Car Stall problems of the 2017 Chevrolet Tahoe

On Wednesday, July 12, 2017, I signed a lease for a brand-new 2017 Chevrolet Tahoe LS at ed bozarth Chevrolet in las vegas nv. Three days later as I was driving the vehicle on the main streets my vehicle kept hesitating and jumping as I would have to stop in traffic then move again when I pressed on the gas. Then as I was waiting to make a left turn in traffic, my vehicle stalled then allowed me to go. Then suddenly my engine light came on. I then received an email from the onstar notification stating the diagnostic detected an issue with my engine and my transmission system. I brought my vehicle in Monday 07/17/17 morning at 11 am. The service man informed me that this was a known issue with some of the brand-new vehicles by the dealership and general motors because of the excessive heat in las vegas, but there was no recall in place for general motors and a letter was issued dated June 30, 2017 that he had to provide to me because there was no solution to fix the problem at this time. He let me that general motors has not issued a recall because they don't know what to fix on the vehicle due to the extreme heat. I asked why was this not disclose to me before leasing me the vehicle if this was a known issue to allow me the choice to decide if this was something I could tolerate. The sales rep nor the service department were able to answer that question. I asked to speak to the general manager of ed bozarth Chevrolet and was informed that I would need to wait until Monday, July 24once he returns from vacation. I let the sales rep know that I was unhappy, I was deceived and I feel unsafe driving this vehicle. I have the dated copy of the letter #pip5507 stalling - hesitation, I have the first diagnostic email stating the vehicle was in perfect condition, and I have the diagnostic email from on star stating that the vehicle is having engine and transmission defects.
