Drove my 2015 Hyundai Elantra on the coldest day of the year to an appointment. Car was fully warmed up. Pulled into a gas station to park and was going less than 3 mph, making a left hand turn into the space. Elantra suddenly accelerated hard and the car hit a cement pole, causing extensive front end damage. If car had full insurance coverage, it would have been a write off. Hood crumpled, radiator damaged, front grill broken, bent the engine bar in half. Significant damage but the air bag did not deploy. Had to have it towed home 35 miles. Damage was in the middle of the front of the car, so I was already in the parking space. No warning lights of any sort before this happened. Very dangerous and I would never buy another Hyundai. I bought this car brand new in 2015 and have had recalls taken care of (anti theft software one). Over the course of owning this car, other odd things have occurred as well, such as white smoke coming out of the engine upon acceleration, accelerated wear on the tires due to the back end, and engine will suddenly stop for no reason while driving (this happened twice) Inferior product!

On [XXX] I was parking in my parking spot outside my house, went to pull up 3 more inches in my parking spot when the vehicle accelerated at an extremely rapid speed, went over the high curb, up my front lawn into the tree in my front yard. It was a battle between the brake and the gas acceleration event. Then I put it gently in reverse, my car fled rapidly down into the parking lot at such a high rate of speed, I turned the wheel, my car hit 3 cars across the parking lot, shot across the parking lot, popped over that curb, went down an extremely steep hill, hit the cross street, went still in reverse over an island, wiped out two signs and crashed into a car in the middle of the 4 way stop and stopped. My insurance is blaming it on driver error like they are blaming thousands of drivers over the same experience, stating that I mistook the gas pedal instead of the brake and also stating that I did not attempt to brake, that is so far from the truth, you can look at the track marks on the ground and tell I was standing on the brake. What is being done about these awful scenerios. My car is currently in copart being assessed. My car was serviced at the hyundai dealership ever since I purchased it, all the records are there and in my possession, I had low mileage, less than 48,000 miles and planned on holding onto the vehicle for at least 6 more years. Now my car is sabotaged, being blamed like 1,000 of other drivers over the car malfunctioning. There is a sensor for the Throttle, a sensor for the Gas Accelerator that the Computer Control Unit brain waits for the analytical data from both sensors and adds additional throttle to the situation. Once the car is turned off the entire system resets itself, so there is no evidence of high throttle, gas accelerators sticking and the driver is blamed. Since the insurance companies have insured these vehicles there is a lot at stake for these cases to be proven and for the Hyundai manufacturer as well.

I STOPPED AT A LIGHT AND WENT TO MOVE UP A FEW FEET. I TOUCHED THE GAS PETAL AND THE CAR FLEW INTO THE TRUCK IN FRONT OF ME. AIRBAG DID NOT DEPLOY WITH THIS FRONT END COLLISION. I WAS ON A 4 LANE DIVIDED HIGHWAY IN 5 O'CLOCK TRAFFIC. NO RAIN. I AM UNSURE IF IT WAS THE GAS PETAL OR SOMETHING TO DO WITH THE GAS LINE ITSELF

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2015 Hyundai Elantra Hev verdict →
