POWER TRAIN
Every time I go out of park there is a massive clubking noise from under the car. It's actually a super common item with these cars I am seeing as well in other forums. I believe this could lead to sheared parking brakes in the future.

STRUCTURE:BODY
The windshield on the 2021 Subaru Ascent is dangerous because it chips extremely easily. I purchased the car new in 2021 and since then I have had 7 rock chips (in all different states (TX, CA, WA) and driving conditions/speeds/roads). In the 4 years since I have owned it I have had the windshield replaced twice so I am on my 3rd windshield. Each time the rock hits, it causes a large chip to form which distracts the driver momentarily. It also creates defects in the windshield which could lead to safety issues of the windshield shattering.

SERVICE BRAKES
Brakes shudder and fade when slowing down from highway speeds. Subaru has issued many "fixes" but it keeps happening. See most recent "Ascent Front Brake Warranty Extension Coverage" it still has not fixed the problem!

ELECTRICAL SYSTEM
Battery draining. Bought car from dealership preowned with 25k miles. Owned it for 3 weeks and so far -Battery dead, jumped it, good for a day then dead again. -took back to dealership, said bad battery, replaced it, good for a week and a half then dead again -scheduling to go to a subaru dealership for diagnoses Ive read about the DCM on these vehicles trying to connect to 3g towers continously even when the car is off. The 3g towers are no longer in use in the USA. Subaru should have a software update to remedy this issue but have not found that thus far. Just a lawsuit over this issue.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
I was driving along with no traffic in front of me and no oncoming traffic when the automatic braking system engaged with no vehicles in front of me, this was at 7:42 AM on Monday August 12, 2024. This was not the first time it had done this, but the first time I had the time and no traffic anywhere around to confuse the system. My concern is that if another car was following too closely they would have hit me since there was no reason for the emergency breaking system to engage.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The driver was driving into a parking lot preparing to park, when the vehicle accelerated and started going forward at a higher speed. The vehicle struck a parked vehicle, then travelled across the parking lot, over curbs, a grass median, landscaping, and struck a rock building at a high rate of speed, causing a partial collapse of the wall. The vehicle is available for inspection through the insurance company. No analysis of data was done and nothing was inspected. There were no symptoms of the problem beforehand. The vehicle has automatic emergency braking, but it evidently didn't operate. It is unknown if this was caused by driver error in accelerating and never braking.

SERVICE BRAKES
Brake rotors, front and back warp. Rotors have been replaced and resurfaced multiple times. The vehicle is over-sized for the braking hardware included with the vehicle. I have spoken to the dealer multiple times and they are aware of the undersized brake component issue across this model line. Although promised, Subaru has not addressed the issue and it is a safety hazard in hilly terrain.

SERVICE BRAKES
Started having problems with the brand new car shaking and brakes making grinding noises when stopping around 20K miles. Brought the car to the dealership and they ended up replacing the brake pads and rotors. It’s been just over a year and less than 15K miles since the replacement and the car started shaking and brakes are making a grinding noise again. Again took the car to the dealership and the rotors are bad. After further research, this is a constant and known issue and has yet to be resolved by Subaru. Instead they wait for the new car warranty to wear off and let their customers pay out of pocket to have this fixed. Some owners have had to replace up to 4 times in less than 40K miles.

SERVICE BRAKES
Front brakes (pads and rotors) had to replaced 2 times. The dealer said that Subaru used undersized pads and rotors on the bigger Ascent model. The brakes were not designed for such a big vehicle, and it has been a known issue. The brakes were replaced under warranty, but my warranty will expire soon. I'm stuck replacing and poorly designed braking system, that is a known issue.

LANE DEPARTURE: ASSIST, LANE DEPARTURE: WARNING
Vehicle drifts on the highway and pulls hard to the left, which is a very concerning safety issue. I have already taken the vehicle to the dealer; they did a calibration of the eyesight. The problem still persists, especially when driving the vehicle on the highway. This has almost pulled me into traffic on a few occasions!

