NHTSA Complaint #11717566 — 2017 FORD F-150

While driving my truck roughly 60 mph, I experienced a sudden and uncommandded shift from 6th to 1st gear for roughly 3-5 seconds. When this occurred the engine RPMs jumped up to near Red Line and I experienced a rapid deceleration. I was driving on a dry road with new tires and did not experience any wheel lock up or skidding. However, this could have very easily posed an extreme safety hazard to both me and other drivers around me had I lost control of the vehicle which would have been highly likely in less optimal conditions. The problem has not been reproduced by a dealer or independent service center and the components have not been inspected. While the downshift was occurring there were some lights that flashed on the dashboard. I believe it may have been a check engine light, but my focus was on maintaining control of the vehicle so I did not have time to focus on the lights. Once the engine shifted back to normal there were no remaining lights or cautions. The symptoms of this incident very closely match those discussed in the ongoing Investigation EA26001.
