I HAVE A 2021 SUBARU FORESTER, BOUGHT IN OCT. 2020. THE VEHICLE WAS PARK IN THE GARAGE. I WENT TO GET INTO THE CAR AND NOTICE FRONT WINDSHIELD CRACK FOR NO APPARENT REASON.
1/21/2021
WITH LESS THAT 800 MILES I CAUGHT A CHIP IN THE WINDSHIELD, SAFELITE REPAIRED THAT CRACK AND FILLED IT, THEN LATER THAT NIGHT WITH NO CARS AROUND ME ANOTHER ROCK HITS THE WINDSHIELD AND IT'S GOT A HUGE CRACK...THE CAR IS A 2021 WITH LESS THAT 800 MILES ON AND IT AND I NEED A NEW WINDSHIELD ALREADY!! I'VE OWNED CARS FOR YEARS AND THIS HASN'T HAPPENED. I FEEL THE GLASS IS DEFECTIVE OR WEAK.

WHILE PARKED AT WORK, MY WINDOW CRACKED ABOUT 10-12' RIGHT DOWN THE MIDDLE. IT LOOKS LIKE IT FORMED FROM A SMALL PIT IN THE WINDOW. EVEN THOUGH THE CAR IS MAYBE 5 WEEKS OLD, IT LOOKS LIKE THERE ARE A BUNCH OF THESE SMALL PITS ALL OVER THE WINDOW WHICH COULD BE A MANUFACTURING DEFECT. MY FRIEND HAS A 2020 FORESTER THAT HAD THE WINDOW CRACK IN THE SAME FASHION AFTER ABOUT 5 WEEKS OF OWNING THE CAR AS WELL. I HAVE ATTACHED A PICTURE OF THE DAMAGE TO THE WINDOW.

This is for a car only 18 days driven. Windshield cracked from bottom, under retaining gasket, with no strike, impact, or previous ding. Car hood flexes up and down, more than 2-inches, when large trucks pass in opposite direction. Automatic fuel stop at pump did not work properly, causing fuel spill one time, and underfill another time. Windshield visibility and possibility of total failure. Car hood could fly up and obscure visibility and break windshield. Have not contacted dealer or insurance company yet about issues. Windshield problem is a known defect for Subaru, and subject of many lawsuits. No warnings before problems.

ON MARCH 2, 2021 I NEEDED TO GET TO AN APPOINTMENT AND MY CAR WOULDN'T START, NOR WOULD MY FOB WORK TO EVEN OPEN THE DOORS. AFTER CALLING FOR ASSISTANCE THEY JUMPED THE BATTERY. THEN I BROUGHT IT TO SUBARU WHERE THEY DID A COMPLETE DIAGNOSTICS TEST AND FOUND THAT THE BATTERY WAS DEFECTIVE. I HAD BOUGHT THE CAR NOV. 25, 2020, ONLY THREE MONTHS BEFORE! THEY REPLACED IT WITH THE SAME KIND OF BATTERY. I WAS DISMAYED TO FIND THAT I HAD BEEN SOLD A NEW CAR WITH A DEFECTIVE BATTERY.

ENGINE

The vehicle gets a shudder at different speeds and it feels like it's either the transmission is slipping or its coming from the motor but it NEVER THROWS a Trouble Code so as the dealership says if its not throwing a trouble code they can't diagnose it until it does. So that's why I don't like these vehicles because no one know how to fix it old school by being a real mechanic and going old school to find the issue.

