NHTSA Complaint #11626996 — 2014 FORD F-150

Reference Tracking # 11622306. I purchased my used F150 with 52,956 miles on 1/3/2020. Shortly after, I would occasionally notice an unusual gear downshift. Upon receiving Ford Recall 24S37 (NHTSA 24V444000) update for the powertrain control module, the check engine lite (CEL) came on. I called the Ford Recall ph#, and they told me to continue to work with the dealership that performed the update. Several times I returned to the dealership, they would reset it with diagnostics, yet repeatedly the P0299 code would return each time. Prior to the CEL coming on, the CEL was preceded by a stall on acceleration on small hill inclines, and worsened fuel mileage, and typically after towing my trailer. These things didn't occur before the update was installed. (Attachments)
