The Ascent's high-torque Lineartronic CVT (TR730 - the largest CVT Subaru has produced) paired with the 2.4L turbo FA24 engine exhibits hesitation from stops, harsh engagement when shifting from Park to Drive/Reverse, and surging at low speeds. The TR730 CVT must handle significa… Repairs typically run $0-$9,000. Severity: high.
Subaru recalled certain 2023 Ascent SUVs because the center support bolts for the driveshaft may loosen. If they back out, the front end of the driveshaft can disconnect from the vehicle. On a three-row family hauler like the Ascent, that is a serious defect: NHTSA states that se… Severity: high.
The Ascent's TR730 high-torque CVT develops valve body failures that cause erratic shifting, harsh engagement, and transmission warning lights. The valve body controls hydraulic pressure to the CVT pulleys and chain, and when solenoids or passages within it fail, the transmission… Repairs typically run $1,500-$8,500. Severity: high.
A misaligned bead guide arm on the tire mounting equipment at the assembly plant put excessive stress on the tire bead as tires were pressed onto 20-inch wheels. The stress damages the tire's internal structure at the bead, which is not visible from outside the wheel. Damaged bea… Repairs typically run $0-$0. Severity: high.
Owners of later Ascents report the EyeSight automatic emergency braking system applying the hydraulic brakes hard with no driver input and no obstacle present - on open highway, mid-turn, and while taking a curve. A proposed class action filed May 11, 2026 in the U.S. District Co… Repairs typically run $0-$400. Severity: high.
The Ascent has one of the highest rates of windshield cracking complaints of any Subaru model. Cracks frequently originate near the EyeSight camera housing or from windshield edges without any rock impact. The large windshield, acoustic lamination, steep rake angle, and EyeSight… Repairs typically run $600-$1,800. Severity: medium.
Ascents commonly experience dead batteries after sitting for 3-5 days without driving. The numerous electronic modules (Starlink telematics, EyeSight, keyless access, remote start receiver) create a high parasitic draw that depletes the battery when the vehicle is not driven regu… Repairs typically run $150-$400.

Severity: medium.
The Ascent is the heaviest vehicle Subaru sells but carries brake hardware close to that of lighter models, and owners repeatedly report steering-wheel and pedal pulsation under braking starting around 18,000-20,000 miles, worsening to a full-vehicle shudder by 20,000-30,000. The… Repairs typically run $450-$1,300. Severity: medium.
The Exhaust Pipe Front (EPF) on the FA24F-powered Ascent cracks at a weld joint, producing a rattling or fluttering sound from the undercarriage under acceleration.

Subaru is recalling roughly 541,000 vehicles, including every 2019-2026 Ascent, because the federally required certification label on the driver's door jamb carries an incorrect Gross Axle Weight Rating.
