2017 Subaru Outback Speed Control & Cruise Problems

The contact owns a 2017 Subaru Outback. The contact stated that while driving at a slow speed, the brake pedal was depressed, but the vehicle experienced unintended acceleration. The contact lifted her foot off the brake pedal and then firmly depressed the brake pedal another time. The vehicle was able to come to a stop. The contact stated that prior to the failure, the vehicle had stalled while driving. There was no warning light illuminated. The vehicle was taken to an independent mechanic and the dealer, who were unable to duplicate the failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 129,000.

While in a parking lot moving at very slow rate speed the car suddenly accelerated on its own. I had just slowly turned within a parking lot in preparation to backing into a parking space. I had just removed my foot from the accelerator and the car was almost at a stop and I was about to brake and put the car into reverse when it suddenly and rapidly accelerated on its own. My foot was not touching the accelerator at the time (it was over, but not yet touching, the brake). The car felt as if someone had suddenly slammed on the accelerator, but my foot was not on the accelerator at the time. Luckily my foot was over the brake when the rapid unexpected acceleration occurred and also luckily there were no cars in front of me. I was able to immediately slam on the brake so that the car did not hit anything. Before I was able to brake, the car quickly lurched forward at a surprisingly rapid rate of speed for a short distance. Quick application of the brakes stopped the sudden and rapid forward movement of the car. I did not notice any warning lights or messages on the car. This could have been a very dangerous situation. If someone had been walking in front of the car, they would have been hit and potentially seriously injured. If there had been cars parked in front of the space I was about to back into, the car would have hit them and caused damage. This happened earlier today and I have not yet reported it to the dealer. No police or insurance personnel were involved as I managed to avoid an accident. The event occurred today, Wednesday December 3rd at about 11 am. There were no other witnesses. To my knowledge this is the first occurrence of this rapid unexpected acceleration for this car.

The contact owns a 2017 Subaru Outback. The contact stated that after driving onto the driveway and pressing the brake pedal to park, the vehicle suddenly experienced unintended acceleration, drove forward, and crashed into the garage door. The contact shifted to the reverse position and the vehicle drove in reverse but would not stop while pressing the brake pedal. Eventually, the contact was able to shift to the park position, and the vehicle was stopped. During the incident garage door was severely damaged along with the rear end of a classic vehicle parked inside the garage. No injuries were reported, and no police report was filed. The cause of the failure was not determined. The local dealer was notified of the incident. The manufacturer was not yet contacted. The failure mileage was 41,000.

12/13/24 Incident 1: I braked as I approached a stop sign, but instead the car accelerated, running the stop sign. 12/16/24 Incident 2: I braked to slow down to turn right, but instead the car accelerated. There were no prior warnings or indications of the problem.

I experienced sudden acceleration in downtown and almost hit three cars, caused me to run three red lights and almost hit pedestrians. I had the car, 2017 outback Subaru towed to the dealer and was told there are no recalls, but saw many problems listed on the NHTSA website. It was terrifying and still shakes me up when I think what could have happened. Subaru told me this was the first they have seen this and that I do not have the extended warranty and I would be held for the cost. I am beyond upset. They tried to have me pick up the car after finding nothing. I told them they are to keep it until they find the issue. I have a loaner from them.

The contact owns a 2017 Subaru Outback. The contact stated that the vehicle was shifted into reverse with the brake pedal depressed; however, the vehicle independently accelerated. The vehicle reversed quickly; however, the contact's wife was able to regain control of the vehicle. The contact's wife stated that the failure recurred while shifted into drive with the brake pedal depressed. The contact stated while driving under 5 MPH, the vehicle independently accelerated forward. The contact's wife stated that the second failure recurred. The dealer was not contacted. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 85,000.

accelerator dangerously increased and could not slow down. i pressed the ignition button(to kill the engine and was "jamming on the brakes to no avail. to my knowledge subaru has not recalled vehicles for these reasons. no warning lamps or other symptoms. my car traveled approximately 1/4 before it stopped. i took out a tree or trees knocked down a light pole which slowed me down, hit a utility trailer. owner of trailer estimated my speed at 40mph. i was driving approximately 20mph when it violently accelerated. she witnessed my ride.

My vehicle accelerated when I was at a red light. My foot was on the brake. It also accelerated when I was backing out of our driveway. This resulted in a type of “ lurching” motion. The incident at the red light happened once. The incidents while backing out happened 3 times. No warning light were displayed. The vehicle has not been inspected yet. My safety was at risk because it accelerated once when my foot was on the brake and excessively when I was slowly backing up.