On 04/02/2022, several minutes after having filled the gas tank, I was driving at about 35 mph on a two lane road at constant throttle, when the engine suddenly lost power for several seconds before it regained acceleration. There was a pickup truck following me very closely and it swerved around me to avoid hitting me. On 04/13/2022 , several minutes after leaving my driveway, at about 27 mph on a two lane road, the engine again lost power for several seconds before resuming power. In the first case the engine was at operating temp., in the second case it was cold. I will take the vehicle to the Subaru dealer from whom I purchased it in a couple of days to evaluate the problem, which I consider to be serious. In both cases I was so surprised that I didn't look at the tach etc. 12,500 miles.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
13 Reports5% of totalPreviewing the first 2 complaint summaries.
While driving down a two-lane road at 50-55 mph, the car started beeping and said "obstacle detected" despite there being *no* cars in front of, to the side of, or to the rear of me. Also, there was *nothing* on the road (no roadkill, litter, or other debris). Immediately upon beeping, the speed abruptly dropped from 50 to below 15 in a matter of milliseconds. Had there been a car behind me, they would've either rear-ended me or had to swerve (possibly into oncoming traffic), and had the road been wet or slippery, I would've likely spun out, possibly into oncoming traffic. Had the incident occurred on the interstate, it is entirely possible that I could've been rear-ended by a driver traveling at full speed. Again, all of this over no physical obstacle and with nobody around. This isn't the first time that the crash mitigation system has been activated over no observable obstacle (in fact, similar incidents have happend at least thrice), but this resulted in the most severe and abrupt change in velocity and was particularly concerning due to the high likelihood that it could cause an accident if the event had occurred with someone behind me. Since the incident happened maybe two hours ago, it has yet to be inspected and it didn't cause an accident, but I no longer wish to own the vehicle as it's clearly not safe for passenger travel.

Rock damage to windshield. Subaru advises to replace with OEM glass to guarantee safety systems operate correctly making this a safety issue. The problem is that Subaru windshields are back ordered. There are two problems here. First, Subaru windshields are very susceptible to damage, perhaps more than others. Second, Subaru fails to maintain critical safety system parts.

WHILE PULLING INTO A PARKING SPOT MY FORESTER LUNGED FORWARD EVEN THOUGH I DID NOT HAVE MY FOOT ON THE GAS PEDAL. ALSO, WHEN PULLING AWAY FROM A TRAFFIC LIGHT, THE VEHICLE SOMETIMES FEELS AS THOUGH IT WANTS TO ACCELERATE EVEN THOUGH I AM NOT PRESSING THE GAS PEDAL TOO HARD.

I was coming out of my garaged ( car was facing forward) . The car seemed to hesitate as I tapped the gas pedal. I thought maybe this was because the car sensed the sides of the garage via the rear view mirror sensors. I am always careful when exiting my garage so as not to ding the rearview mirrors. I repeatedly tapped the gas lightly about three times but the car hesitated each time and did not want to seem to move forward. One last time I tapped the gas and the car bolted out of the garage jumped the curb across the street at an unexpected rapid speed. I did not have my foot on the gas pedal. The car lunged forward , crossed the street and hit the garage door and frame of the house across the street for me doing structural damage. I believe this to be unintended acceleration for which other Subaru models have experienced problems. The air bags did not deploy.

1. July 15, 2021 the brakes didnât fully engage three times. Twice within 30 minutes while driving to work and once on my drive home. 2. Unknown 3. Yes. Car was at dealership put through all kinds of tests and field engineer checked it out. They had me come out on Monday, 9 August and drive it with the head mechanic while hooked up to a computer trying to see if the problem replicated. 4. Yes. 5. Yes. Eyesight technology picked up there was a problem â light came on, a text and an email were sent to me. Subaru got the message too. A specific issue was not identified at that time. Vehicle was towed to dealership three days later. Subaruâs field engineer was called into examine vehicle. Apparently, he saw something he didnât like on a reading â it had to do with the AEB-autonomous emergency braking system. Dealership replaced the entire braking system and returned the car to my driveway on Monday, 16 August. I bought this car in February 2021 after much research to include the NHTSA recommendations.

on 7/9/22 @ 6:00p I was with my wife & 2 grandsons going into a diner parking lot. as I was slowly going into a spot the car suddenly and without warning accelerated causing the car to drive over a cement parking stop, over a 1foot high cement wall, through a chain linked fence which had privacy covering, down into a 12 deep ravine. after shutting off the car my grandsons, wife & myself had to crawl out through the rear hatch. when things quieted down we realized that none of the safety features were activated (anti-collision warning, anti-collision braking) I thank God no one was hurt. Subaru needs to look into this so in the future no one ever experiences this.

It was a very cold night on Dec. 21, 2022. I traveled out of town. I don't recall seeing or hearing anything hit my windshield. However, on Dec. 22, 2022 when I got back in my car, I noticed a very long scratch across the windshield. It is now Mar. 1, 2023 and it has gotten much worse. I am unsure how to go about getting it fixed because I cannot pay for the repairs.

