On March 30th I filed a complaint #11654561. Since that time the vehicle has progressively gotten worse. Traveling at approximately 55 mph the tires suddenly locked up/stopped rolling at normal speed, jerked the truck and I was flung forward. the vehicle would not go over 15 mph AGAIN! Then, on [XXX] I was traveling home approximately 65 mph and truck downshifted and wouldn't move beyond 20 mph. This is getting out of control that I continue to have transmission problems with this vehicle. Talking with a Ford representative he said many problems have been with the transmission conductor plate, there is a defect and having it replaced with any product other than the Ford piece seems to resolve the problem. This is incredible, Ford is telling me what the problem is and won't fix it. How many other people are going through this same problem and we as Ford customers are being scammed of safety repairs. My truck is invaluable to trade in and I'm terrified to drive it. Please, hear my distress and help with a recall to fix our vehicles. Additionally, I just bought this truck approximately 7 months ago. For the 1st 30 days all was OK but as soon as I started traveling at higher speeds this problem appeared. I am afraid for not only my safety but for other drivers if this truck continues to act not safe in traffic.

2017 F-150 Platinum Supercrew 4WD Recently Purchased from dealership, drove for 2k miles and started having engine knock. Did research and found identical sound, Cam phaser knock/rattle. This is still a high priority issue and a known issue as it can cause engine failure and manufacturer is unhelpful and unwilling to investigate and/or offer guidance. I talked to dealership that preformed the -??recall-?? previously and they stated that no part was replaced and ford issued a software update to use as a bandaid instead of a permanent repair. It will cost upwards of $6,000+ to repair through dealer and ford refuses to be of assistance. I am requesting that the NHTSA reinvestigate the issue and open back up a recall request to the general public due to it being a safety concern. If the engine implodes on the highway, it can cause a major accident and/or fatal injury to many drivers.

Transmission will change gears while driving. I can be driving 45 mph in traffic, truck will automatically shift and I'm now going 15 and cannot speed up. There is no warning lites on dash before issue occurs. Called dealership who had no solutions to offer. I cannot be the only one experiencing this issue from reading online forums and Ford needs to be held accountable for faulty equipment. This is a safety issue in traffic for my family.
