| Component | VEHICLE SPEED CONTROL |
| Product type code | VEHICLE |
| Description of the problem | Issue: cruise control speeds up too much going uphill, and slows down too much going downhill. Description: i set my cruise control to 75mph, the car will go over 77mph when going uphill, and slows down below 73mph when going downhill without any driver input. This doesn't occur on other gasoline only hyundai i drove such as santa fe. It only happens on my sonata hybrid. I guess hyundai may need to look into how the electric motor works with cruise control. |
