Immediately upon making a sharp right turn into a parking spot, the car suddenly accelerated at a very fast pace without me pushing the gas pedal. My immediate reaction was to press on the brake, but it did not stop.

We discovered the problem by accident -- pulled out of our garage and there was a coolant puddle on the garage floor. No dashboard warnings, no overheat messages, no visible symptoms before that.
NHTSA ODI report, 2026-10-06
Cracked head cyclinder leaking. Unsafe to drive, coolant can leak into engine if not already. They are aware of it and extended a warranty for the issue in 2024. However people like me, my coolant didn't leak until this year 2026.

I bought the car Saturday. Four days later, I filled the tank at 2:00 pm for the first time. I then drove about 30 miles. When I arrived home at 5:00PM, I parked in the garage.
