My Shift To Park senor come on often and wouldn't let me turn the vehicle off. I have taken to dealership for repair. Long wait and because parts are back ordered due to numerous vehicles having this same problem. This has left me stranded in my vehicle and not able to turn it off and leave the vehicle. I feel this is unsafe and should be handled on a recall. I am now without a vehicle for who knows how long?

Vehicle has experienced multiple electrical and mechanical failures at unusually low mileage. Purchased at 32,000 miles. At approximately 50,000 miles, the factory radio/infotainment system failed completely. Electrical systems were observed remaining active after the vehicle was powered off, suggesting an underlying electrical fault. At approximately 60,000 miles, the power steering rack and fuel pump both required full replacement and were confirmed and replaced by an authorized dealership. No warning lights appeared prior to these failures — components failed without any prior indication. At approximately 100,000 miles, the transmission began failing and exhibits the known torque converter shudder issue widely reported on this vehicle platform. The shudder was present prior to full transmission failure symptoms appearing. The pattern of premature failures across multiple unrelated systems — electrical, steering, fuel delivery, and transmission — suggests a broader manufacturing defect.

When I’m driving a warning comes on my DIC screen that says “ACTION REQUIRED STEERING ASSIST IS REDUCED DRIVE WITH CARE”. The AC does not work and the temp gauge goes to cold with the radiator fan blowing at full speed. My car has done this since I purchased it used in 2019 and when I call dealer they say there is no recall and $1200-1800 to replace a sensor and thermostate. I have not had the issue fixed yet.
