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.

- San Antonio, TX, USA

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 rpm increases 700 to 1000 rpm regardless of the speed

- Chesapeake , VA, USA

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.

- Hamlin, TX, USA

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.

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.
