Subaru Legacy jerking problems

I drove into the parking lot of Walgreens, then drove around and pulled into a parking spot facing the south side of the building and put my foot on the brake to stop and park. Instead of stopping, the car suddenly lurched forward violently and slammed into the brick wall of the building. My wife called 911 since I told her my chest really hurt. When the police came, I told them my foot must have slipped off the brake and hit the accelerator, since I had no idea what else might have caused the car to accelerate like that. My wife drove the car home and then drove to the ER where the EMTs had taken me. A CT scan showed that I had a fractured sternum, since my chest hit the steering wheel full force after the air bags failed to deploy. I was in excruciating pain for a few weeks, and after I felt better, we submitted a claim to our insurance company. We then took our 2017 Subaru Legacy to a certified Subaru collision repair center. We were shocked to find that the car was totaled, since it was still drivable. Something kept bothering us about the crash, since EyeSight should have applied the brakes if I had accidentally accelerated and it detected a brick wall in front of our car. After some research, we stumbled on the information about the Class-Action Lawsuit that was just settled by Subaru for reports of Sudden Unintended Acceleration (SUA). The description of what happens with SUA was exactly what I experienced, but this was the first we had heard of it. We were never notified about the lawsuit, even though our VIN number shows our car was involved. Our Subaru dealership had all our contact information since we bought our Legacy from them and they have done all the maintenance work on it. Unfortunately, we released our car to Copart as part of our insurance settlement, so there’s no way to check the EDR data. PLEASE let others know about this major safety issue before anyone else is seriously injured!

During regular use of the radio and head unit, at times the touch screen or controls, dials, buttons will be unresponsive. The Android Auto software tends to malfunction and will randomly disconnect and the audio will blast, full volume at the driver with the inability to control the volume other than to pull over and turn the vehicle off or manually power down the radio. This has happened on several occasions and with young children in the car, it can damage hearing, cause traumatic injury OR if in motion the driver can become quickly surprised or distracted and jerk the steering wheel or react to the jump in sound level that could injury passengers, or other vehicles occupied that may be nearby. This seems to be an issue with the inability to control sound level between different modes. At times though, the car will start and the radio will be blank, or be unresponsive until the car is turned off and back on again.

As I pulled up behind a car that was stopped at a stop sign, I took my foot off the gas pedal, and put it on the brake pedal. The moment i put my foot on the brake pedal, my car surged forward. I had a moment to think, and I confirmed that my foot was on the brake pedal, I had felt the brakes trying to resist the surge. I put the car into neutral, and it jerked to a stop. No one was hurt, I stopped the car in time, but I wondered if this had happened in other settings, what danger it would have posed. This has previously occurred rarely and intermittently when, starting out on some cold mornings, i shifted from reverse to neutral to drive, when backing out of my driveway in the morning.The car surged forward and I had to be quick on pressing the brake pedal hard to get it to stop before hitting a mailbox post. No warning lights went on, in any of these incidents. I called a Subaru dealer, who said there had been no recall history re this uninitiated surge behavior.

A friend was trying to move the car from the street when it suddenly lurched and accelerated and hit a tree, and boulder, and another car. They had not stepped on the accelerator yet. She lost control of the car. It was totaled as per State Farm.

This 2011 Subaru Legacy would pull severely to the right when braking, nearly jerking the steering wheel out of the drivers hand. The car was taken to a private auto repair shop where it was found the motor cradle (part #50527AJ00B) was completed rusted out so the A-arm to the wheel was unstable. In trying to locate a new part, online and from local dealers, it was found the part was on backorder. We were number 142 in line to receive the part. There is obviously a severe and dangerous problem with this issue as a car would veer into the other lane or offroad when braking. Subaru corporate office was contacted and I was told I would have to take the vehicle to the Subaru dealer. This would require a tow so I decided to have the private auto repair shop fix it as it was also undriveable. This complaint is to bring attention to this as a safety issue. My grandchildren were transported in this vehicle and were at risk of serious injury or death because of this problem. I feel Subaru should notify other owners of this problem on this make and model to avoid risk of serious injury or death. I have a video of the car and tire that shows what was happening before I took it to the auto repair shop. I was unable to upload the video file but would like to get it sent for your review. I can be emailed at [email protected]. My phone number is (309) 696-8849. Daniel Brune