Yesterday, I was accelerating at a reasonable rate from a stop. My Outback stopped responding to the accelerator pedal and kicked up to 3500-4000 rpm. My brakes could barely hold the vehicle back and it forced me to slip my transmission in and out of neutral to prevent a crash. I pulled over twice to restart the car, hoping to reset something and address the issue, but it was still present when I pulled into my driveway and stopped the car for the evening. This morning, I started the vehicle and to my surprise, it started normally. I took it to my local mechanic who checked for codes or lights ( and carpets on the accelerator, etc,) and there were none. He also went under the hood and checked air filters and the entire intake system and found nothing. This is the third time I have experienced this issue. The first time I was making a right hand turn into a parking lot. I restarted the car and the issue went away. The second time it lasted a little longer but also was resolved by restarting the car. This third time, I was also making a right turn, but this time from a parking lot to the road, where I continued to drive. Two attempts at restarting did not resolve and it remained in this out-of-control condition until I turned it off.

I was driving my 2017 Subaru Outback on a trip from New York to Florida. On I-95 in heavy traffic I hit a bump in the road, and at that instant, nearly every warning light on my dash came on, including EyeSight, lane departure, and emergency braking. My adaptive cruise immediately disengaged causing the vehicle to suddenly slow (this incident was at highway speed). The "brake" light was also illuminated. Not knowing what happened, I pulled over on the side of the highway and found that the wire to the electric parking brake on the passenger side had disconnected from the brake module. I tried to plug it back in, but it would not stay. I secured the cable with a hair tie and continued on the trip. Approximately 500 miles later, I hit another bump or pothole, and the same thing happened. I checked under the car again, and discovered that the driver side had failed in the same manner. I secured the cable with another hair tie and was able to complete my trip. When I returned home, I discovered that this is a known issue and there is a Subaru TSB published, 06-63-18R. There is no warranty on this issue, and I was charged nearly $750 to fix a KNOWN PROBLEM caused by a plastic retainer. In my opinion, this issue should be treated as a safety defect and subject to a recall to replace with the newer part. Having all of your vehicle assists suddenly fail at highway speed in heavy traffic is a disconcerting and dangerous event.

On 2/13/22 I started my vehicle to move it back into the garage. Upon putting it into 'Drive' the engine unexpectedly started to ramp up the RPMs accelerating the vehicle forward. Fortunately I had my foot on the break slowing the progression and I was able to switch the gear to 'Neutral'. At that point the engine began to continue to ramp up the RPMs. I tried depressing and releasing the accelerator to see if the engine would respond and decrease the RPMS, it did not. I then switched off the engine to keep it from accelerating/increasing the RPMs. About five minutes after the initial incident I started the vehicle. Immediately upon startup the vehicle RPMs starting to ramp up. I tired depressing and releasing the accelerator to see if the engine would respond and decrease the RPMS, it did not. I then switched off the engine to keep it from accelerating/increasing the RPMs. After another five minutes I started the vehicle again. This time I let the car warmup for a minute before placing it into gear. During this time I did not experience another incident.

1) the car accelerated without any change in my driving. My car is available for inspection. 2) My safety and the car in front of me were at risk since the car was accelerating and removing my foot from the gas didn't reduce the speed. 3&4) I haven't had the car inspected by anyone and it can't be reproduced. 5) There were no warning signs. My car is well maintained and I follow manufacture recommendations for maintenance. The first time it happened was in the morning on my way to work in Phoenix, AZ going the speed limit, when it accelerated and removing my foot from the gas didn't reduce the speed. My first thought was I was going to smash into the car in front of me at full speed. Luckily, my brakes did work and I didn't hit the car that was quickly approaching. The second time it happened, it was early morning in Chandler, AZ, I was going the speed limit and the car accelerated as I was taking the onramp for the freeway. Once again the only way to get the car out of the accelerated mode was to hit the brakes. It has not occurred again within the last 3 weeks.

I WAS IN MOTION AND APPROACHING A RED LIGHT, AND AS I BEGAN TO LIGHTLY APPLY MY BRAKES TO SLOW DOWN, MY VEHICLE TRIED TO ACCELERATE (THERE WAS ALSO A CORRESPONDING REV IN THE ENGINE). FORTUNATELY, I WAS ABLE TO PRESS ON THE BRAKE PEDAL EXTRA HARD TO BRING IT TO A COMPLETE STOP.

