2023 Subaru Ascent Reliability Report

There was a SUDDEN and UNINTENDED acceleration without the driver input while braking to park going approximately 1 - 2 MPH. Our safety was at risk. The vehicle was not in our control. A police report was generated. Rather than stopping we crashed into the apartment building causing significant damage to both the apartment and our vehicle. There were no warnings, no automatic braking to avoid the collision, the air bags did not deploy. The total damages are still being determined by the dealer and insurance company.

unknown defects in some vehicles that could cause sudden and unintended acceleration without driver input Yes, our safety was at risk. The vehicle was clearly not in our control. A police report was generated. The car plowed through the garage no control to brake The damages are being inspected by insurance. There were no waring lights that I could see

(1) PASSENGER seat airbag status light has been and still is intermittent. This fact is documented with dated pics attached. (4/4/23 and 8/6/23) (2) When the passenger airbag light is off, the airbag will not deploy putting my wife at serious risk. (She is the usual occupant at 98 lbs and 5ft 3inch) (3) Problem/issue has been observed and confirmed by local dealer. (4) Manufacturer has been advised of the issue and three attempts at resolution. (calibrating, seat bottom replacement, and software updating), see attached last service report. Note comment: "V E H I C L E I S PERFORMING AS DESIGNED" (5) There are no other warnings, messages, or symptoms other than the light intermittency. (6) Additionally, we drove a loaner car from dealer while problem resolution was attempted. See pic dated June 5. This vehicle showed similar behavior with airbag light. Draw your own conclusions.

Tire blew out at 70 mph on interstate with no warning and no debris on roadway. (245/50R20). Police officer aided us after we changed the spare to re-enter interstate safely due to high traffic speed. Beginning of a road trip so bought a new tire when we found a town & shop disposed of destroyed tire though we do have a photo. Heavy traffic and difficult to get to shoulder safely as vehicle began fishtailing as we maneuvered onto the gravel shoulder. Extremely frightening. Had to put spare on next to cars flying by just next to the rear passenger tire that blew. Vehicle only 3 months old and with less than 10k miles.

On 7/16/2023 I was driving my 2023 Subaru Ascent on I-95 when the tire PSI warning alerted me to low tire pressure on my rear driver side tire (Falken 245/50/R20 - tires were on the vehicle when purchased in April 2023). I immediately turned on my hazard lights, lessened my speed, and carefully made my way to the shoulder hoping to exit the highway for assistance. The tire pressure dropped from 34 to 0 in a matter of seconds (I watched the PSI monitor in the dash display). I barely made it to the shoulder. A AAA technician [XXX] A-Z Towing) changed my tire and noted that the tire may be defective after inspecting the tire, given the sidewall damage and no other obvious tire damage to cause the flat and that I had less than 4k miles on the vehicle. Internet searches yielded a recall for my exact vehicle and tires, my exact experience with sudden loss of tire pressure; yet my VIN was not included in the recall. I am concerned that the recall is not expansive enough and there may be other vehicles with defective tires driving unaware because their VIN was not identified. The recall may need to be more expansive and inclusive. I have an appointment with Subaru Hunt Valley today and have been in contact with Subaru of America - case #[XXX] s far, Subaru is not acknowledging my experience as part of the recall. I am fearful to drive my new car in that I worry the other three tires will rupture spontaneously. This is not the safety I expected when purchasing a new Subaru. I was on I-95 traveling at 55mph in the rain in the second from left lane when the tire PSI alert sounded. Thankfully, I acted immediately out of an abundance of caution and concern, since there was no reason for my tire to suddenly lose pressure it was alarming. I could have caused an accident and have been severely injured. I do not feel safe driving my vehicle knowing it has three other tires susceptible to the same issue.

Falken ZIEX ZE001 A/S rear right tire. We were driving on the 14 freeway when suddenly the car began shaking and warning lights started going off. My husband kept the wheel steady and I saw our tire come off in a solid piece onto the freeway! We had not hit anything. We made it four lanes over to the right shoulder safely to see that we had no tire left! We waited for assistance and got the spare put on thank God as we had our child in car with us. We called our mechanic at Subaru and returned an hour to him to replace the tire. After several hours we drove past the same spot and the tire that had come Off was laying completely intact on the shoulder of freeway. No obvious cuts in it except it was off the wheel/rim. This is a brand new vehicle with just 2500 miles on it.

When crossing a bridge at 40 mph with wide open lanes and shoulders the vehicle on cruise control suddenly braked aggressively and came to a full stop in the middle of a state highway bridge. Conditions were daylight, headed towards sun, no shadows on bridge. The road surface was smooth asphalt. There were shoulders as wide as the active lanes. There was no warning and very little time for a driver reaction. This type of vehicle behavior will most certainly cause rear end collisions.

The contact owns a 2023 Subaru Ascent. The contact stated that the Eyesight system was intermittently inoperable. A message indicating that the Eyesight function was disabled was displayed. Additionally, the contact stated that the Eyesight icon turned from green to white with a line across. The vehicle was taken to the dealer, where the failure could not be replicated. The dealer advised the contact to keep records of occurrences of the failure. The contact followed the dealer's instructions. The contact stated that upon following up with the dealer, the dealer informed the contact that the regional field engineer had been notified of the failure and advised that there was no remedy to correct the failure. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 3,000.

