NHTSA complaint #11442690

Owner complaint summary

Forward collision avoidance system triggered 4 separate times in a 70 minute/60 mile drive on a stretch of highway and rural roads. The highway consists of 40 miles of divided and undivided highway, with up to 2 lanes per side. Occasionally, the undivided section has center turning lanes. Junctions and turnoffs are common. 3 incidents of forward collision detection automatic braking were triggered by semi trucks in the oncoming lanes on 1 lane per side undivided highway. The vehicle automatically applied the brakes, taking the vehicle from roughly 60mph to 30mph quickly during each instance. The trucks were not particularly close, nor were they appearing to leave their lane into mine. The 4th automatic braking incident occurred seemingly randomly on a rural, undivided 1 lane per side state road. All of these had the potential to cause an accident if I were being closely followed. All incidents occurred using the Autopilot cruise control feature. The auto steer lane keeping feature was activated for at least 1 of the 1st 3 events, but I do not recall which. In all of these instances, the vehicle did not perform any other evasive maneuvers. The 1st, 2nd, and 4th incidents were completely unexpected. The 3rd occurred during a particularly narrow, curvy section of undivided highway, which we were actively anticipating. Due to a configuration issue, the onboard dashcam was not functioning during these events and no video of these events was recorded. This vehicle is expected to go into the service center late December for this and other trim quality issues. Customer service indicated interest in these events and advised me to file bug reports when these occur. For issues with lane keeping, the autopilot auto steer feature regularly under-steered during most curves (narrow canyon driving) and often strayed closer to the lanes to the left of me than I would under my control.