IF IT'S RAINING OUTSIDE SOMETIMES THE CRUIS CONTROL WILL CUT OUT

THE CAR ACCELERATES WHEN BRAKING. ONLY HAPPENED TWICE SO FAR. DON'T REMEMBER EXACTLY WHERE OR WHAT I WAS DOING BUT FOR SURE NEEDED TO SLOW DOWN & AS I BRAKED THE CAR ALSO ACCELERATED AT THE SAME TIME. I DON'T REMEMBER THE DATES. IT'S BEEN AWHILE AGO. *TR

CAR STALLED (4X'S AT LEAST) WHEN MAKING TURNS; STALLED AFTER PASSING A CAR WHEN I RETURNED TO MY LANE WITH HIGH SPEED TRAFFIC BEHIND ME. HAVE HAD THIS PROBLEM SINCE WE PURCHASED CAR. HAVE TAKEN TO DEALER SEVERAL TIMES, EACH TIME THE RESULT WAS "THEY COULDN'T DUPLICATE PROBLEM", ONCE THEY SAID THEY ADJUSTED THE SOFTWARE TO CORRECT PROBLEM, RESULT DIDN'T SEEM TO IMPROVE.

YESTERDAY MORNING, I STOPPED MY SUBARU IN ORDER TO BACK INTO A PARKING SPACE. THE CAR WAS IN DRIVE AND MY FOOT WAS ON THE BRAKE. WHILE MY FOOT WAS STILL ON THE BRAKE AND I WAS CHANGING GEARS FROM DRIVE TO REVERSE, THE ENGINE STARTED ACCELERATING FULL-THROTTLE. I HAD TO PRESS THE BRAKE PEDAL VERY HARD TO PREVENT THE CAR FROM GOING DOWN THE HILLSIDE BEHIND THE PARKING LOT. I PUT THE CAR BACK IN PARK WITH THE ENGINE REVVING FULL-THROTTLE AND TURNED THE IGNITION OFF. AFTER THIS INCIDENT THE CAR OPERATED NORMALLY ' UNTIL TODAY. TODAY, MY CAR WAS PARKED IN MY DRIVEWAY IN FRONT OF MY GARAGE. WHEN I STARTED THE CAR EVERYTHING SEEMED FINE ' UNTIL, WITH MY FOOT ON THE BRAKE, I ATTEMPTED TO CHANGE GEARS FROM PARK TO DRIVE. AGAIN THE ENGINE IMMEDIATELY AND UNEXPECTEDLY ACCELERATED FULL-THROTTLE. AS I WAS MOVING THE GEAR SHIFTER FROM PARK TO REVERSE TO NEUTRAL TO DRIVE, I AGAIN HAD TO PRESS THE BRAKE PEDAL VERY HARD TO PREVENT THE CAR FROM BACKING INTO MY GARAGE DOOR. I IMMEDIATELY CALLED MY SUBARU DEALER BUT COULD NOT REACH THE SERVICE DEPARTMENT. AFTER 10-12 RINGS I GOT A MESSAGE INSTRUCTING ME TO LEAVE A MESSAGE FOR THEM TO CALL ME BACK SINCE THEY WERE CURRENTLY EXPERIENCING HEAVY CALL VOLUME DUE TO AN INCREASE IN RECALL ISSUES. I CALLED BACK AND GOT THROUGH TO SOMEONE IN THE SERVICE DEPARTMENT AND EXPLAINED THE PROBLEM TO THEM. THEY SAID THEY WERE UNFAMILIAR WITH THIS PROBLEM ON SUBARU OUTBACKS.

WAS SITTING AT A TRAFFIC LIGHT ON A CITY STREET, THE LIGHT TURNED GREEN AND I ACCELERATED THROUGH THE LIGHT AND AFTER 100-200 YARDS, THE CAR ACCELERATED WIDE-OPEN ON ITS OWN. I HIT ONE CAR ON THE RIGHT REAR AND REAR-ENDED ANOTHER WHICH STOPPED THE VEHICLE. ALL THE AIRBAGS DEPLOYED.

WHEN PULLING INTO A HEAD NO PRKING SPACE, THE ENGINE REVVED AND THE CAR SPED FORWARD SEVERAL FEET, HITTING A ROCK IN THE LAWN. I PUT THE CAR IN REVERSE AND THE SAME THING HAPPENED WITH CAR SPEEDING UNTIL I COULD HIT THE BRAKE.

TL* THE CONTACT OWNS A 2017 SUBARU OUTBACK. WHILE PULLING INTO A PARKING SPACE AT A VERY SLOW SPEED, THE VEHICLE SUDDENLY ACCELERATED AND CRASHED INTO A POLE AND A SECOND VEHICLE. THERE WERE NO INJURIES AND A POLICE REPORT WAS FILED. THE VEHICLE WAS TOWED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER AND DEALER WERE NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 20,000.
