2023 Subaru Ascent Problems

On XXX, I was operating my vehicle heading Pocono PA, on I-80 in [XXX]. 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.

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 am reporting two issues with my vehicle that I believe require further attention and repair assistance. I am requesting that both issues be properly repaired without any charges to me. There are no warning lights, error messages, or other dashboard warnings related to either issue. However, both conditions are abnormal and affecting the vehicle’s operation and ownership experience. 1. Steering Noise (Inside Cabin). The steering assembly inside the cabin. Whenever I make any type of turn, either left or right, I hear a noticeable clicking/clocking noise coming from inside the steering column area. I want to clarify that this noise is not coming from the wheels, tires, suspension, or steering components connected outside the cabin. The sound is specifically coming from the steering wheel/steering column area inside the vehicle. I have had this concern checked, and the only suggestion provided was to replace the suspected component. The dealer did not provide written confirmation of the diagnosis but verbally advised that they could replace the component and see if it resolves the issue. However, since there is no guarantee that the replacement will correct the problem, I do not feel comfortable spending my own money on a repair that has not been confirmed. I have also spoken with multiple third-party mechanics, and some have verbally indicated that this type of steering noise is a known issue that can occur after a few years and may be related to the clock spring (spiral cable/ribbon) or another internal steering column component. Because this appears to be a known manufacturer-related concern and not a result of misuse or neglect, I request that the issue be properly repaired at no cost. 2. Rear Brake Squeaking Noise. The rear brake pads and rotors are new, but the brakes continue to make a noticeable squeaking/squealing noise. The noise usually occurs after driving for some time, especially in warm weather when the brakes reach normal operating temperature.

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.

The windshield on the 2023 is extremely susceptible to cracking easily. Chips turn to cracks within minutes

2023 Subaru Ascent Touring. Front windshield easily cracked from minor rock strikes 3 times within 20 months. Replacement with Subarus OEM glasses twice already within 3 months. Now a new crack needs repair or potential replacement. Defective windshield that cannot withhold minor impact is clearly serious safety concern, increased stress on owner and burden on insurance, and impact to vehicle structural integrity for repeated replacements, and depreciation of vehicle value.

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

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.

The vehicle exhibited transmission slippage but did not provide any warning lights or other symptoms . About 100 miles later, the Automatic Transmission Oil light came on (flashing YELLOW), and all other systems light up (both Yellow and Red) disabling front collision, auto vehicle hold, RAB, etc. Pulled to a safe location and left in park for 10-15 minutes per guidance. Had towed to dealer to determine issue, transmission failure on a 3.5 yr old vehicle with 80,019 miles.

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.

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.

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.

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.

The auto brakes are not accurate because it triggers them in unsafe situations.
