Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“The front windshield cracked near the rear view mirror about 30 days after purchasing the car. It was a horizontal crack and continued to spread in both the left and right directions each day. I did not fix it immediately due to covid-19 fears. In december 2020 I scheduled an appointment to get it fixed because it had grown to 1.5 feet long.”

“We are on our second Subaru Ascent, first one bought back for the same issue. Upon starting the car, the cabin will fill with a strong smell of raw fuel (not exhaust). The car will also fill with the smell if running while parked, remotely started, etc. The smell is also noticeable when turning off the car and on the outside of it.”

“A large crack suddenly appeared on the windshield of my 2020 Ascent, and expanded rapidly over the course of a few hours. I purchased the vehicle new in january 2020. Subaru will not cover the windshield under warranty. The cost to replace the windshield and re-calibrate the eyesight sensors is over $1,000 through safelite. I'm concerned that having an outside company re-calibrate the sensors will void the warranty, and the dealership could not provide any clarification. …”

“When I parked my car 3 days ago, my windshield was perfectly fine. Since parking it the car has not been driven. Tonight when I got in the car to drive to the store I noticed a crack in the lower passenger side of the window that was absolutely not there when I parked the car 3 days ago. The crack is large and very obvious, and it's something I certainly would have noticed. This windshield has cracked for absolutely no reason. The car has been garaged this entire time and the weather mild.”

“My wife and I purchased a new 2020 Subaru Ascent in january this year. From day one, the vehicle has been generating an excessive and potent fuel smell in the engine bay that is then pulled into the passenger cabin via the HVAC system while running. This smell is prevalent when walking around the outside of the vehicle while it is running; it is also noticeable after parking (and turning off) the vehicle in our garage as the garage fills with a raw fuel smell that takes several hours to dissipate. …”
