The contact called on behalf of their son who owns a 2020 Hyundai Elantra. The contact stated that while their son was decelerating, speed was unknown, and coming to a stop sign. The next thing their son was able to recall was that the vehicle had suddenly turned right crashing into an electrical pole nearby. The air bags deployed. The driver had lost consciousness during the crash making it difficult to recall all that occurred. The vehicle was towed but they had not yet received any confirmation if the vehicle had been totaled. The electrical pole had fallen and began to catch fire. The fire department had put out the fire. The contact was not completely sure of the damage done to the vehicle. The driver lost consciousness and received an injury on their right arm. Medical attention was needed. The contact could only assume a police report had been filed but had not heard from the police department to confirm. The dealer was not contacted. The manufacturer was not made aware of the failure. The failure mileage was unknown.
Car is almost stalling Randomly on the highway. The rpm-??s go up and car won-??t speed up slows down. Stalls very randomly I am terrified to drive it, I used to have so much confidence on a newer Hyundai.
Engine seized while going 55-60mph with warning lights only 15 seconds before my vehicle completely stopped on the highway [XXX] ) The engine was replaced by Hyundai along with the manifold and catalytic converter. Vehicle lost all control and power and started excessively knocking while I tried to get to the shoulder but only made it to the right lane. The safety of others and myself were out at risk due to no control of the vehicle. Repair order attached INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
When cruise control is activated, the engine RPM automatically increases by about 700 RPM. At 75 mph, the engine RPM is 2300. When control is activated, engine RPM increases to 3000 RPM and remains there. This decreases gas milesge and increases wear on engine.

Conditions: While driving on a flat road surface/terrain, maintaining a consistent speed, and consistent pedal application. If you set cruise control, the rpms will jump by 500 or more. The jump in engine speed is maintained, not temporary. The sustained increase in engine speed will reduce fuel economy and increase mechanical wear on the vehicle. This issue has been present since the vehicle was purchased brand new. I do have a video but the 5 mb file size limit prevents me from uploading.
I baught this car Sept 1st 2020, on October 3rd 2020 while driving the car pn my way to work on the hyway the transmition sliped and stopped shifting and wouldnt shift out of 2nd gear amd check engine light came on I was quick to put the hazard on avoiding collision from behind I took it into the dealership. Where they told me it would need a full transmition replacement due to manufacture defect. They are currently with gdpr the transmition to come so I'll have this loner car for the next 2-6 weeks.
While driving at 60 mph on a highway I engaged the cruise control. To my surprise the engine speed increased by 500-700 RPM. This seems to me to be a defect in the way the intelligent variable transmission (ivt) should operate or any transmission should operate. The result is that gas mileage will decrease and engine wear increase as a result of higher RPM than necessary. I believe this is a defect and should result in a recall by Hyundai to change the operation of the transmission. There are many complaints about this issue from owners. I have contacted my dealer and they, in turn, contacted Hyundai. I have also contact Hyundai customer care. As of this writing I have not received any indication from Hyundai that this condition exists and that it is a problem. I'm hoping you can require a recall to address the issue.
