I was driving about 55 mph with adaptive cruise control set to maintain a three-car-length following distance. It was raining, and when the vehicle in front of me slowed down, my vehicle did not detect it or slow down as expected. Instead, it continued accelerating, and I had to brake to avoid rear-ending the vehicle ahead.

This is a continuation for NHTSA campaign number 11711615. While an additional NHTSA complaint has been filed for the power train, this focuses specifically on design failures in the braking system. Our vehicle experienced a highway failure of the fuel pump, but due to the nature of a powertrain failure the car could not be put into neutral, only remain in park. The car was stranded in the middle of the road. As a AWD vehicle it similarly could not be towed as both wheels were fully locked. Tow informed us that there should be a manual release under the shifting column, however, this design safety feature had been removed in the 2024 iteration. The car was stuck on the road behind a blind turn on a somewhat busy road with vehicles typically traveling between 25-50 mph. The failure of a manual override for neutral and braking is a critical design failure that can lead to major accidents and death in the event of engine or transmission failure. There were no warnings, nor instructions or ability to get the car off the road.

My wife and I took our new vehicle on a 7k mile road trip this summer. Two times while on the freeway around 70 MPH, the sensors went wild. The cars auto break came on and red lights and collision warnings went off in the seat and the HUD. The vehicle slowed down to about 35 immediately! Then everything turned off and we sped back went down the road like nothing happened. Luckily there was no behind us or in front of us for a good distance. The thing is during both of the there was a car in the lane next to us at our 1 or 2 o'clock position. Perhaps the sensors. Mistakingly thought we were about to hit that car. Can these seniors be adjusted?
