Forward Collision Avoidance 7 1 crash 2 injury

“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. INFORMATION REDACTED PURSUANT TO THE…”
NHTSA complaint #11749348, 2026 · crash · 2 injury(ies)

“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 pro…”

“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…”

Unknown Or Other 7 1 crash 2 injury

“I attempted to make a U-turn with the steering wheel fully turned to the left. When I accelerated, the car took off and went straight into the curb. It did so by “plowing” or what is referred to as severely undesteering - which forced the front right face of the wheel into the curb, breaking the wheel off. The vehicle continued accelerating for another 50 feet (as can be seen in the photographs) when the engine gradually and audibly died down and came to a stop. The brakes were no longer functioning properly at that time while sinking to the floor as they did immediately after the first impa…”

NHTSA complaint #11668559, 2025

“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.”
NHTSA complaint #11614676, 2024

“Windshield is delicate and very easily chipped. Windshield has three different chips from 4000 miles of paved road driving. Small chips have quickly spread into long cracks across the windshield.”

Tires 3

“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…”

“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 def…”

“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…”

Lane Departure 2

“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.

“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 h…”

Seats 2

“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 i…”

“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.”

Wheels 2

“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.…”
