Third-Row Seat Back Latches, Seat Recline Mechanism, Folding Cable Assembly
This is one of several documented Ascent problems we track, and it fits inside the broader Reliability & Common Problems guide. If you're weighing repair against replacement, cross-check the Subaru repair-cost database and any open NHTSA recalls on your VIN before booking a shop.
What goes wrong
The internal locking mechanism within the 60/40 split third-row seat fails to engage. This results in a seat that cannot be secured in the upright position. In the event of a collision or sudden stop, an unlatched seat back can fly forward, increasing the risk of injury to occupants and rendering the seat unusable for passengers or child safety seats.
Symptoms to watch for
- Seat back falls forward during braking or acceleration.
- Red indicator remains visible on the release handle despite being pushed back.
- Grinding or clicking noise when attempting to fold or raise the seat.
- Release strap feels loose or has no tension.
Root cause
Insufficient lubrication and premature wear of the internal pawl/spring mechanism within the seat back frame, often exacerbated by misalignment of the latch striker during production.
Buy time with these
- • Avoid slamming the seat back into the upright position.
- • Manually verify the seat is latched by pulling the seat back before allowing passengers to sit.
- • Lubricate the pivot points of the latch mechanism with silicone spray.
Permanent fix
- Replacement of the entire seat-back frame assembly or the internal latch mechanism with updated part numbers (e.g., 64350XC00A).
