Vehicle died in a busy intersection coming off the freeway. Light flashed that indicated it was an issue with the electronic throttle control. The safety of myself and others was put at risk due to the posted speed of the road and multiple lanes from 4 directions. I had to remain in my vehicle to make sure I was not hit by another vehicle and due to the vehicle issue, I was impeding traffic. Lithia Dodge of Grants Pass, OR stated they could not make an appt for the vehicle to get looked at for 2 weeks out, scheduled 8/22/25. Dealership seems to think this is not an issue with safety and this issue can occur while the vehicle is in motion which is a huge safety issue. No warning lights flashed before the first one indicating the vehicle would shut down/lose all power.
