Owner (Hyundai Tucson 2008 gls) Hyundai customer service and representative is the worse. My vehicle has been cutting off without any warning. I've taken my car to the dealer numerous time indicating the car cut-offs without warning. In addition, I took my car to the dealer in 2009 complaining about the cut-off and not picking up speed. The dealer ourisman Hyundai (laurel) service representative indicated there is a value that allows the air flow intake for the vehicle not opening up properly. Needless to say; they have done nothing. Again the vehicle went back in for check engine light and cutoff. Their explanation, the gas tank was not tight. In 2010 the vehicle cutoff with warning and now is cutting off without warning. To date the vehicle has cutoff without warning more than 10 times to include August 16, 2011 (speed 10 mph), August 17, 2011 (speed 15 mph), August 23, 2011 (speed 20 mph) and August 29, 2011, (speed 60 mph) without warning. Each time, I've taken the vehicle to the dealer; however they cannot replicate the problem. As I mentioned to them, the vehicle cut-offs when it wants to without warning. The cutoff without warning is an accident waiting to happen. The August 29, 2011(at 60 mph) 7:45am cut-off was fortunate the vehicle in the back did not rear end me. The vehicle cutoff, again on August 29, 2011 at 5:45 pm. The vehicle has been with the dealer each time, however they cannot duplication of locate the problem. However, they want me to pay to replace the mass air flow sensor with may not be the problem. The July incident was the first time. The vehicle is back at the dealer trying to determine the problem.
