The engine system on this vehicle experienced multiple failures, including severe knocking, power loss, and potential oil-related malfunctions. Despite repeated service visits to the authorized Ford dealership, the problem persisted. The dealership performed multiple repairs, but the issue was never fully resolved. The vehicle has been undrivable for over a year, during which I have had to rely on rental cars, borrowed vehicles, and eventually purchased cash vehicles to commute ‘ all while continuing to pay for the truck. This is a severe financial and safety burden for a vehicle sold as reliable. To this day, no clear resolution has been offered, and Fords internal support has repeatedly deflected responsibility or referred me to scripted call center processes. The vehicle remains parked, unable to be driven due to fear of catastrophic failure or causing harm to myself or others on the road. The engine should be fully inspected, and the failure reported as part of a broader pattern I believe exists across other vehicles with this powertrain. There were early warning lights, knocking, and oil issues documented during dealer visits. The dealer acknowledged repeated service cases but failed to offer a true fix or replacement. This is more than mechanical failure ‘ its a consumer safety and engineering accountability issue. I urge NHTSA to investigate the root cause and assess whether a broader recall or investigation is warranted.
