2025 Mazda CX-70: lane keeping assist jerks the wheel

Filed Jul 12, 2026 · Driver assistance · CA

Multiple instances while driving on the highway with cruise control and lane keep assist on - on a bend slight turn the car veered into the other lane across the lane lines - even with other cars present. Additionally, it does not auto steer away from a blind spot collision - had I not noticed the car there would have been an accident.

Lane assist system acts on it's own and attempts to override my input. It can be very jarring especially at high speeds. I notice the issue mostly when I'm on the highway/freeway and attempting to lane change or take an exit ramp. The system trys to correct my steering and I have to briefly fight against it to maintain control.

I purchased a Certified Pre-Owned Mazda CX-70 that exhibits intermittent and unpredictable steering behavior, creating a significant safety concern. The steering will intermittently stiffen and then pull the vehicle left or right without driver input, at times toward oncoming traffic or the breakdown lane, requiring immediate correction. On straight roads, the vehicle does not consistently track and will drift unpredictably. When driving over minor road variations (such as small bumps or frost heaves), the steering wheel may jerk suddenly in the opposite direction. The vehicle also intermittently behaves as though lane-keeping assistance is active—auto-correcting relative to lane lines—despite all lane assist features being turned off. In multiple instances, the vehicle has tracked erratically along lane lines or navigated slight curves without driver input. The issue occurs unpredictably but is more pronounced on rural or uneven roads and during initial driving, though it can persist on highways as well. The issue caused several near miss accidents-twice it sent my vehicle careening into oncoming traffic; another time it tried to drive me back toward a pedestrian I was driving around intentionally. Driver has to be at constant heightened attention to avoid accident. Multiple repair attempts were made, including replacement of the steering column. The condition temporarily improved but returned and worsened. During the final repair attempt, dealership foreman, master technicians, and manufacturer technical support were involved, and the condition was ultimately deemed a “characteristic” with no repair available. The vehicle remains unrepaired and unsafe to operate. The dealer is refusing to supply the customer with any details of the repair order and diagnostic work that was done. The manufacturer has agreed to repurchase the vehicle under lemon law, confirming the defect could not be resolved.

While traveling eastbound on GA-20, I signaled to change lanes with my hands in the 9 and 3 position. I don't hold the wheel in a death grip like some people do, as I am confident with my vehicle and my skills. As I am changing lanes at 62 mph the car jerked the wheel to the right while flashing a warning that I need to hold the wheel. This has happened multiple times even though I am in complete control of the vehicle and very comfortable with my hand position. The car should NEVER jerk the wheel like that unexpectedly. I have lane departure turned off for this reason.

While attempting to change lanes on I-75 southbound, one lane to the left of my current position, I was enforced and the steering wheel pulled back to the right. I was navigating a right-hand curve on the interstate and moving past slower traffic at 81 mph. My turn signal was activated, the lane departure system deactivated, and the signal was still flashing as the lane change was executed. The turn signal should suspend enforcement as well as the system being deactivated. Both interlocks failed to operate. No other vehicles in the area would've contributed to this event. The lane departure "off" warning light was on the dash, indicating that the system was not operational. I was not firmly holding the wheel and allowing it to glide effortlessly through the lane change to execute my plan when it jerked back to the right.
