Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“My vehicle is equipped with eyesight, which is a Subaru technology that includes adaptive cruise control, forward collison warning/breaking, lane departure warning, rear automatic braking, etc. Subaru claims that windshield replacements must use Subaru glass due the optical clarity of the windshield and that the eyesight system must be recalibrated. This is a $1339 cost (via safelight) to replace the windsheild. I have 8400 miles on my vehicle, and I am getting ready to have the second windshield put on the car. The glass simply breaks to easily. …”

“The lane keeping feature will randomly cause the vehicle to veer towards the center line at a variety of speeds and under a variety of conditions, requiring immediate driver correction to avoid crossing the center line. No accident has occurred but the system is now deactivated. In addition, the collision avoidance system does not reliably acquire a vehicle ahead if that vehicle is stopped and the speed differential is >30-40 MPH. Without driver manual braking, a crash would occur.”

“Was driving on highway when all of the lights on my dash illuminated. Eventually I got a warning for oil at temp alarm. Was giving code P2757 and P0700. Looks like this a common issue in Subarus but doesn’t look like it covers anything after 2020.”

NHTSA complaint #11754078, filed 2026-07

“Subaru Eyesight system engaged randomly with no forward obstacles. Dashboard lit up, signaled alarm, and brakes engaged causing the car's nose to bottom-out. This has happened twice, thankfully at low speeds and thankfully without another car rear ending me. I'm worried this will happen on the highway. Eyesight system is generally unreliable. Random lane departure warnings and obstacles detected where there are none.”

“The car in front of me was about a two car's lengths away. It was very cold and that car's exhaust plume was larger than normal. The exhaust plume was highlighted by sunlight, and I believe my car thought it was an object. The auto braking system alerted and immediately slammed on the brakes in the middle of heavy traffic. There was no time for me to respond. Thankfully no one hit me. If I'd been on the highway it could have been catastrophic. The problem has not been reproduced or inspected.”
