Power train, Feb 24, 2025, crash
I just recently had my car come out of park while running at the top of a steep hill. I had stepped out of my car to deliver paperwork to my client. I walked to and from my car approximately 75-80 ft. As I was approaching my car I heard a clicking or a release sound then it began to roll. I wasn’t close enough to stop it and it rolled down a neighbor of my clients driveway and eventually rolled over landing against a tree. When I arrived at my car it was still running. I have awd and I noticed the tires in the air were not turning as they should have if it was in drive. My car was obviously totaled. How do I have someone check my car to see if there was defect that caused it to come out of park? I must say I forgot to set my handbrake. But I feel the car should not have come out of park regardless. Could it have been the front axle shaft or anything else?

Driver seat began rocking. The dealer indicated it’s a problem they saw with other cars as well. The attachment to the rail you move your seat forward and backwards with, brakes. The dealer wants to sell you new brackets to make your car safe again.

I was experiencing a weird binding or lurching in my drive train which made my Subaru feel unstable. I am a mechanic so I investigated these symptoms online and found that a large number of Subaru owners with manual transmissions were experiencing the same issue......a failing viscous coupler was the issue. There were no warning lights or indications prior to failure A failing viscous coupler will not properly engage the front wheels when needed, causing reduced traction in slippery situations, increasing the risk of sliding or spinning out. Uneven power distribution: When a viscous coupler fails, it can lead to uneven power distribution between the front and rear wheels, potentially causing the vehicle to pull or jerk, especially during turns. Sudden engagement: In some cases, a failing viscous coupler might engage too aggressively, causing a sudden jolt or shudder, potentially leading to loss of control. I purchased and replaced this component at my own expense not knowing the magnitude of the issue. This is a definite safety issue that could lead to serious injury or even death. I have the old part in my possession, it failed around 85,000 miles. One of the mechanics in the Subaru forum said he had submitted a report to NHTSA but I didn't see anything on your sight. Thank you for your help. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

What component or system failed or malfunctioned, and is it available for inspection upon request? The USB A outlets under the head unit that allow connection to Android Auto and Apple CarPlay Yes it is available for inspection upon request How was your safety or the safety of others put at risk? The connection when hooked up to a phone is intermittent. This results in driver distraction whenever it disconnects due to trying to get it to reconnect. Especially when using gps apps this means the driver may be "lost" until it can be reconnected, which means they will try to get it reconnected while driving which is dangerous. Sometimes it goes in and out every 60-90 seconds. Sometimes it won't connect at all until the vehicle is power cycled or the head unit is reset but neither of these guarantees a stable connection. The issue is not fixed by replacing the USB cable or the phone with a brand new phone. The cables and phone do not have this issue with any other USB port that they have been used on (in other vehicles). Has the problem been reproduced or confirmed by a dealer or independent service center? Not on my vehicle but there are hundreds of reports online for years with multiple Subaru models where it has been. I could get it reproduced easily, just haven't had the time. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No This happens every day, at any speed, and has been happening since I got the vehicle at 20000 miles and there are 35000 miles on it now (approximately).

The contact owns a 2021 Subaru Crosstrek. The contact stated while driving at an undisclosed speed, the vehicle shut off unintendedly and failed to restart. The contact stated that several unknown warning lights were illuminated. The vehicle was towed to the dealer where it was diagnosed and determined that the battery had failed. The vehicle was not repaired. The manufacturer was notified of the failure and opened a case. The approximate failure mileage was 27,000.

Check engine light came on while idling. "Eyesight" tech turned off along with certain associated safety features. Next day, vehicle struggled to ignite. Came to a complete stop at an intersection, released brake, stepped on gas, and the car rolled forward as if in neutral and bucked up and down like a rodeo bull.

While driving in the left lane on a three lane highway (about 70mph) the car's automatic braking system engaged. The car would not accelerate creating a very dangerous situation on a congested highway at night. Luckily, we are able to navigate to a brake down lane without a collision. The check engine light, Eyesight light and RAB light turned on. The car would not function normally and was towed to a Subaru dealer (Patrick Subaru, Shrewsbury MA). Diagnosis was a failure of the Engine Coolant Bypass Valve P26A6. Other failure codes were: P0087, P2004, P2005, B2806, B2C22. I was told this is a known problem in Subarus of certain years, but, instead of recalling, the company has extended the warranty on the malfunctioning part. This incident happened without any previous warning and caused a life threatening situation for us and those around us.

On two incidents randomly and without warning the car failed to accelerate while driving in traffic on an open road and I had to coast to safety and put in park, then drive, then travel less than five miles home. Both times I immediately scheduled service with suburu with appointments about a week out. The car drove without incident while awaiting service. Service failed to replicate the problem, diagnose or remedy it after having the car a week and I was told“vehicle is operating properly at that time”. The second occurrence at the end of June was far more dangerous as I was traveling at a higher speed in heavy traffic on a multi lane road when it occurred Car is unsafe for me, passengers and other drivers. I risk being stranded. I have no sense of reliability or safety and the car is just now at 30k

While driving down the freeway, all the warning lights came on and the engine sputtered and cut out. As we were in the left lane on a busy freeway, it put us at considerable risk. We were able to get to the left shoulder and get towed off the highway. This was caused, I later learned, by a faulty electronic thermostat which caused the system to fail.

Suddenly warning light "Check Engine" came on along with Eye Sight malfunction warning. "i RAB off" "Check Engine" Automatic Emergency Braking not working. Yes, available for inspection. Not confirmed yet by dealer. It is the weekend. There were no unusual symptoms prior to ADAS malfunction.

