Reference Number: 11520065 This is a follow up to a previously submitted incident involving this same vehicle. My first submission was May, 2023, This vehicle experienced the exact same hazardous condition on February 26, 2024. on I-75 south. After driving on an interstate highway for about 1 hour, I noticed a traffic backup and proceeded to slow down as the traffic was nearly stopped. As I slowed my car down to nearly a complete stop, the engine suddenly surged forward with high rpm's as though the accelerator was pushed to the floor. I immediately pressed on the brake pedal as hard as I could to stop the car from surging forward and then quickly decided to put the transmission into neutral so I would not hit the car in front of me. The car eventually stopped surging and may have stalled. I finally got the car to move again by turning off the ignition and restarting it. I continued on my way and did not have a similar situation for the rest of my 30 minute highway trip. Like all the times before, the floor mat was NOT involved in this sudden acceleration. Last year when I took this car to a Hyundai dealer for inspection, they could not replicate this condition. They said that I needed a new fuel level sensor in my gas tank and a new fuel pump--neither of which I agreed to because first, the gas gauge has no relation to my surging and second, the fuel pump must be working or else I could not drive the car. This surging has occurred perhaps 7 times since I have owned this car since 2008. It is frightening to know that it could happen again with personal injuries or property damage. This condition rarely happens in city driving, but has happened at least 3 times in city driving. Seems like this situation would warrant a manufacturer recall.

Valve cover leak or head gasket leak

- Graham, TX, USA

On highway, car would no longer accelerate and went into limp mode causing me to slow to 50 mph and not be able to keep up with speed if traffic. Pulled over, dash lights flashed and car would not restart. Oil had leaked out of valve cover gasket all over the alternator causing the car to malfunction and become inoperable.

With only a little over 113,000 miles on the vehicle, the transmission began, without warning, making a jet engine type whining noise when accelerating, and a noticeable whirring noise with a fairly rough "wind down" of the transmission when decelerating. No indications of a an impending failure were noted prior to the transmission symptoms being noted. Online research indicated that these were the same exact symptoms noted as a result of a recall of nearly 6000 2010 Hyundai vehicles, which required a recall of these vehicles. The 2008 Santa Fe in this case has the same or very similar transmission and engine configuration, and at least one other 2008 owner has complained of this situation. In addition, in discussing this with the Hyundai dealer service manager, he stated that there are problems with the transmission and that there are very few, if any, in stock and have to come from the manufacturer in atlanta due to the demand for replacements (latest estimate is 10 days to 2 weeks just to get the parts!). now, Hyundai has been "gracious" in agreeing to pay for half of the cost (so nice, considering it only has 113K miles on it before it failed), but I believe strongly that the campaign 102 recall actions associated with the 2010 Santa Fe vehicles needs to be further examined, and I believe strongly that it will be found that the same conditions, need for recall and kit installation, etc. Forget the year models which seems to be the focal point - Focus on the transmission parts and model numbers, and similar configurations, please! the Hyundai dealer has provided Hyundai with part numbers, diagnostic information, technician observations, etc. No visible damage (hence no photos) was discernible on my (the owner's) part. Transmission failure occurred while driving in Colorado springs (permanent residence in broken arrow, ok).

The car will not shift into drive. Very hard to shift and when I finally got it into "drive", the transmission does not engage. Unable to move the vehicle forward. It will go into reverse, but not drive. Shifter becomes harder to move after attempting to move it several times. The car was stationary.

Hyundai's slave cylinder is a faulty part known about online and in mechanic shops. It has failed twice in 65,000 miles and caused additional damage. It recently failed while driving as the vehicle slowed to turn and shifted to accelerate again. The clutch was damaged by this part and we had a $2,000 bill. There was nothing wrong with the clutch prior to this and the dealership even informed us it was damaged by the slave cylinder. Hyundai doesn't consider the slave cylinder "part of the powertrain warranty" and is denying our claim for reimbursement.

