NHTSA Complaint #11647776 — 2018 FORD F-150

I own a 2018 Ford F-150 with 56,000 miles, and I have been experiencing serious and unpredictable transmission issues. These problems first started around 48,000 miles, but at the time, I assumed it was normal behavior. However, the issues have progressively worsened, and by 55,000 miles, a wrench warning light started appearing intermittently. Symptoms: •While driving at highway speeds, the transmission unexpectedly drops from 10th gear to 1st gear, causing a sudden and severe deceleration. •The gear shifts are jerky, unpredictable, and rough, making it difficult to maintain control of the vehicle. •The wrench warning light appears occasionally but disappears quickly, making diagnosis difficult. •No diagnostic trouble codes (D DTCs) are stored or retrieved when scanned at multiple repair shops. •The issue happens intermittently, making it challenging to replicate on demand. •Started noticing issues at 48k miles, but they became significantly worse around 50k miles when the wrench light began appearing. •I called Ford to reset the radio/computer software, after hearing it might help, but it did not resolve the issue. •The unpredictable transmission behavior causes severe anxiety while driving, as I never know when it will happen again. Attempts to Fix: •I have taken my truck to multiple repair shops and Ford dealerships, but since no codes are present, they have been unable to diagnose or fix the issue. •Mechanics have checked for transmission recalls or software updates, but no clear solution has been provided. •I contacted Ford for a radio/computer software reset, hoping it might help, but this did not fix the problem. Safety Concerns: •The abrupt downshifting poses a serious safety hazard to myself and other drivers on the road, especially at high speeds. •There is an increased risk of accidents due to sudden deceleration and loss of control. •The problem occurs without warning, making it difficult to predict or prevent.
