The contact owns a 2014 Hyundai Sonata. While driving approximately 55 to 60 mph on a highway, the vehicle lost power. The accelerator pedal was applied, but the vehicle continued to lose power without warning. The vehicle was pulled over to the side of the road and restarted.

The approximate failure mileage was 28,000.

Steering wanders on a straight road. Driving in a straight line is nearly impossible. More noticeable at highway speeds, but also at city speeds, the vehicle requires constant correction to maintain a straight track. The car simply 'wanders' or 'drifts' left and right, with no real 'centered' feel to the steering. Maintaining a straight track is impossible and requires constant attention and correction. The steering wander creates hazardous driving conditions, especially on wet or icy surfaces and driver fatigue, which poses a public safety hazard. The vehicle has been brought to the Hyundai dealership over 10 times for resolution, and the manufacturer has been informed twice. The dealership and manufacturer denies there is a problem and states that the individual does not know how to drive and/or that the individual would have to wait for a recall. Hyundai us has not been responsive to complaints. Cruise control has failed to operate since vehicle was purchased new. Hyundai has attempted 3 repairs and are now denying claims.

As I was exciting the freeway I began to hear a "knocking" sound, as I made the turn on to the street the car completely shut down and all the lights on my dashboard came on. Since I was in the middle of the street I attempted to restart the car and after initially starting up it then abruptly turn off once again about 20 seconds later. At this point I managaged to pull into a parking lot with the left over momentum. Had to get it towed to the newrest Hyundai dealer. After they inspected it, they determined my crankshaft had seized and 2 and half weeks later here I am still waiting for an engine they say is on backorder.

Had a near death incident at freeway speeds in heavy rain when the car lost total control, hydro-planed from the 2nd to left lane and hit the cement barricade on the left and in the process the steering wheel is locked along with the brakes and with that impact, ricocheted all the way to the right hand shoulder of a 4-lane freeway before coming to a stop. Freeway is 280 S (san francisco to san jose). Location was palo alto, just a few miles after sand hill rd exit (menlo park) where the freeway is just straight for miles without any steep curves. Have driven so many other brands over the last 20 years in heavy rain on the same freeway without an incident. The car cannot handle freeway speeds and became very unstable. Could be defective tires, their technology controlling the wet traction which caused hydroplaning etc fortunately there were no other cars in proximity else could have been a bigger accident.

My vehicle has for the last year showed signs of the recall and we have gotten a Hyundai to fix it with a ring but the next day the vehicle showed the same things. The symbol in the middle that displays drive when it disappears the car struggles to accelerate and drive, and when I come to a complete stop with it disappereared the car takes alot of gas to accelerate. Which I believe is from the transmission and the car not being on the same page.. which is terrible as it can cost a lost of life due to the car suddenly stopping and it is a extreme hazard to myself and my family. And I wish that Hyundai would do something or replace the vehicle.

1) the miles per gallon reading is unpredictable its advertised to give around 27 combined but I have never reached that 27 mpg, though I drive in low RPM ) the vehicle does not slow down for long distance even after releasing the gas pedal resulting in abrupt braking in lieu of gradual braking in stop & go traffic 2) the drivers side seat malfunctioned at around 15,000 miles 3) the car has a leak from 1000 miles onwards but the service center refuses to help, I called Hyundai they advise me to call the service center, I feel as if after a valuable investment there's no customer satisfaction or customer redressed process. 4) lack of corporate service department that can answer warranty related questions.

As rptd to Hyundai motor amer. (hma) via cust. Care line & preliminary investigation rpt. Vehicle: 2014 Hyundai Sonata SE 2.0T sedan details of incident: Incident occurred while parking the vehicle in parking lot. Parking spot: Perpendicular parking (park between painted lines) curb, shrubbery and wall in front of spot (in that order). Approached parking spot, toward front of parking spot applied brake. Upon application of the brake the vehicle suddenly lurched forward --- felt like it was flying --- went forward and over the curb and stopped in the shrubbery before the wall (did not hit the wall). Seat belt prevented injury (head movement only). Fyi, no airbag deployment (given situation I would not expect deployment).
