“Unexpected braking at highway speeds. This has at least 50 times at highway speeds. The truck has experienced repeated false Forward Collision Alerts and un-commanded Automatic Emergency Braking events. Adaptive Cruise Control frequently detects roadside objects and vehicles in adjacent lanes, particularly on curves. The vehicle has never had windshield replacement, front-end damage, suspension modifications, or aftermarket accessories. This is creating a safety hazard because the truck brakes unexpectedly in traffic at any speed.”Owner report · Forward Collision Avoidance · Jun 2026
“The tailgate opens unexpectedly, it can be inspected but it is in for repairs on 6/15/26. There was luggage in the back and it could have fallen out on the freeway.
