At highway speeds the car wanders all over the road. It requires constant correction to keep it in the lane of traffic. I just returned from a 3000 mile trip and I became very exhausted with having to constantly be. On the alert and correcting the steering. It is way too sensitive and does not track down the road as it should. I took it too the dealer and they informed me there was nothing they could do to fix the problem.

Vehicle wanders from lane to lane requiring constant correction. This condition causes fatigue when traveling at highway speeds. Vehicle driver can not take their attention off the road for more than a few seconds, especially in windy conditions or heavy traffic as the vehicle will wander. This causes premature tire wear tires must be replaced in as little as 10,000 miles and the cost is about 1K for all four tires. Problem two. Cruise control will not set or cancel must be turned off, or the brake depressed or the control buttons are inoperative pressing the cancel button does not turn off the cruise and if it does, after numerous attempts, the cruise will not reset.

Cpsc: I1360329. 2013 Hyundai Sonata. Consumer stated the steering locks and she cant start the car. The consumer stated she was stranded twice, because she was unable to unlock the steering wheel. When she was able to unlock the steering wheel, and start the vehicle, it would run in a rough manner. The consumer also stated she injured here wrist, hand and arm, trying to unlock the steering wheel.

Vehicle wanders dangerously from speeds of 35 mph to 60mph. I have other friends with Sonata have same problems.

Vehicle drifts left and right at interstate highway speeds, requiring constant attention and correction by the driver, which is distracting and contributes to driver fatigue. Unable to track smoothly around curves. Similar to alternating cross winds, even when there are none. Situation very aggravating in actual cross winds. Any police officer would be justified in issuing a ticket for "weaving". dealer technician drove the car and acknowledged that this is a negative characteristic of electrical steering and nothing to be done for it. He supposedly changed some setting from "hard" to "soft', but that had no effect after I left the dealer, maybe even being worse. I complained to Hyundai on their website, with no response to date. I am a professional engineer (mostly aviation) and suspect that some damping needs to be applied to the steering system. At this time, I am noticing that about half of the 2013 Sonata complaints concern the steering system. NHTSA should take action before accidents begin occurring due to this obvious safety defect.

I just purchased a 2013 Hyundai Sonata. The car tends to wander on the highway mostly left but sometimes right. It will not stay straight. I have already brought it back to the dealer twice and they tell me that it is within spec. At first they tried to tell me that it was because I was not used to electric steering. This is not the case. I have test driven other vehicles with this type of steering that do not exhibit wandering on the highway. I found out belatedly that this problem was much worse in the 2011 and 2012 model years and that they implemented a fix. Well the fix doesn't work. In addition when accelerating from a slow speed the car will pull left. The dealer has referred me to Hyundai corporate where I have opened a case number. They now tell me that there is nothing they can do since the dealer says it is operating in spec.
