Was driving and tire pressure sensor warning came on and was showing I was losing pressure so slowed down in time where the tire was completely flat. Valve stem was cracked and broke off. Took in to get fixed and he found that two others were cracked so they could go bad as well. Luckily was not on highway when tire deflated.

Driving along at approx. 25mph and transmission suddenly lost power. The car was turned off and on randomly to apply power to the transmission for a couple of minutes to drive it back home. Thank god I had just left home! never, ever received a notice from GMC nor the dealer regarding power train problems. The car has been sitting since then (now going on approx 8 mos. Because I have not been able to afford approx. $3,500 for a new transmission. The saddest part... I don't even have a notification as to where to take it to get repaired.

Power steering stops working for 5 to 10 seconds after making a turn through water often no more than a few inches in depth. Usually occurs during or after rain, when water has accumulated at intersection corners or resident/business entrances. When this occurs, it becomes almost impossible to change the direction the vehicle is traveling in and has almost resulted in an accident twice so far.
