Air Conditioner problems of the 2014 Chevrolet Camaro

When I park my vehicle, shift into park, the key stays locked in the ignition. I have to turn the vehicle on and shift into drive or reverse and then shift into park again to release the key. This has happened before in 2016 and dealership fixed the problem after 4 times going to them. Unfortunately, the problem is occurring again. I've taken my vehicle to Chevrolet dealership and the problem is not occurring while it's there. My extended warranty is expiring soon and I still have this problem. Tomorrow, an inspector will be assessing my car. My vehicle has been in/out of the dealership a total of 5 days. . . Waiting to see what's wrong with it. The gas gauge doesn't move when the car is turned on. I have to turn it off then back on and the gas gauge moves. The air conditioner when I turned knob no air comes out. The screen say off/off and yet the knob is at full blast. I turn it back to the off position and then turn the knob to 7 and it continues to say off/off - no lights are on and no air comes out. I've given pictures to the service department and I'm waiting to see what the inspector says. It's a nuisance to have these problems. I'm thinking I bought a lemon car. Too many issues. . .

In June 2018 air conditioning briefly went out. Opened fuse box. Rust was surrounding area. Moved fuse and air started working again. Car has 27,300 miles currently. On July 29th 2018 I was driving 60-65 on freeway in medium traffic and gas pedal left my foot and went to the floor. Stuck. I am beating it with my foot trying to get it to release. I went up to speeds of 120+. 3-3/12 miles it released before I had to do evasive measures. I have been driving Camaros trans ams and corvettes since 1975. Never had this happen. Upon inspection the under the drivers dash is full of rust. Not surface rust. Old heavy rust. I have a 97 Camaro in the driveway that has none of what this 2014 has. Did or does that throttle system have water damaged wiring? I have had radio replaced and drivers side seat motor replaced. Is this a flood vehicle? it's not on the history but does that mean anything anymore? I've been told by four mechanics it's undrivable, unsafe. What did happen to this car?.
