Two incident warnings on my dashboard saying of my back hatch was open when it was not. Had it serviced because the dash warning would not shut off. Service said it was fixed then happened again. Twice this happened intermittently. Another incident when on navigation screen, when the Navigator gave directions it changed to phone screen and went back to navigation screen when she stopped talking, like she was calling me to verbally give me directions! the most worrisome was as I was going 50 mph on city street, my gas peddle stopped engaging with the engine and I was loosing speed, as I pressed on the gas peddle harder the car was decreasing in speed as I watched the speedometer. During that incident all was working including brakes, radio and steering. I proceeded to drift into a driveway to stop the car for help, good thing I was not on the freeway could have gotten killed. The car is getting serviced now, I do not want it back, will trade in for different make/model is this considered a lemon and which laws/action do I take? I've only had the car only 7 months when this started to happen.

Leasing a 2019 GMC Terrain technical, within a few days climate off error came on while trying to turn on the ac or heat. Car safety features never alerted with sounds. Service bulletins pit 5663 and pic 6365A, GMC known problems before I signed my lease. Contacted GMC after penske Buick GMC, shillington pa, told me there was nothing they could do to fix the climate off error. Pushed an update through to fix the safety no alert sounds. At this point penske as well as GMC have no idea when the climate off errors will be fixed. I continue to pay my full lease rate for a vehicle that does not fully work.

When trying to start vehicle with push button ignition and brake pedal depressed, the vehicle failed to start. The dash lights would come on and error messages such as low battery came up on dash display. Vehicle was purchased on 11/17/18. Two separate occasions occurred where the car had to be jumped. One on 11/21/18 and 11/22/18. Unsure if an electrical wiring issue or battery issue?