The contact owns a 2008 Hyundai Santa Fe. While driving various speeds, the contact heard a whining noise. Also, when the contact shifted from first to second or from third to fourth gear, the transmission shook violently and the engine warning indicator illuminated. The vehicle was taken to the dealer where it was diagnosed that the purge valve needed to be replaced. The vehicle was repaired. After the repair, the failure recurred several times. The vehicle was taken to the dealer, but was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 41,432.

After several hours of normal highway driving, the vehicle experienced a sudden loss of power as the engine computer entered "limp home" mode. Pressing the accelerator had no effect. Diagnosed as throttle position sensor failure. This problem occurred several times, with an engine restart clearing the problem temporarily. While these incidents did not result in a crash, they could easily have, depending on traffic circumstances.

This vehicle has developed a speed sensitive "whirring" sound while the transmission is engaged. We initially thought it was a tire noise, but did not go away when new tires were installed. The dealership told us it was the drive belt rubbing against the cover, but further investigation by another repair facility found no excessive wear on the belt, and no indication of contact with the cover. The noise is actually coming from the transmission, and is exactly as described in recall 102 which applies to 2010 models. I plan to start a fight with Hyundai over this repair as the transmissions are the same on the 2008 models as the 2010.

While driving on I-95, the charging system warning light came on followed by a loss of engine power and then engine stopped completely. Was able to safely make it to the road side. Dealer diagnosed a defective valve cover gasket allowed oil to leak which dripped on and into the alternator causing it to fail. Second identical failure on vehicle in two years. V-6, automatic, 2wd. Found manufacturer just issued a recall on veracruz model which shares the same platform for identical symptoms and failures.

The Santa Fe gas gauge behaves erratically! as you drive, the fuel indicator needle moves up and down so that you do not know accurately how much fuel remains in the gas tank. The needle may also indicate a very low fuel level by illuminating the "low fuel" warning light on the dashboard as well. The problem appears to be getting worse as drive time goes on as the needle movements increase the longer time the SUV is driven and the volume of fuel decreases in the fuel tank. After a period of time the check engine light will also illuminate to warn of a vehicle engine / drive-train problem. In my case I have reset the check engine manually and after a number of trips the check engine light will reappear. This low fuel warning cycle has been repeated numerous times and may cause a driver to be distracted to see the low fuel warning light, when in fact there may be sufficient fuel in the gas tank. I find that this problem is very disconcerting as you don't know whether you may be running out of gasoline.

Throttle accelerated by itself and was stuck wide open. Could not get the throttle to disengage. I tried tapping the gas pedal several times and this did nothing. Managed to hold both feet on brake and downshift into low. I got vehicle onto shoulder and put it in neutral and the engine continued to run full throttle. I shoved it into park and turned the key off. The engine did not disengage until the key was turned off. Very bad for transmission to shove it into park but I had no other options. Very scary. I have been told that there is no recall. I called Hyundai and filed a report but they have not called me back yet with repair options.

I went to put my car into reverse and it got stuck and wouldn't allow me to shift into drive or any other gear for that matter. The whole shifter is now being removed.

See attached email updated 06/04/2013 the occupant classification system (osc) does not consistently recognize small-statured adults, causing the passenger side air bag to deactivate when such person occupy the front seat. Also, there were problems with the transmission, a knocking noise coming from the front of the vehicle, the vehicle shutting down, an issue with the throttle cable, and a whining sound upon acceleration.

2008 Hyundai Santa Fe will not go over 20 mph. After pressing on the brakes several times it starts to move again. I took the vehicle to the Hyundai dealership because the check engine light also came during this ordeal. The dealership said they fixed the problem, but it has rear its ugly head again. The check engine light is on and it will not go over 20 mph. I am not the only owner of a 2008 Hyundai Santa Fe who has experienced this problem. Please contact the Hyundai manufacturer to solve this problem, because it can lead to a serious traffic accident if it's not fixed. Let's be proactive this time instead of waiting until someone is in a fatal accident.
