I have a 2013 Azera. Occasionally, when I accelerate getting into traffic an a highway, the vehicle seems to die down. After I take my foot off the accelerator and accelerate again, the car acts normally. This has occurred several times. I brought it into the dealer twice and they could not find any problem. This is a serious issue, sinc the car could be rammed by oncoming traffic.
I looked at other problem forums, and found a similar problem listed for a Genesis. See quote here:
I've just bought my new 2012 Genesis sedan two months ago and have a very annoying hesitation problem when I'm going a under 5 miles/hour then try to accelerate. Nothing happens when I step on the gas for 1-2 seconds. Almost got me into an accident last week trying to pull into traffic. Took it to the dealer and they claim they could not duplicate the problem. That night, leaving the dealer it happened twice!
Today, I rented a 2013 Sonata for my visiting daughter, and experienced the same problem once. Any comments?
