What 40 owners told NHTSA about the 2023 Subaru Ascent

On July 3, 2026, I was operating my vehicle heading Pocono PA, on I-80 in Pennsylvania. At approximately mile point 142.4, the vehicle's onboard Forward Collision Avoidance System (FCAS) suddenly and unexpectedly activated without any obstruction, hazard, or vehicle ahead. The abrupt, automated braking and system intervention caused an immediate loss of vehicle control, forcing the car into a 180-degree spin. The violent shift in momentum caused the vehicle to roll over on the highway before coming to a stop. No other vehicles were involved in the initiation of the crash.

2023 Subaru Ascent, under manufacturer basic warranty. Factory OEM battery has repeatedly failed. Voltage drops below 11.5V in normal use. Three documented failures in six weeks. SAFETY INCIDENT: Vehicle died on a public street and became completely immobilized. Brake warning light activated. Vehicle would not move even after a jump start. Passengers had to exit in a live traffic lane. A second vehicle was used to transport a replacement battery. The original battery is in my possession and available for inspection. A subsequent failure occurred when the original battery was reinstalled for a manufacturer-required diagnostic. Vehicle again would not start. KNOWN DEFECT: Subaru TSB 07-213-22R (revised 03/28/24) covers the 2023-24 Ascent battery and acknowledges the factory specification as inadequate, directing dealers to replace the battery, tray, cover, and holding rod with higher-capacity parts. This TSB was not proactively applied to my vehicle. The dealer did not identify or disclose it at earlier service visits where the battery concern was reported and "could not be reproduced." No recall or proactive owner notification has been issued. Dealers are not applying the TSB preventively. A complaint is open with Subaru of America Customer Advocacy. The manufacturer has declined to reimburse the out-of-pocket emergency replacement and has required a dealer diagnostic that has been repeatedly blocked by manufacturer/dealer procedural requirements.

In 2024, 2025, and 2026, I have had 2 incidents in each year where the cruise control is set to 60 to 65 mph and the cruise control then accelerates the car past 100 mph. When this occurs, tapping the break does NOT disengage the cruise control. All 6 times I have had to slam the breaks to a full dead stop while the car tries to accelerate anyway. April 4, 2026 and April 14, 2026 are the most recent occurrences and all occurrences so far for this issue have been during a downhill road incline. The dealer has dismissed the problem every time and has been unable to fix or reproduce the problem on demand. The random frequency of this problem can easily lead to a significant accident for the driver or others in the vicinity. And the lack of resolution from the Subaru dealer has lead me to report the issue here in hopes that if this is occurring for other vehicles that the company takes an actual resolution to solve the issue in their cruise control function.

I was entering an intersection to make a left-hand turn. I was driving at a low speed. My foot was pressing the accelerator and the car entered the intersection. In the middle of the intersection, the car wheels suddenly stopped turning. There was nothing in front of the car. Cars behind me began honking since my car stopped suddenly and unexpectedly while I saw a notice displayed on the car messaging, but I do not know what it said. I am unsure if the car engine turned off or not, but I remember turning on my hazard lights, putting the car in park and pressing the start button. I was able to drive out of the intersection to a safe location and turned off the car engine. I restarted the car and drove immediately to the dealer where I purchased the car from for them to evaluate it. It is currently being submitted for diagnostics at the car dealer. I told them I would make this safety report while I waited.

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.

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.

The passenger-side mirror on my Ascent has been damaged and removed since March 2025. I paid for the part on April 8, 2025 and was told it would arrive in a few weeks. As of July 1, 2025, the part has been delayed until August. The mirror is critical for visibility and safe operation. My wife drives this car daily with our infant. Subaru has refused to provide a rental, and the car is unsafe. I’ve contacted Subaru Corporate with no resolution, despite my continued persistence in contacting them through visits to their dealership in Plano, TX and several emails.

Formal Complaint Summary (VIN: [XXX] ) I am submitting this formal complaint concerning a 2023 Subaru Ascent Onyx Edition Limited (VIN: [XXX] ), which continues to experience brake-related safety defects despite recall repairs and repeated service attempts during the warranty period. Subaru of America issued Service Bulletin 06-92-24 in July 2024, which extended warranty coverage and acknowledged systemic issues with front brake components—specifically brake pulsation, squealing, pedal softness, and vibration. Subaru developed new components and repair protocols to address these issues, including new rotors, tie bars, pad kits, and a revised installation process. In September 2024, I brought the vehicle to CMA’s Subaru of Winchester after experiencing symptoms covered under the recall. Subaru replaced all required recall components. However, the defect returned in March 2025, while driving from Indianapolis to Winchester, now worse than before—resulting in violent steering wheel vibration, loud grinding noises, and unsafe braking behavior, particularly during downhill braking. Instead of replacing the parts again, Subaru resurfaced the upgraded rotors—despite the bulletin’s warnings against doing so. This resurfacing served as a temporary patch, not a true fix, and failed to resolve the underlying safety issue. I have made 21 lease payments totaling $13,707.96 and paid a $6,000 down payment, totaling $19,707.96 in out-of-pocket costs. Subaru has offered only a $2,500 goodwill payment, which I rejected. Relief Requested: I am requesting a full reimbursement with buy back under Magnuson-Moss Warranty Act. Investigation to the reoccurring break issues despite being serviced for a recall. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am filing a formal complaint against Subaru of America regarding a safety defect in my 2023 Subaru Ascent (VIN: [XXX] ) and their failure to honor warranty and recall obligations. Subaru issued recall TSB 06-92-24 to address front brake vibration by replacing rotors and pads with upgraded parts. My vehicle received this repair in September 2024. Less than 9,000 miles later, the exact same symptoms returned—steering wheel shaking and brake pulsation. In April 2025, Subaru resurfaced the upgraded rotors instead of replacing them, violating their own TSB, which prohibits unnecessary resurfacing and mandates rotor replacement if runout exceeds 0.05 mm. An independent inspection dated April 9, 2025, confirmed: Left front rotor measures 29.0 mm with 0.5 mm runout (10x Subaru’s limit) Right front rotor also measures 29.0 mm Subaru’s dealership claimed the rotors were 30.09 mm and 29.50 mm—inaccurate and misleading Subaru returned the vehicle in an unsafe condition with documented brake system defects. Their customer service insists the vehicle is “operating as designed,” despite clear evidence to the contrary. I am requesting regulatory review and a full buyback or enforcement of proper warranty compliance. Photos, inspection documents, and invoices are available.

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.

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.

The vehicle is stated to get 20 MPG in the city, 26 MPG on the Highway and 22 MPG combined according to the monroney label that I have when I purchased the vehicle new in October 2023. I am only seeing about 15 -17. I drive mostly in the city. I took a highway trip once and got about 20 MPG after resetting the meter and a fresh fill up. I hear of other people in online forums getting a little better MPG but they have to drive it very carefully. Like never letting the RPM's get over 200, slow starts and coasting a lot. To me this is not normal driving. I am expecting at lease 20 MPG in the city with normal driving, not driving like an old grandma. So I believe that Subaru has misrepresented their information on the monroney label. I am ok with you inspecting the vehicle. no warming lights on indicating a problem.

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.

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.
