Driver assist on other 2500 years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2014, 2015, 2016, 2019, 2020, 2021, 2022, 2026.
What this problem usually is
These reports come from drivers whose assistance systems did something they didn't ask for. Adaptive cruise switches itself off, or brakes for a car that isn't there. Lane keeping tugs the wheel toward the line, or a "sensor blocked" message appears on a clear day. Because both systems can brake or steer, owners tend to file them as safety complaints, and NHTSA files them under speed control, lane departure or forward collision.
What got replaced
Owners who name the part that was replaced mention the software (4 reports).

“ABS and Traction Control light on . This cancels out cruise control also. Vehicle was repaired at 23562 miles and is out again at 32000 miles. I have been on dealers waiting list for over a month. The part used for the repair must have been defective also. W11aiting time for the repair is entirely too long. Antilock brakes are a safety concern and should be quickly fixed.”

“The ABS, traction control, cruise control and 4x4 no longer function. It started intermittently and now is constant. The vehicle is available for inspection. After a hard stop the abs wonât engage and I lost traction of the truck. There are two warning lamps that are on at all times (abs and traction control). It has been ongoing for almost 1 year and 10,000 miles or so.”

Should you keep driving it?
This page can't tell you that. 0 of 289 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
