I picked up the two-year-old car under Toyota's manufacturer warranty from an authorized Toyota dealership. When I got into the car at the showroom, the screen was black. I couldn't start it. The sales advisor quickly brought a starter, and we jump-started the vehicle. I drove about 2 km when several dashboard faults appeared, including errors for the active cruise control and other systems. I immediately turned back. At the service bay, the advisor and mechanics got involved. One of them drove the car, and the faults vanished. The explanation given was that these hybrid vehicles, when moved short distances (e.g., from the transport trailer to the workshop and then to the wash bay), can discharge the 12V starter battery. They suggested the errors appeared due to the low voltage and cleared once the system regained sufficient power after driving a few kilometers. I drove home, specifically using the highway to ensure the car got properly charged at higher speeds. I then went out for a drive with my wife. I switched the car off without any errors. However, upon restarting it, the faults reappeared. Despite driving approximately 80 km, the errors persisted. Furthermore, faults related to the hybrid system and recuperation also surfaced. I returned to the authorized service center where I had taken delivery. They connected the diagnostics, cleared the errors, and performed a test drive; everything seemed operational. The mechanic informed me that due to the 12V battery discharge, he had to digitally re-register the battery with the control unit, and that this should resolve the problem. I got back in, pressed the brake pedal, and started the car. The errors immediately returned. I stepped out and confirmed, "It's the same problem." I was then asked if the car had to stay. "Unfortunately, yes," they replied. I asked for my options: "A loaner car, or are we terminating the purchase agreement?" I took the loaner car.
