2006 Hyundai Santa Fe Owner Comments

problem #16

Santa Fe

  • 220,000 miles


Four separate incidents within a 30 day period at higher speeds (>65 mph on a freeway) of unintended acceleration, remediated by shifting into neutral and braking hard without pumping. These actions disengaged the acceleration without having to come to a complete stop and turning the ignition off. Unintended acceleration occurred again, in the latest incident while traveling at 40 mph on a city street, however car would not come to a complete stop even with full weight on the brake, and while shifting into neutral solved the immediate acceleration problem, the ignition had to be turned off to bring the vehicle to a full stop. Driver almost wrecked several cars while trying to Dodge traffic as car accelerated very rapidly. This could have been had a tragic ending but fortunately only resulted in a mechanics' visit.

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. So after a few weeks of noticing this problem, taking it to the mechanic and having the throttle body cleaned, and a gasket replaced the vehicle has now started to rev up on its own after I release the gas pedal when driving at high speeds of 80 or over. I let off the gas then it revs up quickly to 4000 then again quickly shoots back down below normal. It didn't do the highway problem as much I noticed when the fuel was low, but when I filled my tank the problem came back again. It did still rev on it's own from cold start the whole time still regardless of fuel level. I noticed this week it now jumps when I put it in drive or reverse after a cold start and the other day it seemed to lose its gusto as I was turning a corner, then it revved high and went back to normal. This is all very scary and I am concerned as I read more and more that this is a wide spread problem that could cause injury or fatality. No one seems to be able to say what the problem is, just that it could be a bunch of things.

Car races at idle while in park or neutral to 3,500 RPM. While in drive or reverse the car continues to race but at a lower level(1,200-1,500 RPM). The car surges while braking requiring harder pedal pressure than normal. Racing is continuous at all speeds requiring less accelerator pressure than normal. A complaint was filed today 1/19/15 with Hyundai and a case # 7614630 was provided. This owner expressed his concerns to Hyundai representative with safety of car due to racing and surging especially under wet or ice conditions. The rep. Scheduled a service appointment with the Hyundai shrewsbury, NJ dealership for 1/22/15.

The contact owns a 2006 Hyundai Santa Fe. While driving various speeds and making a right turn, a squealing noise emitted from underneath the vehicle. Also, the vehicle lunged forward when making a turn. The vehicle was taken to an independent mechanic. The technician discovered that the steering shaft was bent and needed to be replaced. The vehicle was repaired, but the squealing sound continued to occur. In addition, the failure caused the front passenger side tire to deflate. The manufacturer was not notified. The failure mileage was 5,000.

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. When all this happens the engine light will come on and than go off, sometime now the engine light comes on and stays on for a few days and the car has a lot less power or feels like its going to stall, than the light will go out on its own. I had it checked out and they told me I needed an alternator so I bought one when my son and my neighbor was going put it in they checked the alternator and battery and they were fine and have been checked several times and are fine. Also at night when I press the break to stop or slow down the head lights will dim and I can feel the jerking of the care just a little bit. I am so afraid to drive this care sometimes or on the beltway because I am afraid its going to stall/shutdown or shut off that its going to get me killed and I am also afraid to drive my grand children because of the same reasons. Please help me! I can't afford to keep getting it looked at when it doesn't happen all the time they can't find anything wrong with it. What can I do to fix this problem. When this happens I have no steering or control of the car for that split second and I am an emt/firefighter I know that split second can kill me and anyone else in my car. I had bought the car used last year and it was doing it just a very little bit at first and I called the used dealer and he said its bad gas.

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. I have filed a complaint with Hyundai, but so far, they have not sent an investigator to check out the vehicle.

Santa Fe 6-cyl

  • 55,000 miles


I have a 2006 Santa Fe 6 cyl. Front wheel drive. I purchased the car in 2007 from go Hyundai. The car has run very good, except the surging or acceleration problem. I took it back to the dealer two times specifically for this problem. They said they could find no problem. I took it to a second dealer, planet Hyundai, and they could find nothing. The problem got so bad even I was afraid to drive it. My wife was really scared to drive it. I finally took it back go and they called, said it was ready. When I picked it up, the service guy said they replaced a part and that I shouldn't have any more surging problems. Last night, my wife drove the Santa Fe to church. As she was parking it in the garage, (something she had done a thousand times), the car suddenly accelerated, slamming into our Volvo convertible, pushing it about five feet forward, jamming it under our stairs into the house. In all, there is a lot of damage to both vehicles.

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.

My 2006 Hyundai Santa Fe has experienced from the time of purchase a long lag time between depressing the accelerator and the vehicle starting to move. The time can be up to a few seconds. This has been annoying and at times dangerous. If the vehicle always did this, you could get used to it, though it is still not safe. Unfortunately, there are times when barely depressing the accelerator results in instant tire spinning and associated quick acceleration. The inconsistent nature of the accelerator response makes the vehicle dangerous. As my daughter is learning to drive, I cannot let her use the vehicle because with any inexperienced driver, this car would be deadly. I have brought the car to the dealer once (in pa) and was brushed off with the excuse that the engine computer did not report any problem.

Santa Fe 6-cyl

  • Automatic transmission
  • 23,000 miles
At the recommendation of the dealer mechanic I had a transmission flush done. Now the car idles erratically, and surges when slowing to a stop. At times.when stopped the idle drops to 300-400 rpms, almost a stall, and sometimes it jumps to 1200-1500 rpms and wants to lunge forward. I have to make sure I am really stomp on the brake, or else I would hit something. I took the car to the dealer, and they said they used the computer and found no codes, so nothing was wrong. They recommended an injector flush, though the car seemed to run fine at speed.

Santa Fe 6-cyl

  • Automatic transmission
  • 8,900 miles
#1 car would not stop, rolled through a stop sign and pulled over into empty lot and tested brakes a few times and then it was okay. #2 was stopped behind a vehicle about 2 feet away, with my foot on the brake when car accelerated and felt like it jumped and I bumped the car in front. This was on 11-28-06 about 1 1/2 hours after bringing my car to the dealer to tell them that my brakes sounded like metal against metal and was told that it was normal on foggy mornings. The same thing happened the morning before but I was told to bring it in the next day because they were busy. I don't remember the date of the first incident when I rolled through the stop sign but it was about 4 weeks before the second time. Dealer had my car for 2 days but could not duplicate the incident.
