“Hello, I am requesting immediate attention to an issue with my vehicle that I believe is related to a factory defect. The recall service was completed, but the problem was not corrected. The warning lights are still illuminated on the instrument cluster, including ACC and LKAS. Since this issue appears to be related to a factory defect and the vehicle is still under warranty, I am requesting that the vehicle be properly diagnosed and repaired under the factory warranty at no cost to me. I am also concerned about the safety of operating the vehicle while these warning lights remain on. Please document this concern on the repair order and provide me with a clear explanation of the cause and the repairs needed. Please treat this as an urgent warranty repair request.”

“I was driving on the freeway at freeway speed with my Mom and daughter in the car and all of a sudden the car decelerated suddenly to almost a stop, sending us all flying forward. I felt like we had to have hit something, but we didn't; it just felt that way because of the sudden, abrupt stop while going freeway speed. Our bodies are sore this morning as a result. Thankfully, no one was directly behind me at the time, and we didn't get rear-ended. This could have definitely caused fatalities. If I were to have been killed, no one would have known it was a vehicle malfunction. They would have thought I braked hard for some unknown reason. Even if I braked hard, it wouldn't have caused such an impact; this felt like we hit a wall because the wheels seemed to just lock. Very frightening. I'll probably have to take my Mom to get looked over by a doctor due to the flying forward. Her seat belt flung her back, but for elderly people, it could cause some damage. It took me a moment to realize what happened.”

“I was driving on 42 at 2:05 a.m. And I was heading towards the exit to get off and I started slowing down and after I took my foot off the brake, the brake light illuminated on my dashboard for me to hit the break, like something was in front of me and there wasn’t anything in front of me.”

“I was driving on route 42 at 11:52 PM and my brake light illuminated on my dashboard indicating me to hit the brake so I stepped on the break so my car wouldn't brake itself. There was nothing directly in front of me for that like to come on but it did. The highway was dry there was a little bit of cars on the highway but in front of me”
