2020 Subaru Legacy Driver assistance Problems

Windshield spontaneously cracked at top. I came outside in the morning after a temperature fluctuation and there was a crack at the top with one piece of the glass sitting lower… it has since grown. I have been forced to drive with the crack as Subaru will do anything to not honor a warranty, ever. The eyesight I am learning is necessary for the vehicle to avoid front end collisions and to properly deploy the airbag. The crack started in November, it’s almost August, and I cannot get it replaced under the warranty I paid. I see many people have the same problem. You can even see where the windshield cracked where an iPass was mounted from a temperature change. The wipers also cannot keep up with moderate rain, causing rain blindness in moderate precipitation and the lightest rain will turn off the eyesight causing a malfunction that will not assist in avoiding a collision. In addition, I will be complaining with the CFTC for the warranty issues. I cannot even get records of my warranty or service. Example: window regulator was a problem off the log, and salesman used it as an example, service won’t repair. I regret buying a Subaru, they claim to be safe and reliable with great service, I am only having problems that affect the safe operation of the vehicle and I paid all this extra for full bumper to bumper and they tell me that it doesn’t exist. In addition, that vehicle claims to get close to 30mpg, I am being completely honest when I say I had about the same mileage in a 1995 Cadillac Deville, and the mileage I got in a 2009 BMW twin-turbo far exceeded the mpg. I tried to get it repaired today under warranty. I was yelled at that it was an impact, and I wish I knew… would have said, “is it more likely that I’m lying or the company that’s been successfully sued 4 times for this exact problem is at fault?” Perhaps there was a light impact in the months AFTER it broke parked in a unheated garage.

Since last October when a software update was performed on the vehicle I have had multiple(8-10) instances where the EyeSight system caused the emergency braking to activate when no other vehicles were nearby and a crash was not imminent. Usually it has been when entering a left hand gentle curve with a guardrail nearby, but it has also happened going straight ahead. The audible and visual alerts appear and hard braking occurs. The braking is severe enough that on rain or snow covered roads a crash might occur. The dealer inspected the vehicle and claims they found the calibration was off but the problem has occurred 3 more times since the calibration. I have contacted the dealer again but they have refused to acknowledge the problem further.

The contact's wife owned a 2020 Subaru Legacy. The contact stated while his wife was driving approximately 3 MPH in a parking lot the vehicle suddenly accelerated and jumped the curb into woods and collided with a tree. The contact said his wife was not aware of any warning lights being illuminated. The vehicle front bumper and hood hit in the center and were both crumpled back about six inches. The contact hit the top of his head severely damaging the windshield on the passenger side and sustained minor cuts. Due to the sudden acceleration he had not been able to buckle his seat belt, additionally the airbags did not deploy. The contact was transported by ambulance to a hospital. The police were called, a report was written and the vehicle was towed to a holding lot. The vehicle was not repaired. The contact's insurance provider declared the vehicle a total loss. The manufacturer had been informed of the failure. The failure mileage was 16,200.

This vehicle is equipped with the Subaru "Eyesight" system which is a number of safety features like automatic cruise control, lane keep assist, and others. About once a week on average while driving the entire system will shut down and the screen will go dark. You lose the radio, bluetooth, navigation, and all the Eyesight systems. After about 30 seconds it will reboot and things will come back online but this is a major safety issue because you loose systems that help with safety. The dealership said it's a known software issue and there's nothing they can do until an update is available. I called Subaru USA customer support in September and they said an update would be available by the end of October and nothing was released. I called in early November and they said they were still working on it but had no release date.

1. The infotainment system crashed (happens often), which caused the touchscreen in the center control stack to turn black and become unresponsive. This also caused the EyeSight safety system, adaptive cruise control (with lane keep assist), and reverse auto braking to all shut down (my dashboard lit up with warning lights and errors). 2. Not only is this an annoyance, but having all of the safety systems in my car unexpectedly shut down is extremely unsafe, especially adaptive cruise control. Other functions of my car, such as the radio and climate controls are also inaccessible when this happens. 3. A Subaru dealer has replaced the touchscreen in my vehicle to try and remedy the slowness and crashing, but it did not seem to fix anything. My car safety systems have not shut down prior to this incident, but on this day (June 6th), they did when the system crashed, which was after the replacement. After waiting weeks to get a replacement which didn't fix anything, I felt as if I needed to go elsewhere for help with this issue. 4. Only the manufacturer has inspected this issue, and I've also emailed Subaru directly after this incident, as to which I have not gotten a response yet (emailed on Monday, June 7th). 5. The warning lamps (for EyeSight, reverse auto breaking, and adaptive cruise control) all appeared on my dashboard as soon as the infotainment system crashed on June 6th. Prior to this, my vehicle had no warning lamps. They went away a few minutes after the system rebooted (all while I was driving on the highway), and system functionality returned to normal. Other Notes: This vehicle only has about 15k miles on it, and is only 1 year and 3 months old. Issues like this should not be happening. Before the replacement of the touchscreen, I had issues with it being extremely laggy and crashing, but my car's safety systems never shut down before. This is a new issue, which prompted me to report it to NHTSA.

DRIVING HOME WHEN I NOTICE WHAT I THOUGHT WAS A BIG HIT THE WINDOW. SLOWED TO THE LIGHT AND I NOTICE IT WAS ACTUALLY A SMALL ROUND CRACK IN MY GLASS SO I PULL IN THE WALGREENS LOT TO SEE WHAT COULD OF HAPPEN. BY THE TIME I PARKED AND OPENED MY DOOR I SAW THE CRACK HAD MADE ITS WAY ALL THE WAY DOWN MY WINDOW, SO I LEFT THE DOOR OPEN TO SEE IF I COULD FEEL THE CRACK BUT NOTHING. I GET BACK IN LIGHTLY CLOSING MY DOOR TO HEAD 2MORE MILES TO MY HOME AND THE CRACK MADE IT'S WAY UP HALF WAY THEN ACROSS HALF WAY. MY HEART LITERALLY MELTED. WHY IS THIS HAPPENING. THE WEATHER WAS 70 AND THERE WAS NO IMPACT OR TREES OR ANY SPEEDING CARS TO HAVE CAUSED THIS. MAKES NO SENSE.
