“Summary of Reported Behaviors Lurching: Commonly reported, often deemed a software/adaptive issue.

When I put into Drive the car lurched forward aggressively. I immediately applied the brakes and they pulsated but did not stop the car. My car continued moving forward across the parking lot and right over a large railroad tie. I am very afraid of driving the car. …”
NHTSA complaint #11719934, filed 2026-02“Parked my car at home at 3pm on 11/20/25. At 3:07 my neighbor banged on my front door & told me my car is on fire. The fire was under the hood with flames emerging in front of the windshield. Called 911 as we got to safety. Within minutes, the car was engulfed in flames & we watched as it went up in flames, with popping sounds, glass breaking, alarms going off, & the siding melting off the house, etc until the FD got there. They put out the fire, & checked the home- the car was a total loss, & the front of the house needed major repairs. …”
