My transmission keeps sticking when I shift into drive or reverse. Just a couple of days ago, it happened the worst it has ever done before. I shifted into reverse and my vehicle was completely stopped when I shifted. I began to let off of the brakes and gently push the accelerator to start moving back, my vehicle then punched itself into reverse. I felt after that incident, something had to have been damaged. I’m almost afraid to drive my vehicle after that. When my vehicle punched itself into reverse, I was literally jolted towards the steering wheel and thankfully my seatbelt caught me. Incidents with the the shifting into drive or reverse have happened before, but never nearly as intense. About a year ago, I brought my vehicle in to my local GMC Dealership for a concern with my transmission shifting weirdly and holding itself in gear at an unnecessarily high RPM speed. The technician stated to me, “with these 9-speeds, they tend to get confused at various speeds”. I asked him to elaborate and he could not. These issues have now gotten worse. With my suspension, every turn I take, I get a kreaking sound from my front driver side wheel well. It sounds as if my tire if going to break off. I’ve done visual inspections and nothing out of the ordinary is noticeable to the eye. My vehicle is a 2019 with less than 40,000 miles on it. I should not be having all of these issues. I’m genuinely concerned for my safety.
