2006 Hyundai Santa FE Vehicle speed control Problems

“On march 4, 2020, heading home at night on a curvy mountain road my car (2006 Hyundai Santa Fe) suddenly jerked, started to accelerate to over 80 miles hour. At the same time half of the panel light behind part of the RPM's and half behind the MPH went out; the rest of the panel was still lit up; I was heading down the curvy road accelerating heading quickly towards an 18 wheeler when I tried to brake, my brake pedal would not move and my car kept accelerating (I was not stepping on the gas pedal). …”

“At first I noticed that sometimes (randomly) when I started my car after sitting for a longer period like 6 or 8 hours that I'd turn the key and without pressing any pedals the vehicle's rpms start to climb up slowly. It max's out at 4000rpms and stays there for awhile then will decrease on its own after awhile (random timing always). If I step on the gas as its revving up it releases and goes back down. If I brake it does nothing. …”

“Occasionally, when accelerating from a stop position the car will unexpectedly surge forward. We have had this car for 3 years now and it has happened about 6 times so far. Consequences have been none so far, but I am concerned something may happen in the future.”

“Stopped at an intersection, foot on brake, engine began revving, then decelerated, but revved again, this time forcing my car forward. Another vehicle was approaching from the left, so I steered right. Impact on left front wheel, car careened into a lightweight plastic type fence and stopped. My foot remained on the brake the entire time. I was wearing my seat belt and was not injured. The other driver was transported to the hospital by ambulance. Both vehicles were inspected by the same insurance adjuster and totaled. …”

“This happens more often than none now. I can be pulling out into traffic of just cruising along when I press gas to go whenall of a sudden the car jerks, looses power! Like its going to stop and stall in one quick second and throws me forward even with my seatbelt on it jerks me I only had it stall one time, so far. If I let off the gas and press it again it seems to help and power comes back, sometimes. I almost got hit pulling out into traffic because the car lost power and wasn't going anywhere when I had gas peddle pushed. …”
