The vehicle has stalled twice while driving up to speeds of 60 mph. There is no power, no gas, nothing. The second time it stalled I was in the caldecott tunnel, highway 24, berkeley ca. Driving at a speed of 60 mph. There is no place to pull over for safety. Thankfully the tunnel is on a downhill slope, and I was able to coast out of the tunnel and pull over to the side of the road. The tunnel is an extremely dangerous place for engine failure. The first time I experienced engine failure was on a two lane road outside of antioch, ca. At night driving by myself. It is an terrifying feeling to be driving at speeds of 55-60 mph and have the vehicle shut off completely. There is no warning. I have taken this vehicle in several times for service, whining timing chain, several times, and each time the vehicle was not repaired. Now with the engine stall problems I am very afraid that I or others driving with me as well as other vehicles on the road may injured or worse killed due to this major defect in this car. I babysit my grandchildren on a regular basis and fear for their safety as well. I tried contacting Hyundai at their 1800 number and there was no extension available to speak to someone in order to file a claim. Also after waiting 20 minutes to get through it sent me to voice mail. The car is now at Hyundai in concord, California waiting for service. I was without a car for one week the first time it was supposedly repaired after the first stall. Besides being fearful of my safety and the safety of others I will now have to go without a vehicle again for a length of time.

At approximatlely 50-60 mph the car has a engine miss. Car loses power that can last for a second or more. Problem is a intermittent one. I have had it to the dealer at least 5 times. They have replaced the computer and the mass air sensor but the problem still happens. It seems to happen more when the truck is under load ie: Going up a hill, passing.
