2019 Subaru Crosstrek: lane keeping assist jerks the wheel

Filed Jul 28, 2026 · Transmission · TX

While driving, my dashboard warning lights on my 2019 Subaru Crosstrek—AT OIL TEMP, EyeSight, and Lane Assist—illuminated simultaneously with a sudden onset of transmission slippage and erratic shifting, with no prior warning symptoms. The vehicle experienced a sudden mechanical failure of the Continuously Variable Transmission (CVT) torque converter clutch solenoid valve, which was diagnosed and confirmed by an independent service center under diagnostic trouble codes P0971 and C1431. This sudden loss of reliable vehicle propulsion and disabling of active driver-assist safety systems created an immediate collision hazard, severely compromising driver control and vehicle safety in live traffic. Subaru is denying reimbursement for this known CVT defect, expecting consumers to foot the bill after relying on a single mail notification sent 13 months prior. Although the failed component was replaced during this emergency repair using genuine OEM parts supplied directly by an authorized Subaru dealership parts department, all diagnostic logs, itemized parts records, and repair documentation are attached.

My 2019 Subaru Crosstrek surges at speeds around 60 MPH, and swerves the vehicle without my control. I have to hold the steering wheel tightly and steer out of the swerve, which is incredibly dangerous on freeways or mountain roads. Apparently, the lane departure assist is the culprit, so now I have to disable the app before I drive. Why would I allow this dangerous application to drive my car for me? I have barely avoided crashing into semi trucks and driving into road shoulders because of this device. I think the car is dangerous. There is yet another dangerous issue with this car. There is another device that disables the transmission while idling in traffic. The steering and transmission are literally locked in place. I had this happen once in a drive through window, and once on a hill, while traffic was stopped for an accident. When the traffic started to move again, 20 minutes later, I could not get my car to start, and I was in front of a mile long line of traffic, coming back to highway speed, completely stopped. A policeman stopped and knew that there was a little " dimple" on my dashboard that would uncover a locking mechanism. If we only had a slender probe that would fit inside the dimple-pencil too big, so was screwdriver. By this time, I had 2 policemen stopped and traffic whizzing by me. An electrician stopped, knew about the dimple too, and had a slender enough rod to fit into the area, slid the locking mechanism to the side, and started the car again. On both of these issues, I called Subaru customer service and Subaru corporate. NOBODY knew what these issues were, never heard of them! The car is inherently dangerous and I am stuck driving it because I financed it only a year ago and can't afford to buy another car. Subaru should at least acknowledge these dangerous issues, and offer me another model without these issues. The 2019 Crosstrek is the model I have that has these dangerous issues. Earlier and later models do not.

The EyeSight turned off and would not turn back on. Then the airbag symbol lit up on the dashboard. My cruise control and lane assistance were not working as well. If I had been involved in an accident, the airbags would not have deployed. The warning messages appeared about 3 weeks ago.

I have this system in my toyota,it does not negatively effect steering wheel control.

When driving, especially at highway speeds, the steering will unexpectedly push the car across the lane, sometimes harshly, especially around curves. This is more than a simple nudge for lane assist, it scares the heck out of you as you fight the steering wheel to maintain control. At least on our car it's enough to cause an accident! The car has been in to subaru three times to correct this problem, without success. After informing subaru of america and opening a formal complaint (case #148267253025) they dismiss this as the eye sight/lane assist working, and say the remedy is to turn this safety feature off...which to us is ridiculous and not why we purchased this car. As we have informed subaru the car sits in our garage as we are simply too afraid to drive it. Our initial complaint was in july, after our first road trip,and the problem recurs irregularly and without warning. The car now has 5725 miles on the odometer.

Driving 70 MPH, cruise on but not set, lane keep assist was on. Driving down middle of my lane on the highway the car abruptly turns to the right. I could not recover fast enough to avoid going into the next lane. Because I was over the line, the lane departure gave me an alert. A few days later it happened for the 2nd time. Same speed, same abrupt force turning the car, this time to the left. I may have been close the the right side of my lane but nonetheless, it suppose to nudge the steering wheel back into my lane. Not an abrupt turn. It certainly gets your attention and could cause an accident.

The lane assist is sometimes overly aggressive, without warning. When taking an exit ramp to the right it once violently tried to correct to the left. In crosswinds it's like trying to steer a mario cart game and will jerk you back and forth in the lane.
