Owner reports
Selected complaints filed with NHTSA by 2017 Subaru Outback owners, lightly cleaned up (personal details are redacted by NHTSA).
Wife was in a Collison on the freeway in Phoenix. She believes none of the collision avoidance devices worked properly to help prevent the accident. She heard no alarms or dings associated with the avoidance systems on her outback. She didn't feel the brakes lock up like they normally would. She feels if this truly is an issue, can she trust any of these safety features, which if working, could help avoid hitting everything from a person to a vehicle and injuring or killing her or someone else. We have not tried to reproduce this issue since the car is damaged and out our house. We have also not taken it to a dealer for the same reason. We did call Subaru and all they cared about was being sued. Which we said we did not want. We just wanted to make sure all systems are working or if there is an issue. They would not help or even offer to inspect the car. …
While attempting to park in a parking spot with a concrete parking lot stop the car experience an unintended acceleration and did not engage the safety braking system causing the car to jump over the concrete parking lot stops and hit a light lost and concrete supporting barrier behind the concrete parking lot stop. There were no warnings and this caused injury to the driver and passenger. A police report is being issued as well as contact with the car manufacturer. This is the second time this unintended accelerated occurred however this is the first incident where damage to the car and injury occurred,
was at a stop in the middle lane going to turn left, got hit straight head on by a driver driving in the middle lane. his air bags deployed, none of mine deployed. the front end and drivers side of the subaru was impacted
I experienced 2 incidences of sudden unexpected acceleration (SUA), the second one led to an explosive collision. Subaru asked that I sign the EDR release but refused to give me (rightful owner) a copy. With significant effort I obtained a copy of the EDR for myself. It is near impossible for the consumer to obtain their rightful copy, significant because it stinks of poor transparency for Subaru to investigate Subaru (see below). Once I obtained my copy, I released the EDR to Subaru and my vehicle was inspected by SOA at our local dealership. For some untold reason, the vehicle would "not to be released to me" at the end of the day but was held for additional time at the dealership. Later Customer "Advocacy" informed me that the results of the investigation was that the throttle was active 1.5 seconds prior to impact and that it was a case of "pedal misapplication". …
While driving at full speed on Interstate 80 through Sacramento CA while the outside temperature was 116 degrees, most of the more advanced systems of the car failed. I should have taken a picture of the control panel. I stopped the car and pulled out the user manual. Indicators illuminated included Eye Sight, Check Engine, tire pressure, and many many others. In fact, there were symbols on the dash that I could not find in the manual after extensive investigation. I attempted to drive the car after letting it cool down. The alerts persisted. I did check the tire pressure in all wheels and they were normal. The following day I checked the car in the morning (the temperature had subsided substantially) and the condition was still present. I made arrangements to go to the dealer, and upon getting into the car at about 2pm the indicators were all normal again. I did not go to the dealer. …
Car was being driven on the highway in cruise control, when the cruise control turned off and the car began to decelerate. When the gas pedal was pressed, the RPMs shot up but there was no acceleration. The car was pulled over, turned off, and we were not able to turn it on again. The car was towed to a shop, where they were able to identify the engine wasn't working but not the root cause, and also mentioned the possibility of there being a transmission problem. We then brought it to a Subaru dealer, and they said a similar thing without being able to diagnose anything more specific. This car is 8 years old and has had routine, consistent maintenance the entire time. The surprise of an engine failure with no warning is very alarming and dangerous.
The eyesight system not functioning and at this point has not been repaired and is available for inspection. Warning notices were intermittent with warning sound's coming on each time. Eventually the warnings came on nearly all the time. I was alone in the dark and very nervous. no other injury Yes the vehicle was taken to dealer, also I took photos as it continued to intermittently occur. Yes there were warning notices that alerted me. Note: dealer states non OEM windshield is cause , however windshield has been in vehicle fo nearly 2.5 years with no issue. Other electrical issue has occurred since eyesight issue.
Front windshield without warning had a stress crack appear on the passenger side from the top of the windshield to the middle. NO foreign item caused the damage. Again, the crack appeared without warning. My insurance company set up appointment with Safe Lite Auto Glass to replace the cracked windshield on August 2, 2022. The crack has now extended diagonally across the windshield as of Sunday July 31,2022. Because of the safety risk involved, I felt it was imperative to have it replaced ASAP. Plans are to reach out to the dealership on Monday August 1,2022 for their inspection and assessment.
received clean bill of health for battery after 10/24/19 service at dealership. AAA replaced battery on 10/31/19 when car would not start. Car would not start. Had to jump battery on 3/15/21. Car would not start. Had to jump battery on 6/20/21. Car would not start. Had to jump battery on 6/21/21. AAA replaced battery on 6/22/21 when car would not start. Blind spot monitoring turns itself off about 50% of the time. Repaired multiple times at dealership.
I was pulling into a space in a parking deck, foot on brake. Just as I was shifting into Park, the car lunged forward and slammed into the guard rail. Popped the fender and did some paint damage. Thankfully no one was hurt, but frightening to think that this could have happened in an intersection.
