Please Help! 2006 Tucson Keeps Stalling-Dealer No Help

Hello,
 
I have a serious problem .I have a 2006 Tucson that keeps stalling when you are either slowing down or making a turn. All the dash lights come on and the vehicle stalls out. The car will sometimes surge or shakes before stalling and  you can feel the transmission downshift hard before it stalls.You can start the vehicle back up again after it stalls. The vehicle will stall at least 10 times a day. I've had the car to the dealer 6 times and  they told me ,well no codes come up so there's nothing wrong with the car. This is a very dangerous situation because sometimes my wife has our 3year old in the car with her when the car stalls and she lose's all steering. I'm afraid of an accident. The dealer is no help and can't correct the problem.
 
What could it be or what should I do?
 
Please any info would be appreciated
Thank You

Have you been able to repeat the symptoms for the dealer?  If so, there is no way they can say "there is nothing wrong with the car"!  Call the Hyundai Customer Service number in your owners manual.  Also, if there is one nearby, try a different dealer.
 
It sounds like a loose electrical connection.  On my Elantra there is a fuse in the engine compartment labeled "SNSR" that controls all the fuel and engine control sensors.  Make sure that fuse is in all the way.
 
Also, sometimes random stalling of a Hyundai can be due to a bad crankshaft position sensor.  If that sensor is bad, the engine shuts down but won't necessarily throw a code.

I had a similar problem with a previous car.  The problem was the lock-up converter was not unlocking so when it came to a stop, it would stall the engine.  The problem only happened if the converter locked up which only happens after sustained high gear driving.  Around town, the converter didn't lock so it would not stall but if I could get the converter to lock while driving, then when I stopped it stalled.

Make sure the dealer is getting your Tuscon up to speed high enough to lock the convreter and then have him stop.  If they are just driving around the block, the converter won't lock and the problem won't appear.

Tell them to check the Torque Converter Clutch solenoid (TCC).  Here are 2 TSB's that might help (there may be others):
TSB # 02-40-007
TSB # 05-40-006-2
