Check Engine Light On problems of the 2011 Hyundai Santa Fe

Driving on interstate 1 hour east of asheville, nc in heavy traffic. At approximately 230 pm on 8/20/2014 the check engine light came on, the car shuddered and lost all acceleration. Complete loss of power managed to coast to the side of the road and turned car off. Restarted and drove to Hyundai dealership in asheville, nc about 30 miles away. They performed a software update and stated problem was resolved. Continued driving on highway (traveling back to dayton OH), and within 1 hour check engine light came on, at about 700 pm, a complete loss of power and no acceleration, and had to coast to the side of the road, restart the engine, etc. Again, incredibly dangerous situation on a busy interstate. The same exact situation happened 2 more times on our way home on the interstate, until we could finally take it to our dealer where they replaced the throttle control assembly and did another software update. This was incredibly dangerous, could easily have resulted in a very bad accident and merits investigation. Please contact me if I can provide additional information. Thank you for your consideration.

Engine shuts off after taking foot off gas, slowing down and then applying gas to accelerate. After a short pause aproximately 15 to 20 seconds, the engine will restart and resume normal operation. No check engine light appears. The engine has three times in the last 14 months. Car was brough to dealer after first time and no codes or issues could be found. I will bring car back to dealer now after the third time. This is last stall resulted in a close call in heavy traffic.

While driving at slow speed 10-15 mph and braking the car completely stalled, once while turning left and once while going straight. Loss of power steering and power brakes and narrowly avoiding hitting another vehicle. No check engine light came on and no codes stored.

This complaint is similar to a complaint I already filed in December 2012 and is a recurring issue. On 3/18/13, was traveling approx 55 mph up a steep hill when the check engine light came on and immediately the gas pedal ceased functioning as well. The engine remained running, however pressing the gas pedal did nothing. This created an extremely dangerous situation as the traffic behind me was not aware my vehicle was slowing down and I had no ability to safely pull over to the side of the road. I brought the car to a stop, turned off the engine, waited a minute, and restarted it. At this point the gas pedal was functioning as expected, but the check engine light remained on. Went to the dealer, however they indicated the fix for the issue (technical service bulletin, #12-FL-004) had been applied after the 12/2012 incident and they found nothing new wrong this time. On 3/22/13, the exact same issue happened twice during one commute to work. The vehicle is currently at the dealer who has no idea why this is happening. This is a major safety issue and from other reports seen online, a recall should be investigated.

While traveling approx 55 mph, I hit a fairly significant pothole. The check engine light immediately came on and, at the very same instant, the gas pedal ceased to function. The engine remained running, however the gas pedal had no affect - e. G. Pressing the gas pedal did nothing. I immediately pulled onto the shoulder and brought the vehicle to a complete stop. The engine continued to idle and, after letting up on the brake, the vehicle moved forward on its own at approx 20 mph, more than expected under normal idle conditions. This condition lasted for approx 5 min until I could pull into a parking lot. I shut the engine off, waited a moment, then restarted it. At this point the gas pedal was functioning as expected, but the check engine light remained on. The vehicle was repaired at the dealer who notified me of an existing technical service bulletin, #12-FL-004, from Hyundai. They also indicated this was a "known issue" relating to the "ecm software.
