Battery failed in first 6 months of owning the car. Battery was replaced at Gilman Subaru Selma Texas. Battery and relay at North Park Body shop during the repair for hail damage. The car was at this shop from April 20th 2022 until the middle of July 2022. The day the car was picked up the electronic door locks did not work. The car was taken to North Park Subaru to diagnosis and repair a faulty body control module. They have had the car since August 8th. After it was taken back to North Star Collision to try to remedy the issue. North Star Subaru would not honor a warranty claiming outsider influence. On August 15th I was informed that the battery malfunctioned for 3rd time. With exception of about a week and a half since April 20th. I have not had use of my vehicle.

I purchased the car new in January 2021. During the first several months there were no issues. After that, the "Infotainment" system which controls the sound, nav, hvac, etc. systems would suddenly go black and those functions would stop working. It would seem to reboot as a computer does when you restart it. That was distracting but mostly just annoying, lasting less than 30 seconds. I will call that a "soft reboot." That happened many times over the next few months. On two occasions, the screen would black out and not only those systems would cease to function, it would shut down cruise control and Eyesight. Call that a "hard reboot." This was very dangerous. In traffic at 70-75 mph when the cruise control suddenly stops working, the car decelerates immediately and quickly. There are no warning signs or messages; it just goes black and shuts down those systems. Cars following would quickly be within a dangerous proximity. Not a safety issue but a hard reboot also wipes clear some settings including the nav destinations. During that period I spoke with service managers at two Subaru dealerships who said that it was a common problem and Subaru had issued a "patch" that was supposed to fix it. I live approximately an hour from the nearest dealership and had some difficulty finding a time to take it in for the upload. Finally I took it in to Scenic Subaru in Mt. Airy, NC on September 9, 2022 to get the update, with around 22,500 miles into a 36,000 mile warranty. I left the dealership at approximately 4 p.m. headed for Winston Salem, NC, approximately an hour drive. Within 5 miles from the dealership it did a soft reboot. That happened two more times. I called the dealership to advise them but it was too late to return. Then, still within an hour from the dealership, it did a hard reboot, shutting down everything as I described above. It functioned properly until it did a soft reboot today, 220 miles after the update.
Crack in windshield rapidly developed into line of driver sight.
Wind shield very very weak cracks very easy I have had for 1.5 years, I am on my 6th windshield, if any thing hits the edge of the windshield it totally cracks. Also having battery issues. on my third battery care has 47 k miles.
Windshield crack developed and requires replacement for the third time in 18 months on a new car.
