Five problems related to cruise control have been reported for the 2020 Hyundai Elantra. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2020 Hyundai Elantra based on all problems reported for the 2020 Elantra.
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.
2020 Hyundai Elantra. Consumer writes in regards to cruise control problem. The consumer stated engaging the cruise control can cause higher rpms to maintain the set speed. This can cause extra wear on the motor and decreased gas mileage. The cause of the failure may be due to the new variable speed transmission.
2020 Hyundai Elantra. Consumer writes in regards to unintended acceleration. The consumer stated the cruise control was activated. While driving up a hill, the vehicle sped up past the set speed. The dealer and manufacturer were notified and stated the vehicle was operated as designed. While driving, the steering suddenly jerked to the left about 1. 5 inches. The dealer turned the sensitivity level on the lane assist. Also, the vehicle does not a metal screen over the air intake for the heater. This could allow rodents to enter into the cab.
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.
