Typical collision avoidance system symptoms owners report

  • Drivers report the system falsely detecting an obstacle and abruptly cutting speed from highway speed to near-crawl with no vehicle, debris, or object actually present.
  • Owners describe the rear cross traffic alert failing to produce an audible or visible warning when a car approaches from the side while backing up.
  • Some report the automatic emergency braking activating on its own during normal driving, sometimes triggered by roadside signs, trees while turning, or nothing identifiable, in one case bringing the vehicle to a complete stop at 40 mph.
  • Several owners say the system engages while pulling into a garage or parking space, slamming on the brakes repeatedly and creating a near rear-end collision risk.
  • One owner reported that after a wheel alignment, a technician could not recalibrate the lane assist or related safety features.
