What owners say about the forward collision avoidance
Verbatim from NHTSA complaints, newest first
“Gas cap was not secured overnight. The next day every ADAS function both safety and convenience was disabled and their lights were on. Users guide said car should recover after a few miles of driving. 100 miles and multiple restarts later it did not. It was taken to the dealer where they cleared the error for free. Poor design that a loose gas cap could cause a collision due to lack of ADAS. Dealer said it is a known condition with all Subaru models.”
“I was driving to a medical appointment in Ann Arbor Mi, and was in the area where [XXX] has a few big turns in the road .... like at ... [XXX] .All of he sudden the car started to accelerate a little on the turn so I attempted to brake the vehicle and I could not feel the brake pedal. I slowly moved into the right lane and frantically trying to slow the car down. I still could not feel the brake pedal and I believe when I hit the speed control off is when it slowed down and I was able to finally brake the car. It all happened in a matter of 10-20 seconds I would guess and it was absolutely terrifying. I have on occasion used the speed control to slow down the vehicle and wonder if that might have some connection.”
“The Subaru front camera incorrectly detected a hazard. The automatic braking system engaged and locked the steering. I skidded off the pavement, causing damage to the car. At the time of the accident, the blind sight warning lights flashed on the dash signaling that they were disabled. I was going very slow in a driveway. No personal damage just property damage and damage to the car. I have let the insurance company know about the issue and the collision center. I have had periodic instances where the warning signals of blind sight disabled have come on the vehicle. I informed Subaru in August 2024 about the issue at my last maintenance appointment. There is also a software update required on the vehicle. I asked Subaru to update the software in August 2024, but I was told by a service technician that it was not possible to update . I had to make a separate appointment for the software update as it took a long time.”
“After an automatic software download update, the RAB off light came on. The RAB light comes on when the car is put in Reverse and provides the option to turn that function off. After the update, the RAB icon is no longer displayed. It is the only system so far that I noticed that malfunctioned after the software update”
“On [XXX], I was driving east on [XXX] on the North side of Toledo Ohio close to the intersection with [XXX] . The "Check Engine" warning came on, all the vehicle "Eyesight" functions were automatically turned off, and Pre collision braking and Pre collision throttle control features were activated. There was no danger of a collision at this time, but all of this left me stranded in the middle of this busy four lane highway. I was able to literally crawl to the shoulder of the road. I was not hit, but it was just good fortune that prevented that. This is where my safety was at greatest risk. After about 10 minutes during which I started and stopped the car numerous times, the pre collision braking and throttle were deactivated and I was able to drive the car. I located the nearest Subaru dealer (Yark Subaru Toledo, Ohio) and drove there. The cause of the Check Engine light was diagnosed as a failure of the Thermal Control Valve. I had received a letter from Subaru dated May 1, 2024 stating that this part might fail and extending the warranty for this part. That letter specifically stated that nothing needed to be done until the part failed. There was no mention…”
“A small horizontal crack recently appeared on my Outback's front windshield while it was sitting in a garage overnight. The crack started from the passenger side and has now crept over to the middle of the windshield. Previous to this incident, the car had been sitting unused for over a month, so there was no opportunity for rocks or other debris from the road to cause the crack. This is the second time that the windshield has developed a crack out of thin air. I have replaced the windshield at least five times since owning the vehicle, in addition to having small chips from rocks repaired twice. These incidents are potentially dangerous and could possible interfere with the vehicle's automated systems such as collision detection and cameras.”
