The vehicle is a rental vehicle. It experienced two incidents of sudden loss of propulsion within the first two days of operation. During both events, the vehicle became completely unresponsive to accelerator pedal input and would not move despite being placed in Drive. I attempted to shift the vehicle into Park and then back into Drive, but propulsion was not restored. No warning lights, malfunction indicators, or system messages were displayed before or during the failure. The first incident occurred while exiting a car wash. The vehicle became immobilized in an active traffic lane and would not respond to throttle input, creating an immediate risk of rear-end collision. Vehicles were…

I did an OTA update that made the rear view camera work intermittently. It would just flash an image every couple of seconds instead of a live stream. I took it into the dealer, and on the way, it totally gave out in the middle of traffic in a very unsafe way. I was flashed with many warning signs and was not able to get it started again for 5min by just turning it on/off again. I finally got it to the dealer and after 6 weeks they told me that something spilled in the cup holders and fried the backup camera and drivetrain components. I find it extremely off the drivetrain and safety critical components are stored under a cup holder with no protection.

I have had the car since May 2023 and every winter moisture builds up on my windows on the inside of the car and over night it gets frozen from the inside. There is mold growing on the inside of the door panels, the back hatch window and under the seat and on the seat belts.

I pulled the vehicle out of my garage yesterday and drove it out and turned it around and put it in reverse to park it on a very slight incline on my driveway close to the garage to clean it, put it in park, and shut if off. I spent a couple hours vacuuming and cleaning it. I then went to turn it on to back it into my garage for the night and it lurched backwards in an alarming scary way - I rolled my passenger window down and asked my husband who was right there if there was something in the way that I had just tried to run over with my car. He assured me there was nothing in the way so I put the car in drive and tried to go forward and it did the same thing. It was like I was trying to go…