Braking system sometimes is activated by a sign on the side of the road, by a tree if we are turning, or nothing at all. Nearly in 2 rear end collisions when the system activated incorrectly. We cannot drive into our garage with the system activated...brakes keep slamming on. The only safe way to operate this subaru is to manually turn it off every time we start the car. Subaru dealership states it cannot recalibrate the eyesight system as it does not have that ability. Dealership is in Corvallis oregon. Lane notification system also has issues in construction zones (it tries to steer the car into the water barriers marking the lane changes. At least the side warning system can be permanently disabled. We have filed many complaints with subaru to no avail. Promised return phone calls never happen, phone transfers to their technical department result in dropped calls. This system is dangergous!!!

My Forester needed new tires at 13,250 miles. I had my tires rotated and that is when Subaru noticed the worn tires. I called Subaru Corporate and they informed me that do not replace tires. I bought new tires and then went to have a wheel alignment. The technician told me he could do the alignment but he couldn't adjust the Lane assist diagnostic or the VDC and other safety features. Now I am unsure what to do. I have tried to resolve this with Subaru of America without resolution. Hopefully, you will be able to help me. Why are Subaru dealers not doing these adjustments?

The first incident occurred when I drove into a parking space, applied the brakes, and the car suddenly sped forward, so I had to repeatedly jam on the brakes to make the car stop. Fortunately, no person or vehicle was directly in front of me. In the past week, we have experienced problems with the ADAS. We were backing into a parking space at night and made contact with a parked car. Our car made no warning sounds or lights to warn us. The following day, the blind spot detector light went on and off intermittently, sometimes with an exclamation point, and sometimes without an exclamation point. The lights on the mirror did not come on when cars were approaching from behind. We are making an appointment with the dealer ASAP.

On my 2021 Subaru Forester the rear passenger wheel well rubber cover came loose during travel. This has happened on my wife's 2019 subaru forester on the driver rear, and the one on the passenger rear is coming loose. The part was slapping against the side of the car and if we had not pulled over and manually removed it it could have easily flown off the car. The driver side on my wife's car has been replaced, and a replacement has been ordered for my car. The local dealer stated that this has not happened before. To have two car suffer from this seems a bit suspect to me.

In the afternoon when I returned to my vehicle, a large crack (roughly 8 inches) formed on the lower sector of the windshield that appeared to have oriented by the mounting of the passenger wiper arm. I inspected the windshield for damage such as a rock chip and could not find anything to suggest that the integrity was compromised in any way. Their was no visible damage to the windshield other than the crack that formed. The crack formed while the vehicle was parked in a parking lot

STEERING

The automatic shut off feature causes the car to lose all power. No power at all in the middle of traffic and I can't even use hazard lights to warn anyone. When at a stop the auto shut off turns off the car and when I take my foot off the brake it completely dies. It has happened 5 times in the last 3 days. Very dangerous. Imagine this happening on the freeway during rush hour. It's a miracle if no one has been killed. I saw countless posts from others on different forums. I have only owned this car for a week and half, taking it to the dealer today. This needs to be a recall paid for by Subaru, it is unacceptable.

While driving on I-17 Southbound near mile marker 311 at approximately 75 mph, I experienced a sudden and dangerous malfunction of the Lane Keep Assist (Auto-Steer) system in a 2021 Subaru Forester. The feature was active at the time and unexpectedly veered the vehicle sharply toward the concrete wall on the left shoulder of the highway. I attempted to regain control, but due to the abrupt nature of the malfunction, I overcorrected and collided with the wall on the rear driver side. There were no vehicles in the immediate vicinity, or this could have resulted in a multi-vehicle collision at high speed. I hit my head during the impact but did not require emergency medical services at the scene. Road conditions were dry and clear, with no visible debris or extreme weather factors. There were no warning lights or error messages from the vehicle prior to or during the incident. The Auto-Steer system did not disengage on its own before veering off course. This was the first time driving this particular vehicle, which was a company car, and I immediately reported the incident to my employer. The damage was reported and the vehicle is seemingly available for inspection. At the time of this report, the issue has not yet been formally diagnosed by a dealer or service technician. The failure of this driver-assist feature significantly endangered my safety and potentially the safety of others had there been nearby traffic. I am filing this report so the issue can be investigated, and similar malfunctions prevented in the future.

