued so the car was taken to a 2nd dealer who found a code pertaining to ECM overheating. Hyundai advised the dealer to clear the code and return the car to me. I filed a complaint with Hyundai customer care on 12/16/15 and received an acknowledgment email that a representative would contact me in 3-5 days. On 12/21 I contacted Hyundai customer care, explained the car wasnt safe to drive so what should I do. I was told Hyundai would not offer a loaner car but I could ask my dealer if they would provide one at their cost. I asked about a representative contacting me and I was told it hasnt been 5 days yet so I needed to be patient. As of 12/30/15 I still have not received a response from Hyundai customer care.

In the snow, my Hyundai Sonata will drive fine until turning. During turning, even with minimal snow, my brakes lock up and my car slides slowly but at that point I am unable to do anything, usually making me hit a curb. This has happened twice in the last two weeks costing me $2200. I have had two cars before my Hyundai Sonata and haven't had issues with such a problem. The mechanic scratches his head in confusion as to how almost the exact same thing happen in such a small time frame. It is a major safety issue, I believe something with traction control or braking is wrong. Had I been a worse driver the damages could be worse.

Power steering motor failed. Luckily, it failed sometime between when I last drove it and when I attempted to drive it the next day. The steering was extremely difficult to manage, due to the failed motor.

I purchased my Hyundai Sonata on 1/05/2015 with only 6 miles from sheehy Hyundai of waldor in Maryland after 11 days of purchase on January 16 2015 at approximately 5:45 pm (rush hour in the DC metro area) my Sonata came to an abrupt stop without any warning signs on the highway in middle lane which is very dangerous and very scary and put me in a very vulnerable position. The engine shut off, I was unable to steer out the way of traffic and the brakes locked up and I was unable to do anything while in the middle of the rush hour traffic. I was a sitting duck waiting to get smashed by a pickup truck directly in the back of me.thank my god nothing happened. I was unable to use the sos and bluelink emergency features that is equipped came with 3 months free activation in this vehicle. I had to personally call via my cell phone and await police assistance which was 10 minutes still in the middle of the highway and after the assistance of the police we were only then able to push the vehicle to the shoulder of the highway. The bluelink customer service did very poorly in responding after all this emergency situation and to make it worse they did not provide a tow until 1.45 minutes after, then commence to justify this long period by stating its "Friday and the normal time is 2 hours or more". therefore, I am pleading to sheehy dealership and Hyundai corporation along with anyone else that can assist me to ensure that I have a new replacement vehicle. I am getting nowhere with sheehy dealership in reference to a new replacement vehicle. The vehicle is currently at sheehy service department and they are still not able to figure out the problem. Even though they might be able to fix the vehicle I will not feel safe driving the same vehicle after this very hazardous incident.
