Driver's seat frame (base) began intermittently popping which progressed to a consistent popping felt every time the vehicle cornered at speed or weight shifted in the driver's seat. The problem was confirmed by dealership and an adjustment made to the seat rail alignment pin. For several months, the problem appeared to be fixed. However, the problem ultimately returned with a similar popping noise. I allowed it to progress until the dealership could reproduce the popping noise in the driver's seat frame (base). The problem was identified the second time as a cracked weld in the frame near the point where the seat back and base are connected. The dealership ordered and replaced the entire seat frame with a new one. The mileage at the time of repair was 23500 miles. I am documenting the issue because I have noticed several others complaining on truck forums of popping in the seat frame. Also, I noticed the recent Toyota recall for a similar issue in other model cars.
