While on a long road trip on a hot day, on the interstate, the car suddenly lost speed and would not accelerate. It was like the car had shifted into neutral. I was coasting on the interstate, steadily slowing, and was forced to pull over to the shoulder. I turned the car off and waited a couple of minutes then turned the car back on. No error messages were displaying at that time. About 5-10 minutes later, I pulled over for a planned stop. My husband assumed driving responsibilities when we got back into the car. Upon trying to get back on the interstate, the car would not accelerate, and multiple errors error messages appeared, including: ""System Malfunction/Visit Your Dealer," "Check Engine/Visit Your Dealer," "Drive-Start Control Malfunction/Visit Your Dealer," "Secondary Collision Brake System Malfunction/Visit Your Dealer," and "Traction Control Turned Off." He pulled into a nearby parking lot where we had to have the car towed to the dealership. It felt like the car was in neutral when this happened both times.

On Feb. 10th 2026 I was driving north I405 (Los Angeles). The car suddenly applied emergency breaks in the middle of the freeway, while there was no car in front of me, at least for 100m. I was lucky that the car behind me didn't hit me. It could be a serious multi-car collision.

When in cruise, the car will merge itself into the next lane if you hold the turn signal partially. If you keep holding it or fully engage the turn signal (maybe you forgot to turn off you signal, or held it too long), the car will merge through the solid white line off the road into a ditch. This happened to me once, and I noticed it trying several other times.
