Subaru Ascent
Problems & Worst Years

Two clear themes define the early Subaru Ascent: windshields that crack without any apparent impact, and batteries that drain for no obvious reason. In 2019, the worst year on file with 249 total complaints, windshield cracking without impact tops the list at 65 reports, while three separate battery-drain complaint titles — parasitic draw (59), drain without warning (56), and drain during idle (10) — collectively outnumber the windshield issue and point to a persistent electrical draw problem across the model's launch year. A further 27 owners reported random engine idling issues. The 2020 model year, with 215 total complaints, shows the same pattern reordered: battery problems described simply as "repeatedly dying" lead at 72 reports, windshield cracking (spontaneous and without impact combined) adds 63 more across two titles, and 44 owners reported engine stalling or failure to start — a complaint serious enough to warrant a careful test start and drive on any specific vehicle you're considering.

Recall campaigns 19V855 and 19V856 apply to the 2019 model, and 21V955, 22V907, and 26V436 apply across both years in this data, so there's a reasonable chance any given used Ascent from this window has already had some of this addressed — confirm completed recall work through the dealer or a VIN lookup rather than assuming. Notably, 2019 shows zero safety-severity complaints in this dataset despite the higher volume, while 2020 has one, so raw complaint count here tracks more with a launch-year rough patch than an escalating safety concern.

Windshield cracking without a clear cause and unexplained battery drain are the two things worth asking a seller about directly, and a pre-purchase check of the battery's parasitic draw is a reasonable, inexpensive test. As always, these figures represent what owners chose to report to NHTSA, not a lab-measured failure rate, and a documented service history tells you more about any individual Ascent than its model year alone.
