Last march I noticed the check engine light on and the vehicle hesitating to stalling out when cold and accelerating. This is worse the colder it gets outside. Also when driving you can feel a hesitation/missing going on, almost like the gas isn't flowing steadily into the engine. And recently my gas gauge is not showing accurately what is in the gas tank. I'll fill up and it still reads empty with the low fuel light on and check engine light on. It'll eventually after few start ups start to "supposedly" display the correct gas amt on the gauge. I reset my trip meter to measure how many miles on the tank so I don't run out. But the stalling on acceleration is a big issue. This could happen at a light or stop sign and end up causing an accident. I've read on this sight others having same problem.. I had same problem with a gmc envoy, about the same year as my hyundai, gmc made good on the problem and covered the expenses as they had a "silent" recall on that issue. Hopefully hyundai will be doing the same, we'll see after thursday night.

Brake light module fails to light up, which causes higher risk of collision. There is recall on this, but this does not cover my vehicle. This vehicle has multiple problems, all of which are hazards. The gas gauge needle does not function properly, and shows erratic gas usage, even showing the low fuel light right after filling up. The ESC light stays on, which causes the engine light to stay on. And the vehicle will hesitate at times when the gas pedal is depressed. All of these issues have been reported by other santa fe owners.

My experience and observation is same what is explain in the earlier post. I car does have brake light switch failure which was not covered under the recall. Unfortunately I have shell out $70 from pocket to fix it. The hyundai dealer (hyundai mark zimmerman) charged me $291 for fixing the tps and programming the ECM. When I would begin acceleration the vehicle would hesitate then take off rapidly then I would loose power to a speed of @ 25 miles per hour and the ESC off switch would appear on the dashboard followed by the check engine light. I safely pulled over and turned the vehicle off for about 30 seconds. Once I turned the vehicle back on, the dashboard lights would go out and I would repeat this cycle 8-9 times before being able to drive normally. On several occasions after driving normally for about 10 miles the ESC off light would reappear on the dashboard in my opinion this is a serious malfunction and certainly dangerous combination and should be labeled as a recall. Hyundai should value the safety and expectations of their car buyers. Thanks!

On several occasions after driving normally for about 10 miles the ESC off light would reappear on the dashboard and I would loose power while driving sometimes on a highway which was extremely dangerous to go from 60 MPH to coasting at @ 15 MPH. Diagnosis from the car dealer is the throttle position censor and throttle body part. In my opinion this is a serious malfunction and certainly dangerous combination and should be labeled as a recall. Hyundai should value the safety and expectations of their car buyers. When we as consumers purchase a vehicle we expect an excellent quality product. I researched this vehicle before purchasing and was LED to buy it because of the many solid qualities I found. As a consumer, I am disappointed in this malfunction and equally disappointed in hyundai for not stepping up to the plate to correct this major safety, quality and important issue. Furthermore, I was in the market to upgrade my sante fe, however now I will be looking into another vehicle to purchase.

Car began accelerating as if cruise control was on. I put my foot on the brake and the car hesitated for a second. My foot then returned to the gas pedal and again the car began to accelerate at a very fast pace. My foot then returned to the brake and the speed continued to increase. I then put the car into park and shut off the ignition. Prior to turning off the car the speedometer showed speed of 90 miles per hour. My vehicle then rolled to a stop. When the tow truck driver attempted to start the vehicle the steering column was locked and he was not able to turn the key in the ignition. The car was towed to the hyundai dealership. The following morning they claimed they could not find anything wrong with the vehicle and suggested that the incident was caused by my floor mat.

Brake failure almost caused me to skid through a red light that was at 50 miles a hour highway intersection. The car was purchased new 7/18/2007, and was recently inspected by the dealer as part of a 15,000 mile check up at that time I expressed a concern about the car's hesitation upon acceleration november 5, 2008 I was told that my 2007 hyundai santa fe had it's rear brakes locked on and the whole rear brake system needed to be replaced and I skidded because they had failed and my front brakes were doing all the work. I was told by many car specialists that this should not have happened with a vehicle under 18 months with only 15,198 miles and that it is a problem with hyundai's inferior brake system and that it will happen again! I fear that next time, I won't be able to stop and lost of life may occur.
