The first-year Ascent is the CVT gamble of the family SUV world — great packaging, iffy powertrain execution

Every documented failure, earliest first

Ordered by the mileage the problem typically appears. VERY HIGH confidence means it's tied to a documented NHTSA recall, and 3 of these are rated Critical.

0k–15k mi● Critical$0–$400VERY HIGH
Transmission hydraulic pressure sensor giving false readings, triggering safety system shutdowns and check engine lights (subject of NHTSA recall)
How to catch it: Confirm the TCM/pressure sensor recall (and the separate TCU programming recall) were both actually completed — many 2019s only got one of the two.
Source: documented (NHTSA recall)
20k–70k mi● Critical$4,500–$7,000MODERATE
CVT chain wear, front pump failure, or full CVT/transfer case replacement in unlucky units
How to catch it: Get the CVT fluid changed every 30k miles regardless of Subaru's 'lifetime fluid' claim, and buy an extended powertrain warranty if outside factory coverage.
Source: multi-source pattern (AI synthesis)
25k–50k mi● PlanvariesVERY HIGH
Low-pressure fuel pump failure causing stalling or no-start (recall part)
How to catch it: Check VIN against Subaru's recall lookup for the two separate fuel pump campaigns before buying — unfixed cars can stall unexpectedly.
Source: documented (NHTSA recall)
30k–60k mi● Watch$150–$500HIGH
Windshield wiper linkage/motor faults and related visibility complaints, one of the highest complaint categories for this model year
How to catch it: Test wipers at all speeds during test drive, including intermittent settings, before purchase.
Source: owner-reported (60 NHTSA complaints)
40k–90k mi● CriticalvariesVERY HIGH
Driveshaft center support bolts loosening (recall) leading to potential loss of drive or vibration
How to catch it: Verify the driveshaft recall was completed; a loose center bearing can cause a dangerous driveline failure at speed.
Source: documented (NHTSA recall)
50k–100k mi● Watch$300–$600MODERATE
Premature rear brake pad/rotor wear reported by multiple owners well before normal intervals
How to catch it: Have rear calipers inspected for sticking and use quality ceramic pads; some owners trace rapid wear to caliper slide pins seizing.
Source: multi-source pattern (AI synthesis)
60k–100k mi● Plan$0–$150VERY HIGH
PCV valve cracking, causing oil leaks or rough idle (recall part on 2019 models)
How to catch it: Confirm PCV valve recall completion; the aluminum valve is known to crack with age even if driving is light.
Source: documented (NHTSA recall)