Incident Description – Event 1 On August 28, 2025, at approximately 4:45 p.m. while driving on Sugar Ridge Road, my 2023 Subaru Ascent suddenly jerked violently into the left lane without warning while the EyeSight Driver Assist system was active. I had to take immediate corrective action to maintain control and avoid a head-on collision. This behavior has occurred on multiple occasions under similar circumstances. My husband has also experienced the same issue while driving, which demonstrates this is not an isolated event. Incident Description – Event 2 On multiple other occasions, while the EyeSight Driver Assist system was engaged, the vehicle veered dangerously close to a semi-truck traveling beside us. I had to react instantly to prevent sideswiping the truck, which could have resulted in a severe accident. We have noticed this behavior occurs nearly every time we are alongside a semi-truck on the highway.

Subaru Eyesight will turn off randomly while driving or while parked (turn the vehicle off, unlock the door, sit for a minute or two and when restarting the vehicle, eyesight indicator is orange - off. Example - getting fuel at a full service gas station. Yes the vehicle is available for inspection. Our safety is put at risk. Once Eyesight is off it will not reset/restart, so you are driving without the number one Subaru safety feature. We can reproduce the error. The Dealer just looked at the codes and said it was normal operation. We reported the error to Subaru Customer care and we have a case number. Subaru Customer care is going to contact the Dealer. There is a small red "i" indicator light in the dash that will light up after Eyesight fails. There are no warnings of the failure. We understand rain, snow and fog will impact Eyesight. We had a 2020 Subaru that Eyesight only shutdown when expected (heavy rain, snow, fog) and would restart once we were in the clear, but now we are told that sunlight and windshield condensation affects Eyesight's functionality. We were also told by Customer care that the cameras where changed on the 2023 Ascent model.

The warning lights on the car flashed and the car shut down. I was on the highway. I called 911 and they told me to quickly and safely exit the car. Less than a minute later, the engine combusted and the car was engulfed in flames.

Only 3500 miles on new 2023 Subaru ASCENT and it won"t start. I have had to give it a boost four times already, anytime I need to use it. I check to make sure there are no lights left on. Just staying parked from one day to the next and it won"t start. I have an appointment at the dealer service dept. at 1:45 pm o June 5th, 2023, for them to hopefully resolve the problem. I'll have to give it boost to start the car and drive 125 miles to the dealer. Hope the car makes it there. On your website, the 2019, 2020and 2021 models had a recall for the battery draining because of faulty wiring. We would think the manufacture Sabaru would have taken care of this problem on the newer models.

The heated seats do not heat. They are luke warm and you can barely feel any heat. I took the vehicle to my local Subaru dealer and they determined there was no issue. Was told the seats are not suppose to get hot. So what is the point of heated seats then? There are several online groups for Subaru where owner discuss issues with their vehicles and give advice. There are many customers who are complaining about the same thing. (Seat being luke warm). Then there are other customers who say their seats get super hot on the same model vehicle. I contacted Subaru of America, told them about the issue and the complaints in the online groups about the issue. They only advised me to go to a different dealer and be retested. Obviously in certain vehicles the heated seats are defective because some people say they are super hot and some say they barely get warm. I just can't get anyone at Subaru to admin there is an issue and take corrective action. I am ok with you inspecting the vehicle. no warming lights on indicating a problem. The vehicle was bought new October 2023 and the seats have always been this way. I feel that the seats are defective in some manner and that alone is a safety risk. All that energy that is suppose to be heating the seats and isn't has to be going somewhere and could lead to a fire or electrical shock.

Front passenger seat in Subaru Ascents do not have means of raising and lowering seat height. Consequently, shorter passengers are faced with either sitting very low in front passenger seat or having to use a pillow or cushion to raise them up on seat. Not sure how this can affect front passenger safety, but it is certainly something worthy of investigating. Subaru said that this feature is not available on their Ascents, but is available on their smaller and less expensive Outbacks.

I have owned the car new since July 1, 2023. About a month into ownership the TPMS light came on. My wife was close to a tire shop so they checked all the pressures and all were fine. The light started coming on with regularity, any drive over about 25 miles would trigger it 99% of the time and it would reset shortly. Took to dealer they saw the faults in memory but did not know why they were being set. Cleared and reset the modules. The light was back a few days later and then on September 10 and 11 was on full time so I set an appointment. By the time I got the dealer the light had cleared. they found similar codes but they were not useful. The dealer wanted me to agree to pay for diagnostics if the "warranty company" turned down the claim. The warranty company being Subaru of America. I declined to pay for a safety issue being diagnosed on a brand new car. I have notified Subaru of America of my concern and have not received a response at this time. Looking at the Subaru forums on-line it appears that this TPMS issue is quite widespread. It is also apparent that Subaru is not willing to fix its safety issues without my agreeing to pay as well.