The contact owns a 2021 Subaru Ascent. The contact stated that while making a left turn at approximately 5-10 MPH, another vehicle ran a red light and crashed into the front passenger's side bumper. The air bags did not deploy. The contact's chest struck the steering wheel, resulting in a fractured sternum. Medical attention was received. A police report was filed. The vehicle was first towed to the police impound lot, then to a body shop. The dealer was made aware of the failure and referred the contact to the manufacturer. The vehicle was not repaired and was not deemed totaled by the insurance company. The manufacturer was not made aware of the failure. The failure mileage was approximately 19,000.

UNKNOWN OR OTHER
After 3 years the battery died completely and the car was unable to start, I replaced the battery with AAA and the next the day, it also died again. I was able to jump start the battery the next day and continued to use the vehicle. I have the battery for about a month and again the battery on the vehicle had drained where I was unable to start the car but I was able to jump start the car with a battery jump starter. There has been 3 occasions of battery just draining and I have a new battery installed. I called Subaru and they mentioned that there could be an issue with the back latch no closing which could drain the battery, however, the have confirmed that the back door does completely close and lock or it will just automatically come back up. I feel there is something wrong with the electrical system and AAA has confirmed with me the the alternator or the battery is functional.

ELECTRICAL SYSTEM
The vehicle has a parasitic battery draw. I purchased a new gel cell (Redtop) battery, the most powerful one that fits the car, and was reimbursed by Subaru. The car battery still goes totally dead after about one week, even with occasional driving. I have to carry a jump battery in case I am traveling to insure that I can get the car started when I stop.

STEERING, LANE DEPARTURE: ASSIST
Vehicle wanders on the highway and pulls hard to the left, which is a very concerning safety issue. I have already taken the vehicle to the dealer, did an alignment and took it back a month later because the issue persisted. The problem persist, specially when driving the vehicle on the highway. I am really concern about my family safety and the safety of others in the road.

POWER TRAIN
Car has always refused to accelerate if gas pedal is pushed down too quickly. Just before 60K miles, on way home we had pulled over at a roadside stop on a hill. Tried to pull across highway to continue up road, car refused to accelerate and luckily were able to brake in time to keep from getting t-boned by big truck heading down the hill. No trouble lights came on, so weren't sure if this was operator failure from pushing gas down on hill or mechanical problem. Also were too close to 60K miles to get home and back to dealership without going over warranty and serious service issues with dealership previously, and leaving for vacation following day. Decided to see if there were further problems. Live at 8K elevation, vacation at half that. No further problems until after returning from vacation. Car definitely hesitating when cold to accelerate at 8K elevation. Checked owners manual, at this time believed appropriate 36K service at dealership had inspected CVT fluid as requested, and was a bit early for next inspection listed in book at 66K miles, but thought perhaps CVT fluid needed changed (did not expect transmission to be failing with such a new car, only a bit over warranty miles now). Because of previous with dealership, instead found ASE certified shop for CVT fluid inspection. Fluid at shop inspection was dark and needed replaced. Shop exchanged with OEM fluid, not Subaru brand. CVT functioned much better for a time, then got worse and not just hesitating with cold but also jerking. Called service shop to insure they had used correct fluid and amount, they had. Brought in to confirm and fluid level was correct. They suspected CVT was failing. Called Subaru of America and made appointment at suggested dealership different from purchase dealership, confirmed transmission failure. Dealership rented car for safety because of suspected CVT failure. Subaru refused to replace CVT under warranty and wanted $7K+ to fix after $3K "discount: Still no trouble lights.

First transmission was replaced after months of trying to get the issue diagnosed. Symptoms included severe hesitation when trying to accelerate, shuttering, and feeling of jerking between gears even though it's a CVT. This escalated to shuttering while driving on the highway. Because the problem was intermittent, my car spent a great deal of time in the shop trying to get a diagnosis. After much back-and-forth with Subaru of America, the transmission was replaced at 48,000 miles. I asked for an extended warranty beyond the 60k warranty due to the fact that it took so long to get the first issue properly fixed. They said no. Less than 3,000 miles later and I'm having the same jerking/hesitation issues. The dealership technician says he cannot duplicate the problem, and SOA still refuses to honor an extended warranty. My 60k warranty is almost up and I fear that I will end up paying for a new transmission or worse, end up in an accident due to the poor performance issues. Subaru will do nothing about this known issue.
