This vehicle started showing issues with key fob not working - gas gauge not accurate next cruise control light on also check engine light pointing to bad fuel pump sensor units - I've researched this and this is known issue - my car has only 70 k miles on it and huyndai refuses to do fix as this is not a recall and car is out of warranty - I say this is known issue and huyndai should cover this as a recall - vehicle is now unsafe and can shut off at any time during driving.... Serious safety issue. This is a known issue multiple reported complaints and calls for recall but huyndai will not offer recall - serious safety issue huyndai does not care - example of same complaint filed by another person on this same issue attached - multiple issues listed at this site : https://www.aboutautomobile.com/consumer-complaint/2008/hyundai/santa-fe/11141800. You can see all the instances this should be a recall on these vehicles ! *tt

Was on an interstate with cruise control set to 65 MPH. Was attempting to pass another vehicle, thus depressed the throttle pedal. The throttle stuck wide open. Applied brakes but kept on increasing speed. Depressed throttle pedal several times but no change. Turned cruise control off, no change. Had to pull over, put vehicle in park with brake pressed and turned key off. Waited several minutes then back on, throttle pedal started to respond. Second instance, was accelerating to merge onto interstate from a ramp, had previously had cruise control set to 65 MPH, throttle stuck wide open, again had to pulled over, put the vehicle into park, and turn off ignition . I checked to ensure floor mat was not interfering throttle pedal, it was not. Problem has recurred 4 times now on this vehicle all while trying to accelerate to either pass a vehicle or merge onto an interstate. All times the cruise control had been engaged.

6/25/14, on interstate with cruise control at 65mph. Depressed the throttle pedal to pass a vehicle. Throttle stuck wide open. Applied brakes but kept on increasing speed. Depressed throttle pedal several times but no change. Turned cruise control off, no change. Turned key to acc and then back to on but no change. Turned key to acc and waited several seconds then back on. Throttle pedal started to respond. Pulled over and checked if floor mat was jamming throttle pedal. No problem, no jamming. Problem repeated again. Continued to destination and tried cruise control but it would not set. Turned cruise control off. Suv was parked overnight at destination. On return trip throttle and cruise control worked fine. 6/30/14, took SUV to ray brandt hyundai, they found no codes set and could not duplicate the problem. It seems if both the throttle is wide open and the brakes are being applied then a code should be set.this is a major safety problem!

While driving my 2008 hyundai santa on the highway on two separate occasions last week my santa fe decelerated unexpected to ~ 20 MPH. The first time the car was on cruise control and started to lose power, the second time I was also using the cruise control and the same problem occurred. At the same time the ESC warning light came on followed by the check engine light. The temperature was cold but the road conditions were dry the vehicle failed to accelerate. I took the car to the dealer and the they were able to fix it by replacing a sensor. This could have resulted in a very dangerous situation on the highway. The SUV failure and current mileage is ~ 25,400 miles.

I have a 4 month old 2008 hyundai santa fe. I was driving it on the freeway and took my foot off the gas to get ready to brake for my exit. When I took my foot off the gas pedal the engine kept revving and pulling the car forward. I didn't know what to think. I immediately hit the breaks to see if maybe the cruise control kicked in, even though I didn't go near the cruise control. When I hit the brakes, much to my horror, I had no brakes!!!! I punched the brake pedal to the floor a bunch of times and nothing!!!!!! I had to step on the emergency break, put the car in neutral (to keep the engine from revving on its own) and drive my car into a hillside on the side of the freeway to stop it! It's a miracle that myself and my passenger were not harmed and that I didn't kill or injure anyone else. Unacceptable for a new vehicle or any vehicle to have this happen.
