2014 Hyundai Santa FE Sport Vehicle speed control Problems

“While driving on the interstate, I noticed a rattling/knocking noise coming from the front of the vehicle, under the hood. The noise kept getting louder, specifically as the vehicle accelerated. I noticed that the rpms would increase, with no increase in speed & even a decrease in speed. During this time the car was using cruise control at approximately 70 MPH. As I noticed the knocking noise getting louder, I tapped the brakes & the vehicle's speed dramatically decreased to approximately 40 MPH. …”

“My vehicle was involved in the engine recall which caused the vehicle to completely shut down due to engine failure. After having the engine replaced by a Hyundai dealership, the vehicle continues to intermittently loose power without notice. Although, the tachometer reads 7000 RPM, the speed is 20 MPH with the pedal to the floor boards. This happens without notice and has happened on interstate highways with cars speeding buy! We have to pull over and shut it off and then restart. Then it will be fine til next the next time. …”

“Car was in park at take out window, when I put the car in drive and took my foot off the brake, the car lunged forward without my pressing down on the gas pedal. The car was hard to control. I was able to pull it over and stop, when I did the engine light came on. I shut it off, waited a few minutes, started it up, drove around the parking lot slowly and it seemed to be back to normal. The engine light stayed on for 2 days while it was parked in my yard, not using it. I drove it to my automotive shop to be looked at and while driving there, the light went out. …”

“When taking off with the vehicle it will die and almost come to a complete stop then the engine picks back up and continues on down the road does this every time you start and stop. Will not get on 200 rpms or 60 MPH. This is the second time I have had the car in the shop for the same issue. First time they kept my car two months said it was a wiring issue. 2000 miles later does the same exact thing almost causing me to get in a wreck because it starts with no warning at all. Car currently back in the shop been there now a week have not heard anything from them.”

“I am reporting a severe safety failure on my 2014 Hyundai Santa Fe Sport that perfectly matches the safety defect described in Recall 21V-303 / Campaign 205. This happened even though I had the dealer perform the official recall fuse fix back in 2024. The problem started after I left the car parked for about 3 to 4 hours. When I came back, I heard a motor (not the motor) loudly running under the hood even though the ignition was completely off. It stayed on even after starting and turning the car off. …”
