2015 Hyundai Elantra Speed Control & Cruise Problems

Car will accelerate and get stuck in a high gear rpm gauge will not work as well You will come to a stop not knowing you are stuck in a high gear car will not downshift. I tried to cross the intersection from a stop and almost got hit because I could barely accelerate. I was stuck in 5th gear. Car will also stall while stuck in in a high gear at a stop I can turn off the vehicle and start it and it will reset the car to normal. It will drive fine for a while. Randomly this will happen. From my research I found this is a common problem with many different model years of Hyundai's . Most people say the solution is a new crankshaft sensor . When I ran a diagnostics There are no error codes for this problem. Many other individuals with this problem have said the same from many different online forums I have read. Other individuals I've said they were also stuck in the high gear at a stop and did not know until they accelerated. Some have been in accidents because of this issue. I would assume Hyundai would be aware of this. If there's not a recall on this, I believe there should be.

The contact owns a 2015 Hyundai Elantra. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to respond as intended. Additionally, the vehicle jerked and hesitated. The contact stated that an unknown warning light illuminated with a message not to drive the vehicle until the vehicle was serviced. The vehicle was taken to an independent mechanic where it was diagnosed with a failed transmission and that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was unknown.

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.

Unwanted sudden engine speeding up,No warning or messages.

WHEN I TRY TO ACCELERATE QUICKLY, ESPECIALLY IF THE ENGINE IS STILL COLD, I WILL SUDDENLY NOT BE ABLE TO ACCELERATE EVEN THOUGH THE ENGINE AND VEHICLE IS STILL RUNNING. THEN WHEN I SLOW DOWN THE VEHICLE BEGINS TO SHAKE LIKE IT'S ALMOST GOING TO DIE ALTOGETHER. THEN IF I TRY TO ACCELERATE AGAIN, IT'S ALMOST LIKE THERE IS NO POWER TO DRIVE,OR THE ENGINE COMPLETELY STALLS, AND THE CHECK ENGINE LIGHT BEGINS TO FLASH AND THE OIL PRESSURE LIGHT COMES ON. THE ONLY WAY THEN TO BE ABLE TO KEEP DRIVING IS IF I COMPLETELY STOP THE VEHICLE AND TURN THE IGNITION COMPLETELY OFF AND WAIT A FEW MINUTES AND THEN IT WILL USUALLY TAKE 3-5 TRIES TO GET THE CAR TO START AGAIN. THIS HAPPENS NEARLY 1-3 TIMES A WEEK, AND THE DEALERSHIP SAYS THAT IT'S NOT RELATED TO THE ENGINE RECALL THAT THEY ISSUED, EVEN THOUGH IT APPEARS TO BE THE SAME EXACT ISSUES THAT IS AFFECTING THE OTHER VEHICLES. THERE HAVE BEEN AT LEAST 20 OCCASIONS WHERE I WAS TRYING TO MERGE ONTO A HIGHWAY AND THEN MY VEHICLE DIES OR LOSES POWER AND THIS IS A HUGE SAFETY CONCERN OF MINE.

THE CAR STALLS WHEN YOU COME TO A STOP AFTER THE ENGINE HAS WARMED UP FROM DRIVING. STALLS EVERY TIME THE CAR IDLES AFTER WARM UP. CAR IS DRIVE BY WIRE WITH ALL ELECTRONIC GAS PEDAL AND THROTTLE BODY. NO MEANS OF INCREASING THE IDLE SETTING. STALLING CAN BE AVERTED BY KEEPING RIGHT FOOT ON THE GAS AND BRAKING WITH LEFT FOOT. NOT A SAFE WAY TO DRIVE.
