2007 Hyundai Sonata Owner Comments

problem #3

Jan 192010

Sonata 4-cyl

  • 6,000 miles


The 2007 Hyundai Sonata gls with a 2.4L I4 engine and 4 speed transmission has serious shudder issues at 45mph. The vehicle almost becomes undriveable due to the shudder and has to be sped up to speeds above 45 mph which is beyond the posted regulatory speed limit on the roads.

problem #2

  • 32,000 miles
The contact owns a 2007 Hyundai Sonata. While driving various speeds or idling on an incline, the vehicle spontaneously rolls backwards as if it had a manual transmission. This increases the risk of a serious crash or injury. The contact took the vehicle to the dealer and they stated that it was a common characteristic. He called the regional representative, who acknowledged that there was an issue, but never took any action. As of October 8, 2008, the failure has not been remedied. The failure mileage was 32,000 and current mileage was 36,000.

problem #1

Jun 062008


  • 7,600 miles
On June 2, 2008 the ESC (electronic stability control) light on the dash indicated the ESC was not engaged. It went off after I stopped the car and restarted. The light came on 2 more times in the next 4 days. On June 6, I was making a "Y" turn on a residential street and the shift would not move out of drive. Having read the owner's manual previously, I popped the button on top of the shift console and pushed the button with my knife. I was able to get into reverse, but the shift locked down again keeping me from going into drive. I had to push the button. I brought the car to my dealer on June 16. The brake light switch was faulty and sticking causing the problem. Since I have only 8,456 miles on the car, warranty covered the repair.
