2010 Hyundai Genesis Owner Comments

problem #4

Jul 302015


  • 24,500 miles


My 2010 Hyundai Genesis was recalled for a defective faulty break switch in 2014 and the required service was performed 7/30/15. The following day I engaged the cruise control at 75 mph but almost rear ended the car in front of me because the integrated speed control did not activate. The cruise control also turned completely off at times. I've returned the car twice to remedy the problem and was told they could not find a solution and have requested assistance from Hyundai. I waited almost 2 months with no word from Hyundai and finally went to the dealership on 9/22/15 and was told they were still waiting for instruction from Hyundai and they now have a second car with the same problem. I feel this is very dangerous and want to post this listing because I believe lifes are at stake and owners of these vehicles will more than likely be ticketed for causing accidents and, worse case scenario, be charged with vehicular manslaughter.

1) almost hit from oncoming traffic at a stop light, when I was attempting to make a left hand turn. The signal turned yellow so I tried to turn left before I realized the oncoming car was going to run the light. I took my foot off the brake and hit the gas to make a quick turn to avoid the oncoming car. The car stalled for a second as I pressed the gas into the turn, then kicked into full power, screeching the tires. I thought this was a fluke but his same problem of "stalling" for a few seconds when depressing the brake and hitting the gas at takeoff keeps happening intermittently. This is a dangerous issue. When needing to accelerate quickly from a stop, this car has a seconds gap from hitting the gas to the car moving. I've almost been hit twice because of it. 2) the headlights switch off intermittently when using the turn signals to change lanes or turn. They flash oncoming drivers as I click down to turn them on before the turn, or when the turn signal clicks back after the turn. This problem happens almost every time I drive the vehicle with the headlights on. The lights have shut off completely for about 5 seconds while I was driving down the freeway, impairing my ability to see at night. I had to immediately pull over on the freeway in an unsafe location to turn the lights off, then turn them back on to clear the problem. 3) my vehicle had the brake switch replaced from the 2013 recall. However, pressing the brake still does not shut off the cruise control when driving down the freeway. I have to manually turn it off from the button on the steering wheel. I love this car, but I'm afraid to drive my children in it if these problems are not addressed. This vehicle is unsafe and it is going to kill or seriously injure people. Please investigate these mechanical problems and issue the appropriate recalls.

2010 Hyundai Genesis. Consumer states brake/ accelerator issues with vehicle the consumer stated six to eight months ago, he began to experience a troubling problem with the brake /accelerator, which manifested itself by frequently causing the vehicle to jump ahead or jerk forward when shifting his foot from the accelerator to the brake pedal usually when intending to come to a stop. At times, the tendency for the vehicle to continue to move forward required an immediate strong braking effort to overcome that tendency and to actually stop the vehicle. The consumer stated he had only experienced the problem, while in forward gear.