On May 16, 2023 I was driving a friend home. We were stopped at a red light and felt an impact. My friend said, "You've been hit." I went out to check. No one had hit the car. It had lurched forward while my foot was on the brake. On 6/1/23 I pulled out of a driveway, car was in drive, foot on brake, paused to set GPS, car lurched forward. I brought to the dealer. They said they drove it for seven miles and could not duplicate the problem. About a year prior, the car had also lurched, but at that time I was in drive doing approx 30 mph, and I used the brake to slow it back to my speed. At that time the dealer found some leak in the transmission and, I believe, changed a gasket. These problems are intermittent and did not register on the car's computer, according to the dealer. Have you had any such complaint? Is my car safe?

While at a red light, and with foot firmly on brake pedal, the car suddenly began to rev and lurched forward. All the dash indicator lights (Brake, Engine, Lane Departure, etc.) lit up. I was able to keep the car from hitting the vehicle in front of me and managed to put the car in "park" until the light turned green, at which point I put the car back in "drive," pulled into USPS parking lot, collected myself, then drove to my local mechanic (~.25 miles). Braking to turn into mechanic's location the vehicle again revved and was difficult to slow, but I managed to do so, park, and left for them to examine. Later, and on local mechanic's advice, drove (without incident) to Subaru dealer in Milford, NH to drop off for them to investigate amid recent trend in unanticipated acceleration problem and pending class action lawsuit.

I had a transmission failure on my 2016 Subaru Legacy and there were no warning signs before this incident occurred. I was on a road trip driving at highway speeds and suddenly without warning I heard a loud bang. Then the "at oil temp" light came on, then the "check engine light", smelled something burning and also felt some slipping in the transmission. I pulled over as soon as I could. I towed it to the nearest dealer and they diagnosed the problem as being a bad valve body based on the code "P0712: Transmission Temperature Sensor Circuit Low" without test driving the vehicle. The valve body was replaced. Since my car's mileage was outside the extended warranty for this issue, Subaru only contributed half the cost of the repair. After the completion of the repair, the dealer told me they heard loud transmission noises and they recommended that my transmission may have to be replaced I test drove the vehicle with the service manager, except for the noise, the car had no warning lights and the car was shifting smoothly and was reassured that the car would not stall. After leaving the dealership, I drove 25 miles before the car started jerking and violently shaking. Then at a stop light on a highway, the car stalled. When I press the accelerator, the engine would rev but the car would not move. The vehicle was towed home, my car still would not move when I pressed the accelerator and the check engine light came on. I towed it to my local dealer, they checked the vehicle and said the transmission had an internal failure and replaced the transmission. The bad transmission was sent back to Subaru per their policy. Subaru did a goodwill warranty repair that covered a significant portion of the cost. This sudden transmission failure was a huge safety risk to myself and others. I could have rear-ended both times my car stalled.

Sometimes as I'm coming to a stop, such as at a red light or a stop sign, just before I stop, the car lurches and then stalls. This is an automatic transmission car, but the best way I can think of to describe what is happening is it is acting as if it is a manual transmission, and when you come to a stop and don't press in the clutch. If this happens at an inopportune time, it could cause an accident. Possibly you're slowing down as you turn through an intersection and it lurches and stalls. You would then be stopped in the middle of the intersection. There are no warning lamps or messages before this happens.

The lane assistance feature almost made me hit a semi truck that had drifted over its lane. I moved to the left to allow for space, the lane assist function tried to turn me back into the semi truck I was driving over the lane to avoid. It failed to recognize a major hazard and in fact created a more dangerous situation for me. I had to jerk the wheel back to the left, fortunately it shut off and I was able to maintain control.
