2005 Hyundai Santa Fe acceleration problems

Filed Apr 16, 2025 · Acceleration · CA

While merging onto the freeway, the accelerator pedal got stuck to the floor with the throttle wide open. The brakes and emergency brake were ineffective. Measures had to be taken to drive off of the road into ice plant, we we were able to turn off the engine. Further inspection revealed a missing grommet at the wall where the throttle cable passes through to connect to the gas pedal. Furthermore, the plastic around the throttle cable was cracked, which allows for the throttle cable and pedal to push through and get snagged. This could have ended horrifically. We are lucky to be alive.

Vehicle had been accelerating on its own while driving low speeds and on the highway. There were moments when it lurched itself forward quite violently, more so after transmission had time to warm up. Have also experienced moments of deceleration without cause. Its as if the vehicle cannot properly shift gears. Check engine light came on. This happened over the course of a couple of weeks. Had vehicle looked over by mechanic but they could not replicate the issue. Vehicle is parked until another mechanic can look at it. It is by no means safe to drive until problem is fixed.

While sopped at a traffic light with foot firmly on the brake the vehicle suddenly started to accelerate. Applying additional pressure to brake pedal did not slow acceleration. I then shifted the vehicle into neutral. Within 2 seconds the acceleration started to decrease and returned to normal. Vehicle is scheduled to be inspected on 15 jan 2018. A similiar problem occurred in june of 2014 while I was backing into my driveway. At that time, I immediately shifted to neutral and turned the ignition off. An inspection by dealer revealed several cracked vacuum hoses and a faulty pcv valve.

On may 16, 2016 I was driving my 2005 hyundai on a city street and it started to surge and I had to put my foot on the brake to slow it down but it wouldn't stop. Luckily I was close to home and was able to get it in the driveway but the unfortunate part is it didn't stop until it hit my house. It was a very terrifying experience. I don't think I'm going to feel comfortable driving it again.

The passenger air bag light remains constantly when the engine is started until it is turned off. The cruise control doesn't turn on at all and the fuse is good.

While waiting for the traffic light to change to green, my car was stopped, with my foot on the brake. . My car learched forward. I could feel the engine accelerate. By the time I got the car under control, I hit the car that was in front of me. The trunk was damaged, no damage to my car. Since owning this car I have experienced this acceleration before. I have discussed this with the dealer, the discussing ends up with the dealer suggesting that I was pressing the gas pedal and not the brake. I told the dealer that when this occurs pressing the brake pedal does nothing. The shift must be moved to neutral the foot taken off the brake. Every time I discuss this problem with the dealer he says show him what happens, the problem I can not recreate the problem. The occurrence of the problem is random and cannot be created. At first I thought that I was the only one with this problem, but as I read the complaints I am not alone. Hyundai has got to look into this problem.

After a rain when I start the vehicle and start driving it is fine until I reach 20mph. Then it acts like it is not receiving any power. It will not speed up no matter how I press on the accelerator. I notice that if I put it in manual and go from 1st to 2nd it will straighten out and drive fine. But, if I put it back into automatic drive at a stop sign it will do the same thing stalling out at 20 MPH. If I drive it far enough with out stopping it will eventually straighten itself out. I am worried about pulling out in traffic because of this. We have done a tune up on it and it did not help.
