   There was a wreck up ahead, and two tow trucks with their emergency lights flashing were blocking the left two lanes. Traffic was stop-and-go due to the existing wreck. I was traveling in the lane to the right of the tow trucks as I approached. I stopped about 1–2 car lengths behind them. When traffic started to move, I began to move forward and advanced about a car length when the automatic emergency braking (AEB) activated and slammed on the brakes, even though the path in…

   While driving in a plaza parking lot at approximately 18mph the AEB engaged for no reason. There were not any objects near our car to activate the system. The AEB activated so quickly and abruptly that my spouse and I needed to seek medical attention due to whiplash.

   While driving, most often at dawn/dusk and commonly with cruise control engaged, the vehicle will falsely detect a vehicle ahead when none is present. It then triggers sudden Automatic Emergency Braking along with a crash/forward-collision indicator, causing an abrupt speed drop of 15–20 mph. This is a major safety concern for my family and me while commuting in our family vehicle. If a vehicle behind us follows too closely and does not brake as rapidly as this faulty…

   I was pulling out of my parents' driveway with my sister, who is almost 7 months pregnant in the passenger seat. Before we could get down the driveway, my car VIOLENTLY slammed itself into park to the point that I was convinced I had to have hit someone. No warnings no nothing, just WHAM, causing my lower back to feel tweaked now. After jumping out and seeing nothing, I immediately brought my car to the dealership for inspection. When I arrived, I was told that the sensors…

   This forward collision system will engage at inappropriate times when there is no crash concern. This vehicle has routinely engaged in a highway setting locking up the brakes and forcing the vehicle to a full stop on the highway with vehicles at speeds of 60+mph causing a grave safety risk and an immanent risk of serious injury or death from a serious highspeed crash. This software simply does not work and is not designed and programmed properly. It should not be on the road…

   My son was driving in stop and go traffic on I-95 and he rear-ended another car. No safety features activated: i.e. dash warning lights, audible noise, auto breaking. Last week I was at teh dealer for the recall that effected the Emergency Breaking system. Talking with the dealer some updated turns the auto system off, or otherwise adjust the settings that I have prior.

   Multiple safety-critical systems have malfunctioned since shortly after purchase, continuing to this day. The most serious is the forward collision braking, which has triggered randomly during normal driving. These braking events have occurred on highways and surface streets, posing a serious risk if a vehicle were following closely. During arbitration, the manufacturer admitted this is a known defect with no current fix, yet continues to return the vehicle marked as…

    After getting the recall repaired (which I was never informed of and I had the parking brake engage as I was travelling 30 mph causing me to skid down the road) I got the vehicle back and the very next day it was the same issue and the abs and traction control light came on and it began making loud clicking noises every time I would engage the brake.

    Windshield has terrible glare and reflects the dashboard as to limit visibility. Front collision and auto braking including rear collision and braking are a safety hazard as they create hard braking events for no reason. Car will stop sudden for no reason. These are both serious safety issues. These are problems we have had with the car since purchase and have had the dealership shop work on the problem and were told just to leave it turned off. This is not the correct way…