I was going down a highway using the lane keeping assistance feature. Suddenly the vehicle stopped following the road and ran me into a ditch. I was able to steer back onto the road, but if the ditch had been deeper I believe there would have been a rollover accident. The root cause is that when the audio system is turned up in the vehicle, the warning chimes do not interrupt the music or sound loudly enough to be heard over it. When the vehicle needs manual intervention assistance staying on the road, the driver may not hear the warning sound in time before the system disengages. The warning chime sounds need to be able to be heard over the audio system. This exact thing has happened to me 2-3 times in the last year.

BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
1 Report0% of totalPreviewing the first 1 complaint summaries.
The RCTA system operates very poorly. When backing up and we see a car in the rear camera screen approaching from the back side of our car, we cannot hear or see any allert. My wife and I are both seniors in our seventies and I suffer from normal age-related hearing loss....my wife not so much. Her hearing is quite normal. But we cannot hear the alert alarm. Also, the visual alert is located in a place where you do not look when you are backing up. It wasn't until I owned the car for four months that I discovered that there is a visual RCTA alert in the side view mirrors (of all places)....an area one does not look at while backing up. With a car with a rear camera, your eyes are usually glued to the camera display screen when backing up; after all, it is a safety device. We have nearly had a collision a half dozen times already. I contacted Subaru about this issue, and they told me that there is nothing that they can do and that in their words "As you can imagine, finding the right balance for all of our owners is a difficult job." this sound alert should be adjustable...it is not. And the visual alert should be in a place where your eyes are looking when backing up. Right now, the Subaru RCTA is worthless to us.

EXTERIOR LIGHTING

I believe Low Beam Head lights must be carefully inspected in low light environments, when driving at around 60mph at 2 lanes highway where you cannot use high beam lights, the sight is clear at the sides of the road but its to low down at at the speed driven if something shows up at the road it would be impossible to see and to stop at a safe distance. I believe the lights from your car ahead are too low to the ground and the visibility is dangerously short, I think that problem should be revised carefully. When driving on a highway alone at night that concern can be seen and maybe understand what I want to say and why that can cause an accident.

Weâve been using our Gold Revolve 360 car seat in rear facing for 14 months with our daughter who just turned two on August 19th. After normal wear, no car accidents and removing the carseat from the vehicle only a handful of times for sleepovers at grandparents and Iâve noticed a tear in the right strap, so bad that is nearly cut all the way through. This is toward the bottom where the strap meets the seat. From what I can see, there is nothing for it to rub up on to cause this, and my daughter is not allowed toys while in her car seat that could potentially do this. This is our only carseat at this time and it is extremely concerning every time she rides in it. We spent far too much money for this to happen, especially just over a year of use. Iâve tried reaching out to Evenflo via phone, website contact support and have emailed 8 times. Their chat services on the website are never available, even during hours of operation. Iâve called the number provided to me when I got the automatic response to the form I filled out on the contact tab,1 (800) 233-5921, and was told to email only by a automated message. Then there was a different number listed on the website that was a fraud number, 1 (800) 223-5921. And have yet to receive an email back after being asked to send a list of specific photos for their engineer team over a month ago. At this point I donât feel safe putting my daughter in the car seat anymore. This shouldâve been the last car seat I had to buy for her until a booster seat. And it barely made it a year and cost me $400+. Iâm beyond frustrated by the lack of support Iâve received from Evenflo and the trust I had in this product.

Tire size: P225/60R/17 98T Was driving around a roundabout @ about 25mph. There was a "Bang" and the right front tire went instantly flat. At no time did the vehicle either hit an object on the road or a curb. Vehicle was pulled over immediately. There is no rim damage that might indicate a curb strike. Upon examination of the tire there is a 2 inch rip in the sidewall of the tire. The tires (4) had been installed on the car @ 20,988 miles. They had been rotated at 27,427 miles. The blowout occurred @ 33,721 miles (12,733 miles from installation. I was told that there is no warranty on the tire(s) since we were not the original owner of the car when they were installed.
