Throttle fails to respond for a brief but serious amount of time. When pulling into traffic, instead of accelerating the engine remains at an idle and the car moves forward slowly. I push on the throttle trying to make it go. Then it takes hold and the car leaps forward. Safety: Normal power is delayed as the car moves into traffic. Oncoming traffic must slow to prevent an accident. The dealer where I purchased the car, Santa Monica, CA, tried to find error codes. Also removed the throttle valve to check that it wasn't somehow stuck. They drove the car briefly. They say they've done all they can. No warning lamps, messages, codes stored in the computer. Note that the throttle pedal signals the computer to work the engine throttle valve (so I'm told). Problem occurs about once a month. First time was when I took posession at the dealer's. I requested to recind my purchase but, because I didn't by the cancellation option ($250), they refused.

While car was in motion car just stalled. Upon reading recalls the maker of the fuel pump which produce these pumps has recalled other models. Denso and Subaru should check these other models and replace the known issue. Vehicle had to be towed for safety of myself and my son.

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.

On December 1, 2022, as I jockeyed my car out of my garage it accelerated as I tried to break and I slowly drove into a stack of boxes at the back of the garage. No damage and I was able to back out and continue my journey. My wife was in the car with me. I continued on my trip to North Carolina without incident. On Dec 5, 2022, on our return home I exited the highway in southern Pa. to get supper. After I entered the off ramp and then prepared to obey a yield sign, the car again accelerated despite my attempt to brake. I swerved to the right to avoid any traffic and the car did eventually stop. Again no damage. Subsequently we resumed our travel and arrived home with no further incident. On December 6, 2022, as I backed out of the garage again it accelerated as I tempted to brake. Fortunately no damage and the car did finally stop in the driveway. I called the dealer and drove the car in for a checkup. They found no problems and reported the car ran as designed. While in the service department they replaced the muffler, put in new spark plugs and replaced a wheel bearing. I have had no further problems since I picked up the car on December 12, 2022. The dealership was very cooperative but I wanted to issue this concern with your agency in case there have been other complaints of this nature. I drive my car with some anxiety that another incident may recur. Thank you for your review and anticipated response.

I have been stranded repeatedly by my subaru since it was purchased with drained batteries, no explanation from subaru. Safety issues arise from the stranding. There is a lawsuit now with subaru but they are not acutally fixing the cars? No warnings were given and I now have a unreliable vehicle with no proposed fix from the manufacturer.

I was pulling into a parking lot. The attendant told me to back our 2017 Outback into a spot running along a fence and row of trees. I pulled forward, put my foot on the brake to fully stop. I then moved from "drive" to "reverse". Immediately, the engine started to rev very loudly as if my foot was on the accelerator (it was not!). The accelerator seemingly went to the floor and within a few seconds our car was in reverse at high speed. The only thing that stopped us was a maple tree and fence that we hit - about 15-20 yards behind us. The backend of the car is pushed in, including into the cabin, the rear window shattered etc. The fence is destroyed and tree damaged. My spouse, in the passenger seat, experienced a minor concussion and we both ended up with severe whiplash. If it weren't for the tree we would have just kept going. We are waiting on State Farm claim adjustor to see the car. I did inform Subaru (where the car was towed) what happened; they didn't seem particularly interested. We did get a police report. Thankfully, no one was hit. There were no signs of any problem with the accelerator prior to this incident. I am now, however, aware of numerous complaints and suits in related cases.

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.

Car lost power and engine shut down while at freeway speed with 1/8 tank apparent remaining on the gas gauge and 60 miles remaining on the miles to go indicator. Added 1 gallon at roadside and car started immediately. Added an additional 15.5 gallons at a station 12 miles from point the engine shut down. This leaves between 2 and 2.5 gallons of unused fuel in the tank at the point the car shut down from fuel starvation.

Fuel gauge is inaccurate and does not show near empty when no usable fuel is left in the tank. We were driving to an event with slightly less than 1/4 of a tank of gas remaining when the vehicle ran out of fuel. Complete engine stall (no sputtering/etc. Before) at 70mph on the highway, requiring an emergency stop across several lanes of traffic. This is clearly a dangerous problem, and it seems several other 2017 outback owners have reported similar issues. It appears to be similar to the 2018 fuel gauge recall (wtw-82) but for 2017 vehicles. Unfortunately, I didn't think to take a picture of the fuel gauge, but was actually paying close attention as I had received the notification for subaru's wud-89 "distance-to-empty software update," so I knew the distance-to-empty indicator was wrong, but given the notice said nothing about the fuel gauge itself and only mentioned the dte software was incorrect, I made the natural assumption that the gauge itself was still at least remotely accurate.