While the vehicle is moving. There is a loud pop noise from under the car. Subaru of America said it is a weld that is cracked. This pop noise is also felt in the steering wheel.
Forward collision avoidance, Mar 18, 2024
Subaru Eyesight system engaged randomly with no forward obstacles. Dashboard lit up, signaled alarm, and brakes engaged causing the car's nose to bottom-out. This has happened twice, thankfully at low speeds and thankfully without another car rear ending me. I'm worried this will happen on the highway. Eyesight system is generally unreliable. Random lane departure warnings and obstacles detected where there are none.

This is not specific to the Crosstrek. Subaru's remote connect app "mysubaru" has a dangerous flaw. When buying a vehicle pre-owned, the previous owner may still have access to the car. Subaru's call center says it takes at least 5 business days for a "transfer of ownership" process to occur. More often, customers never gain access to their pre-owned Subaru. The main cause of concern is that the previous owner may still have access to remote start the vehicle! Imagine you park your Subaru in your garage overnight, just for someone to start it remotely. Carbon Monoxide is borderless and colorless! This problem will eventually KILL someone!

In early November 2023, NHTSA Recall Number23V755000 was issued for my 2021 Subaru Crosstrek. I was not notified by NHTSA or Subaru even though none of my contact info has changed since buying this new vehicle. I believe that this creates a potential safety issue if owners are not made aware. I found out through Carfax in early January 2024.

Check engine light came on while driving. All Advanced Driver Assistance Systems were disabled. Code is P26A3: Thermo Control Valve is faulty. This is a known problem and Subaru has addressed it by redesigning the Thermo Control Valve in 2021. Unfortunately there is no recall on the models fitted with the prior design that have a high rate of failure.
Engine, Sep 19, 2023, crash
The contact owned a 2021 Subaru Crosstrek. The contact stated that while parking and the brake pedal was depressed, the vehicle accelerated unexpectedly and collided with a wall. The collision was at the front of the vehicle. The air bags deployed. The driver sustained arm, leg, thumb, back, and nose injuries. Medical attention was needed. A police report was filed. The vehicle was towed to an impound lot. The manufacturer was not notified of the failure. The failure mileage was approximately 1,300.

There are occasional times (perhaps once or twice a month) where the vehicle does not respond with the expected acceleration of a depression of the accelerator pedal. Specifically, the vehicle "lags" when I depress the accelerator pedal. While I have not experienced a dire situation or collision because of it, I believe it might cause other drivers to experience a safety incident: a driver might want to perform a fast maneuver with elevated risk but not receive the expected acceleration. For example, I was once making a U-Turn with traffic oncoming about 2,000 feet away. I needed to make the maneuver swiftly but my vehicle lagged. I would like to report this issue in case other owners of the Subaru Crosstrek Plug-In Hybrid are also experiencing.
Engine, Sep 3, 2023, fire
Was driving on highway at approximately 65 mph. Check engine light came on. Engine started to stop responding to gas being given to car. Pulled off to exit highway approximately 1 minute after check engine light came on. At bottom of exit, car completely lost power. Attempted to put vehicle into park and wouldn't shift. Started to see smoke coming from engine and then shortly after started to see flames coming from engine. Immediately exited vehicle and called 911. No one was injured. Subaru indicated fire started as result of external influences. Insurance company's 3rd party auditors were not able to determine cause of fire.

The issue is the Engine Coolant Bypass Valve. This causes the Engine to not take in as much coolant resulting in the engine getting much hotter than it should, thus putting those in the car’s safety at risk. This could ultimately lead to a fire and/or cause the car to suddenly lose power. My car already refuses to go above 3000 rpm’s and is very laggy when driving. The car itself shows a code that the bypass valve needs replaced & the check engine has come on. However, Subaru has failed to acknowledge that this is an issue amongst most of their vehicles since 2020. This issue also disables the Subaru Eyesight which is in control of adaptive cruise control, pre collision breaking, and sway warning. With those features now disabled, the car has lost the Safety Package that Subaru boasts. I have read on many online forums that this has been an ongoing issue now for many customers, a bulk of which experienced total engine failure. This lack of responsibly is putting many lives at risk on the road every day. I hope this helps shed light to this issue to Subaru & that this part is recalled so that Subaru must pay for the repairs instead of the car owners. Also, the repair part is around $500 & maintenance must be done by Subaru which is another $400-500 for labor. My opinion is they are using this defect as a way to make easy money on many customers since 2021. Here’s a link to the Service Bulletin that has been created about this issue: https://static.nhtsa.gov/odi/tsbs/2022/MC-10208664-0001.pdf?fbclid=IwAR355WNLzftp3Qhmj7GnfmPFL9VODbDEbiT9X5Admr7n90YI4rTa4J5HSIk_aem_Aex4JIYKdhZ3n6Xh90f9w4zKu4TxFSO6LxpMIwO79FtzP1E3Y5TygVIAq_Ih4KxM6nc

Forward collision avoidance, Aug 16, 2023, crash
While driving on the highway in the slow lane (furthest to the right), traveling at approximately 50 mph, I came to be behind a tractor trailer. Before I had a chance to pass the tractor trailer, it switched lanes abruptly. My vision past/beyond (in front of) the tractor trailer was heavily obstructed by the massive vehicle itself, so I could not see that in front of the 18-wheeler there was a mid-size sedan traveling at approximately 5-10 mph in the same active highway lane I was in. I had almost no time to react, and neither the Automatic Emergency Braking system nor the Forward Collision Warning system engaged. Both of these systems should have activated to prevent the collision and/or minimize injuries and damage. I subsequently collided (harshly) with the aforementioned sedan.
