NHTSA complaint #11493398

Owner complaint summary

When driving at high speed on the highway, I have had instances of both FCW and/or AEB activating when there was no vehicle in front of me. This tends to happen without known cause and while I take the same route every day on my commute, the issue does not always occur. When FCW initiates with a large flashing BRAKE warning on the dash and loud beeping while at highway speeds, I am startled and second guess myself that I am not seeing something I am about to impact with. This creates confusion and can lead to making a maneuver or my braking in error which can cause a crash. This issue has occured numerous times and in speaking with other owners of the same vehicle, they have witnessed the same issue. I have also had AEB initiate at least twice while at highway speeds when there was no vehicle in front of me. This is the most frightening and dangerous issue that I've experienced in any vehicle I have driven. As with the above issue with FCW, there seems to be no way to reproduce the issue and it happens at random. While at highway speeds after receiving the FCW BRAKE warning, my vehicle instantaneously began emergency braking with no vehicle in front of me. This issue is unacceptable and can cause a serious crash on the highway. I speculate that these issues both may be caused by overhead highway signs or bridges but does not seem to occur in error consistently, even when driving the same route. I worry that these issues will cause myself or my family to be seriously injured due to failing safety technology and I have considered disabling these features in my vehicle. These issues have not been inspected nor verified independently as I have felt the issue is unresolvable based on feedback I have heard. At this point I consider myself lucky for not having been in a crash due to these systems failing.
