Complaints on fileComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Incident Summary: I am reporting a recurring and dangerous failure of the vehicle’s lane-keeping/automated steering system. The vehicle provides unprompted, forceful steering inputs that fight the driver’s control, creating an immediate risk of high-speed collisions. Incident 1 (I-5 North): Traveling at 70 mph in the right-hand lane. Every few minutes, the vehicle initiated an unprompted steer to the left. I had to physically fight the steering wheel to maintain center and avoid a crash. The behavior only ceased when I moved to the left-hand lane. Incident 2 (I-80 East, Reno/Mogul, NV): Traveling at 65 mph in the left-hand lane. The vehicle initiated a sudden, forceful steer to the right, nearly causing a side-swipe collision with an adjacent vehicle. I had to use significant physical force to override the system and prevent an accident. Systemic Failure & Safety Concern: There is currently no way to permanently disable this system in the vehicle settings. Because the system defaults to "ON" upon every ignition cycle, I am forced to drive a vehicle that unpredictably attempts to steer into other lanes or off the road. The inability to permanently opt out of this malfunctioning "safety" feature is a grave concern, as the system itself has become the primary collision hazard.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
